underwatervolcano Posted August 27, 2020 Share Posted August 27, 2020 Hey, just wanted a 2nd opinion. I got rid of what appears to be the majority (95%?) of the old sealant and butyl tape. What remains is the gray really really hard material from previous (or previous previous previous) owner. Am I good to begin installing my vent? Or should I scrape further? Any thoughts appreciated 🙏 For whatever reason the website won’t let me post photos on this so I will try as a separate comment in same topic.

linda s Posted August 27, 2020 Share Posted August 27, 2020 I'd do a little more scraping where I see it bumping up and then steel wool it all around gray areas. Put the vent in place then and see if it feels tippy at all and look for an even rise from roof all around. The butyl will fill and gaps easily then. Make sure you use enough so it squeezes out all around the edges when screwing down. Clean up excess with plastic putty knife straight up and down all around edge. Excess will peel right up then Linda S Quote Link to comment Share on other sites More sharing options...

I cleaned it up pretty good and feel it’s nearly ready for the butyl tape and sealant. Just wondering now if there’s any need to plug the previous screw holes that are empty now, because they don’t line up with the new roof vent. I saw on some video they skipped that part without saying anything about it. Is it unnecessary because of the butyl tape seal? Quote Link to comment Share on other sites More sharing options...
linda s Posted August 28, 2020 Share Posted August 28, 2020 I never resealed mine and they don't leak and it's been quite a few years. The butyl is stuck in there and plugs the holes just fine. Linda S Quote Link to comment Share on other sites More sharing options...

Just make sure it opens to the rear. Fixing stuff at midnight can be disorienting Linda S Quote Link to comment Share on other sites More sharing options...
