Ice dams are one of the most damaging winter roofing problems for Longmont, Colorado homeowners. They form when heat from your living space warms the roof deck, melting snow that then refreezes at the cold eaves — creating a dam that backs water under your shingles.
What Causes Ice Dams on Longmont Roofs?
The root cause is almost always inadequate attic insulation combined with poor ventilation. When warm air from inside your home leaks into the attic, it heats the roof deck unevenly. Snow melts near the ridge and flows down to the cold eaves where it freezes solid.
Damage Ice Dams Cause
- Water backup beneath shingles causing interior leaks
- Ceiling and wall staining
- Damaged insulation from prolonged moisture exposure
- Mold growth in attic and walls
- Damaged or detached gutters from ice weight
