Thinking about replacing your roof in Newcastle and unsure if you need a permit? You are not alone. A reroof is a big investment, and getting the permit and inspection piece right helps you avoid delays, fines, and resale headaches. In this guide, you will learn exactly when a permit is required, what inspections to expect, and how this may affect a future sale. Let’s dive in.
Do you need a permit in Newcastle?
For one- and two-family homes, “like-for-like” reroofing that does not remove or replace roof sheathing is typically exempt from a building permit. The City explains this exemption and the situations that do require a permit on its permits page. You can review the City’s guidance on re-roofs and exemptions on the Newcastle permit portal and Building Division pages for details and contacts for clarification.

Permit-exempt like-for-like reroofs
If your project replaces roofing material in-kind, stays within the same system, and does not remove or replace sheathing on a one- or two-family dwelling, it is generally exempt. Roof recover projects can still raise technical issues like weight, ventilation, or energy code, so confirm your scope with the City if you are unsure. When in doubt, ask the permit coordinator or apply for a permit to be safe.
When a permit is required
You will need a building permit if your project removes or replaces sheathing, alters the roof structure, changes to a materially different roofing system, or involves multiple existing layers. Permitted projects require inspections before covering work. The City’s construction administrative code and permit pages outline these triggers and requirements. Review the City’s code and fee section here: Newcastle Municipal Code Chapter 15.05.
How to apply for a permit
Newcastle accepts building permit applications in person at City Hall or online via MyBuildingPermit.com for many permit types. The permits page explains submittal steps, contacts, and what to include with your application. If your reroof touches sheathing, plan to include manufacturer installation instructions and any drawings needed to show scope.

Fees and timing
Newcastle uses a valuation-based fee schedule in NMC 15.05.109. Plan review fees and reinspection or special inspections are additional as listed in the code. Because costs vary by project size and materials, use the City’s fee table with the ICC valuation method or ask the permit coordinator for an estimate. See the fee table reference: NMC 15.05.109.
The City does not guarantee a fixed review time. Turnaround depends on scope and workload. For current timeframes, check with the permit coordinator or MyBuildingPermit.
Permit expiration
City permits expire two years from issuance if work is not completed and finalized. If you need more time, request an extension per City policy. See the City’s permit information: Newcastle permits.
Required inspections
Permitted reroofs typically include a roof sheathing inspection before any covering goes on and a final inspection at completion. The code requires that work remain visible and accessible until approved. Inspectors may ask to review the manufacturer’s installation instructions on site.
- Inspection rules and reinspection fees: NMC Chapter 15.05
What inspectors commonly check:
- Condition and attachment of sheathing and framing where exposed.
- Proper underlayment, drip edge, and flashing at valleys, chimneys, and penetrations.
- Ventilation and any Washington State Energy Code requirements when sheathing or insulation is exposed.
- Compliance with manufacturer instructions and proper disposal practices.
Covering work before inspection can lead to rework, reinspection fees, or delays in final approval. Keep required elements open until approved.
Asbestos and safety rules in King County
Before you start, confirm asbestos requirements. Washington L&I requires a good-faith asbestos inspection before renovation work that could disturb suspect materials, and certifications or notifications may apply depending on the findings. The Puget Sound Clean Air Agency sets regional survey and notification rules for King County projects.
- L&I asbestos guidance: Washington L&I
- Regional rules and homeowner guidance: PSCAA Homeowner Renovation and PSCAA Asbestos Overview
For owner-occupied single-family homes, PSCAA allows limited homeowner surveys under specific conditions. If asbestos is present above thresholds, file the required notifications and use certified abatement.
Energy code impacts when sheathing is exposed
If your reroof exposes sheathing or insulation, parts of the Washington State Energy Code can apply to the altered roof assembly. That may affect insulation levels and materials. Newcastle has adopted the state-amended 2021 construction codes, which guide design loads and energy requirements.

Hiring and verifying a contractor
Verify your roofer’s registration, bond, insurance, and workers’ compensation coverage using Washington L&I’s Hire Smart guidance and verification tools. Newcastle also requires hired contractors to have a City business license, noted by the City as a $50 annual charge. Always request proof of active L&I registration and confirm the local license requirement.

- For older homes or legacy roof systems, follow PSCAA’s guidance for surveys and notifications. Start with PSCAA Homeowner Renovation.
- Verify your contractor

- Apply for the permit if required
- Submit at City Hall or through MyBuildingPermit. Expect a roof sheathing inspection before covering and a final inspection. See Newcastle permits.

Buying or selling soon?
Permitted, inspected roof work helps buyers and appraisers trust the condition of the home. Unpermitted work can invite stop-work orders, reinspection fees, or required corrections, and it may complicate future real estate transactions. Review the City’s enforcement and inspection provisions in NMC Chapter 15.05 and keep all final approvals and warranty paperwork for your records.
