Diamond Deck is a high-performance synthetic underlayment designed for residential roofing applications. It offers superior protection and durability, exceptional slip resistance and water resistance. It's easy to install, cut and size and is an ideal choice for custom roof designs. Diamond Deck is made from a unique polypropylene and polymer composite material, making it highly resistant to tears, punctures and impacts. This advanced material ensures that the underlayment remains intact and functional, even under the harshest weather conditions. The underlayment features a special slip-resistant surface that provides a secure footing for installers and contractors, even on steep roof pitches. This feature helps to ensure safety during installation and reduces the risk of accidents or injuries. The underlayment forms a water-resistant barrier that helps to prevent moisture intrusion and protects the roofing system from damage caused by water infiltration. This water-resistant barrier is essential for ensuring the long-evity and durability of the entire roofing system. The underlayment is designed to be easy to install, with a light-weight and flexible construction that allows for easy handling and positioning. Diamond Deck is also easy to cut and size, making it an ideal choice for custom roof designs.
