Ice dams cause serious damage to shingles and gutters when left untreated.
Ice dams cause serious damage to shingles and gutters when left untreated.
Water trapped behind ice dams forces its way under shingles, compromising your roof deck. Shingle repairs alone can cost $130–$9,000, with roof leak repairs reaching up to $24,000.
Preventing ice dam damage starts with the right roofing system — not emergency repairs after the fact!
What New England Homeowners Need to Know About Ice Dam Damage:
- Shingle Damage Is Direct and Costly: Ice dams force water under shingles, lifting and cracking them over repeated freeze-thaw cycles. Shingle repairs range from $130–$9,000 depending on the extent of damage across your roof.
- Gutter Damage Compounds the Problem: Heavy ice accumulation pulls gutters away from the fascia under its weight. Gutter cleaning after ice dam removal costs $75–$400, but full gutter replacement adds significantly more.
- Roof Leak Repair Costs Escalate Fast: Water forced under damaged shingles penetrates the roof deck and interior structure. Roof leak repairs can reach up to $24,000 — far exceeding the cost of prevention.
- Ice and Water Shield Installation Is the Answer: Coastal Windows & Exteriors installs GAF-approved leak barrier membranes at the eaves as part of every comprehensive roofing system. This stops water intrusion at the source — before it reaches your shingles or deck.
- Energy Efficient Roof Shingles Add Another Layer: A properly installed GAF roofing system pairs energy efficient shingles with leak barriers and ventilation. Together, they reduce the conditions that allow ice dams to form and cause damage.
- Ventilation Reduces Freeze-Thaw Cycles: Proper attic ventilation lowers roof deck temperature, reducing the snow melt cycle that feeds ice dams. GAF’s Cobra® Ridge Vent and MasterFlow® Intake Soffit Vents work together to regulate airflow year-round.
- Emergency Removal Costs Add Up: Professional ice dam removal costs up to $4,000. Heat cable installation to prevent recurrence runs $500–$4,600 — costs that a proper roofing system eliminates from the start.
Protecting Your Shingles and Gutters From Ice Dam Damage:
Best Overall Protection: A complete GAF roofing system with ice and water shield installation at the eaves, energy efficient shingles, and proper ventilation — eliminating ice dam conditions before damage occurs.
For Existing Ice Dam Concerns: Professional removal addresses immediate damage. Removal costs up to $4,000 — a fraction of the structural repair costs that follow if ice dams are ignored.
Smartest Long-Term Investment: A full roof replacement with integrated leak barriers and GAF ventilation products removes the root cause of ice dam damage permanently.
