flashing ice dam

Roofing

The answer to 'flashing ice dam' is that ice dams can cause damage to roof flashing, which are the metal strips used to seal joints and prevent leaks. Ice dams form when snow on the roof melts, then refreezes at the roof's edge, creating a barrier that traps water. This can force water under the shingles and into the home, potentially damaging the flashing.

Some common causes of flashing ice dams include poor attic insulation, inadequate ventilation, and excessive snow buildup. Symptoms include water stains, peeling paint, and mold growth inside the home. Solutions may involve improving insulation, adding roof vents, and regularly clearing snow from the roof. In severe cases, professional roof repairs or replacement may be required to fix damaged flashing.
