Roof Replacement Cost Calculator

Estimate a planning range for asphalt, metal, tile, or flat roof replacement before comparing contractor quotes.

Starter planning range $8,500 - $24,500 Per project; final pricing depends on project conditions.

At a glance

Typical planning range $8,500 - $24,500

Per project before contractor-specific scope and site conditions.

Main cost drivers Roof area, roof material, roof complexity, and tear-off condition

These inputs move the estimate before local labor, access, permits, and project conditions.

Cost drivers to review

  • Roof area
  • Roof material
  • Roof complexity
  • Tear-off condition

How this estimate should work

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

Cost examples

Lower-scope roof replacement $6,400 - $20,800

A planning example for smaller or simpler roof replacement work with easier access, fewer upgrades, and limited prep.

Typical roof replacement $8,500 - $24,500

A planning example around the starter range when roof area, roof material, and roof complexity are near the middle of the project.

Higher-scope roof replacement $10,200 - $33,100

A planning example for larger, upgraded, or harder-to-access roof replacement work with more site prep or coordination.

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.

What should I enter in a roof replacement cost calculator?

A useful roof replacement cost calculator should account for roof area in squares, roof material, roof pitch and complexity, tear-off layers, decking repair allowance, disposal, flashing, ventilation, permits, access, and whether the project is asphalt shingles, metal roofing, tile, or a flat or low-slope roof system.

How much does a new roof cost?

A new roof planning range is usually $8,500 - $24,500 per project on GetCosts.com before contractor-specific site conditions. Smaller asphalt-shingle reroofs can cost less, while metal, tile, flat-roof systems, steep pitches, complex rooflines, multiple tear-off layers, decking repairs, code upgrades, and difficult access can move bids higher.

Does tear-off or decking repair change roof replacement cost?

Tear-off and decking repair can change roof replacement cost because labor, disposal, underlayment, fasteners, sheathing, flashing tie-ins, and inspection scope may all increase. Compare overlay, one-layer tear-off, and multiple-layer or decking-repair bids separately instead of treating them as the same roof replacement scope.

What should a roof replacement estimate include?

A useful roof replacement estimate should separate roofing material, underlayment, drip edge, flashing, valleys, vents, pipe boots, ridge caps, tear-off, disposal, decking or sheathing allowance, permit and inspection needs, site protection, cleanup, warranty terms, payment schedule, and exclusions for gutters, skylights, chimney work, fascia, soffits, or structural repairs.

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.
