A square of roofing contains 100 square feet. This is the standard measurement used by roofers and contractors across the United States. One square covers enough shingles to protect a 10 by 10 foot area of your roof. Knowing this helps you understand roof costs and materials. The average U.S. roof is 2,647 square feet, or about 26.47 squares. Understanding squares makes it easier to talk to roofers and get accurate quotes.

Why Do Roofers Use Squares?

Roofers use the word “square” to make pricing simple and fast. Instead of saying your roof is 3,000 square feet, they say it is 30 squares. This makes math easier on the job site.

Materials are also sold by the square. One square of shingles costs different amounts based on the type. According to RubyHome, architectural asphalt shingles cost $4.50 to $8.25 per square foot, which equals $450 to $825 per square.

How Long Will One Square Last?

Different materials have different lifespans. Asphalt shingles are the most common. According to RubyHome data on roofing longevity, basic asphalt shingles last 20 years, while architectural asphalt shingles last 30 years.

Metal roofing lasts much longer. Metal roofing can last 40 to 80 years. This means you may never need to replace a metal roof in your lifetime. Asphalt dominates the market. According to RubyHome, asphalt shingles represent approximately 80% of roofing projects in the United States.

What Is the Total Cost for Your Roof?

To find your total cost, multiply the number of squares by the cost per square. A typical home has 25 to 30 squares. According to RubyHome, the average roof replacement cost is $9,526. The range is $5,868 to $13,217 for most homes.

Labor costs add to material costs. According to the U.S. Bureau of Labor Statistics, the median hourly wage for roofers is $24.05 per hour. Your final bill includes both materials and labor. Getting multiple quotes helps you understand the true cost for your home.
