Metal Roofing in Parksville, British Columbia

No — Interlock uses roofing-grade 3105-H24 aluminum alloy, which contains no iron and cannot rust. Aluminum develops a protective oxide layer that actually self-heals when scratched, so it thrives in wet climates. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel for extra defense against salt air and coastal moisture. You're looking at a roof that gets tougher with age, not weaker.

Aluminum panels shed snow and ice far better than asphalt. The smooth, interlocking design and tight seams prevent water pooling and ice dam formation, which is critical during Parksville's 24 annual freeze-thaw cycles when melting and refreezing are constant. Snow slides cleanly off steep profiles like Shake and Slate; optional snow guards let you control where it lands. The four-way interlocking system means water finds no way in, and you avoid the interior damage asphalt roofs suffer when ice backs up under shingles.

Yes — the warranty covers wind speeds to 120 mph (193 km/h) when installed to spec. Interlock's four-way interlocking aluminum panels lock together, so wind can't peel or lift them like individual shingles. Gusts averaging around 17 km/h with occasional peaks are well within the design margin. Coastal homes from BC to Antarctica have stood the test; your roof won't move.

No structural reinforcement needed. Interlock's Mediterranean Tile profile weighs about 0.59 lb/sq ft — roughly 96% lighter than real concrete or clay tile. This means it installs directly over most existing roofs without costly framing upgrades. Older homes that would struggle under genuine tile have no trouble with metal. You get the traditional look without the engineer's invoice and without tearing off your existing roof if it's in decent shape.

The four-way interlocking seams are engineered so water has nowhere to go but off the roof. Unlike overlapping shingles where rain can be driven backward under seams, each Interlock panel locks to its neighbors on all four sides, creating a unified waterproof surface. The ICC-ES ESR-1790 evaluation confirms the design for IBC/IRC compliance. Heavy Vancouver Island rain is exactly what these panels were designed for — they've been installed on coastal homes since 1998 without the leak issues that plague asphalt.

Virtually none compared to asphalt, wood, or tile. No annual inspections for curled or missing shingles, no moss treatment, no tar sealing. The Alunar 70% PVDF finish is warranted 30 years against chalking and fading, so the color stays true through Parksville's 2,980 annual sunshine hours. A periodic rinse in salty or dusty conditions is all you do. The CALGreen verification confirms the roof is certified for reduced maintenance, which means lower long-term cost and less hassle.

energy-efficient colors reflect sunlight rather than absorb it, reducing cooling load year-round. The Aged Copper Penny finish achieves solar reflectance up to 0.55 and thermal emissivity of 0.84, which means it bounces heat that asphalt absorbs and radiates. Over Parksville's 2,980 sunshine hours annually, that reflectance adds up to measurable savings. The Cool Roof Rating Council rating backs the math. You'll see the benefit on your cooling bills, especially if you're in a south-facing home or converting from dark asphalt.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That means no degradation schedule; you're covered the entire time you own the home. It's also one-time transferable, giving the next owner 50 years from completion. Few roofs — metal or otherwise — offer that kind of peace of mind. It's the last roof you'll buy.

Over the roof's life, yes. Asphalt typically lasts 15–20 years and requires tear-off and replacement — labor and landfill cost included each time. Interlock is a one-time install with no replacements, minimal maintenance, and a transferable warranty that covers the next owner for 50 years. Current promotion offers interest-free payments for 3 months and saves at least $2,499 on installation. When you factor in asphalt's repeated cycles over 50 years, metal is the cheaper choice long-term — plus you avoid the tar-off-to-landfill cycle entirely.

Yes — choose from five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the texture and shadow depth of traditional materials using four-way interlocking aluminum panels. Slate and Cedar Shingle suit heritage homes; Shake offers rustic character; Tile gives Mediterranean flair; Standing Seam is modern and clean. All five are manufactured in Delta, BC, installed locally since 1983, and come in multiple colors. You pick the look you want, then get the durability and low maintenance aluminum delivers — no compromises.
