Masterflash®-Square Base Flashing
- The Masterflash® is a quick and easy way to flash a penetration coming through a metal roof.
- The clearly marked diameters on each flashing allow the Masterflash® to accommodate a range of sizes. The marked dimensions also allow for easy sizing to fit each individual application.
- Available in black EPDM and red Silicone, all flexible materials, the Masterflash® is resistant to ultraviolet rays, cracking & weathering.
- The aluminum base on the upper lip of the Masterflash® is corrosion resistant and allows the flashing to conform to any panel configuration and/or roof pitch.
