We don’t just nail down panels. We engineer, manufacture, and install permanent steel systems that protect your home, elevate curb appeal, and increase property equity. If you plan to stay in your home for the long haul, this is the last roof you will ever need.
The Temporary Roof Trap: Why Asphalt Fails in Ontario
The traditional roofing industry relies on planned obsolescence. While manufacturers aggressively market “30-year” or “lifetime” architectural shingles, the reality of the Ontario climate tells a completely different story.
Most homeowners don’t realize that in regions stretching from Toronto to the Golden Horseshoe, a standard asphalt roof realistically fails in just 12 to 18 years. This rapid degradation isn’t bad luck—it’s a physical certainty driven by our volatile weather:
- Freeze-Thaw Expansion Damage: Ontario experiences rapid, extreme temperature swings. Snow melts during the day, seeps into the porous backing of asphalt shingles, and freezes at night. This microscopic ice expansion literally tears shingles apart from the inside out, severely compromising your attic’s vapor management.
- Destructive Ice Storms & Dams: Poorly ventilated asphalt roofs trap attic heat, melting base snow which then refreezes at the eaves. This creates massive ice dams that physically pry shingles apart. Our metal profiles, by contrast, rely on structural ice dam mitigation to shed moisture long before it pools and freezes.
- Lake-Effect Snow & Moisture: Heavy, wet lake-effect snow creates immense, prolonged static weight and moisture saturation that accelerates the rot of traditional, porous roofing materials.
- 100 km/h Wind Gusts: Severe storm fronts rolling off the Great Lakes easily catch the compromised, dried-out edges of aging shingles, tearing them completely off the roof deck.
The Financial Reality: Replacing an asphalt roof is a recurring liability. When you calculate the math over a 30-to-40-year horizon, staying with asphalt means funding three separate, messy, and increasingly expensive roof replacements. Metal roofing permanently solves this fundamental flaw in homeownership.
What is an Asphalt to Metal Roof Conversion?
Metal roof replacement is the highly specialized process of upgrading a home’s primary weather defense from temporary petroleum-based materials to permanent, high-gauge steel roofing (typically 24- to 26-gauge, depending on your chosen profile). At Canadian Metal Roof Manufacturing Ltd., we exclusively perform residential metal roof replacements and lead the industry in metal re-roofing Ontario properties. We aren’t general contractors; we are specialized manufacturers and building science experts.
An asphalt-to-metal conversion is a precision engineering project that exceeds Ontario Building Code standards. Depending on your home’s structural architecture, we utilize two primary installation methods:
Full Tear-Off vs. The Engineered Strapping System
When necessary, we perform a total tear-off. We strip the old asphalt down to bare wood, inspect the structural deck, repair any compromised plywood, and apply a high-performance synthetic underlayment.
However, if your current roof has a single, flat layer of shingles and a healthy deck, we utilize an advanced timber strapping system. By securing a framework of 1×4 timber horizontally and vertically across the roof deck, we create a highly effective thermal break. Leveraging modern ventilation science, this continuous air gap optimizes attic airflow and vapor management. It allows the roof to breathe, eliminates condensation, and dramatically improves your home’s energy efficiency.
Why Serious Ontario Homeowners Switch to Metal
- 50+ Year Proven Lifespan: While asphalt fails in a decade, our premium steel systems are engineered to last a half-century or more. Backed by our 50-year transferable warranty, your roofing problem is solved for good.
- Architectural Curb Appeal & Color Retention: Metal is no longer just for barns. From the sleek, modern lines of our flagship Royal Panel profile to the classic versatility of the Indigo Panel, we manufacture styles that elevate high-end residential architecture. We utilize high-performance coatings—with premium options available, including PVDF/Kynar-grade on select finishes, where applicable—formulated to resist UV fading and chalking for decades.
- Unmatched Energy Efficiency: Traditional shingles absorb summer heat, turning your attic into an oven. Our metal roofing profiles bounce radiant heat away, significantly lowering your summer cooling costs.
- Superior Resale Value: A metal roof is a massive asset. Prospective buyers view a permanent roof as a premium upgrade that eliminates their future replacement liability. You recoup a high percentage of the installation cost directly into your home’s equity.
