Master Flash Residential Flashing Silicone Type is a unique flashing designed for residential use. This roof flashing is suitable for tiled roofs and has a built in pitch of 20 degrees, which allows adaptability to almost any roof pitch including 45 degrees. Three different sizes are available: Aluminium base 20″ x 20″, suitable for external pipe diameters between 3″ and 8″. Aluminium base 27″ x 27″, suitable for external pipe diameters between 8″ and 12″. Aluminium base 31.5″ x 31.5″, suitable for external pipe diameters between 11″ and 18″. The clearly marked designation of pipe diameters takes the guess work out of sizing. The pull tab design and smooth tearing system allows you to adapt the roof flashing to fit to the required diameter without the need for cutting. Please note that the flexible cone will be red – for black please see the EPDM type.
