Thus, on average, you can expect to pay about $4.50 per sq. ft. or $450 per square to replace an asphalt shingle roof on a typical single-family house.

The above price range will normally include the removal and disposal of up to two layers of old shingles. It should also include the installation of the new underlayment, chimney flashing, and ice-and-water shield at the eaves and valleys of the roof, as required by the local building code.

The average residential roof size in the US is about 1,700 square feet or 17 squares.

All roofers use “squares” to measure and estimate roofs. A square is equal to 100 square feet of roofing surface.

Based on the $350 to $550 per square pricing range, you can expect to pay between $6,000 and $9,350 for a typical 17 squares asphalt shingle roof replacement project.

For comparison, a 30 squares roof on a larger house will cost between $10,500 and $16,500 for a basic 30-year architectural asphalt shingle roof fully installed.

What About Prices for Other, Less-Common Roofing Systems?

While nearly 70 percent of all roofs in the US are covered with composition shingles (a composite of fiberglass mat, and asphalt and minerals/stone granules), there are many different roofing options for steep and low-slope roofs.

Below is a quick reference to help you compare average prices for the most common roofing systems based on a 17-squares residential roof:

Basic 3-Tab (25-year) shingles: $6,000 to $7,500
30-year architectural shingles: $7,000 to $9,500
50-year premium shingles: $8,500 to $12,750
G-90 steel shingles or stone-coated steel tiles: $11,900 to $17,000
Aluminum shingles: $12,750 to $18,700
Cedar shingles or shakes: $13,000 to $20,400
Standing seam: $14,450 to $20,400
Concrete tiles: $13,600 to $23,800 (roof-frame requires reinforcement)
Natural slate tiles: $15,300 to $30,600 (roof-frame requires reinforcement)
Synthetic shakes and slate tiles: $13,000 to $20,400
Clay tiles: $17,000 to $30,600 (roof-frame requires reinforcement)

Note that every market is different, but even in the same market, different companies will charge different prices. That’s why it’s important to get at least a few quotes from reputable pros in your area.

All else being equal, professional roofers in expensive coastal areas (such as homes in Boston, New York City, Washington DC, Miami, Los Angeles, San Francisco, Portland OR, and Seattle WA) will charge more for their services compared to roofing contractors in the south, mid west, or rural areas.

Asphalt Shingles Materials and Labor Costs

Many professional roofing contractors employ a “40% materials / 60% labor” as their costs-breakdown formula. Of course, this pricing structure is just a guideline not set in stone. Some contractors include their overhead in the cost of labor, while others calculate it separately.

Top 20 Roof Types and Pros & Cons – Roof Styles, Design & Architecture

It’s disappointing, but understandable, that more people don’t consider themselves “roof connoisseurs.” After all, most homeowners take their roofs for granted, as Bob Dylan put it, “shelter from the storm.” Oh, but accounting for only a mere 3% of the total house construction cost, a roof is so much more than that! 😉

Roof Types Diagram

Aside from material selection, what really gives your roof personality is its design and construction; how the peaks and valleys merge together. Some people might not be aware they had multiple choices regarding roof design, but here are 20 of the most popular roof styles and their associated pros and cons.

Flat

flat-roof

Most flat roofs are not really 100% flat, but rather they are low-sloped roofs that appear flat, but have a little bit of a slope to allow for the run-off of rainwater. Flat roofs are commonly found in modern architecture style homes, commercial buildings, or home additions such as a sunroom.

As the name implies, a truly flat roof would have no pitch, which could lead to the obvious problem of rainwater pooling up and creating a stagnant spa area for mosquitoes, bacteria, mold, etc.

The rainwater problem can be solved by centrally-located drains, scuppers, and gutters to evacuate the water. Asphalt shingles and other traditional roofing materials are not viable options for low-slope roofs. Low-slope roofs are instead covered either by EPDM rubber, single-ply membranes, and multi-ply membranes, or a tar/asphalt coating that provides water protection.

PVC and TPO roofs are also viable options to explore. – They offer better longevity and durability compared to EPDM rubber roofs.

Gable

gable roof

The term ‘gable’ refers to the triangular shape that is formed when the two pitched areas of your roof meet. It makes sense then that a gable style roof is basically one side up and the other side down similar to the roof on a traditional dog house.

Did you know? Roofing contractors love gable roofs, because gable shape entails covering only two flat surfaces without any hips or valleys, which means that virtually any type of roofing material can be used.

