skylight ice dams

Roofing

The answer to 'skylight ice dams' is that skylight ice dams occur when ice builds up around the perimeter of a skylight, preventing proper drainage and leading to leaks and water damage. This is a common problem in colder climates where heavy snowfall and freezing temperatures are common.

Skylight ice dams are typically caused by poor insulation and ventilation around the skylight, which allows warm air to escape and melt snow on the roof. As the melted snow refreezes around the skylight, it forms a dam that traps additional water, leading to leaks and potential damage to the skylight and surrounding roof area.

Step-by-Step Guide

  1. 1

    Inspect the Skylight

    Carefully examine the skylight and surrounding roof area for signs of ice buildup, water stains, or other damage.

  2. 2

    Clear Snow and Ice

    If the ice dam is small and accessible, you may be able to carefully remove the ice using a roof rake or other tool, taking care not to damage the skylight.

  3. 3

    Apply Heat

    Consider using a de-icing cable or tape to melt the ice dam, or apply a chemical ice melter to help break up the ice.

  4. 4

    Improve Insulation and Ventilation

    To prevent future skylight ice dams, ensure the area around the skylight is properly insulated and ventilated to minimize heat loss and ice buildup.
