What are ice dams and what causes them?
Ice dams form when the snow on your roof melts and the water collects along the eaves. The eaves do not warm up as much as the rest of the roof, so the water can collect there and refreeze into a thick sheet of ice. Ice dams are harmful to your roof, shingles, and gutters. If there is water trapped behind the ice dam, it can travel underneath the shingles on your roof and flow into your home. This can cause extensive and expensive water-damage to your ceiling, walls, rugs, and possessions.
How to prevent ice dams from causing water damage to your home
Whenever enough snow accumulates on your roof, you are at risk for ice dams.
However, there are two main strategies for preventing dams and minimizing any damage they might cause.
Keep your roof cold
If your roof stays cold, the snow won’t melt all at once, increasing the likelihood of ice dam formation. You can keep your roof cold by blocking air leaks in your attic. To do this, you will have to pull back the insulation and block any leaks with caulking or foam. This keeps your roof evenly cool, preventing any warm patches from melting and refreezing in the eaves.
Install a protective ice and water barrier
For roof replacements, Northeast Home & Energy installs 6 feet of ice and water shield to better protect your home against ice dams. Depending on where you live and how old your home is, this protective membrane may need to extend at least 2 feet inside the heated wall space of a house.
