Living in Toronto means dealing with four serious seasons. Snow, wind, heat, and rain all pound your roof. If your roof isn’t up to the job, neither is your home.
If you’re a homeowner in Toronto, this guide is for you. Whether you’re fixing a leak, comparing materials, or wondering if it’s time for a full roof replacement — this breaks it down clearly.
Why your Toronto home needs a solid roof
Toronto roofs face things many cities don’t:
-
Freeze-thaw cycles that crack shingles
-
Heavy snow loads that test roof framing
-
Ice dams that force water back under shingles
-
Wind gusts that rip shingles off
Your roof does more than cover your house. It defends your insulation, walls, and foundation.
Toronto also has old housing stock. Many roofs were last redone over 20 years ago. If yours is one of them, your home could be wide open to mold, roof leaks, or insulation problems.
Common damage we see in Toronto homes
-
Rotting wood deck: From trapped moisture under old shingles
-
Cracked flashing: Often around chimneys, skylights, and vents
-
Worn caulking: Especially around metal edging and dormers
-
Nail pops: Which leave holes in shingles and let in water
Signs your roof needs work
You don’t always need to get on a ladder to spot roofing trouble. Look for these signs from inside and outside:
Outside
-
Shingles that are missing, lifted, curled, or cracked
-
Rusted flashing or exposed nails
-
Moss or plant growth (sign of water retention)
-
Gutters filled with granules
-
Sagging or uneven rooflines
Inside
-
Water stains on ceilings or upper walls
-
Damp insulation in attic
-
Drafts or uneven heating
-
A musty smell in the attic or upstairs rooms
You might not see a full leak. But these smaller signs point to trouble up top.
Residential Roofing materials used in Toronto homes
Different homes use different roofing systems — based on structure, style, and budget. In Toronto, these are the most common.
Asphalt shingles
-
Found on most detached and semi-detached homes
-
Come in 3-tab or architectural (dimensional) styles
-
Last 15–25 years
-
Easy to repair, but break down faster under UV and ice
Metal roofing
-
Costs more upfront, but lasts 40–70 years
-
Lightweight and handles snow well
-
Good for steep pitches and modern homes
-
Reflects heat in summer, reducing AC costs
Flat roofs
-
Common on row houses, bungalows, and some additions
-
Use materials like EPDM, TPO, or modified bitumen
-
Require skilled installation
-
Drainage is critical — poor work leads to pooling and fast failure
Cedar shingles
-
Found on some older or custom homes
-
Beautiful but high maintenance
-
Must be treated and installed properly
-
Sensitive to moisture and mold
Slate and synthetic roofs
-
Rare but used on luxury or heritage properties
-
Very long lifespan (50–100+ years)
-
Require strong roof framing
-
Expensive to install and repair
Residential Roof replacement vs repair: Which one is right?
Many homeowners hope for a cheap roof repair. Sometimes that works. But sometimes a full replacement is the only smart option.
When a repair makes sense
-
Damage is limited to one spot
-
Roof is under 10 years old
-
Flashing or sealant is the issue
-
No signs of structural rot
Example: A single corner leaks due to cracked flashing around a vent. A $500 fix solves the issue.
When replacement is smarter
-
You’ve had multiple leaks
-
Shingles are curling or missing across large areas
-
Roof deck feels soft or spongy
-
Energy bills have gone up from insulation loss
-
You plan to sell and want to boost value
Example: Your roof is 20+ years old with repeated issues. A full replacement may cost $12,000 now — but avoids $20,000 in future water damage.

Trim tree branches over roofline

FAQs
How long does a roof last in Toronto?
Most asphalt roofs last 15–20 years here. Metal lasts 40–70 years. Flat roofs: 10–20 years depending on drainage and material. Maintenance extends life.
Is it okay to do roofing in winter?
Yes. Some roofers specialize in cold-weather work. The materials need to be handled differently, but experienced crews handle this without issue.
Do I need a permit to replace my roof in Toronto?
Usually not, unless structural changes are made. Always check with Toronto Building Services if you’re unsure.
What’s the difference between 3-tab and architectural shingles?
3-tab are flat and uniform — cheaper but less durable. Architectural shingles are thicker, layered, and last longer. Most new roofs use architectural.
What kind of warranty should I expect?
Material warranties: 25–50 years (depending on type). Labor warranties: 5–15 years. Ask what’s covered — and get it in writing.
Final thoughts
Don’t wait until your roof fails. Most homeowners see signs years before leaks start. Spot those signs early, compare roofers carefully, and plan ahead. Good roofs don’t happen by accident.
