Patching a TPO roof
We have a couple of small holes in our TPO roof that might have been poked in by a branch or something. What sort of patch should I use?

Probably dicor. Our insurance company replaced the roof for very minor damage visible from the ground

I've heard of dicor but I don't think I've ever seen any. Is it a liquid or a film or sticky tape or what?

It's a caulking compound made for roof sealing.

GE Silicone II caulk will stick to it and prevent
any leak. I've used it and it works.

Is Dicor significantly different than the self-leveling sealer I used on the rubber roofs of my previous RVs? Is still have some of that.

Do you have a name for this material?
I would recommend getting a fresh tube of Dicor, clean the areas well and apply on each area. While you are on roof need to fully inspect all penetrations they may need touched up also with the Dicor.
Roofs need to be inspected yearly at a minimum. Caulk fails and water damage will destroy your rig.

This is the self-leveling stuff I used on my rubber roofs. Is it substantially different than Dicor?

Bloodyhell,
do not use the parbond on the tpo, it does not bond to it. You must use the 2 part dicor-part 1 is a cleaner/primer, part 2 is the sealant. Plan to go over the other penetrations at the same time as an opened tube of dicor has a short shelf life after opening, no matter how well you plug the end. At least that way you can get your money's worth, again make sure the primer is used before applying.
