Ice dams and water backup at the eaves
Why it happens here
Midway winters bring snow and freezing temperatures. When attic heat escapes, it melts snow on the upper roof. That water refreezes at the cold eaves, forming a dam that forces water under the shingles.
Our approach
We install ice and water shield at the eaves and valleys on every replacement. If you already have ice dam damage, we repair the shingles and flashing and check attic ventilation to stop it from happening again.
