Metal Roofing Cost vs. Asphalt Shingles: Metal Roof Prices 2019

If you are a homeowner considering installing a new metal roof on your house, then undoubtedly, one of the burning questions on your mind is how much will it cost?

On average, you can expect to pay between $5.50 and $12.00 per square foot of metal roofing installed. Granted, this is a pretty wide pricing range, but you can expect a metal shingle roof to average between $7.00 to $10.00 per square foot installed, while a standing seam metal roof will cost between $9.00 to $12.00 per square foot installed.

Now, assuming the average cost of $10.00 per square foot of metal roofing installed on an average-sized roof, it will cost about $17,000 to install approximately 17 squares or 1,700 square feet of metal roofing on a typical house.

The low-end cost for steel shingles installed over-top of the existing roof would be around $14,500 for the same roof, while the high-end cost of aluminum standing seam would be about $19,500 for a comparable roof.

If you opt for a less-costly option such as corrugated or ribbed steel roof, your cost will likely fall within $3.00 to $6.00 per square foot installed, depending on the metal thickness (gauges for steel or mils for aluminum) and the quality of paint finish (acrylic vs. Kynar 500 or Hylar 5000) for the system being installed, as well as your home’s geographic location.


Important Points to Keep in Mind:

When it comes to residential metal roofing, you are not only paying more for a higher quality material than asphalt shingle, but you are also paying for a more costly, professional installation that requires specialized skills, expertise, and equipment.

Keep in mind that there are a number of factors that may influence your final price for a new metal roof. These include the type of metal and the roof style you choose, your geographic location, and the overall complexity of your particular roof.

1. What to Expect From This Guide

Our pricing guide will walk you through all the main factors determining the cost of a metal roof. You will learn how much you can expect to pay for most popular types of metal roofing materials and how much it will cost to install the system of your choice.

Once you understand how the pricing work and decide on the type of system you want to install, you can then confidently negotiate with any contractor, as well as shop around to get the best deal possible in your area, without sacrificing on quality.

Did you know? The Total Amount of Labor Required to Install a Metal Roof is the Most Significant Cost Factor!

A beautiful cabin with combination roof

As a general rule of thumb, the greater the square footage of your roof, the less you can expect to pay on a per square foot basis for your choice of metal roofing material, especially if you opt for standing seam panels.

Did you know? Small-size orders requiring less than 300 sq. ft. or three squares of custom-sized sheet metal panels can be surprisingly expensive!

If you have a complex roof with multiple cut-up angles, dormers, sidewalls, chimneys and/or skylights requiring metal flashing, then your total installation cost will be proportionally higher.

2. Why The cost of Labor to Install Metal Roofing is Inherently High Compared to Asphalt

One of the main reasons for the high cost of residential metal roofing is the high cost of labor required for professional installation. That’s right, installing a metal roof is a technically involved process requiring special skills, training, experience and equipment.

Unlike conventional asphalt shingle roofs, the installation of a metal roof must always be carried out in an accurately-measured and highly precise manner.

A metal roof is not simply nailed to the roof deck like its “ugly” cousin, asphalt shingles. πŸ˜‰ To install a typical metal roof, it can take up to two to three times longer than installing a comparable asphalt shingles roof.

To ensure the longevity of a new metal roof, the entire installation process must be carried out with proper technical know-how, precision, care and patience.

Standing Seam and Shingles Combo

The base price includes installation of premium breathable synthetic roof underlayment, along with basic, necessary pipe boots and roof vents.

A breathable underlayment will add an extra $30 to $40 to the cost of materials on a per square (100 square feet) basis. All the necessary trim and per-fabricated roof flashing is included in the cost of materials. One square equals to 100 square feet of the actual roof surface.

For instance, If you plan to install a standing seam roof, be prepared to pay more for the cost of labor, because standing seam installation can be quite technical and tedious compared to other types of metal roofing.

A typical installation price for a residential standing seam metal roof starts at around $9.00 to $10.00 per square foot or $900.00 to $1,000.00 per square installed. This figure does not include the cost of removing and disposing of the old roof.

Now, let’s take a look at the prices you can expect to pay for various types of metals and profiles including standing seam, steel shingles, metal tiles, stone-coated steel shingles, and their installation costs.

3. Steel

G-90 – Galvanized Steel: Hot-dip galvanized steel is the most affordable (after G-60 steel, which is used primarily in low-grade/low-end corrugated sheet metal panels that are commonly used for low-end roofing applications such as sheds, garages, some homes in rural areas, and lower-end industrial and agricultural applications) kind of residential metal roofing material offering a solid value to price performance.

G-90 steel coil or sheet steel is coated with with a thin layer of zinc oxide, which provides a reasonable degree of corrosion resistance and protection from the elements

G-90 steel panels are normally finished with Kynar-500, a paint finish known for high quality and longevity.

