Ottawa, ON Metal Roofing: Thrilled Homeowner Review of Aluminum Roof Installation and Crew
Ottawa, ON
Rino Z.
Loving the roof. Sorry, it had to take a lot of your emails, but I’m really happy it is done.
John (never got his last name) from Cornwall was great and had a great crew with him. They did an amazing job and was a pleasure to see their work on my house.
Thank Dave Brown for me too, both his visits were pleasant and fun. I learned a lot from him, and we had great conversations, and without him, I would not have gotten my roof done.
And also a thank you to you too. That long first conversation I had with you at the home show went a long way in my decision in going with an aluminum roof and with your company.
Thanks, and I hope I never have to think about my roof again.

Top 10 Metal Roofing FAQs for Homeowners in Ottawa
Homeowners researching metal roofing in Ottawa often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Ottawa may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.
How long will a metal roof last in Ottawa, ON?
Metal roofs commonly last 40–70+ years, while typical asphalt shingles usually last 15–25 years. Ottawa’s winters bring heavy snowfall and frequent freeze–thaw cycles that increase with climate change—both raise snow-load and ice-dam risks that can shorten roof life if not addressed. Metal roofing sheds snow better, resists recurrent freeze–thaw damage, and tolerates temperature swings and wind-driven precipitation, so it often outperforms asphalt in Ottawa’s conditions. Homeowners choose metal for longevity, lower maintenance, and resistance to heavy snow, ice and wind. Interlock Metal Roofing systems use heavy-gauge aluminium and are backed by a lifetime limited 50-year transferable warranty, designed to provide long-term protection in Ottawa’s snowy, freeze–thaw-prone climate.
How much does it cost to install a metal roof in Ottawa, ON?
Metal roofs in Ottawa typically cost more upfront than asphalt shingles, but final price varies with roof size, slope, complexity (hips, valleys), tear-off, flashing, skylights and labour. Local factors such as heavy winter snowfall—Ottawa commonly receives 220–250 cm annually—and strong freeze–thaw cycles that cause ice dams can increase structural requirements and installation detail, raising costs. Many homeowners compare options by lifetime value: metal roofs cost more initially but resist snow loads, shedding ice and reducing long‑term repair/replacement expenses. A durable system can lower lifecycle costs versus cheaper re‑roof cycles. Interlock Metal Roofing focuses on long‑term ownership value—durability, reduced maintenance and warranty backing—rather than competing solely as the lowest‑cost roofing option.
Should I choose metal roofing or asphalt shingles for my Ottawa home?
Short answer: metal roofing can be worth it in Ottawa if you prioritise durability and long‑term protection.
Lifespan: metal roofs commonly last 40–70+ years versus 15–25 years for asphalt shingles.
Maintenance: metal needs less routine maintenance; shingles require more frequent repairs/replacement and are vulnerable to granule loss.
Durability: metal handles heavy snow loads, freeze–thaw cycles and wind better; asphalt is more prone to ice‑dam damage and accelerated wear in repeated freeze‑thaw conditions. Ottawa averages very high snowfall and pronounced freeze‑thaw seasons, which drive these risks.
Long‑term value: higher upfront cost for metal but lower lifecycle costs and fewer replacements; asphalt is cheaper up front but may cost more over time.
Homeowners who prioritise durability, fewer roof replacements and curb appeal often choose metal. Interlock Metal Roofing systems appeal in Ottawa because they’re engineered for severe winters and offer long‑term warranties and architectural finish options that preserve value.
Are metal roofs noisy when it rains in Ottawa?
This is a common myth: metal roofs aren’t inherently noisy in Ottawa, ON. Modern residential metal roofs installed over solid decking and proper underlayment do not sound like barn roofs. Sound depends on the full roof assembly — insulation, attic space, underlayment and fastening — so a well‑insulated ceiling and correct installation significantly reduce rainfall sound. Installation quality matters: loose panels or improper fixing can increase noise. Properly installed residential metal roofs are typically similar in sound to asphalt, tile or cedar roofs. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, with components chosen to control weather, noise and performance.
How energy-efficient are metal roofs in Ottawa?
