Saint Paul's Roof Killers: Ice Dams, Freeze-Thaw, and Hidden Damage
Saint Paul's winters hit roofs hard with ice dams. Snow melts on a warm day, refreezes at the eaves overnight. That blocks water, forcing it under shingles into your attic.
Ice Dams: The Silent Invader
Picture this: gutters overflow with chunky ice. Inside, stains spread across ceilings. One unchecked dam can cost thousands in water damage repairs.
- Heavy snow buildup on south-facing slopes speeds melting.
- Poor attic insulation traps heat, worsening the cycle.
- Result? Rotting sheathing and mold you can't see.
Freeze-Thaw Cycles: Cracking Your Defenses
Our endless thaw-freeze swings expand and contract roofing materials. Shingles curl. Flashing cracks open.
Granule loss exposes asphalt to UV rays next summer. Nails pop loose over time. Your roof ages five years in one brutal season.
Hidden damage lurks worst of all. Wind lifts shingles slightly, rain sneaks in. Attic leaks mimic plumbing issues until joists rot through.
