OATEY 11911 – Frequently Asked Questions

1) Will the Oatey 11911 roof flashing work on a pitched roof, and how steep can it go?
The 11911 No-Calk flashing slides over the vent pipe and works on roof pitches up to 45 degrees. Above that, it is the wrong part for the opening.
2) What size vent pipe does the Oatey 11911 flashing fit, and what is the base footprint?
It is sized for 4 inch vent pipe, with a 12 in. x 16 in. thermoplastic base. Check the deck opening and shingle course layout against that base before you cut.
3) Can I use this Oatey flashing on a hot-mopped or built-up roof?
No. The 11911 is not for hot-mopped or built-up roofs. Use it on shingle or comparable pitched roof systems instead; for a built-up or torch-applied assembly you need a metal or lead flashing rated for that application.
4) Is this Oatey No-Calk flashing rated for a Type B gas vent?
Yes, it is approved for Type B installations and rated for 180 degrees F continuous heat. That heat rating is the limit to check against whatever you are venting.
5) Does the Oatey 11911 need caulk or sealant at the pipe?
No. It is a No-Calk design, the rubber sealing collar does the seal against the pipe on its own. Do not apply paint or petroleum based products to the plastic base or the rubber collar, they degrade both.
6) What part number should I order to match the Oatey 4 inch thermoplastic vent flashing already on my roofs?
Order Oatey model 11911, the 4 in. No-Calk flashing with the 12 in. x 16 in. base. That single MPN is the whole item, there are no finish or size options to specify.
7) Will the black base and collar fade or crack after a few seasons of sun?
The base is rigid black thermoplastic described as non-fading and non-cracking, and the sealing collar is non-fading as well. For property managers repeating the same detail across a roof, that keeps the appearance consistent unit to unit.