The following systems are usually made with G-90 Steel:

Interlocking Steel Shingles:

Materials will cost around $3.00 to $3.50 per square foot or $300.00 to $350.00 per square (100 sq. ft.) of painted steel shingles including trim. The base average cost installed starts at about $7.50 per sq. ft. or $750.00 per square, not including the tear-off.

Stone-Coated Steel Shingles and Tiles:

Stone-Coated steel roofing products are available in a wide variety of styles and profiles including tiles, slates, shakes, and shingles.

Material costs for stone-coated steel shingles and tiles range from $3.50 to $4.25 per square foot or $350.00 to $450.00 per square including trim.

With a professional installation, you would be looking at a total base price of about $10.00 per square foot or $1,000.00 per square, not including the tear off and disposal of the old roof.

Galvalume Steel – A measurable improvement over G-90 steel, Galvalume steel has a coating of corrosion resistant aluminum-zinc alloy applied by a continuous hot dip process.

Galvalume offers longer-lasting protection against rusting and corrosion from exposure to elements. Most higher-end, residential standing seam steel panels are manufactured from Galvalume steel, not galvanized (G-90 steel).

Steel Standing Seam: Prices start at around $4.00 to $4.50 per square foot of standing seam steel panels fabricated and cut to order at a local sheet metal shop, such as the ones available at Beacon Supply and ABC Supply.

To have a standing seam steel roof installed on a residence, your would be looking at an average cost of $10.00 per square foot or $1,000.00 per square, not including the cost of removing the old roof.


4. Aluminum

Aluminum is a step up in quality and longevity from steel. Aluminum is a more appropriate metal for homes based in near coastal areas. Aluminum provides longer-lasting protection from corrosion compared to steel.

Aluminum Shingles: Materials range in price from $3.75 to $5.50 per square foot or $375.00 to $550.00 per square of aluminum shingles including trim.

The average cost installed for aluminum shingles starts at around $9.00 per square foot or $900.00 per square for a basic residential roof, without the tear-off.

Aluminum Standing Seam:

Prices start at around $5.00 per square foot or $500.00 per square of aluminum standing seam panels fabricated and cut to order at your local building supply warehouse.

To have an aluminum standing seam roof installed on typical residence, you would be looking at a total starting base cost of about $11.00 per square foot or $1,100.00 per square, without the removal and disposal of the old roof.

5. Copper and Zinc

Copper is a premium quality metal and comes with a hefty price tag. You can expect to pay anywhere from $9.00 to $14.00 per square foot or $900.00 to $1,400.00 per square of copper shingles or standing seam materials, not including the cost of labor.

The cost of materials will range depending on the thickness and weight of copper shingles or copper standing seam pans. The cost of installation will also be significant, especially if you choose to go with copper standing seam panels requiring soldering of 16oz. or 20oz. copper pans.

The cost of a zinc roof is roughly 20% to 30% lower than copper, thanks to the lower cost of materials.

6. Paint Finish Quality Considerations

Today, you can get a metal roof in almost any color finish, with special paint coatings available in different grades ranging from low to premium quality.

Sheet Metal Roof on a Ranch House

It is often best to pay more upfront and step up to a premium grade. If this is for a home you want to be proud of, then aim for a Kynar-500 or equivalent paint finish.

Ultimately, it will be a difference of only a few hundred dollars, but you will have a longer-lasting, high-quality paint finish that comes with a lifetime transferable warranty, instead of getting stuck with a low-end non-warrantied paint finish.

In order to make an informed decision, make sure your contractor discusses a full range of paint grades and metal gauges available, and suggests the one that would be the best option for your home.

7. Colors

Most modern residential metal roofs are available in a wide array of energy-efficient, CoolRoof rated colors.

Generally speaking, the array of color choices is greater with standing seam, but metal shingles, tiles, and metal shake roofs do offer a wide selection of standard colors, as well.

8. Did You Know? Your Total Cost May Vary Greatly with Your Home’s Geographic Location.

The actual price of a new metal roof can vary quite a bit depending on your home’s geographic location. The cost of labor varies greatly in different cities and states across the US.

If you happen to live in an expensive coastal area such as Boston, New York City, Washington DC, Seattle, Miami, or San Francisco, the cost of labor for a roofing contractor will be a lot higher than in areas with a lower cost of living (LCV), such as Memphis, TN or Louisville, TN.

No matter where you live, it is critical to not cut any corners on quality by trying to save money on the cost of installation. Regardless of the price, you should only trust the job to an experienced and conscientious installer who takes pride in their work.

Durability and longevity of a new metal roof are largely a factor of its proper installation. So, it is best to hire the most-experienced installer to get the job done right the first time, rather than having to spend a lot of money on costly repairs down the road.

9. Why a Metal Roof is a Smart Investment in your Home and Environment

Thanks to its superior durability, longevity, and energy efficiency, a metal roof can be a smart investment in your home.

