How Winter Weather Damages Dirty Roofs and Ways to Prevent It?
Roof damage from winter weather is well known, and the hazards increase if a roof is unclean or neglected. Debris, dirt, and organic materials like moss or leaves clog drainage systems and retain moisture, leaving your roof more susceptible to the special risks of winter. How are Dirty Roofs Affected by Winter Weather? Intrusion of Water and Ice Dams: Ice dams can form when snow builds up and melts unevenly at the colder roof edges as a result of inadequate insulation or debris accumulation. Because these ice dams prevent adequate drainage, water collects and seeps beneath shingles, resulting in leaks, damaged insulation, and water stains inside. Cracks Are Worsened by the Freeze-Thaw Cycle: Moisture is frequently present in tiny crevices or beneath debris on dirty roofs. This moisture expands and freezes in response to temperature changes, causing shingles to curl, fracture, or even break off. This cycle has the potential to weaken your roof’s structural integrity over...
