If you like the modern style of raised metal seams and clean vertical lines on a metal roof, then consider installing this system on your home. A standing seam metal roof will not only compliment your home, but it will also give it that contemporary look and feel, providing unmatched durability, longevity, and energy efficiency. 😉
Standing Seam Metal Panels in a Nutshell
Standing seam is a high-end upgrade and an undisputed step up in quality and longevity from the classic corrugated and ribbed style metal roofs. Unlike its predecessor, corrugated steel roofing, which is still being widely used today for many commercial, industrial, and even some residential projects, standing seam has an improved design featuring concealed fasteners.
The ingenious design of standing seam metal roof featuring its characteristic raised seams, with no exposed screws in the roof, helps minimize the chance of a roof leak down the road.

How Does Standing Seam Compare to Metal Shingles?
Standing seam metal roofs can sometimes cost 20% to 30% more to install than metal shingles on more complex roofs. This is largely attributed to a more tedious labor necessary to install standing seam panels on a more complex roof with multiple dormers and valleys.
In terms of performance, there is no significant difference between the two systems, however the quality of your installation and strict adherence to your system’s manufacturer’s specifications is by far the single most important factor determining longevity and performance of any residential or commercial, high-end metal roof.
How Much Does it Cost to Install Standing Seam?
Total average cost to install a new architectural standing seam metal roof on a house can range between $10.00 to $16.50 per square foot or $1,050 to $1,850 per square, depending on the roof size, accessibility, home style, and project location. — This price range includes any required building permits, materials and supplies, professional labor, and workmanship warranty from the installer.
For a typical 2,000 square foot residential roof, it will cost between $22,000 and $37,000 to install standing seam. More, if there is also a detached garage to re-roof.
Cost of Materials
If you order less than 500 sq. ft. or 5 squares of custom-fabricated standing seam panels at your local metal fabrication shop, then your costs for the materials and trim will be around $5.50 to $7.00 per sq. ft. or $550 to $750 for smaller-sized orders.
Thus, it will cost between $2,750 and $3,500 for five squares of made-to-order standing seam panels and trim – enough to roof over that medium-sized front porch over a patio on your house.
For larger-sized orders, such as 1,000 square feet or 10 squares and greater, you can expect to pay about $5.50 per sq. ft. for custom-fabricated standing seam panels. For larger-sized orders, metal panels can cost less than $4.50 per square foot including trim.
There’s also the cost of matching metal flashing, such as starter and drip-edge flashing, metal coil for chimney and skylight flashing, snow guards for doorways and entrances, underlayment, and suitable screws.
All in all, unless you have your own roll-forming machine, you will need to go through a custom metal fabrication shop such as the ones at Beacon Supply or ABC supply. These places sell sheet metal panels and roofing materials to contractors only, so you will need to work with a professional contractor to buy the materials from a roofing supplier on your behalf.
Your total average material costs at these places will be around $5.00 per sq. ft. for a medium sized order of custom fabricated standing seam metal panels. For larger-sized orders, standing seam panels and trim can cost about $4.50 per square, depending on the color, metal thickness, etc.
For even larger orders, architectural standing seam panels in 26-gauge or 24 gauge G-90 galvanized steel finished with Kynar 500 paint finish can be ordered for between $3.50 and $4.50 per square foot including trim.
It’s true that you can also buy prefabricated standing seam metal panels at Lowe’s or Home Depot for about $2.00-$2.50 per sq. ft., but those panels could be limited to standard lengths, basic colors in polyester paint finish (not Kynar 500) and will normally be made out of the lower-end, thin (29-gauge) G-60 galvanized steel that is not suitable for residential applications.
For higher-end residential metal roof installations, you should aim for at least gauge 26 steel, or better yet 24- or 22-gauge (the smaller the gauge number the better — the smaller the number, the thicker the panel) Galvalume steel or aluminum panels finished with Kynar 500 paint.