With an energy efficient metal roof, you can save a good chunk of “change” on you air conditioning costs over the summer.

Electricity savings of 20% to 30% are common for CoolRoof rated metal roofs during the peak AC usage months. Over the years, these savings will add up.

Durability, Longevity, ROI and Recouped Value

Another benefit of metal roofing is its superior durability and longevity. Metal roofs are built to last. While an average lifespan of an asphalt roof is about 17 years, a properly installed metal roof will easily last 35 to 50 years.

Have you ever seen what a hurricane can do to an asphalt roof? It can literally rip off all the shingles from the roof deck! πŸ˜‰ A properly installed metal roof will withstand most hurricane-grade winds, hail, snow and ice build-up.

In terms curb of appeal and beyond, a home protected by a metal roof not only looks beautiful, but its value increases and maintains for many decades to come.

A recouped value of a metal roof at resale hovers at around 90%. Meanwhile, a homeowner gets to enjoy the classic beauty of metal, along with substantial energy savings and often reduced home insurance premiums.

Green, Fully-Recyclable Material

For environmentally-conscious homeowners, a metal roof will often contain over 30% of post-consumer, recycled metal content, and unlike its “ugly cousin” asphalt shingles, a metal roof is fully recyclable. Every year, billions of pounds of asphalt end-up in our landfills.

Standing Seam Means Solar!

A metal roof can help you save money in more than one way. For instance, a standing seam metal roof is ready for a seamless PV solar system integration.

Thanks to the raised seams on the standing seam metal roof, PV solar panels can be mounted over the raised seams with the help of special S-5 holding brackets attached to the seams. In other words you don’t need to drill any holes in your shiny roof. Try doing that with asphalt! πŸ˜‰

    We had a standing-seam metal roof installed last year. There were enough left-over panels for us to create awnings over the windows (we’d do that ourselves; that was not a part of the contract).

    The roofing company came by after the installation and took all the left-over metal roofing. The contract mentions removing “debris.”

    Two questions:

    1. If I paid for the roofing material, why did the roofing company take it?
    2. What did the roofing company do with the left-over roofing material?

    When I mentioned to the roofing salesperson that our intention was to create our own metal awnings, we were told that the roofing company would be glad to sell us what we need.

    We paid $34,000 for the new roof (removal of old roof, too).

    1. The Roof Guy Post author

      Hi Rosemary,

      Have you paid for the standing seam panels separately or were the materials quoted separately from the whole job? How long were the left over materials left on your property for? Also, does the contract say that any left over materials belong to the contractor?

      Many contractors will include a clause saying that any excess or left over materials belong to the contractor, but if your contract didn’t explicitly say that, then you may indeed have the claim to the left over materials.

      Also, do you know how big your roof is and/or approximately how many squares of standing seam panels the contractor has ordered for the job in the first place?

  2. Mark


    I need a new roof and was considering the cool GAF architectural shingles or metal roofing. I live in Poway near San Diego.

    I have some questions that haven’t been addressed in the guide:

    1. How does metal hold up to being walked on compared to asphalt? And how do I walk on a metal roof?

    2. How do you attach Christmas lights to the roof? We usually attach lights along the edges and center ridges and also put inflatable displays on the roof with plywood propped to even out the roof.


    1. The Roof Guy Post author

      Hi Mark,

      1. A metal roof is perfectly safe to walk on as long as you wear rubber sole shoes and step in the middle of metal shingles of panels, not on the seams or edges of the shingles. Needless to say, you never want to walk on a metal roof that is wet or moist from the early morning condensation.

      In many ways a metal roof is better for walking than asphalt because you are not going to rip off any stone granules from shingles or carry the risk of stepping on a loose shingle.

      That said, walking on any roof is always inherently risky and should ideally be left to a pro.

      2. If you have snow-guards on a metal roof you can use them as anchors. You can also use metal pieces in between the gutters or gutters themselves as anchors to attach all-purpose light clips.

      If you have a standing seam roof, you could use the seams as anchors to attach the all-purpose light clips to as well.

      Some people also use fascia board and shutters to attach the light clips to.

      We hope this is helpful!

    I have a 1953 post and beam house with 2-inch tongue and groove vaulted ceiling. The current roof has rigid insulation and asphalt shingles using the tongue and groove as roof deck.

    All the roofers that we have had look at it insist on covering the whole roof with plywood if we go with asphalt shingles. Can metal roofing be installed without adding the plywood?

    1. The Roof Guy Post author

      Yes, for example, some standing seam metal roofing systems are available as batten seams, with metal panels being installed over wooden battens. You can also get a structural standing seam metal roof, which can be installed over framing. These options don’t require plywood.

