Fast Fixes for Ice Dams

Fixes for Ice damsHeated gutter cables, cleaned gutter down spouts, additional attic insulation are preventive solutions to ice dams on your Lakeville home.  However, these solutions you can employ next fall.  What can you do about potential ice dams you have right now? 

I found an article by Joe Hurst-Wajszczuk from this Old House magazine that may give you some help right now.  Enjoy.

 

Icicles hanging along the eaves of your house may look beautiful, but they spell trouble. That’s because the same conditions that allow icicles to form—snow-covered roofs and freezing weather—also lead to ice dams: thick ridges of solid ice that build up along the eaves. Dams can tear off gutters, loosen shingles, and cause water to back up and pour into your house. When that happens, the results aren’t pretty: peeling paint, warped floors, stained and sagging ceilings. Not to mention soggy insulation in the attic, which loses R-value and becomes a magnet for mold and mildew.

Birth of an Ice Dam
1. Heat collects in the attic and warms the roof, except at the eaves.
2. Snow melts on the warm roof and then freezes on the cold eaves.
3. Ice accumulates along the eaves, forming a dam. Meltwater from the warm roof backs up behind it, flows under the shingles, and into the house.

Fast Fixes
Hacking away at ice dams with a hammer, chisel, or shovel is bad for your roofing—and dangerous for you. And throwing salt on them will do more to harm to your plantings than to the ice. Short of praying for warm weather, here are two stop-gap measures we recommend:

Blow in cold air: Take a box fan into the attic and aim it at the underside of the roof where water is actively leaking in. This targeted dose of cold air will freeze the water in its tracks. “You’ll stop the leak in a matter of minutes, “says This Old House general contractor Tom Silva.

Rake it: Pull off snow with a long-handled aluminum roof rake (purchase at your home improvement store) while you stand safely on the ground. A rake with wheels won’t harm the roofing.
