How this calculator works
This roof replacement cost calculator estimates a practical roofing budget before contractor inspection. It supports measured roof area or a home-square-footage estimate, pitch, material, tear-off, region, and complexity.
Formula and assumptions
If roof area is not provided, the calculator estimates it from home square footage and pitch. It applies material cost per roof square foot, tear-off, region, and complexity factors, then splits typical cost into material and labor components.
FAQ
Is asphalt shingles the default?
Yes. Asphalt shingles are the default US planning baseline because they are common and cost-effective.
Does home square footage equal roof area?
No. Roof area depends on footprint, pitch, overhangs, garage coverage, and roof shape. Use measured roof area when available.
Does this include decking repair?
No. Hidden decking damage, ventilation upgrades, and code work can add cost after inspection.
Why does tear-off matter?
Removing old roofing adds labor, disposal, and sometimes additional repairs, so it affects total cost.
