Metal Roofing in Beverly Beach, Washington — Lifetime Interlock® Aluminum Shingles Installed Locally

Interlock's four-way interlocking aluminum panels shed snow reliably because aluminum doesn't expand and contract the way asphalt or wood does—it's dimensionally stable through Beverly Beach's roughly 31 freeze-thaw days per year. The smooth, hard surface prevents ice from bonding as strongly as shingles do. With about 37 cm of annual snow, a pitched metal roof with optional snow guards keeps ice dams from forming along gutters. The lightweight construction (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed, even when snow accumulates.

No. Interlock panels are four-way interlocking—water cannot run horizontally between seams. Beverly Beach receives about 1148 mm of rain annually, and the overlapping design directs all water downward and out through gutters. The panels are installed over a solid deck with underlayment, creating a complete water barrier. The interlocking geometry and installation method comply with ICC-ES ESR-1790 (reissued 2025) for IBC/IRC code requirements, which includes water-shedding performance standards.

Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), which contains no iron and therefore cannot rust—period. When aluminum is scratched, its oxide layer self-heals, protecting the underlying metal. In salt-air coastal environments, the Alunar 70% PVDF fluorocarbon finish (applied to both sides) adds a 30-year coating warranty against chalking and fading. This two-layer protection strategy matters in Beverly Beach's marine climate where wind gusts reach 112 km/h and salt spray is common.

Yes. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Beverly Beach's typical gusts reach 112 km/h, well within that tolerance. The four-way interlocking design locks each panel to its neighbors, distributing wind load across the entire roof system rather than concentrating stress on fasteners. The Guardian warranty backs this performance, and the installation method (compliant with ESR-1790) ensures the panels stay secure during the strong wind events that occur here.

energy-efficient Interlock colors reflect solar heat rather than absorbing it the way asphalt does. Rated colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55, which reduces the heat load transmitted into your attic. Beverly Beach receives about 2898 sunshine hours annually, so summer heat gain matters. Cool Roof Rating Council certification confirms the reflectance performance. Lower attic temperatures reduce air-conditioning demand, especially during the warmer months when the sun is strongest.

Interlock achieves UL 2218 Class 4 impact rating—the highest available. The warranty covers perforation from hailstones up to 1.5 inches, which is rare but possible in severe storms. Several insurers recognize this non-combustible, impact-resistant construction and offer discounts on homeowners' policies. The lightweight, durable aluminum construction combined with Class A fire rating (non-combustible) makes the roof attractive to underwriters. Contact your agent with the UL 2218 Class 4 specification and ESR-1790 code report to discuss potential premium reductions.

No structural reinforcement is needed. Interlock's Mediterranean Tile profile weighs about 0.59 lb/sq ft—roughly 96% lighter than genuine concrete or clay tile—and can install directly over most existing roofs. The Shake profile weighs 0.58 lb/sq ft, and the Slate just 0.41 lb/sq ft. This lightweight design means your existing framing already supports it. The reduction in structural demand is especially valuable if you're replacing heavier materials or live in a climate with snow load, like Beverly Beach's 37 cm average annual snowfall.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable to the next owner, who receives 50 years of coverage from the completion date. This dual-tier protection adds significant value at resale. Combined with the 30-year coating warranty on the Alunar finish, you have comprehensive, long-term protection against the elements Beverly Beach experiences year-round: 1148 mm of rain, 31 freeze-thaw cycles, and salt-laden wind.
