Metal Roofing in Campbell Way, Washington — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum contains no iron, so it physically cannot rust. Instead, it forms a thin oxide layer that actually protects the metal underneath — and when that layer gets scratched, it self-heals. In Kitsap County, where you're averaging about 1280 mm of annual rainfall, that passive protection matters more than most places. We coat both sides of every panel with Alunar 70% PVDF fluorocarbon finish, warranted 30 years against chalking and fading. Steel roofs require constant vigilance; aluminum just sits there working.

The four-way interlocking panels lock water out mechanically while the smooth surface sheds snow faster than textured asphalt. You'll see about 33 cm of snow per year here, plus roughly 21 freeze-thaw cycles that crack and curl traditional shingles. Metal panels expand and contract uniformly without creating the micro-gaps where ice dams start. Snow guards are available if you need them, and the lightweight aluminum (Shake profile at 0.58 lb/sq ft) means snow load never stresses your structure the way concrete or clay tile would.

Your region averages gusts up to 101 km/h, and our panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. The four-way interlocking design locks each panel to its neighbors on all sides — there's no single nail or fastener that can fail and lift a corner. That mechanical grip is why we've installed these roofs from coastal salt-air homes to an Antarctic research station. Your local gusts fall well within the warranty range.

These panels carry a UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. That kind of durability sometimes qualifies homeowners for insurance discounts; contact your carrier with the UL rating and ICC-ES ESR-1790 evaluation report. Asphalt shingles fail at much smaller impacts. Many insurers recognize that Class 4 metal roofs simply don't generate claims the way traditional roofs do in severe weather.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner — it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, the next owner inherits a 50-year term from completion. We've been manufacturing these panels since 1998 in Delta, BC; homes installed in our first year are still going strong. The 30-year PVDF coating warranty alone outlasts three asphalt roof cycles in Kitsap's wet climate.

No structural work required. The Mediterranean Tile profile installs at just 0.59 lb/sq ft — about 96% lighter than real concrete or clay tile — so it goes over most existing roofs without reinforcement. Compare that to traditional tile, which demands roof reconstruction and foundation stress. In a region with 21 annual freeze-thaw cycles, that matters: lighter loads mean less structural fatigue. Your framing handles the weight of a few adults standing on your roof; that's all you're adding.

Installation timeline depends on roof size and complexity, but we can install directly over your existing asphalt shingles in most cases — no costly tear-off. That means less disruption, faster completion, and no landfill fees. Our crew, Interlock Metal Roofing (PNW) Inc., has served this region since 1997 and knows every roofline in Kitsap County. We handle the permit process and coordinate around your schedule. Call for a site visit and we'll give you a firm timeline.

Your area gets about 2931 hours of sunshine per year, so reflective properties matter. energy-efficient Interlock colors feature thermal emissivity of 0.84 and solar reflectance up to 0.55 in Aged Copper Penny — that means the roof bounces heat away rather than absorbing it like asphalt does. The Cool Roof Rating Council rates these coatings. In summer, that reflectance reduces air-conditioning load; in Kitsap's mild winters (mean 11.3°C), you're not sacrificing passive solar gain. Real energy savings, measured by the people who set national efficiency standards.

Far less than asphalt or cedar. Asphalt shingles crack, curl, and lose granules in the 21 freeze-thaw cycles you experience annually. Cedar splits, rots, and needs regular treatment or replacement. Interlock panels shed water, don't absorb it, and the Alunar coating resists the algae and mold that thrive in Pacific Northwest moisture. CALGreen-verified for reduced maintenance. You're looking at occasional gutter cleaning and maybe checking fasteners after extreme weather — that's it. No re-shingling, no wood treatment, no seal coating every five years.

Yes. Aluminum is approximately 95% recyclable; at end of life, your panels go back to the mill, not a landfill. Asphalt shingles tear off, go to the dump, and stay there for centuries. With 1280 mm of annual rain and 33 cm of snow, Kitsap's homes generate significant roofing waste over time. Choosing metal breaks that cycle. These panels have been manufactured since 1998 — that's 25 years of real-world proof that recycled aluminum content and post-consumer reclamation make metal roofing one of the few roofing choices that doesn't create permanent waste.
