This quick rule helps roofers, contractors, and homeowners accurately estimate the amount of materials needed for any roofing project. Whether you're re-shingling a small shed or planning a full roof replacement, understanding what a square means in roofing is the first step.

📐 What Is a Roofing Square?

In the roofing world, a square is a unit of measure that equals 100 square feet of roof area. Rather than talking in square feet, roofers use “squares” to make estimating faster and more consistent.

For example:

If a roof measures 2,000 square feet, it would be 20 roofing squares.