Yes — a metal roof can be energy efficient in Ottawa, but results depend on design. Metal roofing often has reflective finishes that reduce solar heat gain in summer, especially with light-coloured, high-albedo coatings. Overall energy performance is set by the complete roof assembly: underlayment, insulation levels, air sealing and attic ventilation determine winter heat loss and ice-dam risk. Ottawa’s cold winters and warm summers mean reflectivity helps in cooling months, while insulation and airtightness drive winter savings. Homeowners researching replacement prioritise energy efficiency to lower operating costs, improve indoor comfort, reduce emissions and boost resale value. When evaluating metal roofing, consider colour, finish and the full roof system. Interlock Metal Roofing systems are designed to support long-term home performance.
How does metal roofing in Ottawa, ON withstand wind, hail, and severe weather?
Ottawa’s climate brings long, snowy winters, freeze–thaw cycles, ice and freezing‑rain events, strong winds and occasional hail—extremes are becoming more frequent and intense. Metal roofing can perform very well in these conditions: it sheds snow, resists water penetration, offers strong wind‑uplift resistance when engineered correctly, and often withstands hail better than asphalt shingles depending on gauge and finish. Performance depends on roofing system design, installation quality and material durability; poor design or installation reduces resilience. Homeowners consider weather resilience to protect the structure, avoid leaks and lower repair costs. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance, but verify product ratings, gauge and installer credentials for Ottawa’s severe freeze‑thaw and ice‑storm environment.
Will a metal roof rust or corrode in Ottawa's wet climate?
Metal roofing performance depends on the type of metal chosen: some metals corrode faster while others resist rust and degradation. Materials such as aluminium and stainless steel offer superior corrosion resistance compared with bare steel, and aluminium performs particularly well in wet or coastal environments because it forms a protective oxide layer. Homeowners should prioritise corrosion resistance to extend roof lifespan, reduce maintenance and avoid leaks or structural damage from rust. In Ottawa’s freeze–thaw cycles and seasonal road‑salt exposure, corrosion‑resistant materials are especially important. Interlock Metal Roofing Systems use aluminium construction designed for strong corrosion resistance and are further protected by the Alunar Coating System, providing extra defence against moisture, salt and environmental pollutants for long‑term durability.
How often should I inspect and maintain my metal roof in Ottawa?
Metal roofing in Ottawa, Ontario is generally low maintenance and very durable, making it a strong choice for local weather. However, no roof is completely maintenance‑free. Homeowners should inspect their roofs periodically—after storms and seasonally—to look for debris, loose fasteners, blocked gutters, damaged flashings, or issues around chimneys, vents and skylights (penetrations). Remove leaves and branches promptly, clear gutters to prevent back‑up, and ensure flashing seals remain intact. Heavy snow, ice dams, hail or wind can cause damage that needs timely repair. With routine checks and minor upkeep, metal roofs offer long life, excellent weather performance and lower ongoing maintenance compared with many other roofing materials.
How does curb appeal affect my home's resale value in Ottawa?
In Ottawa, ON, metal roofing can increase a home’s value. Buyers commonly value durable, low‑maintenance roofs that reduce future costs, and premium roofing materials can enhance curb appeal—important in established neighbourhoods where architectural style matters. A long lifespan also improves buyer confidence, particularly in Ottawa’s climate where snow and freeze–thaw cycles test roofing materials. Interlock Metal Roofing systems offer multiple architectural profiles—slate, cedar shingle, Mediterranean tile, shake and standing seam—available in heavy‑gauge aluminium and solid copper, allowing homeowners to match local styles while gaining performance benefits. Local appraisers and real estate agents can often quantify the premium in specific Ottawa neighbourhoods.
Can I install solar panels on my Interlock Metal Roofing System in Ottawa?
Yes. Interlock Metal Roofing systems are compatible with solar panels when paired with custom solar brackets installed by Interlock Metal Roofing (Ontario) Ltd. Ottawa’s heavy winter snow loads and frequent freeze–thaw cycles can stress roofs and mountings, so choose durable attachment methods and corrosion‑resistant hardware to maintain warranty and performance. Long roof lifespan is important when adding solar—long‑lasting materials reduce the chance you’ll need to remove panels for a reroof. Homeowners in Ottawa should consider future solar plans when replacing a roof; long‑life metal systems like Interlock are often preferred because they’re designed to support solar mounting solutions and minimise future disruption.
