Greely metal roofing FAQ

Will a metal roof hold up to Greely's freeze-thaw cycles?

Yes. Greely experiences about 89 freeze-thaw days per year, and aluminum's non-porous structure means water cannot penetrate the material itself—only the fasteners and seams matter. The four-way interlocking design and Alunar coating (warranted 30 years against weather degradation) eliminate the gaps where ice forms. Unlike asphalt shingles, which crack and curl as moisture expands and contracts, roofing-grade 3105-H24 aluminum simply flexes and returns to shape. The Guardian Warranty explicitly covers cracking and curling for the original owner's lifetime.

How does an Interlock metal roof handle Greely's heavy snow load?

Greely receives about 144 cm of snow annually, but aluminum's light weight—the Mediterranean Tile profile weighs just 0.59 lb/sq ft, roughly 96% lighter than clay or concrete tile—means no structural reinforcement is needed, even when installed over your existing roof. Snow slides off more cleanly on smooth metal than on asphalt, reducing ice dam formation. Optional snow guards can be installed if you prefer gradual shedding. The roof's 120 mph wind warranty also handles Greely's typical gusts up to 92 km/h without issue.

Are metal roof panels secure in Greely's wind gusts?

Absolutely. Greely's average gust speeds reach 92 km/h; Interlock's four-way interlocking aluminum panels are warranted to resist winds up to 120 mph (193 km/h) when installed to specification. The interlocking mechanism—not fasteners alone—transfers wind load across the entire panel array, distributing stress. This design has been tested under ICC-ES ESR-1790 evaluation and installed from coastal salt-air environments to Antarctica, where wind and environmental stresses are far more severe than Greely's conditions.

Can aluminum roofs rust like steel roofs?

No. Aluminum contains no iron, so it cannot rust chemically. Instead, aluminum forms a microscopically thin oxide layer when exposed to air—and this layer self-heals when scratched. Interlock uses roofing-grade 3105-H24 / 3003-H24 aluminum alloy per ASTM B209, coated with Alunar 70% PVDF fluorocarbon on both sides. That dual-sided protection is critical in humid climates like Greely's (883 mm annual rain), where moisture exposure is constant. The 30-year coating warranty covers chalking and fading, ensuring the oxide layer stays protected for decades.

Will hail damage my metal roof, and can I get insurance discounts?

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. Class 4 rating often qualifies homeowners for insurance discounts on premiums; contact your insurer with the product documentation. With 2903 annual sunshine hours and 89 freeze-thaw days, Greely's hail risk is real but manageable with this rating. The non-combustible aluminum also qualifies for Class A fire rating, which many insurers reward further.

How much maintenance does a metal roof need compared to asphalt or wood?

Minimal. Aluminum won't rot, split, curl, or require resealing like asphalt shingles or wood shake. You rinse debris twice yearly—less in Greely's 2903 sunshine hours, where biological growth is slower. The Alunar coating resists weathering for 30 years without repainting. Asphalt roofs require annual inspections, frequent repairs, and complete replacement every 15-20 years; wood shake needs ongoing treatment against rot and insects. Interlock's Guardian Warranty covers splitting, cracking, and curling for the original owner's lifetime, with no maintenance clause exclusions.

Is a metal roof worth the upfront cost over the life of the roof?

Yes. Asphalt roofs cost less initially but need replacement every 15-20 years; metal roofs last 50+ years with a transferable, one-time limited lifetime warranty (next owner gets 50 years from completion). Over 60 years, you'll replace asphalt 3-4 times versus zero times for metal. Current promotion: interest-free payments for 3 months and at least $2499 in savings on installation. Factor in no structural reinforcement needed (aluminum weighs ~0.59 lb/sq ft versus 900+ for tile), lower maintenance, potential insurance discounts, and resale value—metal becomes the final roof you buy.

Will a metal roof help reduce cooling costs in summer?

Yes. Interlock's energy-efficient colors reflect heat rather than absorbing it like dark asphalt. Thermal emissivity reaches 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny), meaning less heat enters your home. With Greely's 2903 annual sunshine hours, reflective coatings compound your savings over decades. The Cool Roof Rating Council rates these panels; they measurably reduce the roof surface temperature compared to standard asphalt. Combined with aluminum's non-combustible properties (Class A fire rating available), a reflective metal roof also qualifies for some utility rebates and CALGreen verification for reduced maintenance burden.

Can you install a metal roof over my existing roof, and how long does it take?

Yes. Aluminum's featherweight construction (Cedar Shingle at 0.41 lb/sq ft, Slate slightly higher) installs over most existing asphalt or wood roofs without structural reinforcement, saving demolition costs and time. A typical residential installation takes 3-5 days depending on roof complexity and weather. Greely's average rainfall of 883 mm per year means your project should be scheduled for drier weeks; our local installer, Interlock Metal Roofing (Ontario) Ltd., has served the region since 1998 and coordinates timelines around typical spring and summer conditions. Installation to spec is critical for the 120 mph wind warranty and proper interlocking performance.

Are metal roofs more sustainable than asphalt?

Aluminum is approximately 95% recyclable; at end of life, your roof becomes raw material for new products rather than landfill waste. Asphalt shingles, by contrast, generate millions of tons to landfills annually because they cannot be cost-effectively recycled. Greely's 144 cm of snow and 883 mm of rain accelerate asphalt degradation, shortening replacement cycles and multiplying landfill impact. Interlock's roofing-grade 3105-H24 aluminum eliminates the tear-off-to-landfill cycle entirely. The manufacturing process in Delta, BC since 1998 has established supply chains for recycled aluminum, reducing embodied carbon. Choosing metal aligns with CALGreen sustainability standards and reduces your home's environmental footprint over 50+ years.
