Ice Dam Water Damage Repair in St. John's: Attic Leaks and Ceiling Drying
St. John's Restoration Co. provides certified ice dam & attic water intrusion in St. John's, Newfoundland and Labrador. Water damage from ice dams, wind-driven snow, and attic infiltration, assessed, extracted, and dried with full insurance documentation for St. John's homeowners. We provide complete insurance documentation and bill all major NL insurers directly — including Intact, Aviva, and TD Insurance.
Ice dams are a uniquely damaging winter phenomenon for St. John's and Avalon Peninsula homeowners. They form when heat escaping from the living space warms the roof deck, melting snow that then refreezes at the cold roof edge. The resulting ice dam traps meltwater that has nowhere to go, and it backs up under shingles into the attic, ceiling assemblies, and wall cavities below.
St. John's winters compound this problem in two ways. First, the Avalon Peninsula's frequent freeze-thaw cycles create repeated melt-refreeze events throughout the winter season. Second, NL's persistent winds regularly drive snow directly into attic spaces through ridge vents, soffit vents, and around nail heads, saturating insulation and creating the wet conditions needed for mold colonization.
St. John's Restoration Co. handles the full scope of ice dam and attic water damage: from the initial moisture assessment and drying of wet insulation and structural sheathing, to mold inspection, antimicrobial treatment, and complete insurance documentation. We identify whether the damage source is ice damming, wind infiltration, or a ventilation deficiency and document the cause accurately for your insurer.
