Interlock® Aluminum Roofing — all-climates performance specs for Wellesley, 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. |

What our customers are saying:
No need for improvement
The timeline was a little bit longer than what we expected. The cleanup wasn't perfect and part of that might have been due to the fact that I have a number of gardens around the house and maybe you can't see the debris in them.
There could have been better communication between me and my salesman.
Nothing.
from our initial inquiry to peoject completion our experience was great
I would highly recommend your company to anyone looking to have a metal roof installed.
Item 12 : We spoke of a $ 950.00 deduct from the bill for sign advertising on lawn. However deduct was not on my bill so sign was immediately removed. Unfortunately have had numerous inquirers about job and product. Without agreement I feel I'm not your rep for getting your more business.

Metal Roofing FAQs for Homeowners in Wellesley
The following metal roofing FAQs are designed specifically for homeowners in Wellesley, 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 Wellesley.
Does a metal roof handle Wellesley's snow load without ice dams?
Yes—aluminum's smooth surface and four-way interlocking design shed snow and melt water far more effectively than asphalt, reducing ice dam risk even during Wellesley's roughly 107 cm of annual snowfall and 88 freeze-thaw cycles. The lightweight panels (Slate at 0.41 lb/sq ft) mean no structural reinforcement, so you avoid the roof load concerns that come with traditional slate or tile. Snow guards are available if you want to manage sliding on steep pitches in your climate.
Will freeze-thaw cycles in Wellesley damage aluminum roofing?
Aluminum actually thrives in freeze-thaw environments because it contains no iron and cannot rust—the oxide layer on its surface self-heals when scratched. With about 88 freeze-thaw days per year in your region, traditional materials like wood, asphalt, and concrete tile crack, curl, or rot under repeated expansion and contraction, but roofing-grade 3105-H24 aluminum alloy (ASTM B209) is engineered for exactly these cycles. The Alunar 70% PVDF coating adds another 30-year warranty against degradation.
Can a metal roof withstand Wellesley's wind gusts?
The four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h), well above Wellesley's typical gusts to about 115 km/h. Each panel locks on all four sides, distributing wind load across the entire roof system rather than relying on fasteners alone. In a region with mean daily-max winds around 19 km/h and periodic stronger gusts, this engineered interlock design provides structural security that traditional shingles cannot match.
Is a metal roof good protection against hail in Ontario?
Absolutely—Interlock achieves UL 2218 Class 4, the highest impact rating available, and the warranty even covers perforation from hailstones up to 1.5 inches. That rating often qualifies homeowners for insurance discounts that can offset a meaningful portion of the roof cost. Combined with Wellesley's typical 779 mm of annual rainfall, you get a material that shrugs off both frequent wet weather and the occasional severe hail event without the cumulative damage asphalt shingles accumulate.
Why choose aluminum roofing instead of steel?
Steel rusts because it contains iron; aluminum cannot rust because it has no iron. Instead, aluminum develops a transparent oxide layer that self-heals when scratched—a permanent barrier against corrosion. Steel requires paint or galvanizing that deteriorates, especially in regions with freeze-thaw cycling like Wellesley (88 days per year). Aluminum roofing-grade alloy 3105-H24 with a two-sided Alunar 70% PVDF coating holds its integrity for decades without the maintenance overhead or eventual failure steel inevitably faces.
Do energy-efficiency metal roofs really cool a home?
Yes—energy-efficient Interlock colors have thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they reflect heat that asphalt absorbs. In a climate with about 2970 annual sunshine hours, that reflectivity reduces cooling load, especially during warm months. Cool Roof Rating Council certification confirms this benefit. While Wellesley's mean temperature is modest (8.9°C), the reduction in summer peak demand and the roof's durability mean long-term energy savings that stack up over the material's lifetime.
What's the real warranty on Interlock roofing?
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. It's also one-time transferable, giving the next owner an additional 50 years from completion. That means when you sell in Wellesley's market, the next owner gets decades of protection, and you avoid the asphalt cycle of replacing your roof every 15–20 years. In a freeze-thaw environment with 88 annual cycles, that non-prorated coverage against material failure is peace of mind most homeowners never get.
How long does metal roof installation take, and can it go over my existing roof?
Installation timelines vary with roof size and complexity, but Interlock Metal Roofing (Ontario) Ltd. can often complete residential projects in days, not weeks. More important: because aluminum is extraordinarily light—the Mediterranean Tile profile is about 96% lighter than concrete or clay tile—most installations can go directly over your existing asphalt without structural reinforcement. That saves time, disposal costs, and disruption. The four-way interlock system ensures a tight, weathertight seal without relying on mass to hold itself down.
Is a metal roof worth the upfront cost compared to asphalt?
It's the last roof you'll buy—a critical distinction over 50+ years. Asphalt fails every 15–20 years in Wellesley's climate (779 mm rain, 107 cm snow, 88 freeze-thaw days), triggering repeated tear-offs, disposal, and reinstallation. A metal roof eliminating that cycle, combined with potential insurance discounts (UL 2218 Class 4 hail rating), lower maintenance, and the transferable 50-year warranty that adds resale value, means the upfront premium typically recovers itself before you sell. Current promotions include interest-free payments for 3 months and savings of at least $2499 on installation.
How is a metal roof better for the environment than asphalt?
Aluminum is approximately 95% recyclable and can be recovered and reused indefinitely without degradation. Each asphalt reroof sends old shingles to a landfill—Wellesley homeowners would contribute multiple times over a 50-year period. Metal roofing breaks that cycle entirely: when it eventually reaches end-of-life (likely beyond your ownership), the aluminum returns to the recycling stream rather than a landfill. CALGreen verification confirms reduced maintenance requirements. In a region with about 2970 sunshine hours annually and decades of durability ahead, the environmental case compounds with every year the roof remains in service.
Is a metal roof a good choice for Wellesley’s climate?
Yes. Wellesley averages about 107 cm of snow, 779 mm of rain, roughly 88 freeze–thaw days a year, with peak wind gusts near 115 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.
