OATEY 11536 – Frequently Asked Questions
1) What size service mast pipe does the Oatey 11536 flashing fit?
The Oatey 11536 is sized for 1-1/4 inch electrical service mast pipe. The self-sealing collar slides down over the pipe and needs no caulking, and the galvanized flashing itself is 1-1/2 inch.
2) Can I use the Oatey 11536 mast flashing on a hot-mopped or built-up roof?
No. The 11536 service mast flashing is not for hot-mopped or built-up roofs. It is also not compatible with petroleum based products or paint on the collar or plastic base, so no roof cement or asphalt-based coating on those parts.
3) Why does the collar come separate from the base on this Oatey service mast flashing?
On the 11536 the collar ships unattached from the flashing base, which is what makes it usable for electrical service mast work. The mast pipe is typically already standing, so you set the base to the roof and then slide the self-sealing collar down the pipe to seal it, instead of threading a one-piece boot over the top.
4) How big is the base on the Oatey 11536 and how much roof area does it cover?
The galvanized base measures 12.5 x 8.75 inches in 28 gauge steel, and the overall base size is listed as 18 x 18 inches. Plan your shingle course overlap around that footprint so the upper edge tucks under the course above.
5) Do I need caulk or sealant to install the Oatey 11536 around the mast?
No sealant is needed at the pipe. The collar on the 11536 is self-sealing and compresses as it slides over the mast. Keep petroleum based sealants and paint off the collar and plastic base entirely.
6) Is the Oatey 11536 mast flashing galvanized steel or plastic?
Galvanized steel, supplied unfinished, with a plastic base component that the no-paint and no-petroleum restriction applies to. It weighs 0.5 lb.
