Ice Dams in Connecticut: Why They Happen & When to Call All Site Builders

Connecticut winters create the perfect conditions for ice dams — thick ridges of ice that trap water and force it under shingles. Left unchecked, they cause leaks, mold, and costly interior damage. At All Site Builders, we help homeowners across CT detect, remove, and prevent ice dams with professional inspections and safe removal. Don’t wait for a flood — act before it’s too late.

Connecticut winters can be brutal on homes—especially your roof. After the most recent storm, many homeowners saw heavy snow followed by warmer temps and then a hard freeze. That back-and-forth weather is exactly how ice dams form, and they’re one of the most common (and damaging) winter roofing problems we see across Connecticut.

Ice dams are often the first sign that something isn’t right with your roof during the winter months. Knowing what causes them—and when to take action—can save you from leaks, interior damage, and expensive repairs down the road.

What Are Ice Dams?

An ice dam is a thick ridge of ice that forms along the edge of your roof, usually near your gutters. They might not look like a big deal at first, but they can stop melting snow from draining properly. When that water has nowhere to go, it can back up under your shingles and find its way into your home.

Over time, this can cause:

Roof leaks and water damage
Damaged shingles and roofing materials
Wet insulation and potential mold growth
Stains on ceilings and walls
Damage to gutters, fascia, and siding

How Do Ice Dams Form?

Ice dams usually come from a mix of snow buildup, heat loss, and temperature swings. Here’s the typical cycle:

Snow piles up on the roof
Heat escapes from inside the home and warms parts of the roof
Snow melts in those warmer areas
The water runs to colder edges and refreezes
Ice continues to build, blocking proper drainage

This is especially common in Connecticut, where winter weather can change rapidly.

“6 inches of water behind an ice dam in Wallingford — and the homeowner didn’t know. Don’t wait for leaks. Call for a free inspection.”

— Bruce, Owner at All Site Builders

Signs Ice Dams May Already Be Causing Damage

You don’t always need to see the roof to know there’s a problem. Watch for:

Large icicles hanging from gutters or roof edges
Water stains on ceilings or walls
Peeling paint or bubbling drywall
Dripping water during cold weather
Sagging or damaged gutters

If you notice any of these, it’s best to act sooner rather than later.

Why Ice Dams Aren’t Something to Ignore

Ice dams don’t just “fix themselves.” As long as freezing and thawing continues, the damage can get worse. DIY fixes often don’t solve the root problem—and in some cases, they can actually cause more harm to your roof if left unattended.

A professional inspection and proper removal are the safest ways to protect your home.