    I have a Cape Cod (one & a half story) house. The asphalt roof started to leak inside the house at the top of a bow window’s inner edge on the first floor. Interestingly, it has stopped leaking during the subsequent rains.

    I checked in the crawl space on the second floor above the bow window and found no evidence of leakage there. I’m in Wisconsin, with temps already below freezing, so it’s too late for replacement and I was advised not to try repair/patching. I’d appreciate any advice or comments you can offer.

    My tentative decision is to wait until spring. If leaking begins again, I’ll simply have to deal with it by strategically placing buckets. I’ll appreciate any advice and/or comments you can offer.

    1. The Roof Guy Post author

      It sounds like the leak you describe may have been caused by a wind driven rain. It could be either a sealant failure around the bow window or asphalt shingles being lifted by the wind at the drip edge of the roof, resulting in leak.

      Without seeing the actual roof or pictures where the leaks occur, it’s hard to say.

      If the roof deck itself is dry with no evidence of roof leakage, we recommend checking the area where asphalt shingles overlap the drip edge.

      The asphalt shingles should extend beyond the drip edge. Make sure the shingles are properly secured, so they are not being lifted by the wind, exposing the drip edge and allowing the water leaks to occur.

      You should also check to see whether the fascia board below the drip edge is damaged by water leaking behind the fascia board.

      Also, if you happen to find any cracked or missing caulk around the bay window, we recommend using Solar Seal or similar sealant to reseal any areas that may be responsible for leaks.

      It’s true that you should not replace an asphalt roof in during fall / winter, because asphalt shingles won’t adhere to each other due to low temperatures.

      That said, a metal roof can be installed year-round if need be.

      Bear in mind that undiagnosed, ongoing leaks can cause costly damage to walls, ceilings, and insulation in your home.

  5. Shannon

    Hey there!

    We’re about to buy a fixer upper in Melbourne, Fl.

    The house needs a new roof and we know nothing about the roofing materials, etc.

    Are metal roofs a good idea regardless of where you live?

    Thinking of the possibility of hurricane damage specifically.

    Thanks, Shannon

      1. Erin

        Just drove to Florida last Monday, specifically to the areas of Port St. Joe and Mexico Beach which were hit by Hurricane Michael. I noticed many existing roofs with no damage were metal, while the same was not true of roofs with shingles. As I’ll be building in PSJ at some point in the future, it will be a metal roof for me!

        1. The Roof Guy Post author

          Thank you for sharing that Erin.

          Yes indeed, properly installed metal roofs will normally hold up much better than asphalt ones in hurricane prone areas.

  6. Debbie and Mark

    We are exploring some new roofing options for our home located outside of the Twin Cities area in Minnesota where we experience very hot summers and snowy, cold winters.

    We are currently evaluating GAF Timberline HD shingles and metal roofing.

    For metal roofing we are looking at several types including ribbed metal panels with exposed fasteners, standing seam, as well as aluminum shingles and shakes from Interlock and Classic metal roofing systems.

    It’s a two story house with two layers of old shingles that will need to be removed prior to new roof being installed.

    With the exception of the exposed fastener system, metal roofing estimates came in at a little over double the cost of asphalt.

    We are torn and seem unable to decide on which system would be the best choice for us. We would love to hear your thoughts regarding asphalt vs. metal for the Minneapolis / St. Paul area.

    1. The Roof Guy Post author

      Hello Debbie and Mark,

      Here is what we think: GAF Timberline HD asphalt shingles is a quality roofing option, as long as it’s installed correctly including chimney and skylight flashing, underlayment, ice and water shield, etc.

      Given the amount of snowfall the region receives, we recommend that proper consideration is given to ice dam prevention measures including roof ventilation and insulation during the planning and installation phases.

      That said, metal roofing would certainly be a sound choice for any home located in continental climate zone such as Minnesota.

      A properly installed meta roof would last two to three times as long as asphalt. Given hot summers and cold winters with a lot of heavy snowfall, our view is that a metal roof could provide significant energy savings during summer, while providing excellent protection from snow and ice dams during winter.

      Both aluminum shingles/shakes and standing seam are excellent choices. It’s the quality of installation that matters most. Both Interlock and Classic are known for their great product, but the quality of installation depends on the crew doing the installation.

      A standing seam metal roof should only be installed by a company that has ample experience and a proven track record of successfully installing this product. Checking contractor references and looking at some of their past jobs can help ensure you hire the right installer.

      A metal roof with exposed fasteners, a less-costly option, will require some maintenance every 15 to 20 years; Over time, due to thermal movement / expansion and contraction of metal panels, the screws will become loose, necessitating re-drilling of the holes to make them wider and replacing the old screws with wider ones, as well as applying new washers to go with the new screws to replace the dried-out or damaged old rubber washers.

