How is the edge of mineral surfaced roll roofing sealed?

Mineral surfaced roll roofing is sealed at the edges primarily using lap cement. This method involves applying a special type of adhesive that ensures a strong bond between overlapping sections of the roofing material. Lap cement is particularly effective because it not only helps to anchor the edges securely but also creates a watertight seal, reducing the risk of leaks due to the exposure of seams to water and weather elements.

Using lap cement is essential in roofing applications, particularly with roll roofing, as it serves to hold down the edges, preventing them from lifting over time due to wind or thermal movements. This method allows for a clean application that contributes to the overall durability and lifespan of the roofing system.
