In the van life community a lot of roof vents get Installed. Butyl tape is used between van roof and vent flange, however underneath the flange are ridges , I guess to better bite into the Butyl. Would it make a better seal to apply lap sealant under the vent flange before pressing it down on the Butyl?
My question about Butyl tape is the repair of a seam in a gutter.Caul doesn't seem to hold, maybe it's the expansion> The tape goes on the outside of the gutter, after it is clean and over 40 degrees (not too cold out) correct? thanks I appreciate it.
Butyl tape is too thick for gutter repairs. Gun grade butyl, sealant and rivets will be a better option. Just make sure that your gutters have a big enough lap that the butyl doesn’t squeeze out all over the place. On the inside of the seam I would cover it With standard gutter sealant
hello, I was thinking of also putting some rubber tape or something on top of the z purlin before the steel roof goes down for a thermal break...is this a good idea?
Yes a thermal break is a good idea but we would recommend using an 3/4" foam thermal break instead of rubber. Rubber has a higher conductivity than EPS foam.

What brand is that specific Butyl Tape and where is the best place to get it?
The issue video and the solution video are for two completely different types of metal roofs.
I thought the same thing. I wanted to see it applied to R-panel roofing.

No, the butyl Will flow around the ridges when it gets warm.
