What are the two main types of materials used in weatherproofing single-ply roofing?

The two main types of materials used in weatherproofing single-ply roofing are thermoplastic and thermoset materials. Thermoplastic roofing membranes can be melted and remolded upon heating, which allows for easier installation and repair. They are known for their flexibility and resistance to UV light and extreme temperatures. Thermoset materials, on the other hand, undergo a chemical change during production that makes them rigid and stable once cured. These materials provide excellent durability and resistance to chemical exposure.

This combination of thermoplastic and thermoset membranes in single-ply roofing systems offers a balance of performance characteristics that effectively protect roofs from weather elements while allowing for versatility in installation and maintenance. This understanding is essential for selecting the appropriate materials when working on roofing projects.
