What is a roofing square?
Roofers commonly describe roof size in squares. One square represents 100 square feet of roof surface. A 2,000-square-foot home does not automatically have a 20-square roof because garages, porches, slope, overhangs, and roof shape matter.
Why per-square prices vary
Material, labor, removal, height, access, slope, complexity, decking condition, ventilation, flashing, permits, and market demand can all move the installed cost.
- Architectural and premium shingles
- Metal or tile systems
- Steep or complex roof sections
- Tear-off, repairs, disposal, and permits
Use the address instead of guessing
The calculator estimates roof surface for the selected property and shows the number of roofing squares used for the planning range. That produces a more relevant starting point than multiplying the home’s living area by a generic rate.
Frequently asked questions
How many square feet are in one roofing square?
One roofing square equals 100 square feet of roof surface.
Is home square footage the same as roof square footage?
No. The roof can include garages, porches, overhangs, slope, and multiple sections that do not match indoor living area.
Does roof cost per square include labor?
Installed consumer pricing generally combines material and labor, but the exact inclusions must be confirmed in a contractor’s written scope.
