Markham, ON Metal Roofing Review: Musket Gray Installation and Vent Repair by John and CJ
Markham, ON
Marko P.
Got the roof done a few weeks ago — John and CJ did an excellent job with the install. They went above and beyond helping me fix a vent issue we’d been dealing with. I went with the Musket Gray colour, and I’m really happy with how the final product turned out. Highly recommend!

Top 10 Metal Roofing FAQs for Homeowners in Markham
Homeowners researching metal roofing in Markham 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 Markham 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 Markham, ON?
Metal roofs in Markham typically last 40–70+ years, while asphalt shingles generally have shorter lifespans (often 15–30 years). Markham experiences warm summers and cold, snowy winters with regular freeze–thaw cycles that stress roofing materials and create ice-dam risk, and receives nearly 1,000 mm of annual precipitation including significant snowfall—both factors affect longevity. Metal roofing resists snow loads, shedding snow and handling thermal expansion better than asphalt, so homeowners often choose durable metal systems to minimise maintenance, avoid rot/ice-dam damage and withstand freeze–thaw cycling. Interlock Metal Roofing systems use heavy‑gauge aluminium and come with a lifetime limited 50‑year transferable warranty designed for long‑term protection in Markham’s climate.
How much does it cost to install a metal roof in Markham, ON?
Metal roofs in Markham typically cost more upfront than asphalt shingles. Actual price depends on roof size, slope and complexity, tear‑off, flashing and skylights, plus regional labour and permit costs. Local factors such as heavy winter snow and frequent freeze–thaw cycles — which increase ice dam risk and require stronger underlayments, snow guards and secure fastenings — can raise installation scope and cost. Many homeowners therefore judge roofs by lifetime value rather than initial price: durable metal systems often lower future repair and replacement expenses and can offer better performance under Markham’s seasonal conditions. Interlock Metal Roofing focuses on long‑term ownership value and durability rather than competing as the lowest‑cost option, emphasising systems that reduce lifecycle costs even if the upfront investment is higher.
Should I choose metal roofing or asphalt shingles for my Markham home?
Markham has cold, snowy winters with frequent freeze–thaw cycles and nearly 1,000 mm of annual precipitation—conditions that increase ice-dam risk and wetting of roofing materials.
Lifespan: metal roofs commonly last 40–70+ years; asphalt shingles typically 15–25 years. Maintenance: metal needs infrequent inspections and occasional seal/fastener checks; asphalt requires periodic shingle replacement, granule clean-up and cleaning for algae. Durability: metal sheds snow and resists wind, ice and freeze–thaw damage better; asphalt is more vulnerable to cracking, granule loss and ice-dam uplift. Long-term value: metal’s higher upfront cost often pays back via longer service life and lower replacement/maintenance costs, while asphalt is cheaper initially but may need full replacement sooner.
Homeowners who prioritise durability and long-term protection in Markham often choose metal. Interlock Metal Roofing systems appeal because interlocking panels improve weather-tightness, longevity and architectural curb appeal.
Are metal roofs noisy when it rains in Markham?
This is a common myth. Modern residential metal roofs installed over solid decking do not sound like barn roofs. When fitted with proper underlayment, insulation and a ventilated attic space, metal roofing’s sound level during rain is comparable to shingles or tile. The roof assembly — underlayment type, insulation thickness and whether there’s an attic cavity — has a larger effect on perceived noise than the metal itself. Quality of installation matters: secure fastening, continuous decking and appropriate underlayments reduce vibration and noise. Properly installed residential metal systems typically sound similar to other roofing materials. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes.
How energy-efficient are metal roofs in Markham?
Yes — a metal roof can be energy efficient in Markham. Metal roofing often reflects sunlight, reducing summer heat gain and lowering cooling costs. Overall energy performance depends on the full roof assembly: underlayment, insulation levels and ventilation strongly influence heat loss in winter and heat transfer year‑round. Markham’s four‑season climate means potential benefits vary — reflective finishes help in summer, while adequate insulation and airtight installation matter most in cold months. Homeowners researching roof replacement prioritise energy efficiency to reduce utility bills, improve year‑round comfort, extend roof life and enhance resale value. Interlock Metal Roofing systems are designed to support long‑term home performance by combining reflective coatings, durable materials and compatibility with proper insulation and ventilation.
