Roof Replacement Cost Calculator
Estimate a planning range for asphalt, metal, tile, or flat roof replacement before comparing contractor quotes.
At a glance
Per project before contractor-specific scope and site conditions.
These inputs move the estimate before local labor, access, permits, and project conditions.
Ask contractors to separate included work, allowances, exclusions, and change-order rules.
Estimate your project cost
Most roof replacement projects are priced by roof size, material, pitch, tear-off needs, and local labor costs.

How this estimate should work
- Estimate roof scale from square count and translate it into the labor and material area contractors quote.
- Apply material ranges for asphalt shingles, metal roofing, tile, and low-slope roof systems.
- Adjust the range for pitch, tear-off, access, decking repairs, disposal, and regional cost pressure.
- Show a planning range and route quote-ready homeowners toward contractor comparison.

Roof replacement cost by roof material
| Roof material | Planning range |
|---|---|
| Asphalt shingles | $8,500 - $24,500 |
| Metal roofing | $14,000 - $40,400 |
| Tile roofing | $18,700 - $53,900 |
| Flat or low-slope system | $10,600 - $30,600 |
Common questions
How much does roof replacement cost?
A typical roof replacement planning range is $8,500 - $24,500 per project. Final pricing depends on roof area, roof material, roof complexity, tear-off condition, local labor rates, access, permits, and project conditions.
What changes a roof replacement estimate the most?
The biggest changes usually come from project scope, especially roof area, roof material, roof complexity, tear-off condition. Contractor availability, code requirements, site access, disposal needs, and regional cost pressure can also move the final quote.
How should I compare roof replacement bids?
Ask each contractor to price the same scope, materials, timeline, cleanup, warranty, and permit assumptions. Then compare what is included, what is excluded, and how each quote handles surprises.

Compare contractor bids
Often included
- Labor and standard materials for roof replacement.
- Basic site preparation, cleanup, and disposal assumptions.
- Standard contractor scheduling and project coordination.
May cost extra
- Changes related to roof area, roof material, roof complexity, or tear-off condition.
- Permits, code upgrades, access issues, repairs, haul-off, or special-order materials.
- Scope changes discovered after the contractor inspects the site.
Confirm before hiring
- Whether the bid is fixed-price, allowance-based, or subject to site conditions.
- What is excluded, what could trigger a change order, and how surprises are priced.
- Warranty terms, payment schedule, start date, and cleanup responsibilities.
When to request quotes
Use the estimate after you know roof area, roof material, roof complexity, and tear-off condition well enough to compare the same scope across contractors.
Good time to ask
- You can describe roof area, roof material, roof complexity, and tear-off condition without guessing.
- You have photos, measurements, or notes that show the current roof replacement scope.
- You are ready to ask at least two contractors for the same included work, exclusions, warranty, and change-order rules.
Wait until you know more
- The project scope may change after an inspection, repair decision, insurance review, or permit requirement.
- You are still deciding between roof replacement options that would create different material, labor, or access needs.
Before you request quotes
Use these questions to describe your project clearly and compare contractor bids against the same assumptions.
