I have an abandoned drain vent with the pipe removed and am wanting to somehow cap it without removing all surrounding shingles and re-shingling. Does any product exist that is made to cap an abandoned roof vent flashing? Thank you.
(edit a year later) For anyone reading this with the same problem, I adhered a plastic bowl on it for a year and it held up fine until I got the courage and knowledge to patch the hole and re-shingle the area. When I removed the bowl it was very brittle from UV.
