Roof Replacement in Toronto

Roof Replacement in Toronto — When is it the Smart Choice?

Widespread Wear

Granule loss, curled shingles, flat-roof blisters, soft decking—if it’s across large areas, repair dollars won’t go far.

End of Service Life

Most asphalt shingles: 18–25 years. Typical flat roofs (modified bitumen/TPO): 15–25 years with proper maintenance.

Hidden Damage

Recurring leaks often mean compromised underlayment or plywood. Replacement lets us fix the root cause and re-flash properly.

Roof Replacement in Toronto — Material Lifespan (Typical)

These are broad ranges in GTA conditions (ventilation, foot traffic, snow/ice, install quality all matter). Single-ply lifespans vary widely by product and installer.

Toronto Reality Check

Single-ply can need service in 5–10 years when seams are poorly welded, penetrations are detailed badly, or roofs see heavy foot traffic and punctures. 2-ply torch-down is more tolerant of abuse and repairs cleanly, which is why we recommend it for many GTA flat roofs. No roof is truly “permanent”, but well-installed systems with maintenance deliver the longest service life.

Flat Roof Options for Roof Replacement in Toronto

2-Ply Torch-Down (SBS Mod-Bit)

Our default for homes & small commercial. Heat-bonded seams, resilient to abuse, easy to repair, proven in freeze–thaw.

Best for: small/medium roofs, many edges/penetrations.
Pros: durable seams, layered redundancy, clean repairs.
Watchouts: must be installed by certified torchers; hot-works protocols.

TPO (Single-Ply)

Budget choice for large, simple industrial roofs. Big rolls & heat-weld seams keep initial cost down, but details & punctures drive maintenance. Typical life in Toronto: 10–20 years with maintenance.

Best for: very large, open, low-penetration roofs; sites restricting odours.
Pros: reflective surface, wide sheets, lighter weight.
Watchouts: seams/details make or break; puncture/shrink sensitivity; expect more service over 5–10 years if detailing is poor.

EPDM (Single-Ply)

Flexible membrane with long track record. Adhesive seams; protection layer is important against foot traffic. Typical life in Toronto: 10–20 years with maintenance.

Best for: sheltered roofs with low traffic.
Pros: flexible, fewer seams on simple layouts.
Watchouts: black surface runs warm unless white overlay; puncture repair planning needed.

Assembly Matters More Than Membrane

Whether there’s an attic or not, flat roofs over conditioned spaces need the right vapor control, insulation, and venting strategy for Toronto’s climate. We design the whole assembly, not just the top layer.

Roof Replacement in Toronto — FAQ

Do I need a permit for a roof replacement?

Usually not for like-for-like replacement without structural changes. If we replace decking or alter structure/insulation significantly, permits and inspections may apply. We’ll advise during the quote.

How noisy/messy will it be?

It’s an active construction site for a day or two. We protect landscaping, keep walkways clear, and perform a thorough cleanup with magnets before leaving.

Can you work around bad weather?

Yes—we schedule around rain/wind and secure the roof with temporary protection if weather shifts unexpectedly.

Is TPO a good choice in Toronto?

TPO can be economical on very large, simple roofs with few penetrations. For homes and small commercial roofs, we usually recommend 2-ply torch-down mod-bit because it tolerates abuse better and repairs cleanly. We’ll price both options where it makes sense and explain the trade-offs.
