Ottawa Metal Roofing Review: Interlock Black Slate Roof Installation in Hunt Club / Conroy Area
Ottawa, ON
Anna and Randy
My wife and I are very impressed with the looks of the INTERLOCK black slate roofing system that was just installed on our home in the Huntclub Road / Conroy Road area in Ottawa.
The crew that installed the roofing material during the 3rd and 4th weeks of January 2019 worked through and around temperatures between +.5°C to -25.°C, two weather events that dropped 46 cm of snow and 6 mm of rain and freezing rain plus the occasional days of lite snow flurries.
The lead installer told me that a normal installation for the size of our roof could take 2 to 3 days in the spring, summer and fall but with the unpredictable weather doing winter jobs, it can take longer as some days with the extreme cold and dumps of snow it’s just too dangerous to work outside let alone on a roof.
The three-person crew was very courteous and answered any and all questions my wife and I had during the installation process, and they made sure the work site was clean and tidy before leaving for home.

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 roofs typically have shorter lifespans (often 15–25 years) and need more frequent replacement. Ottawa’s long, cold, snowy winters with substantial annual snowfall, plus frequent freeze–thaw cycles and warm summers, increase snow loads, ice-damming risk and thermal cycling on roofs—conditions that shorten less-durable coverings.Metal roofing resists moisture, rot and freeze–thaw damage better than asphalt, sheds snow when properly detailed, and holds up well to wind and occasional hail—reasons homeowners choose durable metal systems for lower maintenance and longer service life. Climate projections for the National Capital Region also highlight persistent freeze–thaw activity, reinforcing the value of long-lasting materials. Interlock Metal Roofing systems use heavy-gauge aluminium and include a lifetime limited 50-year transferable warranty for long-term protection.
How much does it cost to install a metal roof in Ottawa, ON?
Metal roofs in Ottawa usually cost more up front than asphalt shingles; final price depends on roof area, slope, complexity, tear‑off, flashing, skylights and labour. Local factors such as heavy winter snowfall and prolonged cold seasons increase structural and fastening requirements, and frequent freeze–thaw cycles/ice‑dam risk make quality underlay and ventilation more important—both can raise installation cost and labour time in Ottawa. Many homeowners therefore compare options by lifetime value rather than initial price: thicker metal, better coatings and proper installation reduce future repair and replacement costs. Interlock Metal Roofing positions its systems for long‑term ownership value and durability rather than competing as a low‑cost roofing option.
Should I choose metal roofing or asphalt shingles for my Ottawa home?
Short answer: often yes — for homeowners in Ottawa who prioritise durability and long-term protection, metal roofing is worth the higher upfront cost.
Lifespan: metal typically lasts 40–70+ years versus 15–30 years for asphalt shingles. Maintenance: metal needs less routine repair and resists ice-damming and shingle blow-off; asphalt needs more frequent patching and replacement. Durability: metal sheds heavy snow loads and tolerates repeated freeze–thaw cycles better, while shingles can degrade faster under repeated freezing, thawing and heavy snowfall in Ottawa. Long-term value: higher upfront cost for metal often yields lower life-cycle cost and stronger resale appeal.
Not always best for every budget, but homeowners seeking long-term performance and architectural curb appeal often choose Interlock Metal Roofing systems for their durability, finish options and lasting value.
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 — they’re fixed to a continuous substrate, which greatly reduces noise. Sound levels depend on insulation, attic space, underlayment and the overall roof assembly; adding insulation, sound-deadening underlayments and an air gap will further reduce rainfall noise. Installation quality matters: tight fastenings, sealed penetrations and manufacturer-specified assemblies prevent rattling. Properly installed residential metal roofs are typically similar in sound to other roofing materials during rain. Interlock Metal Roofing systems are installed as complete roofing systems designed specifically for residential homes. In Ottawa, ON, this means you can expect noise levels comparable to asphalt shingle or tile roofs when correctly installed.
How energy-efficient are metal roofs in Ottawa?
