Do Icicles Form?
In freezing climates with homes that have inadequate insulation or ventilation, icicles may form. These icicles generally form with or without gutter protectors. In any event, they can easily be knocked off with a telescopic pole and brush assembly. Any Problems With Ice Dams? No gutter protector causes ice dams. Heat escaping through the roof because of inadequate insulation or ventilation melts snow on the roof which runs down the roof. When this water from the melted snow crosses over the eve line (where there is no heat loss), it freezes and the build-up of ice causes a dam effect. This dam of ice can be 6-to-8 inches in height and trap melted snow (water) on the roof. It is a misconception that ice creeps up the roof. In actuality, this trapped water simply seeps under the shingles and through inherent openings left from nailing the shingles. Ice dams are also more likely to occur in homes where attics house uninsulated vents from bathrooms, kitchens or heat pumps. Insulation shou
