Certified for lead-safe renovation: re-roofing older Washington homes
Interlock Metal Roofing (PNW) Inc. is certified by the Washington State Department of Commerce as a lead-based paint renovation (RRP) firm, certification R7896, current through July 23, 2030. Washington runs its own EPA-authorized program under chapter 365-230 WAC, so renovation firms working on pre-1978 Washington homes are certified by the state rather than by EPA. In Oregon, the company holds the CCB Lead-Based Paint Renovation license (CCB #130826).

Questions about Washington certification: Department of Commerce Lead-Based Paint Program
Why a roofing job can be a lead job
Lead-based paint was banned for residential use in 1978. Seattle's older neighborhoods, Bellingham, and the older towns of Snohomish, Skagit and Island counties are full of homes from before that date. On those houses the roofing itself is rarely painted — the wood around it often is. A re-roof routinely disturbs:
- Fascia and rake boards — painted wood that is often removed or replaced at the roof edge.
- Soffits and eave trim — disturbed when drip edge, gutters or ventilation change.
- Dormer siding and trim — cut back where new roofing meets the dormer walls.
- Painted trim at chimneys and sidewalls — disturbed when step and counter flashing is replaced.
Washington's renovation rules cover paid work that disturbs painted surfaces on homes built before 1978 and on child-occupied facilities, beyond the minor-repair exemption. The Department of Commerce certifies renovation firms and individual renovators under chapter 365-230 WAC.
What lead-safe work looks like on your roof
Washington's program is EPA-authorized, which means it must be at least as protective as the federal rule. On a covered exterior job, that baseline is:
Before work starts
You receive EPA's Renovate Right pamphlet no more than 60 days before work begins, and warning signs go up around the work area (40 CFR 745.84 and 745.85).
A certified renovator on every job
A certified renovator is assigned to each covered job, and everyone disturbing paint is a certified renovator or trained by one (40 CFR 745.89(d)).
Containment
Doors and windows within 20 feet are closed, and the ground is covered with disposable plastic sheeting extending 10 feet beyond the work area — further if debris could travel farther (40 CFR 745.85(a)(2)(ii)).
Prohibited practices
No open-flame burning or torching of painted surfaces; no high-speed sanding or grinding without a shroud and HEPA vacuum; heat guns only below 1,100 °F (40 CFR 745.85(a)(3)).
Cleanup and records
Debris is contained and removed, a certified renovator visually checks the work area and the ground before the signs come down, and records are kept for three years (40 CFR 745.85(b), 745.86).
Which credential applies where
Washington and Oregon both run their own EPA-authorized programs, so each state's credential — not an EPA certificate — is the one that applies there.
Lead-safe roofing questions, answered
Does Washington's lead rule apply to a roof replacement?
It can. If the house was built before 1978 and the work disturbs painted surfaces beyond the minor-repair exemption — fascia, rake trim, soffits, dormer siding — the renovation rules apply, and the firm doing it must be certified by the Department of Commerce.
Is an EPA lead certificate enough in Washington?
No. Washington administers its own EPA-authorized program, so renovation firms are certified by the Department of Commerce. Contractors who hold EPA or other-state certification must register with Commerce. Ours is Washington RRP firm certification R7896.
How can I verify your Washington certification?
The Department of Commerce Lead-Based Paint Program can confirm firm certification R7896; its contact form and phone line (360-586-5323) are on the Commerce RRP page linked below.
What about work in Oregon?
Oregon also runs its own program. For Oregon jobs, the company holds the Construction Contractors Board's Lead-Based Paint Renovation license under CCB #130826, which shows as Active on the CCB Lead Safe Contractor search.
