Roofing Giant · Free tool
Estimate what a new roof costs in Dallas–Fort Worth in under a minute. Enter your home’s footprint, pitch, stories and the material you are considering; the calculator applies Roofing Giant’s published fair-market DFW price book to produce a planning range.
Cost-planning path: use this calculator for a planning range, the Instant Roof Estimate for an address-based first look, and Roof Financing for payment planning.
Tool context: this calculator is a planning tool, not a bid. See Roof Replacement for scope, Roofing Materials for system choices, and all Roofing Giant calculators and tools.
How the calculator works
Roofers price by the square, which is 100 square feet of roof surface. The calculator converts your ground-floor footprint into roof surface using a pitch factor (a 6/12 roof has about 12% more surface than its footprint) and a shape factor for hips, valleys and dormers, then adds 10% waste for cuts and starter courses. That order quantity is multiplied by the per-square rate for the material you chose, with adders for extra tear-off layers, second-story access and steep pitch.

Frequently asked
Why is the range so wide?
Two homes with the same footprint can differ by 30% in roof surface once pitch and complexity are counted, and the same shingle can cost more on a steep two-story home than on a low ranch. The calculator narrows the range as you enter more detail; the instant estimate narrows it further by measuring your actual roof.
Does insurance cover a new roof?
If a covered storm damaged the roof, your homeowner’s policy pays the replacement cost minus your deductible, subject to the policy’s settlement terms. Try the deductible calculator to see how the numbers fall on your policy.
Is financing available?
Yes. Roofing Giant offers financing options for roof replacements; see the financing page or ask your specialist during the inspection.
