How to Prevent Ice Dams on Your Roof This Winter
Ice dams are one of the most common causes of winter roof leaks in Massachusetts. Learn what causes them, how to spot the warning signs, and what you can do to protect your home.
What Causes Ice Dams?
Ice dams form when heat escaping from your home warms the roof and melts snow, which then refreezes at the colder eaves and edges. Over time, this ridge of ice traps water behind it, forcing it up under your shingles and into your home.
In Massachusetts, ice dams are one of the leading causes of winter roof leaks and interior water damage.
Warning Signs to Watch For
Large icicles hanging from your gutters, water stains on ceilings or walls, and visible ridges of ice along your roof edge are all signs of ice dam activity. If you notice these, it's important to act quickly to prevent further damage.
How to Prevent Ice Dams
The best long-term defense is proper attic insulation and ventilation, which keeps your roof deck cold and prevents uneven melting. Keeping gutters clean in the fall also helps water drain properly.
Installing ice & water shield along the eaves during a roof replacement provides an extra waterproof barrier. If you're dealing with recurring ice dams, a free inspection from Jennifer Construction can identify the root cause.
