When eavestroughs are clogged with leaves, twigs, and other debris, water is unable to flow freely through the system. This can cause water to spill over the edge, soaking into the roofing materials, and even into the walls and ceilings of your home. Over time, this can lead to mold growth, rotting wood, and structural damage. Additionally, water that flows down near the foundation can cause cracks, settling, and erosion, which may lead to costly repairs.
Ice Dams in Winter
Toronto winters are notorious for creating ice dams. These occur when heat from the attic melts snow on the roof, which then refreezes in the eavestroughs. A blocked eavestrough prevents proper drainage, and the water backs up, eventually freezing and forming large ice dams. These ice dams can cause significant damage to your roof, as well as increase the likelihood of water leaks into your home.
Pest Infestations
Clogged eavestroughs can become a haven for pests such as insects, rodents, and even birds. When debris accumulates, it creates the perfect environment for pests to nest. Insects like mosquitoes and ants may thrive in the stagnant water, while birds and squirrels can use the build-up to create nests. The presence of pests in your eavestroughs can result in further damage and require additional costs for removal and repairs.
Roof Damage
If water is unable to properly drain away from the roof, it can cause shingles to deteriorate faster than they should. The added weight of debris and water pooling on the roof can also strain roofing materials, leading to premature wear and tear. Neglecting eavestrough maintenance can lead to expensive roof repairs or even a premature roof replacement.
