Price by the square, respect the pitch

Roofing sells by the square, but the number that sinks bids is pitch — a steep roof is more surface, more safety, and more time than its footprint suggests. Measure the true surface (footprint × pitch factor), price per square with tear-off and disposal built in, and add for layers, steep-charge, and complex cuts.

Questions

How much does a new roof cost per square?
Asphalt shingle roofing typically runs $350–$750 per square (100 sq ft) installed — materials, labor, and tear-off. A common 22-square home runs roughly $8,000–$16,000. Steep pitch, multiple layers to remove, and premium or metal materials push it higher.
How do I measure a roof in squares?
Roofing is sold by the "square" — 100 square feet of roof surface. Take the roof footprint and multiply by a pitch factor (a 6/12 roof is about 1.12× the flat area, a 9/12 about 1.25×) to get true surface area, then divide by 100. Our free satellite roof-measure tool does this for you.
