Homeowners usually get several roofing quotes, and they compare them line by line. A clear, itemized estimate is how you stand out from the one-line bids.
1. Inspect the roof
Check how many layers are on it, the condition of the decking where you can see it, ventilation, flashing around chimneys and walls, and gutters. Take photos; homeowners rarely see their own roof.
2. Measure in squares
Measure the roof's area in squares (100 square feet each), accounting for the pitch, then add a waste allowance for cuts, hips and valleys. Say the total number of squares on the estimate.
3. Name the materials
The shingle line or roofing material, underlayment, ice and water shield where it's needed, drip edge, flashing and vents. Clients comparing quotes need to see that they're comparing like with like.
4. Price tear-off and labor by the square
Tear-off and disposal per square (and per extra layer), installation labor per square, and extra for steep or complicated roofs.
5. Price the unknowns up front
You can't see all of the decking until the old roof is off, so give a price per sheet for replacing rotted decking. The homeowner knows the cost before you start, and there's no argument on the invoice.
6. Include permits, dumpster and cleanup
The permit fee, the dumpster or disposal, and magnetic sweeping for nails. List them so they're paid for.
7. Explain the warranties
The manufacturer's warranty (and whether it needs registering) and how long you guarantee your workmanship.
8. If it's an insurance claim, match the scope
Itemize the estimate to match the adjuster's scope so the homeowner can compare and submit it. Never offer to waive or pay the deductible; several states, including Texas, prohibit it.

Common mistakes
- A single total with no squares or materials listed.
- No per-sheet decking price, so rotted decking becomes an argument.
- Offering to cover the insurance deductible.
