Review: November 2, 2021Completion: October 20, 2021

Unfortunately, after completing the first two thirds of a new roof on our house, we had persistent leaks each winter for five years, which caused serious damage to interior ceilings and hardwood floors, resulting in an insurance claim. It took a lot of effort including a lawyer's intervention to convince Interlock to finally engage a qualified engineer to determine the cause. Once this was done, Interlock agreed to a plan to fix it it, as well as to complete the final one third of our roof which we had held off on but then signed a contract to complete. Following initial leaks during first winter after new roof - send someone to inspect and take immediate action rather than simply observe it from the ground in late October when it was too late to even try to caulk. The next year, following additional leaks - immediately engage a qualified expert to investigate and resolve the problem before it became more serious. Respond sooner than five years after installation of initial new roof to resolve the leakages, and do so without requiring the client to engage a lawyer. Having signed a contract for the remaining one-third of the roof to be installed and taken a 25% deposit, do not have Interlock's lawyer then send us a letter stating they would no longer work on our home. Instead honour the contract, engage appropriate expertise, and actively try to resolve the outstanding annual leakage issues.

Review: August 11, 2016Completion: July 12, 2016

Some initial delay in communicating to us the final price quote, but this didn't hold things up.Minor issue but there was a math error on the original invoice, which eventually got sorted out.Another completed job site that was recommended for us to go and view before signing the contract did not exist, so a trip was wasted - probably a data base error.Would have preferred to be able to pay the entire bill on Visa, not just the deposit. This was not made clear until contract signing. Generally pretty happy with the work done, and anticipate completing the remaining area above the garage in the next year or two based on the current pricing structure.

Review: December 30, 2014Completion: October 22, 2014

We were extremely happy with them. There were a few materials backordered when they started the project, but they got those right away. We didn't even know that. We're very happy. People comment on it all the time. We haven't really experienced bad weather yet, but everything seems to be great.

Review: June 29, 2014Completion: April 4, 2014

When my shingle roof began to fail years before it should have I began a long process researching products and meeting with numerous contractors all of which offered differing materials and views of the work required. When I met with Barry of interlock roofing I new that they had a great product. From there I researched them extensively and signed with them. Now I have the best looking and best quality roof on my home and NEVER have to worry about it again. site cleanup and technician appearance

Metal Roofing FAQs for Homeowners in Almonte

The following metal roofing FAQs are designed specifically for homeowners in Almonte, 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 Almonte.

How does a metal roof handle Almonte's heavy snow and freeze-thaw cycles?

Aluminum's smooth, hard surface sheds snow more effectively than asphalt, reducing ice-dam risk during Almonte's typical 88 freeze-thaw days per year. The four-way interlocking panels are warranted for wind speeds up to 120 mph, so snow load and wind gusts averaging 17 km/h with peaks near 101 km/h won't compromise the seal. Unlike wood shakes, which split and warp, aluminum expands and contracts uniformly without trapping moisture—critical when your region averages about 120 cm of snow annually.

Why won't an aluminum metal roof rust like steel roofing would?

Aluminum contains no iron, so it cannot rust chemically—that's a physical impossibility. Instead, it develops a self-healing oxide layer that protects the metal underneath. Even if scratched during installation or by branches, that oxide reforms automatically. The Alunar 70% PVDF fluorocarbon coating (applied to both sides, warranted 30 years) adds a second defense layer. In Almonte's humid climate with 770 mm of rain annually, this dual protection ensures your roof won't degrade the way steel does in moisture.

Does freeze-thaw damage affect metal roofing the way it damages asphalt or wood?

No. Asphalt becomes brittle and cracks; wood absorbs freeze-thaw moisture and splits. Aluminum stays dimensionally stable through endless cycles. With about 88 freeze-thaw days per year in Almonte, this durability compounds over decades. Aluminum panels don't retain water in surface cracks, so expansion and contraction happen uniformly without internal damage. The four-way interlocking design accommodates slight panel movement, and the Class A fire-rated, non-combustible material resists the material fatigue that organic roofing experiences.

Can my older Almonte home support a metal roof, or do I need structural upgrades?

