Asphalt Shingle Roofs

Residential Asphalt Shingle Roof

Asphalt shingles (also called composition roofs) are a relatively inexpensive roofing solution compared with other options. In addition to the low cost, they are easy to install and durable. Asphalt shingles should last from 10 to 30 years depending on type, with homes in warm areas needing roofing replacement sooner than homes in cooler climates. They are available in two varieties — fiberglass and organic — and are manufactured in two different types: three-tab shingles (estimated 13-15 year life) and architectural shingles (estimated 17-20 year life).

Shingle Roof Cost

The average cost to install an asphalt shingle roof is anywhere between $1,700 and $8,400 depending on the slope, pitch and size of your roof. The material cost factors into that price, and as such shingle prices vary depending on your location and the specific product.

Here are some major brands and types with their average prices per square foot:

Installation Process

Due to slope, a roof generally takes up more square footage than the house it sits on, meaning you’ll need materials to cover more square footage than your house. For instance, an average size house is 1,500 square feet, but the roof could be up to 2,100 square feet. It’s typical to add on an additional 10 percent for waste on a simple roof project and up to 15 percent for a more complex and complicated installation job.

Building materials are generally sold by the “square,” and each square covers 100 feet. During installation for asphalt shingle roofing, a base is laid down first. The shingles are then nailed, tarred or locked into place so they overlap each other. You will need to adjust your asphalt shingle installation based on your climate, and of particular concern are areas in high-wind regions or on the coast. The Federal Emergency Management Agency provides tips for installing asphalt shingle roofing in these locations that require extra attention.
