Metal Roofing in Vancouver, British Columbia

No. Interlock roofs use roofing-grade 3105-H24 aluminum alloy, which contains no iron and therefore cannot rust. Aluminum's oxide layer self-heals when scratched, providing inherent corrosion resistance without ongoing maintenance. With Vancouver averaging 2471 mm of rain annually and coastal salt-air exposure, this non-rusting property is a critical advantage over steel, which requires continuous coating vigilance. The Alunar 70% PVDF fluorocarbon finish on both panel sides adds 30-year protection against chalking and fading, measured to ASTM standards, ensuring your roof's finish lasts as long as its structure.

Metal roofs shed snow and ice more effectively than asphalt due to their smooth, hard surface and low friction. Vancouver receives about 152 cm of snow per year across roughly 37 freeze–thaw cycles, conditions that crack and curl asphalt shingles but leave aluminum unaffected. The four-way interlocking panels lock together tightly, preventing water infiltration even when ice dams form. Snow guards can be added if you want to control roof-to-ground snow release. Aluminum's rigidity and lack of expansion-contraction issues make it genuinely superior in your climate's repeated freeze cycles.

Heavy, sustained rainfall is where four-way interlocking shines. Vancouver's 2471 mm annual rainfall puts constant stress on roof seams and fasteners—traditional vulnerabilities in asphalt and even some metal systems. Interlock's locking mechanism creates a labyrinth that sheds water across multiple panel edges before it reaches any fastener. Combined with proper underlayment and solid deck installation, this design resists leak initiation far more reliably than nailed shingles that separate and curl over 2788 sunshine hours and countless wet days. Each interlocking point is engineered to shed water, not trap it.

Yes. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Vancouver's typical gusts reach about 95 km/h, well within this rating. The four-way interlocking system locks each panel to its neighbors on all edges, distributing wind load across the entire roof rather than concentrating force on individual fasteners. This is fundamentally different from shingle systems, where high gusts can lift and separate edges. Even winter storms that approach your region's gust limits will not compromise an Interlock installation.

Almost certainly yes, even without structural reinforcement. Interlock's Mediterranean Tile profile installs at only 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. This exceptional lightness means no costly beam upgrades in most homes. By contrast, traditional tile demands expensive structural analysis and reinforcement. You can even install Interlock Tile over your existing asphalt roof without removing it, saving thousands in tear-off labor and landfill disposal. The Slate profile is lighter still at 0.41 lb/sq ft. Your house was almost certainly not engineered for heavy tile, but it is engineered for Interlock.

Interlock manufactures five profiles: Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each replicates the texture and shadow lines of its namesake material in genuine aluminum. Slate mimics quarried stone, Cedar Shingle captures the dimensional look of hand-split wood, Shake offers a rougher grain, Mediterranean Tile echoes clay barrel profiles, and Standing Seam delivers clean contemporary lines. All five are available in multiple colors, all ICC-ES evaluated (ESR-1790), and all non-combustible options qualify for Class A fire rating. Your choice of style doesn't compromise durability or warranty—only aesthetics shift.

Minimal. Asphalt shingles require regular inspection for curling, cracking, and moss growth; wood shakes split and rot; tile cracks under freeze-thaw stress. Aluminum resists all three. Vancouver's 37 annual freeze–thaw cycles will never crack Interlock panels, and the non-combustible aluminum surface doesn't harbor moss or mold like asphalt does. An occasional rinse after heavy rain or pollen season maintains appearance. The Alunar finish is CALGreen-verified for reduced maintenance requirements. Over a 50-year roof life, you'll spend far less time and money on repairs than any traditional material.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the failures that plague asphalt, wood, and concrete tile over decades. You also receive a one-time transferable warranty: the next owner is protected for 50 years from completion. This dual-owner protection reflects Interlock's confidence in longevity. Coupled with the 30-year Alunar coating warranty and UL 2218 Class 4 impact rating, you're buying the last roof you'll install, plus peace of mind for whoever buys your home after.

Yes. Aluminum is non-combustible and cannot ignite or contribute fuel to a fire. Interlock offers Class A fire rating on all profiles—the highest available—when ordered in non-combustible specification. This is a decisive advantage over asphalt shingles, which are combustible and vulnerable to flying embers in wildfire zones. While Vancouver's urban climate is lower-risk than interior regions, Class A rating reduces insurance premiums and provides absolute certainty your roof won't accelerate fire spread. ICC-ES evaluation ESR-1790 confirms this rating across all approved applications.
