Replacing your roof is a major investment — one that impacts your home’s protection, energy efficiency, and overall value. Whether you’re facing urgent repairs or planning ahead, understanding the costs and benefits of various roofing materials can help you make the best choice for your needs and budget.
In Ontario, asphalt shingles remain a popular choice for many homeowners, but they’re not the only option. Metal, slate, and tile roofs also offer unique advantages. This guide will walk you through the signs it’s time to replace your roof, compare material costs, and help you understand what affects your final price.
When Should You Replace Your Roof in Ontario, Canada?
Roof replacements aren’t always planned — sometimes, nature (or time) makes the decision for you. Here are some common signs:
- The Age of Your Roof: Most asphalt shingles last 20–25 years, although modern premium shingles can offer warranties up to 50 years. If your roof is nearing this age, it’s worth having it inspected.
- Widespread Roof Damage: Look for cracked, curled, or missing shingles. These signs indicate that your roof is no longer effectively protecting your home. Modern asphalt shingles are designed to resist these issues, providing long-lasting protection.
- Leaks and Water Damage: If you notice leaks or water stains on your ceilings, your roof might be compromised. A new asphalt shingle roof, properly installed, will provide a reliable barrier against moisture.
- Moss or Algae Growth: Extensive moss or algae growth can damage shingles and indicate moisture issues. While some growth is natural, persistent or widespread issues can be a sign it’s time to consider a replacement.
- Structural Issues: A sagging roof or other structural problems mean it’s time for a replacement.
Roof Lifespan in Ontario’s Climate
Canadian winters can be brutal, with heavy snow, ice, and temperature extremes. This makes durability a key factor in roofing decisions.- Asphalt Shingles: Affordable and widely used. Today’s high-quality shingles are engineered to last up to 50 years with proper installation and maintenance.
- Metal Roofing: Known for its durability and energy efficiency. Often lasts 40–70 years.
- Slate & Tile Roofing: Premium options with lifespans of 50–100+ years, though they come with a much higher upfront cost and structural weight.
Roof Replacement Costs by Material: What to Expect
The cost of replacing your roof in Ontario can vary widely depending on your home’s size, roof pitch, material choice, and other factors like the removal of old roofing and local labour rates.
While online estimates can offer general guidance, we’ve found they often lead to unrealistic expectations. That’s why we don’t include exact pricing here — instead, we encourage homeowners to schedule a personalized consultation so we can provide an accurate quote based on your specific roof.
Factors that influence cost include:
- The slope (pitch) and complexity of your roof
- Type of material chosen (asphalt shingles, metal, slate, etc.)
- Whether your old roof needs to be removed
- Additional features (chimneys, skylights, valleys)
- Regional labour costs and permit requirements
