OATEY 12959 – Frequently Asked Questions

1) Will the Oatey 12959 No-Calk flashing work on a 4 inch vent pipe without caulking?
Yes. The 12959 is sized for 4 inch pipe and uses a self-sealing collar that slides down over the vent stack, so no caulk or sealant is needed at the pipe. One caution: keep petroleum based products and paint off the collar, since they will attack the seal.
2) What roof pitch can this Oatey aluminum vent flashing be used on?
The stamped metal base handles pitch from 0 to 40 degrees, which is anything up to a 10/12 roof. Steeper than that and you need a different base. It is also not to be used on hot-mopped or built-up roofs.
3) Can I use this flashing over a Type B gas vent?
Yes, the 12959 is approved for Type B installations and the collar is rated for 180 degrees F continuous heat. That is what separates it from a plain plumbing-only vent boot.
4) How big is the base on the Oatey 12959 flashing, and will it fit under standard shingle courses?
The aluminum base measures 12 x 15 inches. That is the flashing footprint you have to work into the shingle courses around the stack, so lay out your course so the upper edge of the base tucks under and the lower edge laps over.
5) Is the aluminum base on the Oatey No-Calk flashing bendable to match my roof deck?
It is rustproof stamped aluminum, and it is made to be shaped by hand or with a roller so it conforms to the deck and shingle profile. The base ships unfinished aluminum, so it weathers to a dull gray rather than being painted.
6) Will the collar on this vent flashing fade or need repainting over time?
No. The collar is made not to fade, and it should not be painted at all. Paint and petroleum based products will degrade the sealing collar, so leave it as supplied.
7) How much does one Oatey 12959 roof flashing weigh for a bulk roof order?
Each unit runs about 0.55 lb with a shipping volume of 0.259, so a pallet quantity for a multi-family or re-roof job stays light. Handy if you are estimating freight on a large stack-flashing replacement across a property.
