Ice Damm Roof

This only occurs when part of your roof warms to above 32 degrees f warm enough to melt the snow while the roof edge remains below freezing.

Ice damm roof. Now that you know how ice dams form here s a quick and easy way to prevent them. This scenario is often the result of a warm attic. Ice dams and icicles form when the snow melts runs down your roof and refreezes near the edge. They can also cause considerable roof leaks that lead to interior damage.

How to prevent ice dams use heated cables. An ice dam is a solid ridge of ice that forms along the edges of your roof. Snow starts to melt in certain areas of the roof which are warmer than others due to heat loss from the attic. An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow water from draining off the roof.

An ice dam is an ice build up on the eaves of sloped roofs of heated buildings that results from melting snow under a snow pack reaching the eave and freezing there. To take a more pro active approach in preventing ice dams you can install ice belt metal panels which are installed along the eaves to block water. Ice belt metal panels many roofs are made of shingles which work well to remove water until it starts to travel upward. The meltwater then runs down toward the colder eave overhang where it freezes.

Ice dams are those beautiful but deadly mounds of ice and icicles that you see along the edge of some roofs. Once this thick ice forms it prevents melting snow from running off the roof. We say they are deadly because sheets of ice start to break loose as the weather gets a little warmer stabbing or crushing anything in its path. Meltwater from the warm roof backs up behind it flows under the shingles and into the house.

Attached with clips along the roof s edge in a zigzag pattern heated cables help prevent ice dams that lift shingles and cause leaks. The water that backs up behind the dam can leak into a home and cause damage to walls ceilings insulation and other areas. Ice dams form when the snow melts on an upper warmer part of a roof.
