These dams can tear apart your home so limit them by keeping your roof clear of snow. Ice dams and icicles form when the snow melts runs down your roof and refreezes near the edge. The ice traps meltwater which can seep back up under shingles and drip through the roof into your house causing wet and stained ceilings and walls and peeling paint and rot. Heat loss from a house snow cover and outside temperatures interact to form ice dams.

Nonuniform roof surface temperatures lead to ice dams. This only occurs when part of your roof. For ice dams to form there must be snow on the roof and at the same time higher portions of the roof s outside surface must be above 32 degrees f freezing while lower surfaces are below 32f. If dams are a serious threat to your roof the problem is usually due to poor ventilation.

An ice dam forms when the roof over the attic gets warm enough to melt the underside of the layer of snow on the roof. The calcium chloride will eventually melt through the snow and ice and create a channel for water to flow down into the gutters or off the roof. They re lightweight and easy to install in both new and existing homes. Work your way up stapling the side flaps to the trusses to create a 2 air channel between the roof decking and the panel.

Begin installing panels near the eaves. If you see icicles hanging from your roof you most likely have an ice dam. Successive panels overlap the ones below them. Ice house roof panels fit between 24 on center roof rafters.

If necessary use a long handled garden rake or hoe to push it into position.
