Snow on your roof normally does not pose a problem. When your roof is subject to temperature differentials between the area over the attic and the bottom few feet near the eave, however, it may be vulnerable to ice dams and damaging water leaks.
As the snow melts across the upper reaches of the roof, it trickles down toward the eave. If the roof’s temperature at the eave is below freezing, that trickle freezes like a mini glacier until layer upon layer gradually builds up and a “dam” of ice forms.
When the ice dam is high enough, water collects behind it and forms a small pool. The water rises under shingles until it reaches a fastener hole and seeps into your home.
If your eaves are shielded with eave flashing, such as a self-adhering rubberized asphalt and fiberglass mat (that self-seals when penetrated by fasteners), you probably won’t have to worry about ice dams but if you don’t, it may be best to have a professional roofing contractor assess the damages.
