Continuing our series of how to prepare your Vancouver roof for the winter, let’s talk about asphalt roofs. Asphalt is a common shingle roofing system popular for its durability and cost-effectiveness, but proper maintenance is crucial to extend its lifespan and prevent damage. Here are some tips to help you get your asphalt roof ready for winter.
Part 2: How to Prepare Your Asphalt Roof for Winter in Vancouver, BC
Here are a few essential tips to prepare your asphalt roof for winter this year:
Conduct a Thorough Inspection
Start with a thorough inspection of your roof. Look for:
Cracked or Missing Shingles – Asphalt shingles are designed to withstand various weather conditions, but age and wear can lead to damage. Missing or cracked shingles can expose your roof to leaks, so address these issues promptly.
Flashing Issues – Ensure that the roof valleys and flashing around vents, chimneys, and skylights are intact. Properly installed flashing is critical for keeping water out of vulnerable areas. Check the flashing for signs of rust, wear, or separation. The valleys are especially important, as they channel water off the roof, so make sure they are clear of debris and that the flashing is secure.
Signs of Mold or Mildew – Check for any signs of mold or mildew on your roof. If you find any, address it promptly to prevent it from spreading. Regular maintenance can help keep your asphalt roof in top shape, reducing the risk of costly repairs.
Keep Your Roof Clean and Watertight
Clean Your Gutters and Downspouts – Clogged gutters can lead to water backing up and pooling on your roof, increasing the risk of leaks and ice dam formation. Clean out leaves and debris, and make sure downspouts are directing water away from your home’s foundation. If you notice any sections of your gutters that are sagging or disconnected, repair or replace them to ensure proper water flow.
Debris Accumulation – Remove leaves, branches, and other debris. Accumulated debris can trap moisture, increasing the risk of mold and moss growth, which can deteriorate asphalt shingles over time.
Trim Overhanging Branches – Branches that hang over your roof can pose a risk during winter storms. Trim any branches that could fall or scrape against your roof, preventing potential damage and reducing debris accumulation.
Seal Vulnerable Areas – Using roofing cement or a high-quality sealant, reseal any areas where the flashing is no longer properly sealed or to caulk around chimneys, vents, and other areas where water might penetrate. This is especially important for asphalt roofs, as they need to be watertight to perform effectively under heavy rain and snow.
Plan Ahead
Plan for Snow Removal – Heavy snow can be particularly problematic for asphalt roofs. If you anticipate significant snowfall, invest in a roof rake to safely remove snow buildup. Be cautious not to damage the shingles while doing so, and always work from the ground when possible.
Prevent Ice Dams with Heat Cables – Ice dams are a common problem for asphalt roofs in colder regions. In Vancouver, where snow can accumulate and then melt during the day, ice dams can form when the water refreezes at the edge of the roof. To prevent this, you can install heat cables along the roof edge to keep the temperature consistent and help melted water flow off the roof. Be sure to hire a professional to install them to ensure they are safely and effectively positioned.
Schedule Professional Maintenance – If you’re unsure about the condition of your roof or feel uncomfortable performing these checks yourself, consider hiring a professional roofing contractor.

Preparing your asphalt roof for winter in Vancouver is essential for protecting your home from the elements.
