Ice and water shield is a critical roofing component designed to prevent leaks caused by ice dams, wind-driven rain, and snow melt. Installed along eaves, valleys, roof penetrations, and vulnerable transitions, this self-adhering membrane creates a watertight seal beneath shingles to protect New Hampshire homes from freeze-thaw damage. Prevent Ice Dams. Stop Winter Roof Leaks. Protect Your Home.
What Is Ice & Water Shield?
Ice and water shield is a self-adhering waterproof membrane applied directly to the roof decking before the shingles are applied. Unlike standard underlayment, it seals around nails and fasteners to prevent moisture intrusion when ice dams or heavy snow trap water along the roof edge.
In New Hampshire, building code requires ice barrier protection along heated eaves due to consistent winter snow loads and freeze cycles.

Frequently Asked Questions About Ice & Water Shield
Does Ice & Water Shield Prevent Ice Dams?
Ice-and-water shield does not prevent an ice dam from forming. It provides an additional waterproof barrier beneath the shingles to help protect the roof deck if snowmelt backs up at the eaves. Preventing ice dams may also require proper attic insulation, air sealing and roof ventilation.
Is Ice & Water Shield Included in a New Roof Estimate?
Before choosing a roofing contractor, ask where ice-and-water shield will be installed, which membrane will be used and whether valleys, penetrations and other vulnerable roof transitions receive additional protection. The written proposal should clearly describe the underlayment and moisture-protection system included with the roof installation.
What Is Ice & Water Shield?
Ice-and-water shield is a self-adhering waterproof membrane installed directly over roof decking before the shingles are applied. Unlike standard underlayment, the rubberized membrane seals around roofing nails and fasteners, helping protect vulnerable areas from snowmelt, ice-dam backup and wind-driven rain.
How do I know when it is time to replace my roof?
Most homeowners start thinking about roof replacement when shingles are curling, missing, stained, or losing granules. A roof may also be near the end of its life if it has repeated leaks, soft spots, or visible wear around valleys, vents, and flashing. Queen City Roofing helps homeowners understand the condition of their roof and choose a replacement option built for New Hampshire weather.