In Ottawa, a metal roof can improve energy efficiency because its standing‑seam surfaces and reflective coatings reduce heat gain by reflecting sunlight during warm months. Overall performance depends on the complete roof assembly: underlayment, insulation levels and attic ventilation all influence heat flow and moisture control. Ottawa’s cold winters and warm summers mean benefits vary — reflective coatings help cooling in summer, while proper insulation and air sealing are essential to limit winter heat loss. Homeowners replacing roofs often prioritise energy efficiency to lower utility bills, increase comfort, reduce condensation risk, and boost resale value. When assessing options, consider whole‑roof performance, not just the material. 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 roofs face heavy snow, ice storms, freeze–thaw cycles, strong winds, and occasional hail and severe thunderstorms. Metal roofing performs well in wind (low uplift when interlocked and fastened correctly), sheds snow and water fast to reduce ice-dam risk, and resists hail better than many asphalt shingles when made from durable gauge steel or aluminium. Real-world performance depends on roofing system design, installation quality, and material durability (coating, thickness, fasteners). Homeowners prioritise weather resilience to protect structure, lower repair costs, maintain insulation performance, and meet insurance requirements. Interlock Metal Roofing systems are engineered for durability, enhanced hail protection and tested wind resistance, but results still rely on correct design and professional installation.
Will a metal roof rust or corrode in Ottawa's wet climate?
Corrosion and rust resistance are key when choosing metal roofing in Ottawa, ON. Metal roofing performance depends on the type of metal — some, like steel, can corrode if not properly coated, while others are inherently more resistant. Aluminum performs particularly well in wet or coastal environments because it forms a protective oxide layer that limits corrosion. Homeowners should prioritise corrosion resistance to extend roof life, reduce maintenance and repair costs, preserve appearance, and protect insulation and structure from water damage. Interlock Metal Roofing systems use aluminum construction engineered for strong corrosion resistance and are further protected by the Alunar Coating System for extra protection against the elements. Choosing corrosion-resistant materials helps ensure long-term performance and can improve warranty outcomes and resale value.
How often should I inspect and maintain my metal roof in Ottawa?
Metal roofing in Ottawa, Ontario is generally low maintenance: durable, corrosion‑resistant and long‑lasting compared with many materials. However, no roof is completely maintenance‑free. Homeowners should inspect roofs periodically—at least twice a year and after major storms—to look for loose fasteners, damaged panels or compromised sealants. Check and clear debris from roof surfaces and valleys, keep gutters and downspouts free‑flowing, and inspect flashing and roof penetrations (vents, chimneys, skylights) for secure seals. Seasonal debris, heavy snow, ice and wind‑driven branches can cause damage or accelerate wear. With routine visual checks and prompt attention to issues, metal roofs remain a highly durable, low‑maintenance choice for Ottawa’s climate.
How does curb appeal affect my home's resale value in Ottawa?
Yes — in Ottawa, ON, quality metal roofing can increase home value. Buyers here favour durable, low‑maintenance roofs that cut future repair costs and insurance concerns. Premium roofing materials also enhance curb appeal, particularly where neighbourhood architectural style matters: a roof that fits local character attracts more buyers. The long lifespan and proven performance of metal roofs boost buyer confidence and can support a higher asking price. 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, providing options to suit both traditional and contemporary homes. Actual value uplift depends on local comparables, installation quality and overall home condition.
Can I install solar panels on my Interlock Metal Roofing System in Ottawa?
Yes. Interlock Metal Roofing Systems are compatible with solar installations when custom solar brackets are fitted by Interlock Metal Roofing (Ontario) Ltd. In Ottawa, heavy winter snowloads and frequent freeze–thaw/ice‑dam and freezing‑rain conditions can increase stress and water‑ingress risk, so roof longevity matters when adding panels. Consider future solar plans when replacing a roof: longer‑lived materials (like Interlock metal) minimise the chance of removing panels for reroofing. Interlock systems are solar‑compatible and designed to support approved mounting solutions, and properly installed brackets and flashings help withstand Ottawa’s winter conditions.
