TPO roofs are a type of single-ply roofing system known for their heat-reflective properties and resistance to ultraviolet rays. The installation process involves heat welding seams to create a continuous waterproof membrane. This seamless installation method ensures superior protection against leaks and enhances the overall durability of the roof.
4. Ethylene propylene diene monomer (EPDM) roofs
EPDM roofs are made from a synthetic rubber material, offering superior durability and flexibility. They can be installed using three different methods: fully adhered, mechanically attached, or ballasted. The seams of EPDM roofs are sealed using specially formulated tape or adhesive, providing excellent waterproofing capabilities.
III. Assessing the Roofing Structure
A. Importance of structural integrity
Before the installation of a flat roof begins, it’s crucial to assess the structure’s integrity. This ensures that the building can support the weight of the roof and prevents potential issues in the future.
