How to Calculate Roof Squares Like a Pro

If you're getting quotes for a new roof, it helps to know how to calculate roof squares. A "square" in roofing equals 100 square feet. It's the standard unit used to estimate materials and labor.

To begin, find the total square footage of your roof surface. Start by measuring the length and width of each roof section. Multiply those numbers, then add all the sections together. Divide the total by 100, that’s how many squares you have.

For example:
If your roof is 40 feet wide and 25 feet long, that’s 1,000 sq. ft. Divide that by 100 and you get 10 roofing squares.

It sounds simple, but many roofs are not just one flat surface. They have valleys, dormers, or multiple pitches. That’s why measurements can get tricky. Estimating roof pitch is also important, steeper roofs require more materials and labor.
