FLASHINGS

Flashings are essential for creating a secure, weather-tight seal around penetrations such as electrical conduits and roof anchors. They prevent water infiltration, protecting both the roof and underlying systems from damage. By accommodating various sizes of roof elements, they are suitable for both new construction and retrofit applications. Proper installation of roof flashings reduces the risk of leaks, ensures compliance with building codes, and extends the lifespan of the roofing system.
