Ice dams are those beautiful but deadly mounds of ice and icicles that you see along the edge of some roofs.
Snow starts to melt in certain areas of the roof which are warmer than others due to heat loss from the attic.
Roof deicing cables for ice dam prevention.

They can also cause considerable roof leaks that lead to interior damage.
The cables will create lots of zig zagging channels of melted snow across your roof.
Heat coils for ice dam prevention are of course the same thing as heat cables.

Deicing cables heat the roof edge and keep it free of ice.
Ice dams can pose many problems.
Install the cables along the roof edge where ice tends to build up.
Heat cables for ice dams.
Secure shingle clips to roof shingles using a flathead screwdriver making sure to align them in a zigzag pattern.

An ice dam is a solid ridge of ice that forms along the edges of your roof.
Clip in the cable along the same zigzag pattern as the shingle clips.
Ice dams result from repeated cycles of thawing and freezing which cause snow and ice to melt then freeze along the roof edge lead photo.

This solution allows you to equalize your roof s temperature by heating it from the outside instead of blowing in cold air from the inside as we mention next in fast fixes.
Heated roof systems offers you our exclusive patented technology that provides a concealed snow melt mat placed under various roofing material to eliminate ice dams.
Attached with clips along the roof s edge in a zigzag pattern heated cables help prevent ice dams that lift shingles and cause leaks.
Where does that melted snow go.
