Spray Foam Protects Your New London, CT Home from Ice Dams and Moisture Damage

When winter settles in around New London, CT, homeowners often face one frustrating and costly issue—ice dams. These ridges of ice that form along the roof’s edge can lead to leaks, water stains, and even structural damage. Fortunately, there’s a reliable way to prevent these problems before they start: spray foam insulation from Custom Insulation Company, Inc.

What Causes Ice Dams?

Ice dams form when warm air from inside your home escapes through gaps and poorly insulated areas in the attic. This rising heat melts snow on the roof, which refreezes at the colder edges, creating ice buildup. Over time, trapped water can seep beneath shingles, damaging your roof, walls, and ceilings.

How Spray Foam Stops Ice Dams

Spray foam insulation provides a complete air seal, expanding to fill cracks and gaps that traditional insulation materials can’t reach. By preventing heat from escaping into the attic, your roof maintains an even temperature, helping snow melt uniformly—and eliminating the conditions that cause ice dams.

Added Protection from Moisture Damage

Spray foam does more than just stop ice dams. Its closed-cell structure helps block moisture and condensation, reducing the risk of mold, mildew, and rot. This makes it an excellent year-round defense against water damage, especially in coastal areas like New London where humidity can also be a concern.
