Metal Roofing in Kensington, Prince Edward Island — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt shingles, which trap moisture and freeze. With about 197 cm of snow per year and roughly 71 freeze-thaw days cycling through your roof, that constant expansion and contraction degrades asphalt but leaves aluminum unaffected. Interlock's four-way interlocking panels lock together so tightly that ice dams can't exploit seams, and the lightweight design—the Shake profile weighs just 0.58 lb/sq ft—means no structural overload from accumulated snow. Snow guards are available if you want controlled shedding onto walkways.

No. Aluminum expands and contracts but does not crack, split, or curl—the material is inherently stable through thermal cycling. With 71 freeze-thaw days per year and an average temperature of 7.2°C, your roof experiences constant stress that would crack asphalt, wood shingles, and concrete tile. The roofing-grade 3105-H24 aluminum alloy used in every Interlock panel is chosen precisely for this durability. The Alunar 70% PVDF coating on both sides adds a protective barrier rated 30 years against degradation, so the panel itself outlasts the coating.

Aluminum cannot rust because it contains no iron; instead, it develops a transparent oxide layer that actually protects the metal underneath. This self-healing oxide is why Interlock panels installed in coastal salt-air environments and even an Antarctic research station show zero corrosion after decades. Kensington's 891 mm of annual rainfall and maritime exposure mean traditional steel roofing would require constant maintenance to prevent rust staining and decay. Aluminum simply weathers—it doesn't deteriorate. The Alunar coating on both sides of each panel provides an extra 30-year warranty against chalking and fading, giving you dual protection.

Yes, safely. Kensington experiences typical daily-max winds of about 27 km/h with gusts reaching 165 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 specification. The panels lock together on all four edges, eliminating the weakness that lets high wind slip under traditional shingles and tear them off. Each panel anchors mechanically, not with nails alone. The ICC-ES evaluation report ESR-1790 confirms the system's compliance with IBC and IRC wind requirements, so your roof won't budge in a PEI nor'easter.

Metal roofs are extremely hail-resistant and rated UL 2218 Class 4—the highest impact classification available. Interlock's warranty even covers perforation from hailstones up to 1.5 inches. Many insurers offer discounts for Class 4 roofing because hail claims are rare, and you should ask your provider about savings when you have the metal roof installed. Aluminum is rigid and does not dent easily under typical impacts. While Kensington's hail risk is lower than prairie provinces, the protection is there if a severe storm passes through, and the peace of mind often translates to lower premiums over the roof's lifetime.

Over the roof's life, metal is cheaper. An asphalt roof lasts 15–20 years and requires replacement; a metal roof installed today will outlive you and transfer to the next owner. The Guardian warranty is lifetime limited and non-prorated for the original owner, then one-time transferable for 50 years from completion—that's protection no asphalt shingle matches. You avoid tear-off costs, disposal fees, and the labor of multiple replacements. Maritime Metal Roofing Ltd. is currently offering interest-free payments for 3 months and savings of at least $2,499 on installation, which further improves the math. Spread the cost over 40+ years and the annual cost is trivial.

No reinforcement is required. Interlock aluminum is extraordinarily light—the Mediterranean Tile profile weighs about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile. Even the heaviest Interlock profile installs without structural upgrades, and the entire system can go directly over most existing asphalt roofs, saving you the cost and disruption of tear-off. Your home's framing already supports the weight of 197 cm of snow accumulation, and the metal roof will never exceed that load. This is a major advantage in PEI where older homes were built to handle Maritime weather but may not tolerate the dead load of slate or tile.

The Guardian warranty is lifetime limited for the original owner and covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance—essentially every failure mode that could occur. It is non-prorated, meaning you get full coverage for your entire ownership. The warranty transfers once to the next owner for 50 years from completion, which adds real value to your home's sale. The Alunar coating itself carries a separate 30-year warranty against chalking and fading. This combination of material protection and coating durability reflects Interlock's confidence in its product: the company has manufactured these panels since 1998 and continues to back them fully.

Virtually none. With about 2,749 annual sunshine hours and 891 mm of rainfall, your roof gets natural cleaning from rain and weathering that removes debris and algae growth. Metal does not rot, split, or curl like wood shingles; it does not develop moss or mold like asphalt; it does not crack like concrete tile. You inspect gutters and flashings the same way you would on any roof, but the roof surface itself is inert. The Alunar 70% PVDF coating is rated by ASTM D4214 and D2244 standards and carries a 30-year warranty—typical maintenance is visual inspection every few years and removal of overhanging branches. Many owners go years without touching their metal roof.

Yes. Interlock offers five distinct profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each four-way interlocking aluminum panel replicates the visual profile of the traditional material while delivering the durability and weather resistance of aluminum. The Slate and Standing Seam suit modern or contemporary homes, while Cedar Shingle, Shake, and Mediterranean Tile appeal to traditional or heritage properties common in Kensington. All are installed the same way and carry identical performance ratings: UL 2218 Class 4 hail, 120 mph wind warranty, and ICC-ES compliance. Your choice is purely aesthetic; the weather protection is identical across all styles.

Yes. Kensington averages about 197 cm of snow, 891 mm of rain, roughly 71 freeze–thaw days a year, with peak wind gusts near 165 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.
