Protect Your Roof & Home
Ice dams form when heat escapes through inadequate attic insulation, causing snow to melt and refreeze at the roof edge. Proper insulation prevents this destructive cycle.
Ice dams are a common problem in Long Island's cold winters. They occur when warm air from your home escapes through the attic, melting snow on the roof. The melt water then refreezes at the colder roof edge, creating a dam that can cause water to back up under shingles and leak into your home.
The most effective solution is proper attic insulation combined with adequate ventilation, which keeps your roof cold and prevents snow melt.
Proper R-value prevents heat from escaping through the attic floor.
Seal gaps and cracks that allow warm air to enter the attic space.
Allow cold air to flow through the attic, keeping the roof cold.
Draw cool air into the attic through soffit vents.
Exhaust warm, moist air through ridge or gable vents.
Protect vulnerable roof edges with membrane underlayment.
Long Island homes need substantial attic insulation to prevent ice dams.
Proper ventilation ratio ensures cold roof surfaces and prevents ice dams.
Ice dams can cause thousands of dollars in roof damage and interior water damage. Prevention is much more cost-effective than repair.
