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

Yes — metal roofing sheds snow and ice far better than asphalt. Lebam averages about 49 cm of snow annually with roughly 34 freeze-thaw cycles per year, which is exactly where metal roofs outperform. The four-way interlocking aluminum panels are engineered to shed water and snow effectively, and because aluminum is so light (Shake profile at 0.58 lb/sq ft), you never exceed snow-load limits even with dense accumulation. Ice dams that trap water on asphalt simply don't form the same way on metal. Snow guards are available if you want to control sliding on steep pitches.

Aluminum cannot rust — that's the core advantage over steel. Our panels are roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), which contains no iron. When the bare metal gets scratched, the oxide layer self-heals automatically, so even coastal homes and areas with salt-laden air stay protected. Lebam's 1578 mm of annual rainfall won't corrode aluminum the way it corrodes steel or promotes rot in asphalt. The Alunar 70% PVDF fluorocarbon finish on both sides of every panel adds a 30-year warranty against chalking and fading, giving you dual protection in this damp Pacific County climate.

Completely. Local wind gusts regularly reach 103 km/h, and the Interlock roof is warranted to resist sustained winds up to 120 mph (193 km/h) when installed to spec. The four-way interlocking aluminum panels lock together mechanically — each panel fastens to the deck and interlocks with its neighbors, so wind can't peel a single panel loose. This system performs far better than nail-strip asphalt shingles in high-wind zones. The ICC-ES evaluation report ESR-1790 covers this design for IBC/IRC compliance, and the Guardian Warranty backs that 120 mph performance guarantee for the life of the original owner.

Interlock carries a UL 2218 Class 4 impact rating — the highest available — and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. This rating can qualify you for homeowner insurance discounts in Washington, since insurers recognize that aluminum roofs survive hail events that dent or puncture asphalt shingles. Many carriers offer 10–20% premium reductions for Class 4 impact-rated roofs. While Lebam's weather data doesn't suggest frequent severe hail, the Class 4 rating means if a hail event does occur, your roof walks away unharmed and your insurer may lower your rates going forward.

No structural reinforcement is needed. The Shake profile installs at just 0.58 lb/sq ft — making it about 96% lighter than concrete or clay tile. This extreme lightness means most homes in Lebam can accept a metal roof directly over existing asphalt shingles without adding support beams or trusses. Compare that to traditional tile, and you're avoiding tens of thousands in structural work. The four-way interlocking aluminum design distributes this minimal load evenly across the deck, so your existing framing handles it with ease. This is why metal roofing also works as a retrofit on older homes that were never built to support heavy tile.

Over 50 years, yes — it's the last roof you buy. Asphalt requires replacement every 15–20 years in Lebam's wet, freeze-thaw climate (34 annual freeze-thaw cycles accelerate deterioration). Aluminum installs once and delivers a lifetime limited, non-prorated material warranty on the original owner — covering rusting, rotting, splitting, cracking, curling, and impact loss — plus a one-time transfer that gives the next owner 50 years from completion. No tear-off to landfill, no labor costs every two decades. When you factor in avoided replacement labor and disposal, a metal roof cost-justifies itself in 15–20 years. Current financing includes no payments and no interest until Spring 2027, or 10% off installation.

Aluminum and its four-way interlocking design excel in wet climates. The 1578 mm of annual rainfall in Lebam — more than most U.S. regions — won't pool or leak because water simply runs off the smooth, non-absorbent metal surface. Each panel interlocks to its neighbor and fastens to solid decking, so there's no gap for water to infiltrate like there can be with asphalt shingles, especially after 10–15 years of weathering. The aluminum doesn't absorb moisture, so the wood deck beneath stays dry and protected from rot. Combined with proper underlayment and flashing, this design stops water every time — no asphalt-style granule loss, no curling edges letting water creep underneath.

The Guardian Warranty is a lifetime limited, non-prorated material warranty on the original homeowner — that means no reduction in coverage year-over-year. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance for life. The warranty is one-time transferable to the next owner, who receives 50 years of protection from the roof completion date. This addresses the typical Lebam homeowner's concern: you install this roof, live in your home through decades of 49 cm of snow, 1578 mm of rain, and 34 freeze-thaw cycles per year, and the roof stays covered. When you sell, the buyer gets a reassuring 50-year backstop, which significantly improves your home's appeal and resale value.

Virtually none. Aluminum doesn't rot like wood, doesn't split, and can't rust. There's no periodic sealing, no granule replacement, and no moss-and-algae-fighting treatments to reapply every few years like asphalt requires in Lebam's 2757 annual sunshine hours and damp conditions. The Alunar 70% PVDF finish is warranted 30 years against chalking and fading (ASTM D4214 / D2244), so color stays true through decades of Pacific County rain and UV. Most owners simply rinse debris off once or twice annually. CALGreen-verified data confirms the maintenance reduction compared to traditional roofs. This saves you hundreds of dollars over the roof's life and countless weekends on a ladder or phone with contractors.

Yes. The extraordinary light weight of aluminum — even the heaviest Tile profile at about 0.59 lb/sq ft — means installation over existing asphalt is permitted on most residential structures. Your contractor removes only gutters and flashings, installs a solid deck where needed and underlayment, then fastens the interlocking panels directly to the old roof. This avoids tear-off labor, disposal costs, and re-roofing delays. Interlock Metal Roofing (PNW) Inc. has served the region since 1997 and handles these overlays routinely. The ICC-ES evaluation report ESR-1790 confirms code compliance for this method. Installation typically takes 2–4 days depending on roof size and complexity, and the interlocking design speeds work compared to traditional shingling.

Yes. Lebam averages about 49 cm of snow, 1578 mm of rain, roughly 34 freeze–thaw days a year, with peak wind gusts near 103 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.
