Metal Roofing in Chase, British Columbia — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow and ice far better than asphalt because the smooth, hard surface resists ice bonding and allows snow to slide before it accumulates into dangerous loads. With about 153 cm of annual snowfall in Chase, this matters—ice dams form when heat loss melts snow at the roof edge, but aluminum's 0.84 thermal emissivity and light weight (just 0.41 lb/sq ft for Shingle profile) work together to keep the whole roof plane at uniform temperature, eliminating the warm-spot problem. The four-way interlocking panels shed water before it refreezes at the eaves. Snow guards are available if you want to control the slide.

Freeze-thaw damage happens to materials that absorb water and expand when frozen—aluminum does neither. Your region averages about 85 freeze-thaw days per year, and that's exactly where aluminum outperforms wood, asphalt, and concrete tile. Aluminum alloy 3105-H24 contains no iron, so it cannot rust or rot; the oxide layer that forms on the surface actually self-heals when scratched, getting stronger rather than weaker over time. The Alunar 70% PVDF coating adds a 30-year warranty against chalking and fading even as temperatures swing from below freezing to above. The material simply doesn't degrade from the wet-freeze-thaw cycle.

Chase experiences gusts up to 90 km/h, and Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—that's well above your local exposure. The interlocking design means each panel is mechanically fastened to the one beside and below it, distributing wind load across the entire roof plane rather than relying on fasteners alone. The ICC-ES evaluation report ESR-1790 validates this for IBC/IRC code compliance. You're not just getting fastened panels; you're getting a unified system engineered for wind uplift that exceeds what your region will throw at it.

You almost certainly don't need structural reinforcement. The Interlock Mediterranean Tile profile, which replicates the weight and appearance of clay or concrete tile, installs at just 0.59 lb/sq ft—about 96% lighter than actual tile. Even the heavier Shake profile weighs only 0.58 lb/sq ft. Most homes built to code since the 1970s can support asphalt shingles (which weigh about 2–3 lb/sq ft), so aluminum is literally a fraction of that load. This light weight means installation is faster, costs less, and the roof can go directly over most existing roofing, avoiding tear-off labor and landfill waste. Your home's framing is already strong enough.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. That toughness translates directly to insurance savings; many insurers offer discounts for Class 4 roofing because the claims history is so strong. The aluminum's hardness and the interlocking design distribute impact energy across the panel and into the structure below, so the roof resists both denting and puncture. After 27 years of installation in variable North American climates, Interlock's hail performance is proven. Contact your insurer with the UL rating—most will recognize the premium reduction immediately.

Metal roofing's reflectivity makes a real difference on sunny days. Chase gets about 3170 sunshine hours per year, and energy-efficient Interlock colors offer initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they bounce back heat that asphalt absorbs and re-radiates into your attic. On a 20°C day with strong sun, that difference compounds through the cooling season. The Cool Roof Rating Council rates Interlock's reflective profiles for measurable cooling load reduction. In a heating-dominant climate, you won't see dramatic summer savings, but you'll eliminate the peak heat gain that drives AC use on the hottest days, smoothing your load profile and reducing overall consumption.

A metal roof needs almost none. Asphalt shingles deteriorate from UV exposure and weather, wood shakes split and rot, and clay tile cracks and spalls—all require regular inspection and repair. Aluminum doesn't degrade, rot, or lose structural integrity, so maintenance is limited to keeping gutters clear and inspecting fasteners after extreme weather. The Alunar coating is warranted for 30 years against chalking and fading, so repainting isn't in your future. Chase's 388 mm of annual rainfall rinses the roof naturally. The CALGreen standard recognizes metal roofing for reduced maintenance burden. Over a 50-year lifespan, you'll replace an asphalt roof twice and spend hundreds on upkeep; metal roofing's maintenance cost approaches zero.

Metal roofing costs more upfront than asphalt—typically 2–3 times the shingle price—but the math changes over time. An asphalt roof lasts 15–25 years and then goes to landfill; you'll reroof twice in the time a metal roof lasts 50+ years with the original owner's lifetime limited warranty (transferable for 50 years to the next owner). Metal's zero maintenance, no repairs, and near-certain 50-year lifespan mean you're buying your last roof. Coupled with the current regional promotion—interest-free payments for 3 months and at least $2499 in savings on installation—the total cost of ownership is lower than two asphalt roofs over the same period. You're not paying more; you're paying once and walking away.

Steel rusts because iron oxidizes when exposed to water and oxygen—aluminum cannot rust because it contains no iron. Instead, aluminum naturally forms a microscopically thin oxide layer that protects the metal beneath; when that layer is scratched, it self-heals in the presence of air and moisture. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a two-sided Alunar 70% PVDF fluorocarbon coating that adds a durable barrier against salt spray and wet conditions. Since 1998, Interlock panels have been installed in coastal salt-air homes and even Antarctic research stations—environments far harsher than anything in the Thompson region. In a climate with 153 cm of snow melt and 388 mm of rain per year, rust-proof construction isn't optional; it's essential.

Interlock Metal Roofing (BC) Ltd. has served the Thompson region since 1983—over 40 years of local installation experience. The company manufactures aluminum panels in Delta, BC, so you're buying from a British Columbia manufacturer with a local installer who knows Chase's climate, typical roof styles, and building practices. When you need a roof inspection, warranty service, or snow-guard adjustment, you're calling someone who's worked in your neighborhood, not a third-party contractor hundreds of kilometers away. The 40-year local track record and ICC-ES code compliance (ESR-1790) mean the installer understands both the product and the regional requirements. That combination is rare and valuable.

Yes. Chase averages about 153 cm of snow, 388 mm of rain, roughly 85 freeze–thaw days a year, with peak wind gusts near 90 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.
