One square of roofing covers 100 square feet. A square is the standard unit that roofers use to measure roof size. This makes it easy to calculate how much material you need for your project. The average U.S. roof is 2,647 square feet, which equals about 26.47 squares. Understanding squares helps you know your roof cost and material needs.

What Is a Roofing Square?

A roofing square is exactly 100 square feet. Roofers and contractors use this unit instead of regular feet.

Think of it like this: if you have a roof section that is 10 feet by 10 feet, that equals one square (10 x 10 = 100 sq ft).
