Roof Leak After Snow

An ice dam occurs when snow melts and the water freezes when it hits the colder edges of your roof.

Roof leak after snow.

The soffit that meets the roof is one of the toughest areas to waterproof. Heat leaking up from your home is melting the snowpack in the tight roof canyon. Likewise a heavy blanket of snow can hide the significance of an ice dam making it hard to ascertain it s size. If you have a low slope roof area accumulations as little as 1 thick can cause problems.

The steeper your roof pitch the more ice it takes to create interior leaking see ice dam case study 09. In order to avoid melting snow and roof leaks you need to have very good insulation ventilation and an effective air barrier. Most roofing materials are designed to work under the influence of gravity. A roof leak at the edge of a dormer can allow a lot of water to enter your home.

It was warm enough for the snow to melt during the day but it would drop below freezeing at night. The roof leaked a few days after a foot of snow had fallen. This keeps the warm air in and the roof at a constant temperature thus eliminating melting snow and roof leaks from occurring. Dormer leaks can be caused from a number of issues.

This roof leaks during the snowy part of winter and during storms in the summer certainly due to poor flashing. The cold weather turns the super chilled water to ice and the ice pack begins to get thicker and thicker creating a dam quite like hoover dam but a much smaller. Worn out flashing or missing sealant can also cause roof leaks around dormers. Protection for the perishable areas of your roof.
