The answer to 'flashing ice dam' is that ice dams can cause damage to roof flashing, leading to leaks and water intrusion. Ice dams form when heat escapes from the home and melts snow on the roof, which then refreezes at the roof's edge. This can push up under the shingles and damage the flashing, allowing water to seep in. Solutions include improving attic insulation, sealing air leaks, and installing heat cables to melt the ice. However, severe damage to flashing may require professional roof repair or replacement.
Homeowners should inspect their roof regularly for signs of flashing damage from ice dams, such as cracked or missing caulk, lifted shingles, and water stains inside the home. While minor flashing repairs can sometimes be done DIY, it's generally best to call a professional roofer to assess and fix the problem, especially if the flashing is severely compromised.
