§ Seattle fast facts

QUICK ANSWERS.

Do I need a permit to reroof a house in Seattle?

Yes. Seattle requires a building permit from SDCI for full tear-off reroofs and any job that alters more than 25% of the roof surface. Permit fees run $185–$310 for typical residential work. Simple recover-over-existing may qualify for an exemption — confirm with SDCI before pulling the permit.

§ Built for Seattle

LOCAL FACTS.

SEATTLE UNION JOURNEYMAN ROOFER WAGE RATE (2024).

Approximately $48–$54/hr base wage for union journeyman roofers in the Seattle metro under WSBCTC agreements, before fringes and payroll burden.

SDCI RESIDENTIAL REROOF PERMIT FEE (SEATTLE).

$185–$310 for a standard residential reroof permit through the Seattle Department of Construction and Inspections, based on project valuation; required for most full tear-off and recover projects.

WASHINGTON STATE ENERGY CODE REROOFING INSULATION REQUIREMENT.

WAC 51-11C requires minimum R-38 attic insulation when a reroof disturbs more than 50% of the existing roof deck — a common trigger on full tear-offs in Seattle that must be included in the estimate scope.

SEATTLE ANNUAL RAINFALL AND PEAK ROOFING DEMAND.

Seattle averages 37–38 inches of rain annually across roughly 152 rainy days. Emergency repair calls and reroof inquiries peak October through December as fall storms expose failing systems.

§ Why roofing pros in Seattle use Estimate.Pro

THE BID ENGINE.

## Roofing in Seattle Moves at Its Own Pace Seattle averages 152 rainy days a year. That means every homeowner with a failing roof wants a bid yesterday, and every delay costs you the job. You need an estimate in the customer's inbox before a competitor shows up. Estimate.Pro takes you from walkthrough to sendable bid in 8 minutes — a median backed by real job data, not a marketing number. --- ## What Makes Seattle Roofing Estimates Different **Steep-slope math matters here.** Seattle's Craftsman bungalows and older two-story colonials routinely run 8/12 to 12/12 pitches. The app applies pitch multipliers automatically so your square footage never understates labor. **Moss and algae remediation is a line item, not an afterthought.** The Pacific Northwest climate means moss treatment — zinc strips, biocide wash, or mechanical removal — is part of nearly every reroof quote. Estimate.Pro lets you build that into your saved material cost workspace so it never gets left off a bid again. **Washington State energy code adds complexity.** WAC 51-11C (the Washington State Energy Code) requires minimum R-38 attic insulation on reroofs that disturb more than 50% of the roof deck. If you're tearing off to the sheathing, that code triggers. Your estimate should reflect it. The app lets you add insulation scope as a conditional line item tied to tear-off depth. **Permit fees in Seattle are real money.** A standard residential reroof permit through the Seattle Department of Construction and Inspections (SDCI) runs $185–$310 depending on valuation. That's a line item, not overhead. Build it in before you submit. --- ## How the Walkthrough Works Open the app on-site. Walk the perimeter. Use AR measurement on supported devices — ONNX-assisted live AR — to capture eave lengths, ridge lines, and hip returns. Camera or photo measurements are flagged as estimates so you know what to verify on the roof. The app assembles your scope of work from what you captured, not from memory. No more bidding from a sketch on the back of a business card. --- ## Calculators Built for Roofers - **Squares calculator** — converts measured roof surface to roofing squares with pitch factor applied - **Waste factor adjuster** — hip-and-valley roofs in Seattle's older neighborhoods waste more material; set your factor per job - **Underlayment selector** — synthetic vs. felt, with per-square pricing pulled from your saved workspace - **Drip edge and flashing estimator** — linear footage auto-calculated from eave and rake measurements - **Moss treatment line item** — unit-priced per square or per linear foot of ridge cap - **Insulation upgrade trigger** — add R-38 scope when tear-off exceeds 50% per WAC 51-11C --- ## Pricing That Matches How You Work Estimate.Pro is free to start — no credit card, no time limit. If you're a solo operator running 10–15 roofs a month, the Pro plan at $39/seat/month covers full estimating with 0% platform fees on Elite, or 3% on Free tier Stripe Connect invoicing. Crews with multiple estimators can go flat at $399/month for the whole team. You keep the margin. The platform doesn't take a cut of your job revenue on Pro+. --- ## Built for the Seattle Roofer Seattle's roofing market is competitive. You're quoting against regional contractors and national franchises. The difference between winning and losing a reroof often comes down to who gets the estimate in front of the homeowner first, and whether the number holds up when the project manager walks the job. Estimate.Pro gives you a bid that's fast, local, and defensible — built from a real walkthrough with real measurements, not a per-square rule of thumb. Start free. No card required.
