Roof underlayment is a critical component in any roofing system, acting as a protective layer between the roof deck and the final roofing material. In India, where diverse climatic conditions can pose significant challenges to roofing structures, high-quality roof underlayment is essential for ensuring long-term durability and weather resistance. It provides an additional barrier against water infiltration, wind-driven rain, and other environmental factors, enhancing the overall performance of the roof.
