Master Flash

Roof pipe flashings designed for residential roofs covered with tar paper shingles, cement, or ceramic tiles.

  • Made of high-temp silicone with soft aluminium base, these flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light
  • 4 sizes to fit 0” to 18-1/2” (0- 469 mm) diameter pipes
  • Square base
  • The built in 20º pitch allows adaptability to almost any roof pitch, including a 45º one
  • Installed by sliding down the pipe
  • Perfect for sealing elements like pipes, cables, and canals
  • The soft aluminium base fits easily to most residential roof profiles regardless of pipe location
  • The pull tab design and easy smooth tear grooving is intended to eliminate razor knives and allow for a circular hole
  • Sleeve flexibility accommodates vibration and pipe movement caused by expansion/contraction
  • Cut lines clearly marked to allow for easy installation for multiple pipe sizes
  • Temperature resistance: -74°C to 225°C continuous (+260°C intermittent)
  • Ozone resistance: 70 hour @ 500 pphm
