A roofing quote should read like a construction scope — not a flyer. After years of homeowner cost guides, contractor vetting traffic, and product research on RoofingHut, the pattern is clear: the lowest number rarely itemizes tear-off, decking, underlayment, or permit. This page teaches you how to read a bid like a project manager.

Anatomy of a usable quote

Every serious bid should list:

  • Squares and waste factor (e.g. 28 squares + 10% waste) with roof pitch and stories.
  • Tear-off layers (1-layer vs multi-layer) and haul-off / dump fees.
  • Decking allowance — $/sheet for plywood/OSB replacement, not vague “as needed.”
  • Underlayment system — ice & water locations + field underlayment type (underlayment guide).
  • Flashing — step, counter, valley, drip edge, pipe boots (new vs reuse) (flashing basics).
  • Ventilation — ridge vent LF, box vents, intake soffit work (ventilation).
  • Warranties — manufacturer registration vs labor-only years (warranty voids).
  • Timeline, payment schedule, permit responsibility.

Red flags that should stop the signing pen

  • Door-to-door storm chaser with same-day insurance pressure — see hail inspection process.
  • One-line total with no squares or materials list.
  • Cash-only large deposits before materials are on site.
  • No license/insurance proof — verify at vet local contractors.
  • “We’ll use whatever underlayment is on the truck” without naming product type.
  • Verbal-only change orders for decking once tear-off starts.

Compare three bids on the same spreadsheet

Make columns: squares, tear-off, decking $/sheet, ice & water, synthetic/felt, shingle brand/line, ridge vent, drip edge, boots, permit, warranty years, start window. Force each contractor to fill blanks. The middle bid often wins once the cheap bid adds missing decking.

Unit prices worth knowing

You do not need contractor pricing software, but you should recognize when a decking allowance is fantasy-low or a dump fee is missing entirely. Ask: “If you replace 10 sheets of decking, what do I pay per sheet installed?” Write the answer on the bid. Same for chimney step flashing and skylight re-flash kits.

Insurance jobs

Ask for the claim line-item sheet. Your deductible and depreciation rules matter. Do not let anyone “waive your deductible” — that can be illegal and is a fraud red flag. Document pre-existing issues with photos before tarp work. Align contractor scope to adjuster lines, then negotiate supplements with evidence — not vibes.

Payment schedules that protect both sides

Reasonable patterns often look like a modest deposit, materials draw when bundles land, progress draw after dry-in, and retainage until final walkthrough and warranty registration. Huge up-front cash for a crew you met yesterday is how homeowners fund someone else’s next job — not yours.

After you pick a contractor

Walk the property together: trees, AC lines, satellite dishes, future solar. If solar is coming, sequence roof first — roof before solar. Materials you may self-supply: roofing product finder.

Frequently asked questions

How many quotes should I get?

Three is standard — same scope spreadsheet for each.

Is the cheapest bid always worse?

Not always, but missing decking and underlayment lines usually mean change orders later.

Should I pay 50% up front?

Large deposits before materials arrive are a risk — staged payments tied to milestones are safer.
