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.

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
