In colder climates, roof leaks are often caused by ice dams, which occur when snow melts on a roof, runs down to the eaves, and refreezes to retain water. If water seeps under the tiles, the roof deck may be damaged. In vulnerable spots like valleys and chimneys, wind-driven rain can force water under roofing materials. Understanding what does ice and water shield do is essential, as it provides a durable, weatherproof barrier to prevent water incursion. Wind-driven rain and ice dams allow water to penetrate your roof, causing costly leaks, structural damage, and mold growth. Stopping these leaks requires reliable protection.
What Is Ice and Water Shield?
Waterproofing the shingles and roof deck with Ice and Water Shield, a self-adhesive roofing membrane. Sticky-backed rubberized asphalt clings directly to the roof surface to create a smooth, water-resistant covering. Unlike standard felt underlayment, which is fastened by overlapping layers and nails, ice and water shield encloses fasteners and nails to prevent water from entering weak points. Stickiness helps it prevent roof leaks from ice jams and wind-driven rain.
Sealing Out Water from Ice Dams
Water frequently pools and backs up beneath tiles at the roof edge due to ice dams. The eaves and valleys, which are the places most vulnerable to ice dam damage, are usually where ice and water shield is placed. The membrane creates a continuous waterproof barrier that prevents water from penetrating beneath roofing materials because it adheres firmly to the roof deck. The ice and water shield serves as a second line of protection, carefully directing precipitation away from the roof as it tries to penetrate the shingles.
Blocking Wind-Driven Rain Intrusion
Rain caused by the wind can enter roofing systems by lifting shingles or by taking advantage of openings around vents and flashing. A strong, flexible barrier that precisely fits the roof’s surface, including intricate details like joints and corners is provided by the rubberized asphalt membrane. Because it is self-adhesive, it can firmly seal around fasteners and nails, preventing water from being driven beneath tiles in high wind. By preventing moisture build-up, this tight seal shields the interior and roof deck from harm brought on by extended exposure to water.
Durability and Long-Term Leak Protection
The purpose of ice and water shield is to keep its waterproof qualities over time by fending against deterioration from UV rays and temperature changes. Because of its longevity, the membrane will shield the roof for many years, lowering the possibility of leaks and the need for expensive repairs. Ice & water shield is a wise investment for homeowners wishing to protect their roofs from winter weather issues because it offers a dependable waterproof barrier in areas where ice dams and wind-driven rain are the biggest threats.
