Metal Roofing in Port Moody, British Columbia

Metal roofing sheds snow and ice far better than asphalt because the smooth, hard surface won't trap moisture the way porous shingles do—critical in a region that averages about 120 cm of snow yearly and experiences roughly 37 freeze-thaw cycles per year. The four-way interlocking panels create a unified thermal mass that resists ice dam formation. Optional snow guards can be installed where needed to manage roof runoff safely. Aluminum's light weight also means no structural concern even if snow accumulates temporarily.

No—the four-way interlocking design and gravity-driven panel overlap direct water downslope; it never sits in seams. Port Moody receives approximately 2471 mm of annual rainfall, and these roofs have performed in far wetter climates, including coastal salt-air environments and Antarctic research stations. The panels themselves are seamless aluminum (no fasteners breaking the skin), and when installed over a solid deck with underlayment—which we do—the protection is equivalent to or better than traditional asphalt. Water simply cannot find a path through.

Aluminum cannot rust because it contains no iron; instead, it forms a self-healing oxide layer that actually protects the metal underneath. Steel ruofing corrodes and weakens over time, especially in Port Moody's coastal salt-air exposure. Our 3105-H24 / 3003-H24 roofing-grade aluminum alloy is paired with a Alunar® 70% PVDF coating applied to both panel sides—warranted 30 years against chalking and fading—so corrosion simply isn't a failure mode. This is why we've installed roofs from ocean-view homes to extreme environments without rust concerns.

Absolutely. Port Moody's typical wind gusts reach about 95 km/h, and our metal roof is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking panels lock together so tightly that wind cannot lift or separate them—there's no flutter, no individual panel failure. The system is rated UL 2218 Class 4 for impact, meaning it handles hail and wind-driven debris the same way. You get a roof engineered for the worst-case gust without compromise.

No structural reinforcement is needed. The Interlock Tile profile, for example, installs at just 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so it won't overload your existing frame. Most homes can accept a metal roof installation directly over asphalt shingles without any upgrades. This lightweight advantage saves thousands in structural work that slate or clay would require, yet delivers the same authentic visual appeal. It's one reason metal is the practical choice for retrofits across Metro Vancouver.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—meaning there's no time limit and no step-down in coverage. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance from day one through the roof's life. The warranty is also one-time transferable, giving the next owner 50 years of protection from completion. Combined with aluminum's inherent durability and the 30-year coating warranty, this is genuinely the last roof you'll need to install.

Yes, because you replace asphalt every 15–25 years, then haul it to landfill and start over; a metal roof lasts your lifetime and transfers value to the next owner. Over 50 years, asphalt costs thousands in repeated tear-offs, labor, and waste disposal. Metal costs more initially but eliminates that cycle entirely. Right now, we're offering interest-free payments for 3 months and savings of at least $2499 on installation. When you factor in zero replacement, minimal maintenance, energy savings, and a transferable warranty, the math strongly favors metal.

Yes—we manufacture five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile, each with authentic texture and shadow lines. Every profile uses the same four-way interlocking, non-rusting aluminum construction, so you're choosing appearance, not sacrificing performance. The Mediterranean Tile, for instance, looks indistinguishable from a distance but weighs 96% less than clay tile and won't crack under Port Moody's 37 annual freeze-thaw days. Pick the aesthetic that matches your home; the durability is identical across all profiles.

Significantly. Aluminum is approximately 95% recyclable, and Interlock panels manufactured in Delta, BC stay out of landfills at end-of-life. Asphalt, by contrast, is torn off every 15–25 years and buried; Port Moody's heavy annual rainfall of about 2471 mm accelerates asphalt degradation, shortening replacement cycles even further. Metal breaks the tear-off-to-landfill cycle entirely. The energy-efficient colors also reflect solar heat with emissivity up to 0.84, reducing cooling load. One roof, recycled indefinitely, zero waste.
