In professional roofing, a “Square” is a standard unit of measurement equivalent to 100 square feet of actual roof surface area. Material costs, structural waste, and labor are almost always packaged and quoted based on price per square.

Pitch modifies cost in two major ways. First, a steep roof requires physically more materials to cover the same flat ground footprint. Second, labor climbs dramatically on steep roofs (7:12 slope and above) because workers must wear safety harnesses, move slower, use specialized scaffolding, and execute work manually to prevent slippage.

Yes. The “Tear-off” toggle estimates typical regional disposal costs. Additionally, we’ve programmed a dynamic base contingency buffer ($350-$650 depending on area scale) to represent city construction permitting, dumpsters, and initial structural waste layers.

An average residential roof replacement (1,500 to 3,000 sq ft) typically takes between 1 to 2 days of physical labor, assuming clear weather. Extreme slopes, composite slates, or complex structures could stretch this to 3-5 business days.
