How this roofing estimate works
The calculator multiplies your roof area by an installed price per square foot for the material you pick, then adjusts for how complicated the roof is, how many stories it has, extra tear-off layers and decking repair. The rates reflect typical installed prices for tear-off, underlayment, flashing, drip edge, ventilation and cleanup.
What changes the price the most
- Material. Standing seam metal costs roughly two to three times as much as architectural shingles up front. See metal roofing and shingle roofing.
- Roof size and pitch. Steeper roofs need more safety equipment and time.
- Complexity. Valleys, dormers, chimneys and skylights all add flashing and labor.
- Decking. Rotted plywood has to be replaced, and you only find out for sure after the tear-off.
What this estimate does not include
Structural repairs, major chimney or skylight work, custom trim and metal work, permits where required, and gutters. If you are also replacing gutters, use the gutter cost calculator.
