Roof Replacement Cost Calculator: what to expect
Roof replacement cost tracks with roof size (in squares), pitch, and material. Tear-off of old layers and the complexity of valleys, dormers, and penetrations add labor that a simple square-foot price hides.
Across the United States, a roof replacement cost averages $23,666 once mid-range materials, licensed labor, and standard permits are included. The figures below are a national baseline; pick your state or city to apply local labor rates, material delivery costs, and permit fees.

What a roof replacement cost includes
- Tear-off and disposal of old roofing
- Underlayment, flashing, and ice/water shield
- New shingles or panels
- Ridge vents, boots, and penetration sealing
- Permit and final inspection
What drives the cost the most
- Roof size (squares) and pitch set the labor baseline.
- Material — asphalt, metal, tile, slate — spans a wide price range.
- Number of layers to tear off and disposal fees.
- Complexity: valleys, dormers, skylights, and chimneys slow installation.
Budget, standard, and high-end scopes
The $12,476–$49,696 range maps to three common levels of finish:
| Scope | Roughly | What it covers |
|---|---|---|
| Asphalt (3-tab) | $12,476 | Most affordable, ~15–20 year life. |
| Architectural shingle | $23,666 | Standard upgrade, better durability and look. |
| Metal / tile / slate | $49,696 | Premium materials with long lifespans and higher labor. |
How to save on a roof replacement cost
- Replace before leaks cause deck and interior damage — repairs compound.
- Bundle gutter and skylight work into the same mobilization.
- Get the tear-off count verified; hidden layers change the quote.
How this estimate is calculated
We start from a base cost-per-sqft for roof replacement cost and adjust it for finish quality, labor complexity, waste, and equipment, then apply national baseline indices. The figures update with the cost data and reflect mid-range, licensed-contractor pricing, not a binding quote.
