How this roof estimate works
The calculator starts with an installed cost-per-square-foot planning range for the selected roofing material, then adjusts for pitch/complexity, building height, local market level and tear-off. It is intentionally transparent rather than pretending to know a contractor’s exact bid.
What can move a real quote?
Decking repairs, flashing, ventilation, underlayment, disposal, permits, access, warranty, product brand and local labor can all change the final price. A low quote may also exclude items that a higher quote includes.
Best way to use the number
Use the range to establish a budget, then compare at least three itemized quotes with the same scope. Ask each contractor to identify exclusions and allowances in writing.
