Ice & water shield is a thick, sticky-back underlayment that will adhere to your roof deck and prevent water from seeping into your home if it gets under your shingles. If an ice dam occurs on your roof and water backs up under the shingles it will seep down into your home through the nail holes holding the shingles on and into your attic. Once there it will saturate plywood, insulation, and drywall, which will lead to interior home repairs on your walls, ceilings, paint, and insulation. Ice & water shield acts as a gasket around each of those nail holes, creating a water-tight barrier that won’t let any leaks happen. If water does get under the shingles, it will stay on top of the ice & water shield and run off your roof where it belongs.

This will help prevent some things such as mildew growth, buckling of shingles, Ice build up.
