Regularly cleaning and inspecting your gutters can help prevent clogs and reduce the risk of water infiltration.
Ice Dams
In cold climates, ice dams can be a common cause of water infiltration. Ice dams form when snow on the roof melts and then refreezes near the eaves of the roof, creating a barrier that prevents proper drainage. As the melted snow backs up behind the ice dam, it can seep under the shingles and into your home. Proper insulation, ventilation, and regular removal of snow from the roof can help prevent the formation of ice dams and reduce the risk of water infiltration.
Cracked Chimney or Skylight
A cracked chimney or skylight can also be a source of water infiltration. Over time, the mortar and sealant around chimneys and skylights can deteriorate, leading to cracks or gaps. These openings allow water to enter and cause water infiltration. Regularly inspecting and repairing any cracks or damage to chimneys and skylights is essential to prevent water infiltration.
Condensation
While not directly related to the roof, condensation can contribute to water infiltration in your home. Condensation occurs when warm, humid air comes into contact with a cool surface, such as the underside of the roof or ceilings. This can create moisture, which can lead to mold growth and water damage over time. Proper ventilation and insulation in your home can help prevent condensation-related water infiltration.
