Asphalt shingles are one of the most widely used roofing materials across Canada, including Vancouver. Their affordability and ease of installation make them a popular choice, but are they the best option for your home? Understanding the pros and cons of asphalt shingle roofing in Vancouver will help you make an informed decision. This guide explores cost, durability, maintenance, and environmental impact to help you choose the right roofing solution.
Why Asphalt Shingles Are Popular in Vancouver
Vancouver’s wet climate creates unique challenges for homeowners. Constant rain, wind, and occasional snowfall require a roofing material that can withstand moisture-related issues like mould and rot. Asphalt shingle roofing remains a top choice due to its affordability, flexibility, and decent weather resistance. However, as with any roofing material, there are both benefits and drawbacks to consider.
The Pros of Asphalt Shingle Roofing in Vancouver
1. Affordable Roofing Solution
One of the biggest advantages of asphalt shingle roofing is its cost-effectiveness. Compared to other roofing materials like metal or slate, asphalt shingles are much more budget-friendly. The cost of installation is also lower because the material is lightweight and easy to work with, reducing labour expenses.
A new asphalt shingle roof can cost anywhere from $5,000 to $15,000 for an average-sized home in Vancouver, depending on factors such as shingle quality, labour, and roof complexity. In comparison, a metal roof can cost between $15,000 and $30,000, while slate or cedar shakes can be even higher.
2. Wide Range of Styles and Colours
Asphalt shingles come in a variety of textures, colours, and designs, making it easy to find an option that suits your home’s aesthetic. Whether you prefer a modern, sleek look or something more traditional, there’s an asphalt shingle to match your vision.
Additionally, architectural shingles (also called dimensional shingles) offer a more premium look than standard three-tab shingles while still being more affordable than luxury roofing materials. These can mimic the look of wood or slate without the high cost or maintenance.
3. Simple Installation and Repairs
Compared to other roofing materials, asphalt shingle roofing is easy to install. This means a faster, less expensive installation process. If a few shingles are damaged due to weather or wear, individual shingles can be replaced without needing a full roof replacement, keeping long-term maintenance costs manageable.
Most asphalt shingle roofs can be installed within 1-3 days, depending on the size and complexity of the project. This is significantly faster than materials like tile or metal, which may take a week or longer.
4. Good Weather Resistance
High-quality asphalt shingles are designed to withstand Canada’s varying weather conditions. Many shingles are built with resistance to wind, rain, and even moderate hail. Some premium shingles are engineered to resist impact and UV exposure, which is particularly useful for Vancouver’s mix of wet and sunny seasons.
Modern asphalt shingles are often rated for wind speeds of up to 209 km/h (130 mph), which is essential for homeowners in coastal areas or places prone to strong winds.
5. Energy Efficiency
Certain types of asphalt shingles, such as cool roofing options, are designed to reflect more sunlight and absorb less heat. This can help lower cooling costs during the summer, contributing to improved energy efficiency.
Some brands offer ENERGY STAR®-certified asphalt shingles, which use special reflective granules to keep homes cooler and reduce the strain on air conditioning systems.
6. Fire Resistance
Asphalt shingles, particularly those rated Class A, offer excellent fire resistance. This adds a level of protection to your home, particularly in areas prone to wildfires or urban fire risks.
7. Readily Available
Since asphalt shingles are one of the most common roofing materials in Canada, they are easy to source. This means quicker installations and repairs compared to materials that require special orders.
The Cons of Asphalt Shingle Roofing in Vancouver
1. Vulnerable to Harsh Weather Over Time
While asphalt shingle roofing can handle Vancouver’s rainy climate, prolonged exposure to moisture can eventually cause shingles to deteriorate. Heavy winds, snowfall, and UV rays can also contribute to curling, cracking, or the loss of protective granules.
2. Shorter Lifespan Compared to Other Materials
Asphalt shingles typically last between 15 and 30 years, which is shorter than materials like metal, tile, or cedar shakes. If you’re looking for a roof with a lifespan of 50+ years, asphalt shingles may not be the best option.
The lifespan of an asphalt shingle roof depends on the type:
- 3-tab shingles: 15-20 years
- Architectural shingles: 20-30 years
- Luxury shingles: 25-40 years
3. Environmental Impact
Since asphalt shingles are petroleum-based, they have a higher carbon footprint than some alternative materials. While some manufacturers are developing recyclable shingles, the majority still end up in landfills. According to Natural Resources Canada, construction and demolition waste—including roofing materials—accounts for a significant portion of landfill waste in the country (source).
4. Susceptibility to Algae and Moss Growth
Vancouver’s damp climate creates the perfect conditions for algae, moss, and mildew growth on roofs. While some shingles are treated with algae-resistant coatings, older or lower-quality shingles may develop dark streaks and moss buildup, requiring more frequent maintenance.
5. Less Durable Than Alternatives
While asphalt shingle roofing is durable enough for most homes, it doesn’t match the strength of materials like metal or concrete. Heavy hail, falling branches, or extreme temperature shifts can cause asphalt shingles to crack or break.
How to Make Asphalt Shingles Last Longer in Vancouver
While asphalt shingles don’t last as long as some other materials, proper maintenance can help maximize their lifespan:
- Schedule Regular Roof Inspections: Checking for loose or damaged shingles helps catch small issues before they become costly repairs.
- Keep Gutters Clean: Clogged gutters can cause water backup, leading to roof damage over time.
- Prevent Moss and Algae Growth: Installing zinc or copper strips can help deter organic growth.
- Ensure Proper Attic Ventilation: Good ventilation helps prevent heat and moisture buildup, which can accelerate shingle aging.

The decision to install asphalt shingle roofing in Vancouver depends on your budget, long-term goals, and willingness to maintain the roof over time.
