No. 8 Masterflash Silicone Flashing  Ref: MFHS8

Roof Adaptability
Engineered for profiled roofing materials, Master Flash works on all types of roofing surfaces, including metal, plastic, tile, rubber membrane, and others.

Base Flexibility
You don't have to center the pipe on a high rib or in the flat. The base is designed to form a seal on any panel configuration and roof pitch, regardless of pipe location.

Sleeve Flexibility
Master Flash is pliable so it won't crack or break. It accommodates vibration, pipe movement caused by expansion and contraction, and snow-load movement.

Weather Protected
Made of EPDM or silicone, Master Flash is compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light.

Easy On-site Customization
Master Flash is easily customized with a sharp knife or scissors to accommodate a broad range of pipes and vent diameters. Field vehicles carrying 3 sizes can cover 90% of all normal installations.


It's a proven choice in universal flashings.
