Ottawa, ON Metal Roofing Review: Why We Chose Interlock for a Cooler, Quieter, One-Day Roof Installation
Ottawa, ON
Nina and RĂ©gent G.
We looked at different alternatives to re-roof our house, and we chose the Interlock roofing system because it represented the best value available. Barry Brinson answered all our questions when we met him on the Saturday afternoon of a long weekend.
Shortly after the materials were delivered, John Caverley arrived with his crew and promptly proceeded to install the roof. He and his crew were thoroughly professional, and their use of safety equipment was reassuring. The team was well-integrated; they showed that they knew what they were doing, and all proceeded without a hitch. They worked tirelessly and were done in one day.
When they left, there were no nails, scrap or cigarette butts behind, only a brand-new roof that was the envy of the neighbourhood. After a few weeks, we can say that the roof is quiet, even with heavy rain, and the upstairs rooms are cooler on a <a class="wpil_keyword_link" title="hot" href="” data-wpil-keyword-link=”linked”>hot day than was the case in the past.
We would not hesitate to recommend an Interlock roof for its value and looks. Barry and John went out of their way to make it all happen to our complete satisfaction.

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; asphalt shingles typically last 15–25 years, so metal is a long‑term choice. Ottawa’s climate — heavy winter snowfall (around 224 cm annually) and frequent freeze–thaw cycles — puts extra stress on roofs through snow loads, ice-damming and repeated expansion/contraction that can shorten weaker systems. Metal roofing resists snow weight, sheds ice and tolerates thermal cycling better than asphalt, so homeowners choose durable systems to reduce maintenance, avoid premature replacement, and retain resale value. Wind, occasional hail and seasonal rain are additional local considerations, but heavy‑gauge metal coupled with proper installation mitigates those risks. Interlock Metal Roofing systems use heavy‑gauge aluminium and include a lifetime limited 50‑year transferable warranty designed for long‑term protection.
How much does it cost to install a metal roof in Ottawa, ON?
Metal roofs in Ottawa generally cost more upfront than asphalt shingles. Exact price depends on roof area, pitch, complexity (dormers, valleys), tear‑off and disposal, flashing and skylight work, and local labour and permit costs. Winter conditions, access, and nearby supply prices can influence final pricing in the Ottawa area. Many homeowners evaluate roofing choices by lifetime value—metal roofs have higher initial costs but longer service lives, lower maintenance and reduced repair or replacement frequency, which can lower total ownership cost over decades. Durable systems also resist ice damming and corrosion better, helping reduce future repairs. Interlock Metal Roofing emphasises long‑term ownership value: we prioritise durable assemblies and workmanship rather than trying to be the lowest‑cost option, because the best value often comes from reduced lifetime expense and greater peace of mind.
Should I choose metal roofing or asphalt shingles for my Ottawa home?
Metal roofing can be worth it in Ottawa if you prioritise durability and long‑term protection. Ottawa has cold, snowy winters with heavy annual snowfall and frequent freeze–thaw cycles that stress roofing materials, plus occasional hail and strong winds.
Lifespan: metal typically lasts 40–70+ years; asphalt shingles 15–25 years in this climate. Maintenance: metal needs less routine repair (clearing snow/ice, checking fasteners); asphalt requires more frequent inspection, patching and replacement. Durability: metal resists snow loads, freeze–thaw damage and wind better; asphalt can curl, lose granules and be vulnerable to ice dams and hail. Long‑term value: higher upfront cost for metal but lower life‑cycle costs and often better resale value.
Homeowners wanting maximum longevity and architectural curb appeal often choose metal. Interlock Metal Roofing systems appeal here for proven long‑term performance, low maintenance and clean, lasting aesthetic.
Are metal roofs noisy when it rains in Ottawa?
This is a common myth: modern residential metal roofs installed over solid decking do not sound like barn roofs. When fitted as a complete roofing assembly—solid sheathing, underlayment, insulation and an attic or ceiling cavity—metal roofing’s noise during rain is comparable to shingles or tiles. Insulation, ventilation and the overall roof assembly absorb and dampen impact noise; a poorly installed roof or missing underlayment can increase sound. Quality of installation, fastening method and attic treatments matter more than the metal itself. Properly installed residential metal roofs typically produce similar rainfall sound levels to other roofing materials. Interlock Metal Roofing systems are supplied and installed as complete residential roofing systems designed to meet these performance expectations.
