Oatey® invented the flashing industry nearly 100 years ago. Oatey offers the Master Flash® for commercial applications, along with a variety of specialty items including Rain Collars and Mushroom Caps.
How is a rain collar installed?
After the correctly sized collar has been selected; you will apply a 100% exterior or marine rated silicone caulk to the top of the existing rain collar attached to the roof flashing, and also to the underside of the new rain collar. Slide the new rain collar down over the pipe to the top of the existing collar. Press the new collar down with enough pressure to seal the two together without collapsing the seal around the pipe.
What are the maximum temperature rating for roof flashings?
Oatey Master Flash and Retro-Master Flash are rated for continuous temperatures up to 212°F. All other Oatey flashings are rated for B venting, which are continuous temperatures up to 180°F.
Can the Master Flash flashing be installed on a shingled roof?
No. The Master Flash and Retro-Master Flash are specialty flashings designed for engineered roofs.
