Estimate cost for durable and long-lasting metal roofing
A new roof is a major investment. This calculator factors in pitch and waste.
Tear-off: Removing old shingles adds $1-2 per sq ft. Steep Pitch: Roofs steeper than 6:12 cost 20-50% more due to safety requirements.

A new roof cost depends on square footage, material, roof pitch, tear-off needs, and labor rates in your area. Looking at both cost per square foot and total project cost gives a clearer estimate.
Start with the building footprint, then account for roof pitch and design complexity because the true roof surface is usually larger than the home’s floor area. That is why roofing estimates often use squares instead of simple room dimensions.
Many asphalt shingle estimates convert roof area into roofing squares, then into bundles based on the product coverage. Waste, hips, valleys, and cuts can increase the bundle count.
If damage is isolated, repair may be enough, but widespread wear, leaks, or an aging roof often make full replacement more cost-effective. Comparing short-term repair cost with expected remaining roof life helps guide the decision.
