Roof replacement permit in the Seattle area (2026):
city by city
DO YOU NEED A PERMIT TO REPLACE A ROOF IN WASHINGTON?
Rules differ across the Seattle area. Kent requires a permit to add, repair or remove any roof. Seattle and Tacoma generally don't for a like-for-like replacement on a house, and Bellevue doesn't unless sheathing work goes beyond five sheets or an overlay adds more than 5% to the roof's weight. Renton requires one if sheathing is replaced. Always confirm with your city before work starts.
Roof permit rules by city
| City | Like-for-like re-roof on a house | When a permit is needed |
|---|---|---|
| Seattle | Usually no permit | Changes to the building envelope other than adding or replacing insulation |
| Kent | Permit required | Adding, repairing or removing any roof |
| Bellevue | Usually no permit | Sheathing work beyond five 4 × 8 ft sheets, or an overlay that adds more than 5% to the roof's weight |
| Renton | Ask the city | Replacing sheathing (issued over the counter); structural roof changes need a building permit |
| Tacoma | No permit for the same roofing type | Adding a layer over the old roof, or changing the roofline |
| Auburn | Ask the city | Its FAQ says you "may need a permit" for reroofing |
| Federal Way | Ask the city | The city pages we checked don't address roofing |
City details
Seattle
SDCI says a permit is not required for re-roofing one- and two-family homes and townhouses if no changes are made to the building envelope other than adding or replacing insulation, as long as the insulation is as good or better. For prices, see roof replacement cost in Seattle.
Kent
Kent lists "adding, repairing, or removing any roofs" among work that needs a residential building permit. A residential re-roof (one or two units) is a Minor Work Permit, applied for through the city's permitting portal, and Kent says it typically processes these within 2–3 business days. The scope must state the materials being removed, the underlayment and the new materials, plus the contractor's Washington license number if a contractor does the work. Kent adds a 2.65% processing fee to card payments. For manufactured homes, Kent says roof and re-roof changes go through the Department of Labor & Industries.
Bellevue
For an overlay, Bellevue says no building permit is required unless the new material adds more than 5% to the roof's total weight, and there are no energy code requirements for a roof recover. For a replacement, no permit is needed if sheathing work is limited to five 4 × 8 ft sheets. If the roof cavity is exposed, the city says it must be insulated to full depth. Questions go to Building Review at 425-452-4121.
Renton
Renton says a permit is required to replace sheathing on a single-family home, issued over the counter, and that structural changes to roof framing or heavier roofing need a building permit with plan review. Re-roof permits can be applied for online through the city's Civic Access portal. Its FAQ doesn't clearly cover replacing only the roof covering on a house, so ask the permit desk at 425-430-7215.
Tacoma
Tacoma says no permit is needed to remove and replace old roofing with the same roofing type. Adding a layer over existing roofing requires a pre-roof inspection and a permit, and changing a roofline also requires a permit.
Auburn and Federal Way
Auburn's FAQ lists reroofing among projects that may need a permit; call its permit center at 253-931-3090 (option 2). Federal Way's permit pages we checked don't mention roofing; call its Permit Center at 253-835-2607.

Who pulls the permit?
- Ask your roofer whether a permit is needed in your city and whether the fee is in the quote. Our guide on how to read a roofing estimate covers the permit line.
- Kent asks for the contractor's Washington license number on the application. Look the roofer up on L&I's Verify a Contractor tool before you sign.
- For jobs of $1,000 or more on a home, the contractor must give you a written disclosure statement before work starts (RCW 18.27.114).
- Thinking of a new roof over the old one? Several cities treat an overlay differently; see roof overlay vs tear-off.
