Estimate Review
Roofing Estimate Guide (2026)
Roofing estimates are easiest to compare when every contractor is pricing the same scope. If one estimate skips important line items, the total can look cheaper while shifting risk back to the homeowner.
Direct Answer
A useful roofing estimate should list roof size, material, tear-off, disposal, underlayment, flashing, ventilation, decking repair allowance, permits, workmanship warranty, payment terms, and cleanup.
Roofing Estimate Line Items
| Item | Range / status | What to know |
|---|---|---|
| Roof size | Measured in squares | One roofing square equals 100 sq ft. |
| Material | Product line and warranty | Brand, shingle type, metal profile, or membrane system should be named. |
| Tear-off and disposal | Included or itemized | Extra layers can raise labor and dump fees. |
| Decking repair | Unit price required | Ask for per-sheet or per-sq-ft pricing. |
| Permit and inspection | City or county dependent | The estimate should state who pulls and pays for permits. |
Estimate Comparison Checklist
- Put roof size, material, and tear-off assumptions side by side.
- Check whether flashing is replaced or reused.
- Ask how ventilation corrections are priced.
- Confirm payment schedule and lien waiver process.
- Keep storm-damage and insurance conversations documented.
Weak Estimate Signals
- Only a total price with no scope.
- No warranty details.
- No decking repair allowance.
- No contractor license or insurance clarity.
FAQ
How many roofing estimates should I get?
Most homeowners should get at least three written estimates with the same material and scope assumptions.
Can a roofing estimate change after work starts?
Yes, especially if hidden decking damage, extra layers, or code corrections are found. The change-order process should be written.
Should permits be included in a roofing estimate?
The estimate should state whether permits are required, who pulls them, and whether permit or inspection fees are included.