- Wind Uplift & Fire Performance: Our interlocking panel systems are engineered for high-wind uplift resistance and are meticulously installed to meet or exceed strict Ontario building requirements. Plus, steel provides Class A fire resistance.

Our Precision Installation Process
The performance of a metal roof is entirely dictated by the precision of its installation. Generic roofing crews used to nailing down asphalt simply cannot properly install architectural steel.
Canadian Metal Roof Manufacturing Ltd. relies strictly on highly trained, factory-certified installation technicians. We never use subcontractors. Our five-step conversion process guarantees uncompromising quality.
Step 1: The Engineering Consultation
We conduct a rigorous on-site assessment, taking precise measurements, evaluating attic airflow, and reviewing panel profiles to match your home’s architecture. We provide a firm, detailed quote—no rough estimates, no hidden fees.
Step 2: Pre-Installation Protection
Before a single panel is cut, we protect your property with specialized tarps and scaffolding to safeguard your landscaping, gardens, and driveway.
Step 3: Advanced Underlayment and Strapping
We secure the foundation by installing a high-performance synthetic underlayment. Then, our crews anchor the custom strapping framework directly into your roof trusses for perfect panel alignment and structural rigidity.
Step 4: Custom Panel & Flashing Integration
Our factory-trained crews systematically install your chosen profile. We engineer the installation to gracefully handle natural thermal expansion and contraction across the seasons, preventing panel warping. We pay meticulous attention to the most vulnerable points—valleys, dormers, chimneys, and skylights—using custom-bent, color-matched flashings for an impenetrable seal.
Step 5: Magnetic Cleanup & Certification
Following a flawless installation, we conduct a magnetic sweep of your entire property to ensure zero rogue fasteners are left behind. We walk you through the finished project and hand over your 50-year transferable warranty certificate.
Metal Roof Replacement Cost in Ontario
It’s the most common question we receive: How much does it cost to replace shingles with a metal roof?
We believe in total transparency. Because metal roofing utilizes premium-grade steel, advanced coating systems, and highly specialized labor, the initial capital investment is higher than nailing down temporary asphalt. In today’s market, you can expect a metal roof replacement to cost two to three times the upfront price of an asphalt roof. Most asphalt roof replacements in Ontario range between $8,000 and $18,000 depending on size and complexity, while premium metal systems reflect a higher initial investment due to material grade and installation precision.
Your exact investment depends on:
- Total Square Footage & Complexity: Steep pitches, multiple dormers, complex valleys, and skylights require intricate, custom-cut flashing work.
- Panel Profile: The system you select—whether a classic exposed fastener or a premium hidden-fastener profile—dictates the material and labor requirements.3
The Long-Term ROI Equation
If you are flipping a house next year, asphalt makes sense. But if you plan to stay in your home for a decade or more, metal is the only financially sound choice. By investing in a single metal roof today, you eliminate the compounding costs of future inflation, labor hikes, and multiple disposal fees.

Common Questions (Asphalt to Metal Conversion)
Can you install a metal roof directly over existing asphalt shingles?
Yes. If the current roof has a single layer of shingles and a structurally sound deck, we install an engineered strapping system directly over the old roof. This creates a highly effective thermal break and keeps tons of toxic asphalt out of local landfills.
Is a metal roof noisy in the rain or hail?
No. When installed correctly over an existing solid roof deck, high-performance synthetic underlayment, and a properly insulated attic, a metal roof is acoustically indistinguishable from an asphalt roof during heavy rain or hail.
Will a metal roof rust in the Ontario climate?
No. Our panels are manufactured using high-grade steel substrates engineered specifically for the Canadian climate. Combined with advanced, industry-leading paint systems, these panels are chemically formulated to resist rust, fading, and corrosion for decades.
Do I need snow guards in Ontario?
Yes. Because metal sheds snow effortlessly, heavy winter accumulation can slide off in a dangerous sheet. We calculate local snow load requirements and install heavy-duty, color-matched snow guards to hold the snow in place, allowing it to melt safely and gradually.
