Metal Roofing in Aberdeen Gardens, Washington — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow and ice better than asphalt because the smooth, slick surface prevents buildup—critical here where you get about 60 cm of snow annually and experience roughly 38 freeze-thaw days per year. Interlock's four-way interlocking panels keep water sealed at the seams; add snow guards if you want snow to stay put for insulation value. The lightweight aluminum (Shake profile at 0.58 lb/sq ft) means no structural load concerns even after wet snow accumulates, and the panels won't crack or curl like asphalt or wood shakes do under repeated freeze-thaw stress.

Interlock roofing is made from 3105-H24 and 3003-H24 aluminum alloy—aluminum contains no iron, so it cannot rust, period. Instead, aluminum naturally forms a thin oxide layer that actually heals itself when scratched or abraded. In Grays Harbor County's wet climate (2305 mm rain per year), this self-protecting chemistry outperforms steel, which requires paint or coating to stay corrosion-free. Add the Alunar 70% PVDF fluorocarbon finish on both panel sides, and your roof resists the salt-air conditions that corrode other metals—the coating itself carries a 30-year warranty against chalking and fading.

Asphalt typically costs less upfront but needs replacement every 15–25 years; Interlock carries a lifetime limited, non-prorated material warranty for the original owner. Over a 50-year span, you'll buy asphalt two or three times while you own your metal roof once. Factor in that Interlock installs at roughly 0.41–0.59 lb/sq ft—so light it needs no structural reinforcement—plus the current promotion (no payments, no interest until Spring 2027, or 10% off installation), and the math shifts. Recycling aluminum at end-of-life also avoids asphalt landfill costs, making the true cost-per-year lower than most homeowners expect.

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, with no dollar caps and no annual degradation. When you sell, the warranty transfers once to the next owner, who gets 50 years of coverage from the roof's completion date. That transferable term makes your roof a resale asset. Manufactured since 1998 in Delta, BC, and installed from coastal salt-air homes to an Antarctic research station, Interlock panels routinely outlast the buildings they're mounted on.

Metal roofs need far less maintenance than asphalt, cedar, or tile. No moss removal, no missing shingle repairs, no seasonal inspection rituals—asphalt degrades from UV and thermal cycling; tile cracks and traps debris; wood shakes rot in the Pacific Northwest's 2305 mm of annual rainfall. Interlock's aluminum and Alunar coating are CALGreen-verified for reduced maintenance. Occasional gutter cleaning and a visual inspection every few years is all you need. The solid deck and underlayment make it as quiet as an asphalt roof in rain, so no noise-related regret either. That's years of your life back.

Interlock metal roofing is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. In Aberdeen Gardens, typical daily-max winds run around 15 km/h with gusts to about 106 km/h—well within the roof's rated envelope. The four-way interlocking panel design locks each piece to its neighbors, so wind pressure that lifts one corner encounters mechanical resistance across the entire roof. This is why Interlock qualifies for ICC-ES ESR-1790 code approval under IBC/IRC standards. You get documented wind-rating strength, not marketing language.

No. Interlock's Mediterranean Tile profile, the heaviest style, weighs only 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so it installs over most existing roofs without any reinforcement. Even the Slate profile comes in around 0.41 lb/sq ft. Compare that to the structural load of asphalt shingles (which also need no reinforcement) and realize you can reroof over your old shingles in a single day with zero framing concerns. Lightweight aluminum lets you avoid the cost and disruption of structural upgrades, and it qualifies under building code ESR-1790 because load capacity is simply not an issue here.

With about 2305 mm of rain per year, water management is non-negotiable. Interlock's four-way interlocking panels create a unified, sealed membrane where each piece locks to the next—water sheds downslope and can't pool at seams. The solid deck beneath and underlayment form a layered defense: if any water breaches the panel interlocks (unlikely), it's caught and drained. Installation over your existing roof adds an extra barrier. Class A fire-rated aluminum panels (non-combustible per ICC-ES ESR-1790) don't absorb water like asphalt, and the material won't degrade from prolonged wet exposure. Your roof stays dry year-round.

Aluminum is roughly 95% recyclable at end-of-life, and Interlock panels contain recycled content. Asphalt shingles, by contrast, end up in landfills by the millions of tons annually—there's no economical recycling stream. Over a 50-year period, you'd send two or three asphalt roofs to the dump while your Interlock roof gets melted down and reformed into new products. The manufacturing process in Delta, BC, has been running since 1998 with minimal waste. If you care about breaking the tear-off cycle and reducing your home's landfill footprint, metal aluminum is the measurable choice.

Local service means faster response times, familiarity with code inspectors, and crews who've installed hundreds of roofs in conditions identical to yours. Call them to schedule a free estimate and walk through profile options (Slate, Cedar Shingle, Shake, Mediterranean Tile, or Standing Seam) on your home.

Yes. Aberdeen Gardens averages about 60 cm of snow, 2305 mm of rain, roughly 38 freeze–thaw days a year, with peak wind gusts near 106 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
