Roofer Calculators

Shingle repair, metal roofing, flat roof coatings, gutters, ventilation, inspections — every calculator a roofer needs to quote complete jobs and not leave scope money on the table.

Roofing Quotes That Win Jobs and Protect Margin

Roofing pricing lives or dies on accurate square footage, material cost, pitch factor, tear-off complexity, and waste calculation. Get one of those wrong and the job that looked profitable at quote time is a break-even at best by the time you are cleaning up. The calculators on this page handle the math — from a quick asphalt repair to a full standing seam installation.

The biggest pricing mistake roofers make is quoting material cost at today supplier price without accounting for the 30-45 days between quote and purchase. Build a contingency into your markup or include a material escalation clause in contracts over $15,000.

Start with the Roofing Square Footage Calculator for accurate measurements, then move to the material and installation calculators to build the full quote.
