3 Ways To Stop Ice Dam Formation

Attic insulation can reduce the transference of heat to the roof.

Three Ice Dam Prevention Measures

An ice dam forms when the snow melts on a roof and runs down to the edge and refreezes. Maintaining consistently cool attic and roof temperatures and functional drainage are the best ways to prevent a dam from forming. Here are three of the most effective ice dam prevention measures for residences in Palmer Lake, CO.

1. Limit Heat Loss

Many homes lose one-third of interior heating to the attic through ceilings. Closing bypasses around ceiling penetrations and other cracks and gaps will increase heating efficiency and prevent elevated attic temperatures that lead to ice dams.

2. Insulate and Ventilate an Attic

Attic insulation can reduce the transference of heat to the roof. Most building codes specify 12 to 14 inches of cellulose or fiberglass insulation. An attic specialist can also eliminate gaps that allow heat to travel up, melt snow, and cause an ice dam. Venting is another effective way to maintain cooler attic temperatures. The best locations for roof vents are in overhangs and along or near the peak.

3. Use Prevention Products

A specialized roof rake can be helpful for removing snow. In addition to posing a risk of melting and refreezing, snow also adds excess weight to a roof during a winter storm. Areas, where dams tend to form, can be equipped with high-resistance heat cables that run through a downspout. If a dam has already formed, calcium chloride can melt ice without damaging roofing materials. Use this product according to the instructions and cover plants situated beneath drainage.

Resolving the underlying cause is the best way to stop ice dam formation. Maintaining consistently cool temperatures throughout an attic and across a roof eliminates the factors that cause snow to melt and refreeze. Roof rakes and products that promote melting are fallbacks that may reduce the risk of roof damage and water damage at a residence in Palmer Lake, CO.