All else being equal, Galvalume (zinc-aluminum coated steel) is considered a more premium and hence preferred option vs. the G-90 Galvanized steel (zinc coating only).
In most cases, Galvalume steel will outperform G-90 (galvanized) steel, all else being equal.
Note: Never buy low-cost metal panels finished with acrylic or polyester only paint finish for residential applications. — Unlike, Kynar 500 paint finish, acrylic and/or polyester paints will peel and fade.
Warrantied Professional Installation Costs
On average, standing seam will cost anywhere from $5.50 to $11.00 to install (professional labor and workmanship warranty, not including the cost of materials), depending on the difficulty of the roof and your home’s location.
Impressive Selection of Standard and Custom Colors
You can get a wide selection of standing seam profiles available in G-90 galvanized steel, Galvalume steel, and aluminum — all these metals are available in a wide array of standard and custom colors at major roofing supply warehouses such as Beacon Supply and ABC supply where they also have sheet metal fabricator shops.
Major roofing suppliers, such as ABC Supply, Beacon Supply, and Harvey Industries, normally have a wide selection of standard colors when it comes to sheet metal coils they have in stock — available for the fabrication of metal panels in any profile you choose.
However, if they don’t have the specific color you want from the catalog, they can get you a custom or premium color metal coil from the manufacturer, as long as you are willing to pay extra for the premium color, and don’t mind waiting a few weeks for the right color metal coil to arrive.
A key to a long-lasting metal roof is the quality of its installation, therefore make sure the installers you choose really know how to install standing seam and have plenty of past jobs to demonstrate their experience and expertise. — It may be helpful to speak to their former customers to make sure they are happy with the product and service.
Standing Seam is Loved by Residential and Commercial Building Architects
Many architects are especially fond of specifying standing seam for new construction projects, as well as for retrofitting existing roofs, thanks to the beauty, durability, longevity, and relative softness coupled with strength and flexibility of metal.
Standing seam roofs can also help improve the overall energy efficiency of a house, as well as help prevent ice dams during the winter months.
Commonly Used Metals and Alloys
Standing seam panels can be manufactured from a coated G-90 galvanized steel, Galvalume Steel (better quality than G-90 steel), bare and painted aluminum, zinc, copper, tin or terne, titanium, and stainless steel.
If you live near a coastal area, it is a good idea to opt for either aluminum or zinc standing seam roof to prevent premature corrosion and rusting that can arise from the relatively high concentration of salt spray in the coastal and marine environments.
Galvalume steel finished with Kynar 500 or Hylar 5000 paint finish is another durable and long-lasting option to explore for a home exposed to salt spray environment, such as beach homes.
Two Types of Standing Seam:
Field-locked (mechanically locked) standing seam requires special crimping tools to crimp down/lock the seams during the installation.
Snap-lock standing seam system is a bit pricier, but the seams can be locked by a simple snapping of the panels together.
Regardless of the type of system you choose to install, you will have to use manufacturer approved fasteners with every panel during the installation.
Standing Seam vs. Corrugated Metal
Standing seam roofs are generally made from thicker grades of steel than corrugated steel roofs. While many corrugated steel roofs are made using the thinner 29-gauge steel, a minimum of 26-gauge G-90 galvanized steel or Galvalume steel (better) is used for manufacturing of standing seam metal panels.
A 24- and 22-gauge steel (thicker and stronger/better grade than 26-gauge steel) can also be used for high-end residential and commercial applications including architectural (requiring a roof deck) and structural (requiring a suitable roof frame only) profiles.
A mid-panel stiffening technique is sometimes employed by the sheet metal fabricators, suppliers and manufacturers for a 16 inch and wider standing seam panels in order to prevent “oil canning” of the panels.
A metal coil from which standing seam panels are manufactured is usually factory painted with a high-end Kynar 500 paint finish. — this is unlike its close cousins corrugated and ribbed metal roofs (featuring exposed fasteners) that are often painted with cheaper, polyester or acrylic paints.
