Ice Shields

In the Inspector's Notebook, inspector Tim Hockenberry takes a closer look at one of the problems found in the home inspection. Ice shields installed underneath roof shingles help to keep water from melting ice outside the home instead of leaking through the roof . If you live in an area where the average winter temperature is below freezing, you might need an ice shield on your roof.

Ice shields are self-adhering plastic membranes that are applied to the roof prior to the application of a roof covering such as shingles, tile or metal. The ice shield membrane is sandwiched between the covering and the deck of the roof and nailed in place. Typically ice shields are installed in areas that leak: above the eaves, around the chimney and skylights.

You may need an ice shield on your roof if you notice water stains on the inside walls of the attic or if you live in an area that typically experiences harsh, wet winters. If you think you need an ice shield, consult a roofing contractor who will help you evaluate your situation. Together with proper insulation and ventilation, an ice shield on your roof can help keep your home dry and comfortable.
