Beat Ice Dams & Winter Condensation

The Attic System SE Wisconsin Homes Need

Few winter problems are more frustrating than roof ice dams—followed by stains, drips, and damaged insulation. In Southeast Wisconsin’s freeze‑thaw cycles, the fix is a system, not a single product: air sealing, continuous insulation, and balanced ventilation working together.

Here’s how we approach ice dam prevention for local homes.

Step 1: Air Seal the Attic Floor

Stop warm, moist air from escaping into the attic. We seal around light fixtures, bath fan housings, plumbing/electrical penetrations, and the attic hatch. This reduces melt lines that start damming.

Step 2: Insulate to the Right R‑Value

We add or top up insulation to create a continuous thermal blanket. Proper coverage (no gaps, no compressed batts) matters more than raw inches.

Step 3: Balance Ventilation (Intake + Exhaust)

Cold, dry air must enter at soffits and exit at the ridge to flush moisture and maintain a cold roof deck. We clear baffles, verify airflow, and correct blocked vents.

Step 4: Vent Bath & Kitchen Fans to the Exterior

Moist air vented into an attic accelerates condensation and mold. We route fans outside with insulated ducting and appropriate caps.

Step 5: Upgrade Problem Windows & Doors Below

Leaky openings create cold interior surfaces and condensation that looks like roof issues. Replacing targeted units improves comfort and humidity control.

Step 6: Plan for Safe Roof/Attic Access

If inspection reveals structural or ventilation constraints, we’ll create safe access and a scope that solves the underlying issues—not just the symptoms.

Why This System Works in SE Wisconsin

Our lake‑effect climate drives repeated thaw/refreeze cycles. A tight attic floor, correct R‑value, and balanced ventilation keep the roof deck uniformly cold, so snow doesn’t melt at the peak and refreeze at the eaves.
