Master Flash

Roof pipe flashings designed for square vent retrofit applications where a standard pullover flashing cannot be assembled. Perfect for sealing pipes and cables and ideal for watertight sealing around installation elements and ducts that penetrate the roof slope (i.e., ventilation pipes, solar ducts, chimney flues, electric cables and wires or other elements passing through the roof slope).

  • Made of EPDM rubber with soft aluminium, these flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light
  • 2 sizes to fit 2-1/2” to 5-1/2” (63 – 139 mm) diameter pipes
  • Square base
  • Installed from the side of the pipe
  • Easy-to-install snap rivets included with the flashing
  • Perfect for sealing square pipes and vents
  • The soft aluminium base fits easily to most metal roof profiles regardless of pipe location
  • Sleeve flexibility accommodates vibration and pipe movement caused by expansion/contraction
  • Easy installation with farmer screws
  • Cut lines clearly marked to allow for easy installation for multiple pipe sizes
  • Temperature resistant from -55°C to +100°C continuous (+135°C intermittent)
  • Ozone resistance: EPDM 70 hour @ 500 pphm
