OATEY 14056 5.5 in. – 11.5 in. Master Flash® 14 in. x 14 in. Base Roof Flashing

The Oatey 14056 Master Flash handles pipe diameters from 5.5 inches up to 11.5 inches. The EPDM collar is trimmed down to the pipe you are flashing, so one part covers that whole range rather than needing a size-specific boot. If your penetration is smaller than 5.5 inches, you need a smaller Master Flash; the collar can only be cut larger, not made to seal tighter than its minimum.

Yes. The 14056 Master Flash is engineered for profiled roofing systems, and the pliable base conforms to ribs, corrugations, and standing seam contours at any roof pitch. That is the main reason to pick this style over a rigid lead or galvanized flange, which only seats properly on a flat deck.

The base measures 14 x 14 inches, which sets how much roof area the flange covers and how much room you have to land screws outside the penetration. Confirm that footprint clears any adjacent rib, curb, or seam before you cut the hole.

The collar is non-fading EPDM and the base material is pliable, so it won't crack or break with thermal cycling and roof movement. That is the practical difference from a lead boot, which stays sealed but gets torn open by animals and foot traffic, and from cheap plastic boots that go brittle under UV.

Order it as Oatey 14056. It weighs 1.45 pounds, light enough to carry several up a ladder in one trip when you are standardizing penetrations across a building.
