Taking Action Against Ice Damming This Winter

What You Should Know to Help Protect Your Roof

Are ice dams damaging your roof? Above average snowfall and below average cold temperatures throughout the winter season may leave homeowners finding that the wrath of this winter has left long-term roof damage in its wake.

In regions hit hard during winter, the seemingly harmless icicles dangling from rooftops may actually signal potential ice dams. An ice dam is a wall of ice along the edge of the roof that forms when melting snow continually thaws over warmer portions of the roof and refreezes along the roof’s colder eaves. The melted water that pools behind the ice dam gets trapped, creating the potential to leak into the home and cause damage to walls, ceilings, insulation and other structural areas. To help avoid the increased potential for ice dam damage on your home, consider following these tips:

Proactive: Bring in the Trusted Experts. Call a local expert who can evaluate your roof for damage and determine what your roof needs are. This could include additional shingles, underlayments, ice and water barrier products, ventilation and/or additional insulation.
