Cost of Asphalt Shingles in Ontario — ROOFNOW™ Guide
Asphalt shingles remain one of the most common roofing materials in Ontario, but their price has risen significantly over the past decade due to oil-based manufacturing, transportation costs, and shorter product lifespans in cold Canadian climates. This guide explains the real cost of asphalt shingles in Ontario and what homeowners should expect when estimating a replacement.

Average Cost of Asphalt Shingles in Ontario
The average cost to replace an asphalt shingle roof in Ontario ranges from $6,500 to $14,000 for a standard-sized home. Larger or more complex roofs may exceed $18,000+.
Typical cost per square foot ranges from $3.50 to $6.50 per sq. ft., including materials, disposal, labour, and basic flashing.
Why Asphalt Roofing Costs Continue to Increase
Asphalt shingle pricing in Ontario has increased steadily due to:
- Rising oil prices — asphalt is petroleum-based.
- Increased manufacturing costs since 2020.
- Frequent warranty changes due to premature granule loss.
- Shorter lifespans in Ontario’s freeze–thaw climate.
- More frequent replacements (10–15 years typical).
Weather is the main cost driver — asphalt absorbs moisture and heat, causing faster deterioration in regions like Ottawa, Barrie, Orillia, North Bay, Sudbury, and the Niagara snow belt.
Material Price Breakdown
Ontario asphalt shingle material prices typically include:
- Architectural shingles: $40–$68 per bundle.
- Starter shingles: $30–$45 per bundle.
- Ridge cap shingles: $45–$70 per bundle.
- Felt or synthetic underlayment: $0.20–$0.60 per sq. ft.
- Ice & water barrier: $70–$100 per roll.
- Nails, vents & flashings: $200–$500 total.
Material quality varies significantly between budget lines and premium options.
Installation & Labour Costs
Labour costs for asphalt shingles vary based on roof complexity:
- Bungalows: Quick installation, lower labour cost.
- Two-storey homes: More equipment, longer hours.
- Hip and valley roofs: Increased cutting and alignment.
- Winter installations: Slower production and safety requirements.
Labour typically represents 50–60% of total asphalt roofing cost.
Lifetime Cost Compared to Metal Roofing
Although asphalt appears cheaper upfront, it has the highest lifetime cost because Ontario homeowners must replace it multiple times. Asphalt shingles provide:
- No energy savings
- 10–15 year lifespan in many Ontario climates
- Higher winter failure rate in freeze–thaw cycles
- Frequent granule loss leading to early deterioration
Over 50 years, many homes will require 3–5 asphalt replacements, making it more expensive long-term than a single metal roofing system.
Asphalt Cost FAQ for Ontario Homeowners
Why do asphalt shingles fail faster in Ontario?
Extreme freeze–thaw cycles and moisture absorption cause cracking, curling, and granule loss.
Can asphalt be installed in winter?
It can, but cold temperatures may prevent proper sealing and reduce durability.
Does asphalt save energy?
No. Asphalt shingles provide zero energy savings and often increase attic heat buildup.
How long does an asphalt roof last?
Most Ontario homes get 10–15 years before major deterioration appears.