The gable design is available in almost any type of roof pitch, from low-slope ranch style homes to steep A-frames.

One of the only major problems with a gable roof is that they hang over creating eaves which are ripe for peeling off completely under strong winds.

Hipped

hip and dormer roof

One of the biggest problems with the gable roof style is that the two ends of the two house will have no shade or cover because there are only two roofing surfaces. A hipped roof is the style of a roof shape that fixes such a problem. A hip roof is defined as ‘when all sides slope downwards towards the walls’.

Hipped roofs usually have four sides – two with triangular shapes and two with trapezoids. One of the difficulties with a hipped roof is matching materials between the sides and ends. They do perform better in high wind areas however, especially the steeper the pitch.

Gablet (Dutch gable)

A casserole of roofs that solves the individual problems created in both the gabled and hipped design is the gablet (UK) or Dutch gable (North America) design.

A gablet basically puts a gabled roof on top of a hipped roof. The result is easier access to the lower portion (hipped) of the roof with the added benefits of natural light and attic or bedroom space (gable). Most types of materials can be used in a Dutch gable roof and in fact using variations in colors or types actually adds a nice contrast.

Jerkinhead

The jerkinhead design typically features mostly gable with a little bit of hipped influx mixed in. Gable roofs that are clipped into a short hipped design on the ends are structurally superior to wind uplift.

This design is frequently seen on the second story of a house where the clipped hip doesn’t disrupt the view from a dormer window.

Saltbox

A saltbox-style roof is one that’s popular in New England and other Northeaster states. The asymmetrical design is trademarked by the front of the home having 2 stories compared to one story in the back.

The look resembles a profile view of the old salt boxes which utilized that design so it was easier to pour.

The long protrusion of the rear roof portion extending almost to the ground makes it great for rainwater to disperse from.

One of the cons includes rooms on the backside of the house having slanted ceilings, limiting tall people to use essentially half the house. The saltbox does provide more wind resistance than a standard gable house though – perfect if you can get around the unique looks.

Catslide

A catslide is very similar to a saltbox style roof except that they are often only used in portions of the back roof or on home additions. Catslides extend beyond the eaves of a building, creating more depth at the cost of height. A catslide might be used as an extension into a mudroom/entrance or a transition into a three-seasons/sun room.

Dormer

A dormer isn’t necessarily an independent roof type, but more of an addition to an existent roofing style. A dormer is a window and a roof (gabled, hipped, flat, among others) that protrudes from the existing slope of a roof. Like some contractor’s tool belts a dormer can either be functional or just for show.

A functional dormer creates usable space out of the roof of a building, adding natural light and headroom. A false dormer is blocked off from the interior and is only used to boost curb appeal from the exterior. Dormers are usually, but not always, roofed in the same material as the house. To many roofing contractors they are a nuisance and an extra spot where a leak could arise, but for homeowners they serve as a priceless reading nook or way to get some morning sunshine. 🙂

Best Roofing Materials for Homes 2019: Roofing Material Costs, Pros & Cons

This comprehensive guide to roofing materials is all the research you need to evaluate the top choices for residential re-roofing and new construction projects in 2019.

Traditional PV solar panels on a new asphalt shingle roof

What to Expect: In this guide we’ll cover the following roofing options: asphalt shingles, wood shingles and shakes, metal roofing, concrete, clay, and fiber-cement tiles, natural and faux slate, and the new Tesla solar tiles that have so far proven to be more of vaporware than a real product.

For each residential roof type we cover the following topics:

  • An overview including how the roofing is made
  • Pros and cons including maintenance, repair, durability, options, home styles they work with and more
  • Cost for materials and installation
  • Choosing your roofing material/The “bottom line” summaries of each type
  • How to save money on a new roof

Types of Roofing Materials

These most common options cover more than 95 percent of residential roofs in the United States, so unless you’ve got something unusual in mind like solar tiles – oh, wait, we’ve included those – or a vegetative green roof, the options you’re considering are likely discussed here.

Asphalt shingles

More than 70 percent of all single-family homes in the US are roofed with asphalt shingles, though that number is slowly shrinking thanks to more energy-efficient and durable metal roofing.

Asphalt (composition) shingles dominate the market because they are affordable, offer a variety of attractive options and do a good job protecting homes from the elements.

