While you can't change the weather, you can minimize some of winter's biggest threats to your home. Heavy snow accumulation can pose a threat to your home-- both as it builds up and as it melts.
The three most important things to do are:
1.
Remove snow from
basement stairwells, window wells and all walls. Melting snow can lead to water
damage and moisture intrusion.
2.
Keep your attic well
ventilated to maintain a temperature close to that of the outdoors to minimize
the risk of ice dams forming. A warm attic melts snow on the roof, causing
water to run down and refreeze at the roof's edge, where it's much cooler. If
ice builds up and blocks water from draining, water is forced under the roof covering
and into your attic or down the inside walls of your house.
3.
Watch for snow
accumulation on the leeward (downwind) side of a higher-level roof, where
blowing snow will collect. For safe removal that won't endanger you or damage
your roof, consult a roofing contractor for a referral.
