New Home Construction
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 rubberized asphalt membrane applied directly to roof decking before shingle installation. 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.
GAF Master Elite® Contractor and Owens Corning Platinum Preferred Contractor
Queen City Roofing holds two of the roofing industry’s top manufacturer certifications: GAF Master Elite® and Owens Corning Platinum Preferred. These credentials reflect ongoing training, high installation standards, and a proven track record of professional roofing work. They also allow us to offer enhanced manufacturer-backed warranty options on qualifying roof replacements, including stronger material coverage, select workmanship protection, and limited transferability for future homeowners.
Why Ice Dams Cause Roof Leaks in NH
Ice dams form when attic heat melts snow on the roof surface. The melted water refreezes at the colder eaves, creating a barrier that forces water backward beneath shingles.
Without proper ice barrier installation, this trapped water can:
Penetrate roof decking
Soak insulation
Damage drywall and ceilings
Cause mold growth
Reduce roof lifespan
