Can Roofers Work in Winter?
Yes — with temperature considerations. Emergency repairs happen year-round. Shingle installation has a minimum temperature of 4°C, but experienced Guelph roofers use cold-weather techniques when needed.
Understanding Ice Dams
Ice dams form when heat from your living space melts snow from the bottom up. Meltwater runs to cold eaves, refreezes, and backs water under shingles into your home.
Prevention
Long-term: proper attic insulation and ventilation. Short-term: clear eavestroughs before winter. Ice and water shield at eaves is mandatory under Ontario Building Code.
Snow Loads
If snow exceeds 18–24 inches, use a roof rake from the ground to remove some load — especially on older Guelph homes.
