The base is designed to form a seal on any panel configuration and roof pitch, regardless of pipe location. Master Flash is pliable so it won’t crack or break. It accommodates vibration, pipe movement caused by expansion and contraction, and snow-load movemnet. Master flash is made of EPDM and compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light.

The flashing seems to be well made.
I am putting a new roof on my house and needed a way to seal around an existing electrical mast. This flashing device was the ideal solution to my needs. The flashing is split and has several pipe sizes to fit piping for electric masts.

It did what I wanted, but I could not get the snaps to work on the zipper. I had to use screws.