      Our view: if the higher upfront cost is not a major concern, then going with either standing seam or aluminum tiles/shakes, depending on the shape of your roof and aesthetic considerations, would provide you with a durable and long-lasting roofing option, well-suited for the local climate. A quality installation is a must for a long-lasting metal roof.

      Good Luck!

  7. Deeann

    Hey Roof Guy! How does a metal roof stand up in the South Florida, one block from the ocean? EVERYTHING metal here starts to rust within a year or two, so wouldn’t a metal roof rust, too? Salespeople have assured us that it won’t, but confidence (in both the rust-proof-ness as well as being able to find the salespeople a few years down the road when it does start to rust) is low! Thanks for your advice!

    1. The Roof Guy Post author

      Hi Deeann,

      If you get a metal roof made out of aluminum or zinc, it will perform just fine, without any concerns as far as rust is concerned. Kynar 500 coated steel is also an option, however it will be subject to corrosion decades later. That being said, Galvalume steel will work better in a salt spray environment near the ocean than galvanized G-90 Steel. Here is more info on that:

      With standing seam metal roofing the quality installation is the key to a long lasting roof. So my best piece of advice is to hire the installer who will install a metal roof the right way in accordance with the local building code requirements.

      Good Luck!

  8. Patty

    Hi Roof Guy,

    I have learned so much from your site. We are considering replacing our 30 yr. asphalt shingle roof (only 12 years old) due to two leaks. We are looking at both metal and shingle roofs. What kind of maintenance is required on a metal roof with a 4:12 pitch? Our current roof has been needing constant moss removal and we are too old to keep doing it. Any help or suggestions you may have would be appreciated.

    1. The Roof Guy Post author

      Hi Patty,

      You really shouldn’t need much maintenance with a correctly installed metal roof. Moss won’t form on it. 4:12 is an appropriate pitch for metal roofs such as standing seam and metal shingles. Make sure your metal roof has a high-end coating such as Kynar 500 equivalent. The quality of installation and metal flashing details around chimneys and skylights are the key to a long-lasting metal roof. I also recommend using a breathable synthetic underlayment. Lastly, make sure you hire an experienced and proven metal roofing installer.

      Good Luck!

  9. Doreen Bramhall

    The Roof Guy,

    I have purchased my house 17 years ago with elastomeric coating applied to asbestos shingles. Twice since my purchase, I have had elastomeric coating re-applied to my roof. The roof does not currently leak, but my insurance company requires a statement every year that the roof will last 3 to 5 more years and I am anticipating the next time they will deny my coverage. The house is 92 years old and is historic. It has a gabled roof and is built of Dade County Florida pine. I want to replace the roof with a metal roof, but the cost of removing and disposing of asbestos roof tiles is considerable. Can a metal roof be installed over the asbestos tiles and if so what method do you recommend (plywood, batten or some other way?

    1. The Roof Guy Post author

      Hi Doreen,

      I’ve dealt with several asbestos shingles roofs in the past. Every time it was a real hassle! So, I feel your pain!

      You would have to coordinate the work between a certified asbestos removal company and a quality metal roofing company.

      I really don’t recommend trying to install a new metal roof over the asbestos shingles. Reason being is that there is a concern of added weight. Asbestos shingles are heavy. If you manage to mount a metal roof over the asbestos shingles with several liquid roof coatings, then the added weight of all of these roofing systems could become an issue. That being said, batten seam would be your best option, if you would like to try to install a metal roof over battens. If the crew succeeds in installing battens over the asbestos shingles, then this might be a viable option. Although, I still prefer the removal of the old roof option due to roof weight concerns.

      You should have the roof deck, roof frame and trusses inspected before installing metal over-top. Make sure the roof frame will be able to support the added weight. I know metal is light, bus asbestos, plus the layers of liquid roof do add up to quite a lot of weight.

      Good Luck and let us know how you make out!

  10. Jolene Tonn

    I am having a metal roof placed on my house, and I just found out that with a metal roof, I will be able to save on money on my utility bills, like air conditioning during the summer, but what about heating in the winter? I live in Minnesota.

    1. The Roof Guy Post author

      Hi Jolene,

      Home heating efficiency is primarily tied to how well your house is insulated. Having sufficient wall, floor, and attic space insulation is the key to maximizing your home’s energy efficiency over the cold season. A metal roof will help prevent any potential ice dam related issues during the winter, and that will be an important benefit in place that receives a lot of snowfall such as Minnesota, but again consider checking your home’s insulation levels to make sure that no heat energy is lost during the winter months.

      1. Sheila

        Hi Roof Guy,

        We’re also considering in metal roof in Wisconsin and have the same concerns as Jolene in the previous post. While I appreciate your point about ensuring that there’s adequate insulation, I’m still wondering whether a metal roof will make it colder inside. All things being equal, does a metal roof perform better in below freezing temperature than an asphalt shingle roof does, or will it be colder inside.

        Thanks for this terrific site!

