Do I need a permit for roof replacement in
Covington, Washington?

You're replacing the roof on a 1,800-square-foot ranch home (roughly 18 squares) in the rural unincorporated area near Covington, but the city's jurisdiction applies if your address falls within city limits. The home has one existing layer of aging asphalt shingles in good repair on the deck; you're keeping the same material and grade (e.g., 25-year architectural shingle). A permit is still required because you're performing a full tear-off to the deck and new underlayment. The City of Covington Building Department fees will be approximately $200–$280 (at $12/100 sq.ft. plus $50 base). Submit the application in person with a site photo, roof plan showing total square footage and slope, and the shingle product spec sheet. Specify 'synthetic underlayment, ice-and-water shield extended 24 inches from eave per IRC R905.2.8.2.' Expect a 3–5 day turnaround if complete. The building inspector will schedule a deck inspection (to verify sound sheathing and proper nailing pattern — 6 nails per shingle in this climate, with ring-shank or roofing nails), then a final inspection once shingles and flashing are set. Total timeline: 1 week to permit issuance plus 2–3 weeks for the roofing crew (weather-dependent) plus 2–3 days for inspections. Total permit and inspection cost: $200–$280 plus contractor labor and materials (typically $8,000–$15,000 for this square footage and grade in the Covington area).

Your 1970s home in downtown Covington has a cathedral ceiling and a vaulted master bedroom. You've decided to upgrade to a metal standing-seam roof (better longevity, better appearance in the Puget Sound region) and are replacing one existing shingle layer with the metal system. This material change (asphalt to metal) triggers a permit requirement, and the structural evaluation is mandatory because metal roofing adds 1.5–2 lbs/sq.ft., and older trusses (1970s) have lower design loads than modern builds. The City of Covington Building Department will require a one-page structural certification from a professional engineer or from the metal roofing contractor, stating existing framing is adequate for the additional load (or noting that lateral bracing will be added). Permit fee will be $250–$380 (at $12–$18 per 100 sq.ft. for material change, plus $50 plan-review surcharge). The cathedral ceiling and vaulted design also mean the secondary water barrier (ice-and-water shield or self-adhering underlayment) must extend completely across the interior slope to manage wintertime vapor drive and condensation risk; the inspector will look for this detail on the roof plan. Submit the application with: (1) roof plan showing total square footage, slope, cathedral/vault areas highlighted; (2) metal roofing product spec (e.g., 24-gauge Kynar 500 standing seam, 0.018-inch aluminum); (3) structural certification from the roofing supplier or engineer; (4) underlayment detail diagram showing ice-shield coverage on interior slopes. Processing time: 7–10 business days due to plan review complexity. The inspector will do a framing inspection (to verify roof load path and bracing) before the metal is installed, then a final inspection. Total project cost: permit $250–$380 plus metal roofing installation $12,000–$20,000 for this square footage and the standing-seam system.

A winter windstorm damaged a section of your roof on a 1990s colonial in Covington, and the shingles on the north slope are torn and missing. The damage is confined to roughly 8 squares (8% of a 100-square roof), and you're having a local roofer patch with the same grade and color shingles, without tearing off the existing roof. This repair falls under the 25%-of-roof exemption (IRC R905.3.2), so no permit is required. However, confirm the exact scope with the roofer: if the work includes stripping the damaged section down to the deck and replacing sheathing (e.g., if water damage extends to the wood), that would cross into a permit-requiring repair. Assuming the sheathing is sound and the roofer is overlaying new shingles and flashing only, this is a straightforward repair that doesn't require a city permit. The roofer should provide you a written quote specifying 'overlay of wind-damaged shingles, existing decking retained, same material and grade.' If the patch area is less than 50 linear feet of ridge and the underlying deck is not exposed, no inspection is needed. However, document the repair in writing and keep photos for your insurance claim and future resale disclosure purposes. Typical cost: $800–$2,000 in labor and materials, with no permit fees. Note: if the damage or repair extends to the gutter line or soffit (e.g., wind damage also tore the fascia), the scope may expand — gutter or soffit replacement is still exempt, but make sure the roofer isn't de facto rebuilding the roof-to-wall junction, which would trigger a permit.