How energy-efficient are metal roofs in Ottawa?
Yes — in Ottawa, a metal roof can be energy efficient. Metal roofing reflects sunlight, reducing heat gain in summer, and when combined with proper roof assembly, insulation and ventilation it can improve overall energy performance. Ottawa’s cold winters and warm summers mean benefits vary: high reflectivity helps in summer, while good insulation and ventilation prevent heat loss in winter. Homeowners researching roof replacement often prioritise energy efficiency to lower heating and cooling costs, improve year‑round comfort, and increase long‑term resale value and sustainability. Proper installation and attic detailing are key to realising savings. Choosing an appropriate colour and finish for Ottawa’s climate can further improve solar reflectance and snow‑shedding. 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?
FAQ — How does metal roofing perform in Ottawa, ON’s severe weather?
Ottawa has cold, snowy winters with freezing rain, plus summer thunderstorms, gusty winds and occasional hail, and climate trends show warmer, wetter, more variable weather.
Metal roofs resist high winds when mechanically fastened or interlocked, shed snow and ice effectively, and may dent from very large hail depending on gauge and finish. Performance depends on roofing system design (profile, fastening, underlayment), installation quality, and material durability (gauge, coating, warranty). Homeowners weigh weather resilience to reduce leaks, ice‑damming, storm damage and long‑term replacement costs. Interlock Metal Roofing systems are engineered for durability, enhanced hail protection and tested wind resistance, making them a strong choice for Ottawa’s mixed severe‑weather risks.
Will a metal roof rust or corrode in Ottawa's wet climate?
Corrosion and rust resistance in Ottawa, ON depend largely on the metal used. Steel, aluminium and other alloys perform differently: some metals are more prone to rust, while aluminium and properly coated alloys resist corrosion better. Aluminium performs particularly well in wet or coastal environments because it naturally forms a protective oxide layer and does not rust like iron-based metals. Homeowners should consider corrosion resistance to extend roof lifespan, reduce maintenance and avoid leaks or structural issues from material degradation. Interlock Metal Roofing systems use aluminium construction engineered for strong corrosion resistance and are further protected by the Alunar Coating System for extra defence against moisture and atmospheric exposure, making them a durable choice for Ottawa’s climate.
How often should I inspect and maintain my metal roof in Ottawa?
In Ottawa, Ontario, metal roofing is generally considered a low‑maintenance, durable option. That said, no roof is completely maintenance‑free. Homeowners should inspect roofs periodically—at least seasonally and after major storms—to spot issues early. Check for accumulated debris, clear gutters, and confirm flashing and roof‑penetration seals (vents, chimneys, skylights) are intact and fasteners are secure. Heavy snow, ice and wind‑driven debris or falling branches can affect performance and accelerate wear, so remove obstructions safely or hire a professional. With proper seasonal checks and prompt attention to problems, a metal roof will provide long service with fewer upkeep demands than many other roof types.
How does curb appeal affect my home's resale value in Ottawa?
Yes. In Ottawa, metal roofing can increase a home’s resale appeal and perceived value. Buyers particularly value durable, low‑maintenance roofs that reduce future repair concerns. Premium roofing materials and attractive profiles enhance curb appeal and help a house stand out in local listings. The long lifespan of metal roofing also improves buyer confidence, as warranties and proven longevity reduce perceived risk. Architectural style matters in Ottawa neighbourhoods: a roof should suit the home and street character to maximise value. 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, letting you match style while delivering performance. Local appraisal and market conditions ultimately determine exact price uplift.
Can I install solar panels on my Interlock Metal Roofing System in Ottawa?
Yes — Interlock Metal Roofing systems are compatible with solar panels when fitted with Interlock Metal Roofing (Ontario) Ltd.’s custom solar brackets. In Ottawa, heavy winter snow loads and frequent freeze–thaw swings (which increase ice‑dam risk) are key local factors that affect roof and mount performance. Because solar adds weight and attachment points, roof lifespan matters — long‑lasting materials (like Interlock’s metal systems) are often preferred. If you plan to add panels later, choose a durable roof now and discuss future solar with your roofer so mounts and warranties align. Interlock systems are designed to support solar mounting solutions and can simplify installation compared with shorter‑lived roofing options.
