During British Columbia’s freeze-thaw cycles, ice damming occurs when snow on the roof melts and then refreezes at the colder eaves. This process creates a barrier of ice that forces water back up and under your shingles, leading to significant leaks.
The damage is often compounded by the repeating nature of these cycles:
- Widening Cracks: Water that seeps into small gaps in the roofing materials freezes at night and expands. This physical expansion widens existing cracks in the shingles.
- Compromised Seals: The constant expansion and contraction during these temperature swings compromise the shingle seals over time, allowing moisture to penetrate the roof structure.
- Eave Vulnerability: Because the eaves are typically colder than the rest of the roof, they are the primary site for ice buildup, which puts extra stress on the lower sections of your roofing system.
We recommend regular attic ventilation checks and proper underlayment to mitigate these risks. If you suspect your roof has been affected by recent temperature swings, you can claim your complimentary roof inspection to ensure your home remains protected. Please note that warranties vary by manufacturer and installation, and insurance coverage for roof damage depends on your specific homeowner’s policy and the cause of damage.
