The broken part is just a cover to mate the pipe to your roof. Most hardware stores will carry something you can use for a replacement. Search for “vent pipe flashing”. Be careful when you remove the existing caulk to not damage your roof membrane. Then use appropriate RV caulk for the replacement. I like self-leveling Dicor for horizontal surfaces. Do not use silicone caulk.
It looks like the vent. I had something similar on mine
It feels like it could just be a cover of some sort. I’m still new to this so I had been reluctant to just teat into it without understanding what’s going on.
Source: Can anyone tell me what this piece is that is broken? Membrane or new vent?
