Master flash

Metal Roof Master Flash is a specialized roof waterproofing accessory designed to provide weatherproofing around various roof openings such as vents, chimneys and other exposed objects. It is a versatile and essential component of metal roofing systems, keeping these penetrations watertight and protected from the elements. Master flashes are typically made from a combination of durable materials such as EPDM rubber, silicone and aluminum, chosen for their ability to withstand UV rays, temperature fluctuations and moisture. Master Flashes from Metal Exterior Products have a flexible cone-shaped design with a flange that allows penetration and conforms to its shape. This design ensures a tight fit and is waterproof. They are usually secured around the walkway using built-in clamps or by screwing a flange to the roof. The clamps can be tightened to provide a secure seal around the penetration point.
