A crucial element in modern roofing systems, this product serves as a protective layer installed directly onto the roof deck before the application of primary roofing materials like shingles, tiles, or metal. Its primary function is to provide a waterproof barrier, safeguarding the structure from water damage caused by rain, snow, or ice dams. This underlayment is engineered from synthetic materials, offering enhanced durability and performance compared to traditional felt options.
The use of this specific type of underlayment provides several advantages. It offers superior tear resistance, preventing damage during installation and from exposure to weather elements. Its synthetic composition makes it resistant to mold and rot, ensuring long-term performance and protection. Furthermore, it often features enhanced UV resistance, allowing it to withstand prolonged exposure to sunlight during installation without degradation. The historical context lies in the evolution from traditional asphalt-saturated felt, which, while functional, lacked the durability and lifespan of modern synthetic alternatives.