        1. The Roof Guy Post author

          Hi Sheila,

          Your attic space is supposed to be cold via proper venting, regardless of the roof. — It’s a very important point. There should be ample attic floor insulation to keep the warmth inside the house.

          A metal roof is certainly a sound choice for colder climates such as Wisconsin, but no so much because of the temperature concerns, but rather because metal makes it easy for the snow to slide off the roof thereby helping prevent ice dams and damage to the roof and gutters.

          If you are concerned about warmth beyond walls, floors, and attic insulation, you can have insulated metal roof panels installed as well: — These are more for keeping the heat away from the house when it’s hot out, since the default is to keep the attic space nice and cold in winter or cooler in summer.

          If you don’t have an attic in your home, the thermal metal roofing panels will certainly help with keeping the warmth inside the house.

          Hope this clarifies the advantages of having a metal roof in a cold, snowy climate.

    Our present metal roof is 22 years old, concealed fasteners, and has started to fade in the last 15 months. The faded areas are in different locations, not equal fading, but a white color, and is no greater or less in fading depending on if it is a southern exposure or not. The roof works fine, LOOKS bad.

    We have a quote on it being professionally repainted, but feel that might be throwing good money after bad. The original product was through ABC, and was called Royal Lock. It was an architectural panel system, and pretty top of the line back in 1995.

    Any suggestions on what to do and where to look for knowledgeable sales and installers? Or any suggestions?

    1. The Roof Guy Post author

      Hi Pat,

      If there is no visible rust and no leaks, then repainting may be a viable way to go, if you can find a quality metal roof painter who can get as close as possible to Kynar 500 Paint finish in terms of coating quality. It’s important to keep in mind that painting should only be an option, if there is a good warranty being provided. Where are you located? Have you tried to find a metal roofing contractor to get some replacement quotes to see which option makes the most sense? You can use the free estimate form for that.

  12. Crystal L Cottrell

    Our old roof was heavily damaged from storms and our insurance is covering the replacement of a new one. We would like to go with a metal roof so it will last longer and we can try to avoid the hail damage again. How likely do you think it would be that the insurance would be willing to pay a little extra for us to use metal instead of the shingles which don’t last that long.

    1. The Roof Guy Post author

      Hi Crystal,

      I think it’s quite like they will pay for a metal roof, as long as you are willing to pay for the difference in cost between asphalt and metal. Needless to say, the metal roof itself would have to be approved by the insurance company. I think most standing seam and metal shingle roofs should qualify.

      Let us know how it goes!

    I have had damage to my existing asphalt roof from pests. I think the cause is raccoons. One hole in the roof is a half circle where the shingles and plywood are completely gone. The other hole may have been a broken limb, but could have been animals. My concern is if I replace the roof with the same type of roof, then I might have the same situation in a short period of time.

    Therefore, I am leaning toward a metal roof. I have a fairly good estimate for Galvalume Steel, 24 or 26 gauge standing seam material. I am almost ready to contract for this. My main concern is whether a metal roof, beyond the other advantages, will prevent raccoons and other pests, such as squirrels from destroying my roof again?

    No one I have spoken to seems to be able to actually state that a metal roof will be better in terms of animal damage. Additionally, will I be able to have a ridge vent with a metal roof? This system seems preferable. Thank you for your help.

      Hi Delores,

      Raccoons and squires won’t be able to eat through or break through a metal roof into your attic. However, if raccoons have a way to get onto the roof and run freely, there is a chance they may scratch and damage the paint finish with their claws. If the roof is steep enough, then this should not be an issue.

      As far as making sure that raccoons and squirrels stay away from your attic, metal roof will pretty much guarantee that these animals are not able to enter your home through the roof.

      Yes, you can have the ridge vent installed with a metal roof, provided there are also soffit vents in place. Ridge vent is essentially an air exhaust designed to work with the soffit vents aka the air intake.

      Hi Michael,

      The “Tear off” stands for the removal of the old roof. Typically, it will cost $1.50 per square foot to remove and dispose of the old roof.

      Given proper installation methods were used including deck prep, ventilation, and fastening, your new metal roof should indeed last for a lifetime of the house. Of course, you need to do your own due-diligence when choosing the installer, so that your system is installed by the book. That also entails proper selection of the system to install, flashing elements, underlayment selection, etc. It’s the whole system, not just longevity of individual panel that should be taken into the account.

    My husband and I are about to buy a house that needs a new roof. I want to install aluminum, he is worried that the sound of rain on the metal will be loud inside the house. The roof is gabled and the upstairs has two bedrooms with about 2 or 2 1/2 feet crawl space at the peek, but a portion of the downward slant has no space between the bedroom wall and roofing structure. We live in Austin, TX, so can get intermittent rain storms, not much hail, though. What is your experience of noise with metal vs. asphalt shingle?