Most existing homes need no reinforcement. Interlock's Slate profile weighs about 0.41 lb/sq ft, and even the Mediterranean Tile (the heaviest) is roughly 96% lighter than concrete or clay tile. Your home's frame already carries the snow load—about 120 cm annually in Almonte—which weighs far more than any metal roof. This exceptional lightness means the roof installs directly over most existing structures and can even cover your current shingles, saving thousands on tear-off costs and avoiding asphalt in the landfill.

Is a metal roof worth the cost compared to asphalt shingles?

Metal roofing costs more upfront but is the last roof you buy. Asphalt shingles last 15–20 years and require tear-off (landfill waste), replacement, and repair cycles. Interlock's Guardian warranty is lifetime limited—non-prorated for the original owner, then transferable for 50 years to the next—covering rust, rot, splitting, cracking, curling, and impact loss. Over a 50-year period in Almonte's 770 mm rainfall and 150 cm snow climate, one metal roof replaces 2–3 asphalt installations. Current promotion: interest-free payments for 3 months and at least $2499 in savings.

Does Interlock metal roofing hold up in hailstorms, and could it lower my insurance?

Yes—the warranty covers perforation from hailstones up to 1.5 inches and carries a UL 2218 Class 4 impact rating, the highest available. Aluminum's hardness and four-way interlocking structure distribute impact energy across the roof. Some insurers recognize this durability and offer discounts; ask your agent. In regions with hail risk, metal roofs often qualify for lower premiums than asphalt. Combined with the 30-year coating warranty against fading and chalking, this durability means fewer claims and more predictable long-term costs.

Does a metal roof help cool my house or reduce heating costs in Almonte?

energy-efficient colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 reflect heat that asphalt absorbs, reducing cooling load in summer. Almonte receives about 2926 sunshine hours annually, so this reflectance compounds season to season. In winter, the hard surface and solid deck (over which underlayment installs) trap warmth efficiently. The Cool Roof Rating Council rating confirms measurable energy savings. Lighter color profiles minimize heat absorption during your region's typical 7.3°C mean temperature, lowering both air-conditioning and heating demand.

What profile options let me match my home's architectural style?

Interlock offers five profiles: Slate (clean, modern), Cedar Shingle (traditional New England), Shake (rustic, dimensional), Mediterranean Tile (Old World charm), and Standing Seam (contemporary, clean lines). Each is manufactured since 1998 in Delta, BC, with roofing-grade 3105-H24 / 3003-H24 aluminum and Alunar 70% PVDF coating, so durability is identical across all styles. The choice is purely aesthetic—pick the look that suits your home. All meet ICC-ES ESR-1790 code for Ontario, resist 101 km/h gusts, and shed Almonte's 770 mm annual rainfall equally well.

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

Almost none. Metal roofs don't require the annual inspections, patching, and replacement cycles of asphalt. Unlike wood shakes (which split, curl, and rot in Almonte's 150 cm snow and 88 freeze-thaw days), aluminum doesn't absorb moisture. The Alunar coating is warranted 30 years against chalking and fading (ASTM D4214/D2244), so no resealing. Debris washes away in rain; gutters stay cleaner because the smooth surface sheds leaves and branches. The CALGreen verification confirms reduced maintenance burden compared to traditional materials, translating to lower long-term ownership cost.

How long does installation take, and can I install over my existing roof?

Installation timeline depends on home size and weather, typically completed within days. Because Interlock panels weigh only 0.41–0.59 lb/sq ft, they install over most existing asphalt shingles—no tear-off required. This saves labor, eliminates landfill waste, and keeps your home watertight throughout. Installers follow ICC-ES ESR-1790 specifications for flashing and attachment, ensuring wind-speed warranties up to 120 mph hold. Almonte's typical 17 km/h winds with gusts to 101 km/h rarely interrupt installation. Local installer Interlock Metal Roofing (Ontario) Ltd. has served the region since 1998 and manages the full process.

Is a metal roof a good choice for Almonte’s climate?

Yes. Almonte averages about 150 cm of snow, 770 mm of rain, roughly 88 freeze–thaw days a year, with peak wind gusts near 101 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.