There are two types of asphalt shingles:

  • Fiberglass shingles start with a fiberglass mesh mat that is covered in asphalt and topped with granules that provide color and reflect some of the sunlight. Shingles made with fiberglass are lightweight and resist tearing.
  • Organic asphalt shingles begin with paper, often recycled, that is saturated in asphalt and covered with granules. The shingles are heavier and harder to work with than fiberglass, but they generally offer better stability in high winds.Although you can still see them on many roofs, organic shingles have been mostly phased out or discontinued over the course of last decade. Why? Manufactures have stopped making organic shingles due to their tendency to dry out, become less-waterproof and more prone to excess moisture absorption.

Pros and Cons of Asphalt Shingles

The reasons to choose asphalt shingles are:

  • Fiberglass shingles offer good fire protection
  • Look good on most any style home
  • Shingles are often the most affordable roofing option, especially in good/better ranges
  • The best asphalt shingles are a 30-year roof solution installed on homes located in moderate climates
  • The cheapest 3-tab shingles are an affordable way to dress up a home before putting on the market
  • Broad selection of colors and styles including affordable three-tab and architectural shingles that mimic shakes and slate
  • DIY asphalt shingle installation is possible for those with good skills, experience and equipment
  • No support beyond standard roof sheathing is required for shingles
  • 3-tab shingles are rated for 60-70 MPH wind uplift, while standard architectural shingles are rated for 110 MPH winds; high-wind shingles are rated for 130 MPH
  • High-impact shingles such as the ones manufactured by GAF should be used for heavily-wooded locations and areas where large hail is possible
  • Some shingle repairs are easy and cost-effective

A few words of caution about asphalt shingles:

  • The lifetime cost of shingles is higher than metal, tile or slate, because composition shingles must be replaced more frequently
  • Cheap asphalt shingles last as little as 10-12 years in hot, sunny climates
  • Rapid temperature changes can cause asphalt shingles to crack
  • A poorly vented attic will trap heat and significantly shorten asphalt shingle lifespan by cupping or cracking them
  • While the asphalt shingle industry boasts that its products can be recycled for paving, few recycling facilities take asphalt shingles, and they are among the least eco-friendly roofing options
  • After a second layer of shingles needs replacing, all layers must be torn off the roof, creating extra expense and a lot of potential landfill waste
  • Mold or algae can be a problem on shingles in shady areas, unless treated with anti-algae/anti-stain treatments
  • Organic/felt shingles are heavy; getting them to the roof in bundles can be a challenge

Wood shingles and shakes

Wood delivers a natural dose of beauty to any roof. Cedar, redwood, cypress and pressure-treated pine shingles and shakes are available.

How are wood shingles and shakes different?

  • Wood shingles are machine-cut and feature cleaner edges and a smooth surface to produce a more uniform appearance.
  • Wood shakes are hand-cut from blocks of wood, so have a more rustic appearance. They’re thicker too, so slightly more expensive than wood shingles.

Pros and Cons of Wood Shingles and Shakes

The advantages of wood shingles and shakes are:

  • Wood has natural beauty that ranges from rustic shakes to handsome, neat shingles
  • Cedar and redwood contain oils that make them naturally resistant to moisture and insects
  • Treated wood shingles have a Class A fire rating
  • They can last 5 to 10 years longer than asphalt, which makes them competitively priced with asphalt over their lifespan
  • Wood has an insulation value twice that of asphalt shingles (but your home’s insulation levels are far more important than the R-value of the roofing)
  • Many shakes and shingles are made from salvaged trees – those that have fallen over from age or toppled by storm
  • Wood is recyclable into wood chips, mulch or compost
  • They enhance a range of architectural styles including Tudor, Victorian, Cape Cod, bungalow and cabin/cottage

Keep these disadvantages in mind when deciding on wood shingles and shakes:

  • Non-treated materials have a Class C fire rating, but wood can cedar shingles and shakes are also available as a more-costly treated option
  • Wood roofing is prohibited in some areas prone to wildfire, so be sure to check with your building department first
  • Untreated wood shakes and shingles are high maintenance – they need to be cleaned consistently to prevent the growth of algae or moss, and debris needs to be cleared to allow the wood to breathe
  • While DIY installation is possible if you have good experience, faults in the installation can lead to quick deterioration of the roof which often includes serious leaks
  • Staining of the shingles and shakes might occur as natural factors cause tannins to be released from the wood
  • While wood is quite durable, but repairs will be expensive if they are required
