Asphalt is the right choice for most GTA homeowners — $9,500–$14,500 for a 2,000 sq ft home, 25–30 year life, fully recyclable, fast install. Metal is the right choice for homeowners staying 20+ years who want to roof once and never again — $18,000–$32,000, 40–70 year life, premium curb appeal. Cedar, slate, and synthetic premium are niche choices for heritage and luxury homes. The wrong choice isn't between metal and asphalt; it's between the right material for your specific situation and the wrong one. Here's how to decide.
Asphalt — the GTA default for good reason
About 85% of GTA homes have asphalt shingle roofs. There's a reason: it works, it's affordable, it's easy to repair, and it's been refined over 100+ years. Modern architectural asphalt is far better than 3-tab — thicker, better wind resistance, better UV stabilization, longer warranties.
Pros: lower upfront cost, fast install, familiar to every contractor, easy spot repair, full insurance coverage, recyclable, wide style/colour selection
Cons: 25–30 year life means you'll replace at least once during ownership, granule loss visible toward end-of-life, less hail-resistant than metal
Best for: homeowners under 60 staying 5–20 years, budget-conscious replacements, homes where you might sell within 15 years
Metal — the long-game choice
Standing-seam metal is the second most common premium upgrade after architectural asphalt. The visual is more modern, the lifetime is dramatically longer, and the maintenance is nearly zero — but the upfront cost is 2–3× and the install crew needs different skills.
Pros: 40–70 year lifetime (often outlasts ownership), excellent wind resistance, premium curb appeal, low maintenance, high snow-shed (less ice dam risk), fully recyclable at end-of-life
Cons: 2–3× upfront cost, louder during heavy rain (mitigated by underlayment), potential for thermal expansion noise, some architectural styles don't suit it, harder to find experienced installers
Best for: homeowners staying 20+ years, heritage homes where authenticity matters, modern architectural builds, properties in high-wind exposure areas
The 50-year lifetime cost comparison
Most homeowners only think upfront cost. Lifetime cost is the more honest metric. On a 2,000 sq ft GTA home over 50 years:
Asphalt scenario: install $11,500 → re-roof in year 25 at projected $18,500 → re-roof in year 50 at projected $29,500 = ~$30,000 spent (year 0 dollars), but 2-3 disruption events
Metal scenario: install $24,000 → still on original roof at year 50 = $24,000 spent (year 0 dollars), 1 disruption event
Metal wins lifetime IF you stay long enough to capture the second avoided cycle
Asphalt wins NPV (net present value) for shorter ownership horizons
GTA climate factors
Both materials handle GTA freeze-thaw cycles well when properly installed. Specific climate considerations:
Snow load: metal sheds snow faster, reducing ice dam risk and structural stress
Freeze-thaw: asphalt is fine if shingle quality is right; cheap 3-tab is not
Heat: metal stays cooler in summer (reflective), saving on AC; modern asphalt has reflective options too
Hail: metal dents (cosmetic) but rarely fails; asphalt loses granules and can fail catastrophically in severe hail
Wind: standing-seam metal is rated for higher winds than even premium asphalt
When to pick asphalt anyway
Even with metal's longer lifetime, asphalt is the right choice in these specific scenarios:
You're considering selling within 10 years — you won't recoup the metal premium
Your roof has high architectural complexity (many small dormers, valleys) — metal install cost scales fast
Your neighbourhood has visual continuity in a Heritage Conservation District where metal would be inappropriate
You want simple, fast, recoverable repairs — asphalt is easier to spot-fix
Your budget cannot stretch to metal — a quality architectural asphalt will outperform a poorly-installed cheap metal
When to pick metal
Metal is the right choice when these factors line up:
You're staying 20+ years (or this is a forever home)
Your home is in a high-wind exposure area (lakefront, hilltop, open lot)
You're tired of dealing with shingle issues every 5–10 years
You want maximum curb appeal differentiation
You have a moderate slope architecture that suits standing-seam visually
You can finance the upfront cost without strain
Common questions.
Direct answers, no filler.
Is metal really louder than asphalt in the rain?
Slightly, but modern installs include sound-dampening underlayment that reduces the difference to barely perceptible. The exception is barn-style ribbed metal directly over open framing — that's loud. Standing-seam over a properly insulated attic is comparable to asphalt.
Does metal expand and contract noticeably?
Yes — metal expands and contracts with temperature, which is why standing-seam clips are designed to allow movement. Properly installed metal is silent. Improperly installed metal can pop or click in temperature swings. Hire someone who has installed metal before.
Will metal rust in the GTA?
Modern metal roofing has 50+ year corrosion warranties on coating systems. Lakefront properties in Mississauga, Burlington, Etobicoke, and Pickering should specify aluminum (not galvanized steel) for salt-air longevity.
Can I install metal over my existing asphalt?
Sometimes, but we don't recommend it. Tear-off lets us inspect and repair decking, install proper underlayment, and ensure the metal goes on a clean surface. Going over existing shingles often voids the metal manufacturer's warranty.
Is metal more 'green' than asphalt?
Both are recyclable. Metal lasts 2–3× as long, so total resource use is lower. Modern architectural asphalt also has cool-roof reflective options. Neither is dramatically better than the other for environmental impact when comparing premium grades.
What's the warranty difference?
Premium architectural asphalt: 30-year limited to lifetime manufacturer warranty + 25-year workmanship. Standing-seam metal: 40–50 year coating + lifetime substrate + 25-year workmanship. Metal warranties typically transfer to next owner; asphalt warranties often pro-rate.
Does metal increase home value more than asphalt?
On premium homes (>$1.5M), yes — metal signals quality and reduces buyer concerns about future replacement. On mid-market homes, the resale lift often doesn't recover the upfront premium. The honest answer: metal pays back through use, not resale.
Can you do both — premium asphalt with metal accents?
Yes, hybrid roofs are common: standing-seam metal on bay windows, dormers, or porches with architectural asphalt on main slopes. Often the best of both — visual interest without full metal cost.
