Ice dams cause serious roof damage in Edmonton winters. Learn what they are, how they form, prevention strategies, and professional repair solutions.
Ice dams are the bane of Edmonton winter roofing. These ridges of ice form along roof edges and block proper water drainage, forcing water back under shingles and into your home. Ice dam damage costs Edmonton homeowners thousands annually in repairs and water damage restoration. Understanding how ice dams form, how to prevent them, and when professional repair is needed protects your home during harsh winters.
What Are Ice Dams and How Do They Form?
Ice dams form through a specific sequence of events common in Edmonton winters. First, heat escapes through your roof into the attic space, warming the roof surface above the main living area. Snow on this warmed portion melts, creating water that flows downward toward the roof edge.
At the roof edge, the structure lacks underlying insulation and attic heat. The roof temperature drops below freezing, and the water refreezes. This cycle repeats throughout winter as snow accumulates and melts. The result is an ice ridge—an ice dam—along the roof edge.
Behind this ice barrier, water can't drain properly. It backs up under shingles and gets forced into your home through small gaps in shingles, flashing, or soffits. This water enters your walls, insulation, and attic, causing moisture damage, mold growth, and structural deterioration.
The Real Cost of Ice Dam Damage
Ice dam repair alone costs $4,180+ per incident. But that's just the visible structural damage. Behind walls, water is saturating insulation, rotting framing, and creating ideal conditions for mold. Mold remediation, water damage restoration, and structural repair can total $10,000-$50,000 or more depending on damage extent.
Insurance sometimes covers ice dam damage if it resulted from inadequate ventilation or insulation issues rather than poor maintenance. Documentation of preventive efforts helps support claims.
Prevention: The Best Approach
Proper insulation and ventilation prevent most ice dams. Your attic should remain cold, close to outdoor temperatures, preventing heat from escaping through the roof. Check that insulation fills to the recommended depth—typically R-38 to R-60 depending on Edmonton's climate zone.
Ventilation should move cold outside air across the attic ceiling, removing any heat that does escape. Soffit vents provide intake; ridge vents provide exhaust. This continuous air circulation keeps attic temperatures low, preventing roof surface warming.
Ductwork from bathroom and dryer vents should exhaust outside, not into your attic. These moisture sources create condensation that worsens ice dam conditions. Proper ductwork routing prevents this problem.
Air sealing gaps in your attic prevents warm air from rising into the attic space. Check around penetrations, light fixtures, and framing for gaps where warm air escapes. Sealing these gaps reduces heat loss and ice dam risk.
When to Call Professional Roofers
If ice dams have already formed, removing them requires professional equipment and expertise. DO NOT attempt to remove ice dams yourself. Chipping at ice risks personal injury and additional roof damage. Our team uses safe, professional techniques to remove ice buildup and address underlying causes.
If water has already entered your home, professional water damage assessment becomes urgent. Water sitting inside your walls activates mold growth within 24-48 hours. Quick response limits damage extent.
Professional roofers also assess whether your roof's insulation and ventilation are adequate for Edmonton's climate. If insufficient insulation or ventilation caused the ice dam, we recommend upgrades that prevent future occurrences.
Professional Ice Dam Repair Process
Our team addresses ice dam problems systematically. First, we safely remove accumulated ice if necessary. Second, we identify water entry points and dry affected areas. Third, we assess attic insulation and ventilation adequacy. Fourth, we recommend prevention measures for future winters.
If structural damage or mold has developed, we coordinate with water damage specialists. If insulation upgrades are needed, we provide recommendations and estimates. We provide transparent pricing for all recommended work.
Long-Term Ice Dam Prevention
Once ice dam damage has occurred, prevention becomes critical. Attic insulation upgrades are the most effective prevention. Proper ventilation installation ensures cold attic temperatures. Air sealing prevents warm air escape.
Annual fall inspections assess your roof's readiness for winter. We check insulation depth, ventilation adequacy, and flashing integrity. We look for areas vulnerable to ice dam problems and recommend preventive measures before winter arrives.
Regular roof maintenance, gutter cleaning, and downspout clearing prevent water pooling that worsens ice dam formation. In severe cases, heated cables installed along roof edges prevent initial ice formation.
Don't Ignore Ice Dam Warnings
If you're seeing water stains, condensation, or icicles forming on your roof edges, don't ignore these warning signs. Ice dams represent serious threats to your home's structural integrity and interior conditions. Professional assessment and intervention prevent catastrophic damage.
