What does a flood coat involve?

A flood coat involves the application of a heavy pouring of bitumen combined with aggregate. This process is integral to built-up roofing systems, as it provides a robust and durable surface layer that enhances the roof's waterproofing properties. The bitumen serves as the adhesive and waterproofing agent, while the aggregate, often made up of mineral granules or small stones, reinforces the surface, adding durability and protection against the elements.

This method is typically used in the final stage of roofing installation, where the flood coat acts as a protective layer that can withstand weather conditions, UV exposure, and mechanical damage. The aggregate also helps to reflect sunlight, which can reduce heat buildup and contribute to energy efficiency in the building being roofed. Overall, the flood coat is essential for maximizing the lifespan and performance of BUR systems.
