Description
ASTM Standard Anti-slip Roofing waterproof synthetic underlayment material
Synthetic underlayment is typically made from woven or spun polyethylene or polypropylene, and it comes in a variety of different thicknesses to suit your needs. These typically weigh a lot less than traditional roofing felt, and many products have layered design. Materials and design mean that synthetic underlayment is not only lighter than traditional roofing felt, but also much tougher, plus it comes with added features like anti-skid upper and lower layers to make installation and traction easier.
The lighter weight and higher coverage isn’t the only reason why synthetic underlayment is easier to install. It’s also less prone to tearing or wrinkling, and when fastened in place properly, it’ll stay in place against wind whereas felt may lift. This means less hassle before the roof goes on.

Features
1. Water Resistance: Synthetic underlayment is highly water-resistant, providing an additional layer of protection against leaks and water damage.
2. Breathability: Synthetic underlayment is often breathable, allowing moisture vapor to escape from the attic space, which can help prevent mold and mildew growth.
3. UV Resistance: Many synthetic underlayment products are designed to resist damage from UV exposure, providing prolonged protection to the roof structure.
4. Slip Resistance: Some synthetic underlayment products have textured surfaces that provide better traction for roofers during installation.
5. Fire Resistance: Synthetic underlayment may offer better fire resistance properties compared to felt paper, providing an additional layer of safety for the roof.
Application
1. Residential Roofing: Synthetic underlayment is widely used in residential roofing projects, providing an additional layer of protection against water infiltration and enhancing the overall durability of the roof.
2. Commercial Roofing: In commercial roofing applications, synthetic underlayment is favored for its lightweight properties, ease of installation, and long-term durability.
3. Metal Roofing: Synthetic underlayment is an excellent choice for metal roofing installations, providing a protective barrier between the metal panels and the roof deck.
4. Underlayment for Solar Panels: Synthetic underlayment is suitable for use as an underlayment for solar panel installations on roofs, providing a durable and water-resistant barrier.
5. Roof Repairs and Re-Roofing: Synthetic underlayment can be used in roof repair projects and re-roofing applications to replace old or damaged underlayment with a more durable and long-lasting alternative.
Overall, synthetic underlayment is a versatile roofing material that can be used in a wide range of applications to enhance the performance, durability, and longevity of various types of roofing systems.