    1. The Roof Guy Post author

      Hi Aphilley,

      When a metal roof is installed over the attic space or craw space, there should not be any noticeable noise. If there is no attic space, but a metal roof is still installed over solid sheathing such as plywood, or tightly-fitted boards, covered by underlayment, or better yet insulation over the solid sheathing, plus breathable synthetic underlayment, then the level of noise during rainfall should be minimal.

      The noise is only an issue if there is no solid sheathing underneath the metal roof, which was often the case with the “old school” shacks in the south, with their old tin roofs. Many old metal barns had similar issues.

      Hope this was helpful.

    You mention metal roofing is more specialized to install. Would a union sheet metal Journeyman with 17 years experience be suffice?

    1. The Roof Guy Post author

      Hi Jessica,

      Yes, I believe that’s plenty of experience with sheet metal for the job. Just make sure the installer is willing to familiarize himself with standing seam manufacturer’s installation specs. including underlayment, chimney and skylight flashing if applicable. I recommend using manufacturer-approved supplies such as underlayment, fasteners, etc.

    Nice article, a fairly neutral take on the cost factors of metal roofing. The elephant in the room that you ignored, was explaining the benefits of metal roofing, and why in many cases it ends up being the better value long-term — triple the lifespan of asphalt, energy savings, fire & impact resistance (which can lower insurance rates) and even weather-tight warranties that traditional roofing cannot offer. For the environment, traditional roofing is filling acres of landfill each year; metal is 100% recyclable, and therefore environmentally friendly. Metal roofs are about a third of the weight of traditional roofs. The benefits go on and on. It comes down to higher up-front costs, but much better cost-value across the life of the roof.

    I know this may sound dumb, but don’t you have to worry about hail damage on a metal roof? I can see the advantage of it lasting forever, but won’t it look terrible year after year that it endures hail damage?

    1. The Roof Guy Post author

      Hi Carol,

      Most modern metal roofs designed for residential uses are tested, rated, and warrantied to withstand hail. Most asphalt shingles roofs, on the other hand, would crack and fail when exposed to large hail.

      Metal is def. the way to go if you live in a hail prone area such as Oklahoma.

      1. doug107

        Agreed. The key to hail resistance is the gauge of the metal. Hail-prone areas should be advised to purchase appropriate gauge and profiles for satisfactory performance.

      2. Kris Hughes

        I lived in a house with a standing seam metal roof, in a hail prone area of Colorado. I never saw the slightest damage – even cosmetic – from ten years of hail storms. I don’t know the specs of the roofing, as it was installed before I bought the house.

    Probably one of the best metal roofing articles with follow-up comments I’ve ever read. Thanks for the info.

  20. Don

    Considering a metal roof and the contractor indicated that he would just go over top of asphalt singles? He would lay down fabric, then the metal roofing? Does this application method seem reasonable?

    1. The Roof Guy Post author

      Hi Don,

      It could be reasonable depending on the type of metal roofing system being installed, the shape of your roof deck, and how many layers of shingles there are currently on the roof. Generally speaking, you can do it with metal shingles, if there is only one layer of asphalt (two at most, if it’s allowed by the local building code) and the roof deck is in good shape with no major gaps in between the boards. You would not want any screws or nails to end up in the gaps/space between the two boards comprising the roof deck. — The concern is that with the installation of metal shingles of the existing layer of asphalt, you could essentially end-up with a whole raw of metal shingles being “secured” by nails that ended up being driven into the empty space between the boards, rather than a solid substrate such as tightly-fitted wooden planks comprising your roof deck or plywood. If that’s a concern, you could always perform a tear off, and then install plywood over the boards/deck before installing underlayment and metal shingles.

      With standing seam, it may not be a bad idea to remove the asphalt shingles first, as the longer standing seam panels have a tendency to expand and contract with temperature changes, which could cause the underside of standing seam metal panels to start rubbing against the sand granules on asphalt shingles. Overtime, this could lead to corrosion, if you choose to install steel panels rather than aluminum. Thus, I would not advice it with standing seam due to the expansion and contraction of metal panels rubbing against sand particles, as well as the telegraphing of shingles underneath the metal panels.

      For underlayment, I would recommend using breathable synthetic underlayment such as DeckArmor by GAF, not the regular felt underlayment used with asphalt.

      What kind of a metal roof were you thinking to install?

      1. Don

        I am looking at the Heavy Gauge G90 galvanized Steel coated with Kynar 500 PVDF flouropolymer finish metal roof.

        1. The Roof Guy Post author

          You can go over the existing roof with coated steel shingles, but I would not recommend it with standing seam, once again due to thermal movement. Also, if you are in salt spray environment or right near the ocean’s shore, such as a beach house, then consider going with aluminum rather than steel.

