What We Check For Ice Dam Roof Repair
We review shingles, ridge caps, gutters, valleys, flashing, ice-dam paths at eaves, attic moisture, interior stains, and whether tarping is needed before permanent repair.
Ice dam damage concentrates at the eave line, just above the exterior wall. This is where the roof surface is coldest and where backup water pooling under the ice freezes and re-melts repeatedly. Shingle underlayment at the eaves — which should extend at least 24 inches inside the warm wall line in Maryland — is the primary protection against ice dam water infiltration. If the underlayment ice and water shield has failed or was not installed, we repair or add it as part of the fix.
