ICE DAMS DESTROY
FROM THE
INSIDE OUT.

Trapped water behind ice ridges soaks through your decking, into your insulation, and down your walls. By the time you see the stain on your ceiling, thousands of dollars in damage has already happened.

The Problem

The Okanagan Freeze-Thaw Cycle Is Brutal.

Warm air from your living space rises into the attic and heats the roof deck. Snow on the warm section melts, runs down to the cold eave overhang, and refreezes — forming a dam. Water pools behind the dam and has nowhere to go but under your shingles.

Once water is under the roofing, it soaks into the decking, drips onto insulation, and runs along framing members into your walls and ceilings. Mold grows. Wood rots. And the cycle repeats with every freeze-thaw — which in the Okanagan means dozens of times per winter.

Anatomy

Anatomy of an Ice Dam

Scroll to watch how a warm attic turns winter snow into thousands of dollars in damage — and exactly how we stop it.

Before — ice dams form
  • A warm attic heats the roof deck
  • Snow melts and runs to the cold eave
  • Meltwater refreezes into an ice dam
  • Trapped water backs up under the shingles — and leaks inside
After — prevented
  • Insulation keeps heat in the living space
  • Soffit-to-ridge airflow keeps the deck cold
  • Ice & water shield seals the eaves
  • Snow stays frozen — no dam, no leak
Our Approach

The Ice Dam Defense System

01

Root Cause Analysis

We don't just treat symptoms. We identify exactly why ice dams form on your specific roof — ventilation deficiencies, insulation gaps, complex geometry, or a combination.

02

Ventilation Correction

Balanced intake and exhaust ventilation eliminates the warm spots on your roof deck that cause uneven melting. We calculate the exact NFA your attic needs.

03

Ice & Water Shield

Self-adhering waterproof membrane installed on all vulnerable areas — eaves, valleys, around penetrations, and along wall-to-roof transitions. Your last line of defense.

04

Heat Trace Integration

Strategic heat cable placement along eaves, valleys, and in gutters keeps critical drainage paths clear through the worst of winter.

05

Drip Edge & Flashing

Properly detailed metal drip edge and step flashing direct meltwater off the roof instead of letting it creep underneath. Precision metalwork, not generic builder-grade strips.

06

Post-Install Monitoring

We check in during your first winter after installation to verify the system is performing. If adjustments are needed, we make them — included in your project scope.

Understanding the Problem

Anatomy of an Ice Dam

SNOW LAYER WARM AIR RISING POOLED DAMAGE ICE DAM
1
Warm Attic Space
Heat from your living space rises into the attic and warms the roof deck from below.
2
Snow Melts on Warm Section
The heated roof deck causes snow to melt even in freezing temperatures. Meltwater runs downhill.
3
Ice Dam Forms at Cold Eave
Meltwater reaches the cold overhang (no heat below) and refreezes, building a ridge of ice.
4
Water Pools Behind Dam
With nowhere to drain, water backs up behind the ice ridge and is forced under shingles.
5
Interior Water Damage
Water penetrates the decking, soaks insulation, and runs into walls and ceilings causing rot and mold.
Common Questions

Got Questions?

Look for water stains on ceilings near exterior walls, peeling paint, damp spots in the attic, or icicles hanging from your eaves. If you see ice ridges forming at the edge of your roof during winter, damage may already be occurring. Our free inspection can confirm it — and when moisture is suspected, a thermal scan reveals exactly where it's trapped in your roof system.
Yes. The key is addressing the root cause — not just the ice. Our system corrects ventilation deficiencies, adds waterproof membrane protection, and optionally integrates heat trace for severe cases. Once the heat-loss pattern on your roof is corrected, ice dams stop forming.
Insulation alone rarely solves ice dams. While it helps reduce heat transfer, without proper ventilation the heat still accumulates in your attic. You need balanced airflow to carry that heat out. We assess both insulation and ventilation together for a complete solution.
The best time is before winter — ideally late summer or early fall. However, we can install ice and water shield membrane and heat trace systems year-round. If you're currently experiencing ice dam damage, call us immediately for emergency assessment and mitigation.
