Household Horror #7: Ice Dams
Cold weather is about to attack your home and if you’re not careful, you may soon be facing one of the worst nightmares of winter: The Ice Dam. An ice dam forms when snow and ice melt on your roof, and then refreeze at the edge of the roof. This dam of ice prevents water from properly draining, and so it pools on the roof and sneaks back into your home where it can drip down through walls and floorboards.
The best way to prevent ice dams is with proper ventilation and insulation in your attic, which gives your roof a uniform temperature and culls the ‘freeze-thaw’ cycle. Having WinterGuard® waterproofing underlayment installed beneath your roof shingles will help ensure that water won’t creep back into the home.
