What a Roofing Square Is
The roofing square is the foundation of per-square pricing, and a Glenns Valley homeowner benefits from understanding it. Here is the picture.
One Square Equals 100 Square Feet
A roofing square is a unit of roof area equal to 100 square feet, so a 10-foot by 10-foot section of roof is one square. A square is 100 square feet. It is a fixed unit. A 10 by 10 area is one square. It is the standard. Roofers use it.
Why Roofers Use Squares
Roofers use squares because materials and labor are estimated by the square, which makes pricing and ordering consistent across jobs. They use squares. Materials are counted by them. Labor is estimated by them. It keeps pricing consistent. It is practical.
Counting the Squares on a Roof
A roofer measures the roof and divides the total area by 100 to get the number of squares, accounting for the pitch and shape. They measure the roof. They divide by 100. They count the squares. They account for pitch. It is precise.
Roof Area Versus House Footprint
A roof has more area than the home's footprint because of the pitch, so the square count reflects the actual roof surface, not just the floor below. Roof area exceeds footprint. Pitch adds area. The count reflects the surface. It is larger than the floor. It is worth knowing.

A roofing square is a unit of roof area equal to 100 square feet, and roofers use it because materials and labor are estimated by the square, counting the squares by measuring the roof and dividing by 100 while accounting for pitch, since roof area exceeds the home's footprint.
