Under certain conditions, ice and snow may accumulate on your roof. If you notice ice and/or snow forming on your roof, you should monitor it closely and, possibly, consult a professional for help. Ice and snow can cause problems if left unattended.
One condition to watch for is called “ice damming.” Ice damming happens when indoor heat warms parts of the roof surface and melts accumulated snow. As snow melt runs down the roof, it re-freezes near the cool edge of the roof creating an “ice dam.” The cycle of melting and re-freezing snow repeats itself, and the ice dam grows.
Ice dams can cause significant damage if water works its way under shingles and into your home. Your roof is constructed to meet or exceed industry codes. Your New Home Warranty does not provide any coverage against ice dams or for any damage associated with ice dams.
If you live in an area that is prone to ice damming, you should have a preventative plan in place to help avoid problems associated with ice damming. More information is here: Preventive Maintenance Plan for Ice Damming.