How does metal roofing in Markham, ON withstand wind, hail, and severe weather?
Markham, ON faces seasonal hazards—summer thunderstorms with wind gusts and hail, and winter storms with heavy snow, freezing rain and ice—so roofs are exposed to wind, hail and heavy precipitation risk.
Metal roofing can perform very well: properly designed and installed metal systems resist high winds, shed heavy rain and snow, and often withstand hail better than many asphalt shingles when using impact‑resistant profiles and coatings. Performance depends on roofing system design (profiles, underlayment, fastenings), installation quality and material durability. Homeowners prioritise weather resilience to reduce repair costs, prevent interior damage and maintain insurance eligibility. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance, but benefits rely on correct product selection, tested impact ratings, manufacturer warranties and professional installation to maximise longevity.
Will a metal roof rust or corrode in Markham's wet climate?
Corrosion and rust resistance are key for metal roofing. Performance depends on the metal—steel, aluminium, copper and coated alloys behave differently—because some metals corrode or rust faster, while others form protective films. Aluminium and copper are naturally more corrosion‑resistant; untreated steel is more prone to rust unless protected. Aluminium performs particularly well in wet or coastal environments because it resists salt and moisture‑induced corrosion. Homeowners should prioritise corrosion resistance to extend roof life, reduce maintenance and repair costs, preserve appearance and protect the building envelope and warranty coverage. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance. Interlock Metal Roofing Systems are protected by the Alunar Coating System for extra protection.
How often should I inspect and maintain my metal roof in Markham?
Metal roofing in Markham, Ontario is generally considered low maintenance due to durable materials and long service life. However, no roof is completely maintenance‑free: routine care prevents small issues from becoming costly. Homeowners should inspect roofs after storms and seasonally—looking for accumulated debris, blocked gutters, loose or damaged flashing, and compromised penetrations (vents, chimneys, skylights). Remove leaves and branches, ensure gutters and downspouts drain freely, and check fasteners and sealants. Weather events (heavy snow, freezing rain, high winds) and seasonal debris can accelerate wear or cause localized damage. Overall, metal roofs remain a durable, low‑maintenance option for Markham homes when paired with periodic inspections and prompt attention to problems.
How does curb appeal affect my home's resale value in Markham?
Metal roofing can increase home value in Markham, ON because buyers value durable, low‑maintenance roofs that reduce future repair costs. Premium roofing materials also boost curb appeal and make a strong first impression on prospective purchasers. A long lifespan and transferable warranties increase buyer confidence in long-term performance and resale value. That said, architectural style matters in neighbourhoods—matching roof profile and colour to surrounding homes helps retain market appeal. Interlock Metal Roofing systems offer multiple architectural profiles, including slate, cedar shingle, Mediterranean tile, shake and standing seam, available in heavy gauge aluminum and solid copper, letting homeowners choose looks that suit local character while providing durable, low‑maintenance protection. This combination can translate into higher offers and quicker sales in Markham’s market.
Can I install solar panels on my Interlock Metal Roofing System in Markham?
As a Markham homeowner comparing roofs: yes — Interlock Metal Roofing Systems are compatible with solar when fitted with custom solar brackets installed by Interlock Metal Roofing (Ontario) Ltd. Markham’s winters bring significant snowfall and frequent freeze–thaw cycles, so choose durable, long‑lived roofing that resists snow loads, ice dams and thermal movement to protect solar mounts and wiring. Roof lifespan matters: panels are long‑term investments, so plan solar when replacing a roof. Long‑lasting materials are often preferred because they reduce future re‑roofing under panels. Interlock systems are solar‑compatible and designed to support approved mounting solutions. Compare expected lifespan and warranties across materials.
