Ice On Roof Of House

Begin installing panels near the eaves.

Ice on roof of house.

If you see icicles hanging from your roof you most likely have an ice dam. The water trickles down between the layer of snow and the shingles until it reaches the eave of the roof which stays cold because it extends beyond the side of the house. 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. 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.

These dams can tear apart your home so limit them by keeping your roof clear of snow. Stop ice dams with a cold roof. Heat loss from a house snow cover and outside temperatures interact to form ice dams. Successive panels overlap the ones below them.

Nonuniform roof surface temperatures lead to ice dams. Ice house roof panels fit between 24 on center roof rafters. Work your way up stapling the side flaps to the trusses to create a 2 air channel between the roof decking and the panel. They re lightweight and easy to install in both new and existing homes.

Lay the hose onto the roof so it crosses the ice dam and overhangs the gutter. If necessary use a long handled garden rake or hoe to push it into position. 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. This only occurs when part of your roof.

Ice dams happen when ice melts trickles down the roof then freezes again.
