Look out for ice dams on your roof

TERRE HAUTE, Ind. (WTHI) – If you see icicles hanging from your roof it might look pretty, but experts say this could be a sign of concern. With the recent snow and freezing temperatures, ice dams could develop.

An ice dam forms at the edge of a roof, preventing melting snow from flowing off the roof. In this case, the roof, gutter, and even mold or mildew in your walls can be damaged.
Jimmy Harness, sales manager at Guarantee Roofing in Terre Haute, said improper insulation is a big reason ice dams are being built.

“If your attic isn’t properly ventilated, it heats your roof and the snow melts and gets to the cold eaves where it’s not heated. Then when that cold air hits the melted water again, it really freezes on the edge of the roof, and then it begins to secure itself and continue to do so throughout the process of temperature fluctuating throughout the week, “explained Harness.

Ice dams can also form when temperatures are slightly above freezing and the sun comes out. The snow on your roof will begin to melt, but will freeze as soon as it hits your eaves. If a dam builds up, it will get under your shingles and damage your house deck and drywall.
Although you may be tempted to climb a ladder and take it off yourself, experts say it can cause a lot more damage.

If you notice an ice dam on your roof, get professional help. Climbing a ladder or roof when it is wet and ice can be dangerous.