        2. doug107

          The Roof Guy is spot-on with his recommendations, although there are additional methods for roofing over shingles. The most common is to add battens to the roof, and constructing the new roof on the battens. This keeps the metal panels from contacting the old roof surface, and provides a small airspace which helps both with improved energy performance and reduced condensation. For a short read on the topic, go to:

      2. doug107

        Completely agree here. Battens could solve the problem of contact between the surfaces, but totally support The Roof Guy’s emphasis that your substrate must be solid and in good repair, otherwise you’ll be vulnerable to early failure. We don’t even sell felt, as the current synthetic underlayments are so much better and long-lasting. Nails are never a good idea for metal products, though, and recommend specifying screws specifically for the task. They will hold tight longer, and resist uplift better giving you a more weather-tight, secure roofing system.

        1. The Roof Guy Post author

          Thank you Doug, appreciate you mentioning the batten system as an option for constructing a metal roof in such a way that there is space/air pockets between the old surface and a newly installed metal roofing system.

    Given that different regions and geographic areas will have different prices, what is the cost difference in metal vs. asphalt in Pasadena, Los Angeles, and San Diego markets?

    1. The Roof Guy Post author

      Hello Martin,

      A typical standing seam metal roof for your average house in Pasadena will cost around $15,000 to $20,000 depending on the size and shape of the roof, number of storeys, and whether or not the old roof requires a removal. For asphalt, it would be roughly half the cost of metal, or $7,500 to $10,000 for a fully-warrantied and insured job by a licensed contractor.

      For comparison, a similarly-sized clay tile roof would probably cost twice as much as metal in Southern California, where clay tile roofs, with their “Spanish Tile” look are very popular.

  22. Lisa D.

    I am pretty impressed with your information. It is honest and realistic. It is not too often that there is someone that has the info and the knowledge that you have. We are a supplier of metal roofing and siding products and have a sister company that installs metal roofs (installation only). We just drove past a job that was being installed on a large fire company. The installation crew was pounding down the original standing seam and laying a new standing seam roof directly over top of the old one. I never saw this done and was amazed. I feel that this is a very poor application and nothing but a problem in the future. Your thoughts?

    1. The Roof Guy Post author

      Hi Lisa,

      This certainly sounds like the crew is trying to cut some corners, and this could potentially end up being a major problem in several ways:

      First of all, the metals could be incompatible; for instance, if the old roof was made of steel, while the new one is made of aluminum. — these metals should not be in contact as they will oxidize. There could also be some undiagnosed deck issues requiring repairs if the old roof has had any major leaks.

      Not sure how any storms or strong winds (uplift) will affect the new roof, as it may end up not being properly anchored to the roof deck, not to mention the issues with potential thermal expansion of the two metals being in contact, any resulting scratching of the metals from thermal expansion and contraction, and aesthetically uneven application of the panels, etc. – The building inspector may or may not approve the job if they learn about what’s underneath the new standing seam metal roof.

        Our current roof is about 11 years old. We’re considering changing our roof from asphalt to metal. We are in the Orlando, FL area.

        We sustained 85 mph winds last year during Hurricane Irma and the old roof is still with no damage. However, for the new roof, should we go with aluminum standing seam or aluminum shingles?

        What are the pros and cons of each?

        We have a single story home built in 1981, block, stucco construction. Currently, there are solar panels for the pool on about 1/3 of the roof.

        1. The Roof Guy Post author

          Hi Rita,

          In terms of pros and cons, both aluminum shingles and standing seam are pretty much on par. The key difference is that standing seam profile lends itself nicely to PV solar installations.

          With aluminum shingles, you will normally end-up having some holes in the roof in order to mount the solar panels.

          With standing seam, there is no need to drill any holes in the roof. Solar panels can be mounted over the raised seams of a metal roof with the help of special “S-5” brackets designed to attach to the raised seams. No holes in the roof, means there are fewer points of failure to worry about.

          Given that a third of your roof has solar panels, going with standing seam seems like the preferred route.

          Other than that, there are no real differences in terms of performance expectations. The quality of installation is still the single most important variable determining the durability and longevity of a metal roof.

          If you are installing a metal roof over the existing asphalt roof, then aluminum shingles would be a preferred choice, because with standing seam, there is a chance that old shingles might telegraph underneath the standing seam panels following the installation.

          With over-top installations (no tear-off), there is also a bit of a risk of standing seam panels rubbing over the old asphalt shingle granules due to thermal expansion and contraction of the panels.

          Another point of consideration is the shape of the roof. Standing seam panels are fairly easy to install on gable, hip, shed, saltbox, and barn style roofs.

          For homes with difficult and cut-up roofs and/or more intricate roof architecture, such as roofs with multiple towers, multiple dormers, level changes, etc. aluminum shingles can be easier to install, as they allow more flexibility during installation.

          In terms of aesthetic considerations, metal shingles provide more traditional look, while standing seam offers a more modern look.
