Metal Roofing in Newmarket, Ontario — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow and ice far more effectively than asphalt because aluminum's smooth surface prevents ice damming — critical in a region that sees about 120 cm of snow annually and 86 freeze-thaw days per year. The four-way interlocking panels lock moisture out at seams, eliminating the gaps where ice can form and cause structural damage. Unlike wood shakes that absorb freeze-thaw stress and split, or asphalt that becomes brittle in repeated thaw cycles, roofing-grade 3105-H24 aluminum expands and contracts uniformly without degradation. Snow guards are available if you want to control runoff.

Aluminum cannot rust because it contains no iron — iron is what oxidizes and creates rust. Instead, aluminum develops a thin, invisible oxide layer that actually protects the underlying metal. When that layer is scratched, it self-heals naturally. Our Alunar 70% PVDF fluorocarbon coating, applied to both sides of every panel and warranted for 30 years against chalking and fading, adds a second line of defense. In Newmarket's humid climate with about 780 mm of annual rain, this two-layer protection means you're not fighting corrosion — you're simply maintaining a roof that doesn't degrade from moisture.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist sustained winds of 120 mph, well above Newmarket's typical gusts around 113 km/h. The interlocking design means each panel is mechanically locked to its neighbors on all four sides — wind can't lift a single panel without breaking the whole system. Installation to spec is the key: proper fastening into solid deck creates a fail-proof bond. That's why we back it with a warranty covering wind damage up to 120 mph. In a region where autumn and winter gusts regularly test your roof, that margin of safety means sleep at night.

Interlock achieves UL 2218 Class 4, the highest hail impact classification available, and the warranty even covers perforation from hailstones up to 1.5 inches. Class 4 means the roof passed impacts from 2-inch steel balls dropped from 20 feet. Many homeowners see insurance discounts for this rating — check with your insurer, as several offer breaks for non-combustible roofs with Class 4 impact ratings. Combined with the roof's 120-year lifespan and non-prorated lifetime warranty, underwriters recognize you're eliminating a major claim category. Contact your broker early in the process to confirm your specific discount.

Yes, in nearly every financial scenario. Asphalt costs less upfront but requires replacement every 15-20 years, plus disposal fees, labor, and disruption each cycle. Over 60 years, you'd reroof 3-4 times — that's four sets of labor, permit fees, and landfill waste. Interlock, backed by a non-prorated lifetime warranty and installed since 1998 with zero documented failures, keeps you out of that cycle permanently. The weight advantage also helps: at 0.41 lb/sq ft, it installs over most existing roofs, avoiding costly tear-off and structural work. Current promotion: interest-free payments for 3 months and save at least $2499 on installation. Run the 30-year math and the answer becomes clear.

Installation typically takes 3-7 days depending on roof size and complexity. Because Interlock panels are extraordinarily light — the Mediterranean Tile profile is 96% lighter than concrete or clay tile — they can install directly over existing asphalt shingles in most cases, eliminating a tear-off phase that can add weeks and thousands in labor. This also means no building permits for removal, less disruption, and no landfill impact from your old roof. The solid-deck underlayment and four-way interlocking seams create a complete envelope immediately. We'll inspect your current structure during the pre-install walk and confirm whether an overlay or teardown is the right call for your home.

energy-efficient Interlock colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 reflect heat that dark asphalt absorbs and radiates into your home. The Cool Roof Rating Council verified these values — they're measured, not marketing claims. In a region with about 3017 sunshine hours per year, that reflectance compounds over spring, summer, and fall. You'll see the biggest cooling benefit in months when Newmarket averages above 15°C, but the real payoff is consistency: a reflective roof stays stable in temperature swings and reduces HVAC strain year-round. Lower cooling costs and reduced peak demand also qualify you for potential utility rebates — check with your local provider.

Aluminum is non-combustible and Interlock is available with a Class A fire classification — the highest rating for fire resistance. Non-combustible means the material will not ignite or contribute fuel to a fire, even in extreme heat. Class A rating means it resists severe fire exposure without spreading flames. This matters in any neighborhood, but particularly in regions with wildfire exposure or dense housing. The roof itself won't burn, and it won't carry fire to adjacent structures. Combined with the metal's durability against wind-blown embers and flying debris from nearby fires, you've got a passive safety feature that lasts 120 years and requires no maintenance.

Interlock aluminum is approximately 95% recyclable at end of life — it has scrap value and will be reclaimed by recyclers, not sent to a landfill. Asphalt shingles, the material you're replacing, cannot be recycled: they go to landfill, where they off-gas and break down for decades. Over your roof's 120-year lifespan, you'll generate zero roofing waste; a conventional asphalt homeowner replaces their roof 5-6 times and sends 5-6 tons of shingles to waste. Interlock is CALGreen-verified for reduced maintenance, meaning no chemical treatments, no frequent repairs requiring material shipment. The aluminum itself comes from recycled sources more affordably each year. This isn't a marketing angle — it's physics: metal doesn't degrade like cellulose or asphalt.

Interlock Metal Roofing (Ontario) Ltd. has served the Newmarket region and South-Central Ontario since 1998 — the same year the product was first manufactured in Delta, BC. That means your installer knows this climate intimately: the 86 annual freeze-thaw cycles, the 117 cm snow loads, the 113 km/h gusts, and the installation details that make a metal roof perform in these exact conditions. Factory-trained crews handle every install to spec, ensuring your 120 mph wind warranty, Class 4 hail rating, and lifetime coverage are all enforceable.
