Interlock® Aluminum Roofing — all-climates performance specs for Kawartha Lakes, Ontario
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

Metal Roofing FAQs for Homeowners in Kawartha Lakes
The following metal roofing FAQs are designed specifically for homeowners in Kawartha Lakes, Ontario. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Kawartha Lakes.
How does a metal roof handle Kawartha Lakes' heavy snow loads?
Metal roofs shed snow and ice more effectively than asphalt because the smooth, hard surface resists adhesion and the lightweight aluminum panels won't sag under snow weight the way heavier materials do. Kawartha Lakes averages about 137 cm of snow yearly, and freeze-thaw cycles happen roughly 88 days per year—conditions that crack and buckle asphalt shingles over time. Interlock's four-way interlocking panels stay watertight through the melt cycles, and you can install snow guards if you want controlled shedding rather than avalanche-style dumps.
Will freeze-thaw cycling damage aluminum metal roofing?
No. Aluminum has no iron content, so it cannot rust—the oxide layer that forms on its surface actually self-heals when scratched, even through repeated freeze-thaw stress. With about 88 freeze-thaw days per year in Kawartha Lakes and mean annual temperatures of 7.9°C, your asphalt shingles will crack and curl while your metal roof stays intact. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading, so the finish holds up through decades of temperature swings.
Can metal roofing withstand Kawartha Lakes wind gusts?
Yes, completely. Typical daily winds run about 18 km/h, but gusts regularly hit 104 km/h—and Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. That's 85% stronger than the peak gust data shows you need. The interlocking seams work like a chain: each panel locks to its neighbors in four directions, so wind pressure that would lift a loose shingle simply tightens the grip. One storm won't send you shopping for a new roof.
Do I need to reinforce my house for metal roofing?
Not at all. Interlock's lightweight aluminum panels install at roughly 0.41 to 0.59 pounds per square foot depending on the profile—the Mediterranean Tile profile is about 96% lighter than concrete or clay tile, so your existing roof structure handles the load with ease. Most homes can even install directly over their current asphalt shingles, which saves money on tear-off and disposal. A slate or tile look without the structural headache or the cost of engineering reinforcement.
What's the hail rating on Interlock metal roofing, and does it affect insurance?
Interlock earns UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. That's real peace of mind in a climate where hail can arrive with summer thunderstorms. Many insurers recognize the durability and may offer discounts; check with your agent, but the bottom line is you're covered by warranty even if a storm causes damage. No deductibles, no gotchas—that's a luxury asphalt won't give you.
Does reflective metal roofing save energy in Kawartha Lakes?
energy-efficient colors reflect heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. Kawartha Lakes gets about 2935 sunshine hours per year, so reflective coatings genuinely reduce cooling costs in summer and lower your roof's surface temperature during warm days. Asphalt absorbs that heat and radiates it into your attic; aluminum bounces it back and keeps your air conditioning working smarter, not harder.
How much maintenance does a metal roof need versus asphalt shingles?
Metal roofing requires far less. Asphalt shingles lose granules, curl in UV light, and need moss treatment in damp climates; Interlock aluminum never rots, cracks, or splits because there's nothing organic to degrade. Kawartha Lakes receives about 785 mm of rain yearly plus 137 cm of snow, and that water simply runs off the hard surface. The Alunar 70% PVDF coating is verified CALGreen-compliant for reduced maintenance, so you'll spend money on gutters and flashing upkeep, but your roof itself stays sound for decades without intervention.
Is metal roofing worth the upfront cost over the life of the roof?
Yes, when you compare the total cost of ownership over 40+ years. A typical asphalt roof lasts 15-20 years in Kawartha Lakes' climate and requires tear-off, disposal, and reinstall—two or three times in a homeowner's lifetime. Interlock comes with a lifetime limited, non-prorated material warranty for the original owner, plus a transferable 50-year term for the next owner. Current promotion: interest-free payments for 3 months and save at least $2499 on installation. The last roof you buy is the only one you need.
Why doesn't aluminum roofing rust like steel?
Aluminum roofing contains zero iron—iron is what rusts when exposed to oxygen and moisture. Roofing-grade 3105-H24 and 3003-H24 aluminum alloy (per ASTM B209) forms an invisible oxide layer on its surface that, unlike steel rust, actually self-heals when scratched. Kawartha Lakes' 785 mm annual rainfall and 137 cm of snow mean constant moisture exposure. Steel would require constant coatings and maintenance; aluminum simply shrugs off freeze-thaw cycles and rain. The Alunar 70% PVDF finish on both sides adds another 30-year warranty layer against salt-air or road-spray corrosion.
What metal roofing profiles does Interlock offer for Kawartha Lakes homes?
Five styles: Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam. Each profile is achieved through four-way interlocking aluminum panels, so you get the authentic look of slate, hand-split shake, or clay tile without the weight, fragility, or maintenance. Slate replicates timeless texture; Cedar Shingle offers cottage charm; Shake delivers rustic character; Mediterranean Tile suits heritage or contemporary homes; Standing Seam provides a clean, modern edge. Choose the aesthetic that fits your home—all five are built from the same durable, non-rusting aluminum core and installed by Interlock Metal Roofing (Ontario) Ltd., serving the region since 1998.
Is a metal roof a good choice for Kawartha Lakes’s climate?
Yes. Kawartha Lakes averages about 137 cm of snow, 785 mm of rain, roughly 88 freeze–thaw days a year, with peak wind gusts near 104 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
