Roof replacement is one of the largest home repairs. The cost depends on the size and shape of the roof, the material you choose and what the roofer finds under the old roof. This page explains how the price is built.
Sifixit does not publish price numbers unless we can name a trustworthy source for them. This page explains how pricing works so you can understand and compare the quotes you receive.
How pricing usually works
A roof replacement quote is usually made up of these parts.
Tear off and disposal
Removing the old roofing and hauling it away. More layers mean more work.
Roof deck repairs
Replacing damaged roof boards found once the old roof is off, often priced per sheet.
Materials
Underlayment, flashing, vents and the roofing material itself.
Labor, permits and cleanup
Installation, the permit and inspection, and removing nails and debris.
What makes the price go up or down
- The size of the roof
- How steep and complex the roof is
- The roofing material
- How many layers must be removed
- Damaged roof boards
- Chimneys, skylights and vents
- Local permit rules and code requirements
Insurance and your costs
If a covered storm damaged the roof, insurance may pay for some or all of the replacement after your deductible. Roofs that are simply old usually are not covered, and some policies pay less for older roofs.
- Check whether your policy pays replacement cost or actual cash value for the roof
- Know your wind and hail deductible
- Photograph storm damage before repairs
- Ask the roofer to meet the adjuster
- Never let a roofer offer to cover your deductible
How to compare quotes
- Compare the same material and brand
- Check that tear off, underlayment and flashing are included
- Ask how roof board repairs are priced
- Compare manufacturer and workmanship warranties
- Check the permit is included
Warning signs in a quote
- A quote without an inspection
- No mention of how many layers will be removed
- A roofer from out of town after a storm with no local address
- A large deposit before materials arrive
- An offer to waive your deductible
Frequently asked questions
How can I lower the cost of a new roof?
Get several quotes, compare like for like, and fix small problems early so the roof lasts longer.
Does a steep roof cost more?
Usually, yes, because it takes more time and safety equipment.
Is it cheaper to roof over the old shingles?
Sometimes, but removing the old roof lets the roofer find hidden damage, and codes usually limit roofs to two layers.
Does insurance cover an old roof?
Usually not for age and wear. Storm damage may be covered, sometimes at a reduced amount for older roofs.
