Roofing cost per square explained
Contractors often quote in squares. Understanding that unit helps you compare bids apples-to-apples.
What is a roofing square?
One square equals 100 square feet of roof surface area. A 2,000 sq ft roof is about 20 squares — though pitch multipliers can increase effective area.
What is a typical cost per square installed?
Architectural shingles commonly land near $450–$750 per square installed in many US markets. Impact-rated, steep-slope, or premium underlayment packages push higher.
Does pitch change the square count?
Yes. Steeper roofs have more surface area than the same footprint on a low slope. Estimators apply pitch factors when converting footprint to squares.
Are accessories included in per-square quotes?
Clarify whether drip edge, ridge vent, pipe boots, and ice-and-water shield are in the per-square price or listed as add-ons.
