How Long Can a Roof Last? The Answer Will Surprise You!

When was the last time you checked your roof? Most homeowners don’t think about it until a leak appears. But here’s the truth: roofs don’t last forever.

Depending on the material, installation, and climate, a roof can last anywhere from 15 to 100 years. And if you live in Ontario, harsh winters and hot summers can shorten that lifespan.

At All Stars Roofing Inc., we’ve replaced and repaired thousands of roofs across Ontario, and one thing is clear: choosing the right material and contractor makes all the difference. In this guide, you’ll learn:

• Roof lifespan by material

• Factors that affect roof life in Ontario

• Signs your roof may be failing

• Proven ways to extend your roof’s life

Average Roof Lifespan by Material

extend roof life Roofing Material	Average Lifespan	Best For
3-Tab Asphalt Shingles	15–25 years	Budget-friendly installs
Architectural Shingles	25–35 years	Mid-range durability
Metal Roofing	40–70 years	Harsh climates, snow resistance
Wood/Cedar Shakes	20–40 years	Rustic look, high maintenance
Clay/Concrete Tiles	50–100 years	Warm/dry climates (rare in Ontario)
Slate Roofing	75–150 years	Premium, heritage homes

In Ontario, asphalt shingles are the most common choice. However, at All Stars Roofing Inc., we’ve seen a steady rise in homeowners choosing metal roofing in 2025 for its unmatched durability and energy efficiency.

Key Factors That Affect Roof Life

• Ontario’s Climate Freeze-thaw cycles, heavy snow, and summer storms shorten a roof’s life.

• Installation Quality Even premium shingles fail early if installed poorly. That’s why All Stars Roofing Inc. trains every crew to follow best practices for long-term performance.

• Ventilation and Insulation Proper attic airflow prevents heat and moisture damage.

• Maintenance Neglected repairs cut years off a roof’s lifespan.

• Material Choice The type of roof you choose directly determines its longevity.

Signs Your Roof May Be Failing

• Curling, cracked, or missing shingles

• Granules clogging gutters

• Water stains inside your home
