Winter Waterproofing: Stop Leaks Before the Holiday Season

As temperatures drop and holiday preparations begin, one thing no property owner wants to face is unexpected leaks or water damage. Winter in the Lower Mainland and greater British Columbia brings heavy rain, snow, and ice—putting your roof and building envelope to the ultimate test. If your property isn’t properly waterproofed, minor issues can turn into costly repairs just as you’re getting ready to enjoy the season with family, tenants, or customers. At Citadel Roof & Building Maintenance, we specialize in helping residential, commercial, and strata clients protect their investments with professional waterproofing solutions tailored to our local weather conditions.


Why Winter Waterproofing Matters in BC


British Columbia’s winter weather is unpredictable and harsh on roofing systems. Even the smallest gap or crack can allow moisture to seep in, leading to structural damage, mold growth, and ruined interiors. Water intrusion is not only inconvenient—it can mean downtime for businesses, uncomfortable living for residents, and even safety hazards if left unchecked.


Many property owners discover leaks when it’s too late—after a season’s first big storm or freeze. That’s why winter waterproofing before the holidays is essential. By proactively sealing vulnerable areas, repairing roof membranes, and ensuring effective drainage, you can avoid emergency repairs and keep your property safe, dry, and comfortable through the winter months.


Common Causes of Winter Leaks


Understanding the typical sources of winter leaks can help you spot warning signs early. In our experience, the most common culprits include:


  • Worn or damaged roofing materials: Shingles, torch-on membranes, or flashing that have deteriorated over time create easy paths for water entry.
  • Clogged gutters and downspouts: Debris and ice buildup cause water to back up, leading to overflow and leaks at roof edges and eaves.
  • Improper sealing around vents, skylights, and chimneys: These areas are particularly vulnerable to water infiltration if caulking and flashing aren’t secure.
  • Flat roof ponding: Standing water on flat commercial or strata roofs accelerates membrane breakdown and raises the risk of interior leaks.
  • Inadequate attic ventilation: Poor airflow can cause condensation and ice dams, both of which contribute to winter leaks.


Don’t wait for these issues to escalate into emergencies. A thorough inspection by a local expert like Citadel can identify and address vulnerabilities before bad weather hits.
