Roofing Calculator

Use our free roofing calculator to quickly estimate your roofing costs, based on key inputs like roof area, material type, and labor charges. Perfect for homeowners, contractors, and builders.

Roofing Formula

Total Roofing Cost = (Roof Area × Material Cost per sq. ft.) + (Roof Area × Labor Cost per sq. ft.)
Example:
If the roof area is 2,000 sq. ft., material cost is $5/sq. ft., and labor cost is $3/sq. ft. → (2000 × 5) + (2000 × 3) = $16,000

Calculating roofing cost is as simple as multiplying roof area by material and labor costs. Not a fan of doing the math? Use our free Roofing Calculator to get instant results.
