How this works. Footprint × pitch gives the real sloped area; that's divided into
squares (100 sq ft each) with waste added for cuts. Costs are current U.S.
installed ranges (material + labor). Steep pitch and extra stories add an access surcharge; tear-off
covers stripping and hauling the old roof. Treat the result as a planning ballpark — a real quote depends on
your local labor rates, decking condition, flashing, permits, and inspection.
