Ice Dam Prevention & Damage Repair in NYC

Ice Dam Prevention & Damage Repair explained
Ice dams form when heat escaping from the living space warms the roof deck, melting snow that then refreezes at the cold eaves. The ice builds into a ridge that traps meltwater, which can be forced up under shingles and into the house. The lasting fix addresses the cause: air sealing the ceiling, adding or correcting insulation, and providing balanced attic ventilation so the roof stays uniformly cold. Damage repair covers what the water has already done, including replacing wet sheathing, shingles, flashing and gutters, and installing a self-sealing waterproof membrane at the eaves. This is separate from ice dam removal, which only clears existing ice.
Options and materials
Air sealing and insulation review
Locating and sealing air leaks at the attic floor and checking insulation depth so less heat reaches the roof deck.
Attic ventilation correction
Adding or correcting soffit, ridge or other vents so cold air flows under the roof deck and keeps it evenly cold.
Eave waterproof membrane
A self-sealing underlayment at the eaves and valleys that helps block meltwater that backs up under roofing.
Roof and flashing repair
Replacing damaged shingles, flashings, drip edge and rotted sheathing where ice and water have gotten in.
Gutter and fascia repair
Re-hanging or replacing gutters and repairing fascia or soffit damaged by ice weight and moisture.
Our process
- Inspect inside and outWe look at the roof edge, gutters, attic insulation, ventilation and ceilings to understand why ice is forming and where water has entered.
- Written estimateA free written estimate separates cause fixes (air sealing, ventilation, insulation) from damage repairs (roofing, gutters, interior-adjacent work).
- Dry out and open upWet materials are identified, and damaged shingles, sheathing and edge components are removed where needed.
- Correct the causeWe improve ventilation and coordinate air sealing and insulation work so heat loss to the roof deck is reduced.
- Rebuild the eavesNew sheathing, waterproof membrane at the eaves, drip edge, shingles and flashing are installed to restore the roof edge.
- Gutters and reviewGutters and fascia are repaired, the site is cleaned up, and we explain what to watch for during the next freeze-thaw cycle.
What affects the price
Extent of water damage
Minor shingle repairs cost far less than replacing wet sheathing, fascia and sections of roofing along the eaves.
Ventilation changes
Adding soffit and ridge vents or correcting blocked ventilation changes material and labor depending on the roof design.
Insulation and air sealing
Scope depends on attic access, existing insulation and the number of air leaks found in the ceiling plane.
Length of roof edge
Houses with long or complex eaves, valleys and dormers need more waterproof membrane and detail work.
Gutter condition
Bent or detached gutters may need replacement instead of re-hanging, which increases materials.
Roof age and type
Older roofs may be better replaced than patched, and some materials need special handling at the eaves.
