Ice can cause severe roof damage through ice dams and accumulated weight.
Ice can cause severe roof damage through ice dams and accumulated weight.
Ice dam removal costs up to $4,000, with resulting leak repairs reaching $24,000. Heavy ice and snow combined can exceed your roof’s 20-pound-per-square-foot design capacity.
What New England Homeowners Need to Know:
- Ice Dam Formation — When warm attic air melts roof snow, water runs down and refreezes at colder eaves. This creates ice dams that trap melting snow behind them and force water under shingles.
- Structural Damage — Ice dams add concentrated weight at roof edges while preventing proper drainage, causing shingle deterioration, fascia rot, gutter damage, and potential roof deck failure requiring thousands in emergency repairs.
- Interior Water Damage — Trapped water from ice dams seeps through roof decking into attic insulation, ceiling drywall, and wall cavities. This leads to ceiling stains, mold growth, damaged insulation, and compromised electrical systems throughout your home.
- Ventilation Failures — Poor attic ventilation allows heat buildup that melts snow unevenly. Meanwhile, proper systems like Cobra Ridge Vents and MasterFlow Intake Soffit Vents regulate temperatures to prevent ice dam formation.
- Leak Barrier Protection — These membranes installed at the eaves during roof replacement prevent water infiltration through the roof deck.
- New England Freeze-Thaw Cycles — New England temperature fluctuations create repeated melting and refreezing that compounds ice dams. So, ice dam prevention systems are essential for protecting homes throughout harsh winter months.
- Professional Intervention — GAF Master Elite contractors assess underlying causes like inadequate insulation or poor ventilation. We’ll install effective solutions rather than temporary fixes that leave your home vulnerable to future damage.
