Synthetic roofing underlayment is a high-performance material used beneath roofing materials to provide an additional layer of protection against water infiltration. Unlike traditional felt underlayment, which is typically made from asphalt-saturated paper or fiberglass, synthetic underlayment is made from polypropylene or polyethylene, making it more durable and resistant to tearing, UV damage, and moisture.
The benefits of synthetic roofing underlayment over traditional felt include:
Durability: Synthetic underlayment is more resistant to tearing and damage during installation and throughout its lifespan.
Water Resistance: It offers superior water resistance, reducing the risk of water penetration and protecting the roof deck.
Lightweight: Synthetic underlayment is significantly lighter than felt, making it easier to handle and install.
UV Resistance: It provides better protection against UV rays, allowing it to be exposed for longer periods without degrading, which is beneficial during construction delays.
Non-Slip Surface: Many synthetic underlayments come with a non-slip surface, enhancing safety for workers during installation.
Longer Lifespan: It generally has a longer lifespan and can better withstand extreme weather conditions, contributing to the overall longevity of the roofing system.
Overall, synthetic roofing underlayment offers enhanced performance, durability, and protection for roofing systems, making it a preferred choice for many modern construction projects.
