The answer to 'skylight ice dams' is that ice dams around skylights are a common problem that can occur during the winter months. Ice dams form when heat from the home melts snow on the roof, causing the water to refreeze at the roof's edge or around the skylight. This can lead to leaks, water damage, and even the collapse of the skylight.
The main causes of skylight ice dams include poor insulation, inadequate ventilation, and heat loss through the skylight. Symptoms include icicles forming around the skylight, water stains on the ceiling, and water pooling around the skylight. Solutions can include improving insulation, adding ventilation, and using heat cables or de-icing systems to prevent ice buildup. Homeowners may be able to address minor ice dams themselves, but larger issues or structural damage often require the expertise of a professional roofing contractor.
