Leak Barriers - StormGuard

StormGuard® Film-Surfaced Leak Barrier

Help Protect Your Home From Wind-Driven Rain And Damaging Ice Dams With A Leak Barrier.

A Quality Leak Barrier Will:

Create a seal that helps keep water out at the most vulnerable areas of your shingle or metal roof (at the eaves and rakes, in valleys, around chimneys, etc.).

StormGuard® Leak Barrier will:

  • Help protect your home from costly wall and ceiling staining

  • Help prevent leaks due to water damming in your gutters, wind-driven rain, and, in the North, damaging ice dams

Good Housekeeping

Help Protect Your Home

  • The Codes Are Clear...
    North Area Protection against ice dams is required* at eaves wherever the January average temperature is 25°F (-4°C) or lower or where there is a possibility of ice forming in the eaves - i.e., the area labeled "North." †

  • But Be Prepared...
    Ice dams can still occur in areas where the average temperature is above 25°F (-4°C).

  • Reduce The Risks...
    If you are in an area that requires leak barrier protection — and there is a leak — you could be putting your insurance coverage at risk by not installing it!

* Check local building codes for specifications in your area.

Homeowner’s Best Choice

  • Looks Better...
    Fiberglass reinforcement helps resist wrinkling and buckling—lays flatter under shingles.

  • Meets Building Codes...
    In the North, where a leak barrier MUST be used. †

  • Peace Of Mind...
    Up to a Lifetime ltd. warranty when used on Lifetime Shingle roofs (See Details) , up to a 25-year ltd. warranty when used on non-Lifetime Shingle roofs (See Details) , and up to a 10-year ltd. warranty1 when used with other approved non-asphaltic roofing systems.2

† In the “North,” building codes require the use of leak barrier at the eaves.
