OATEY 12849 – Frequently Asked Questions

1) What pipe size does the Oatey 12849 roof flashing fit?
The Oatey 12849 is sized for 2 in. pipe. The self-sealing collar slides down over the vent pipe and seals against it without caulking, so no sealant is needed at the pipe penetration.
2) Can I use this Oatey vent flashing on a hot-mopped or built-up roof?
No. The 12849 is not for hot-mopped or built-up roofs. It's approved for Type B installations and rated for 180 degrees F continuous heat. For a hot-mop or built-up assembly you need a flashing rated for that application.
3) What roof pitch will this 18 x 18 aluminum vent flashing work on?
Pitch range is 0 to 40 degrees, so it covers everything from a dead-flat deck up through a steep 10:12-plus slope. The soft aluminum base is stamped so you can shape and form it down to the roof plane on the slope you have.
4) Will this flashing rust or corrode on the roof?
The base is rustproof stamped soft aluminum, an unfinished mill surface. Keep petroleum-based products and paint off the flashing collar and the plastic base, both will attack them.
5) Do I need caulk or sealant to install this Oatey roof vent flashing?
Not at the pipe. The collar is self-sealing and slides over the pipe with no caulking required. Normal shingle lapping and fastening practice still applies to the base itself.
6) What is the exact Oatey part number for the 2 inch aluminum roof flashing with the 18 x 18 base?
Order Oatey 12849. That model covers 2 in. pipe with an 18 in. x 18 in. soft aluminum base, and it's a single part with no finish or size options to specify.
7) Is this flashing light enough to carry a pallet of them up on a reroof?
Each 12849 weighs 0.871 lb, so a crew can stage a bundle on the roof without much thought. Volume is 0.154, useful if you're planning truck space on a multi-unit job.
