Flashing DWV on granular asphalt flat roof

| Posted in General Discussion on
I’m running a 2″ DWV pipe up through an almost flat roof (~1/12). The roof is granular asphalt (10 yrs, will be replaced in next year +/-). Because the DWV is within 10 feet of an operatable skylight, the pipe will extend 36″ above the roof.
What is an appropriate, cost-effective (will be removed in next year) means to flash the pipe?
Possibly Oatey 2″ Galvanized flashing https://tinyurl.com/y6o4gpfx with caulking on the underside near edges, nailed near edge into place and acrylic flashing and mesh on top of the edges?

Yes, the Oatley flashing will be fine. I'd run a bunch of poly under it, nail it down good then seal all the edges with poly.
The poly - is that some type of flashing tape or simple plastic?
Thanks Florida!
