When it comes to protecting your home, the roof is your first line of defense. While shingles provide an essential layer of protection, they aren’t always enough to prevent leaks, especially in areas prone to extreme weather conditions. That’s where a leak barrier, also known as an Ice & Water Shield, comes in.
What is a Leak Barrier (Ice & Water Shield)?
A leak barrier is a self-adhering waterproof membrane installed under the shingles in vulnerable areas of your roof. It’s primarily designed to prevent water from infiltrating your home due to ice dams, wind-driven rain, or water buildup from heavy storms. Leak barriers are typically installed around roof edges, valleys, chimneys, skylights, and other penetrations where water may accumulate or flow.
How Does It Work?
The leak barrier serves as a second line of defense, sitting directly on your roof deck and adhering to the surface. It forms a waterproof seal that helps stop water from seeping through cracks, nails, or seams in the roofing materials.
Ice Dams: In colder regions, ice dams can form along the roof's edge, causing water to back up under the shingles. Without a leak barrier, this water can find its way into your home.
Wind-Driven Rain: High winds during storms can force rain under shingles. A leak barrier prevents this water from damaging your roof structure.
Heavy Snow or Rain: During intense weather, the volume of water can overwhelm traditional roofing materials. The barrier acts as an extra layer of waterproofing.
Materials Used in Leak Barriers
Leak barriers are typically made from a rubberized asphalt material that is self-sealing. This flexible material allows it to conform to irregular surfaces, creating a watertight seal even around nails or staples. Some advanced leak barriers may also feature a reinforcing layer of fiberglass or other materials for added durability and protection.
Why Is It Important?
Prevents Costly Water Damage – Water infiltration can cause significant damage to your home’s structure, including rot, mold growth, and compromised insulation. A leak barrier ensures that even if water bypasses your shingles, it won’t reach the interior of your home.
Prolongs Roof Lifespan – By preventing leaks, the barrier helps extend the lifespan of your roof and the materials beneath it, keeping your home protected for years.
Peace of Mind During Storms – Whether you’re dealing with ice buildup, heavy rain, or high winds, a leak barrier gives you peace of mind knowing that your roof is ready to handle whatever Mother Nature throws at it.
