I'm going to "third" the suggestion for Eternabond. You can cut just a few strips to stick it down in a few places and you'll be good to go. Mine has been attached that way for about 15 years.

And I did in fact also use the Hengs roof coat a couple years ago over the top of all of it.

I like the 3M VHB taped tie wrap holder and a tie wrap, try it BEFORE you add sticky stuff like Eternabond.

Eternabond is great and stick like crazy. But the idea of having a tube to protect the cables is good too. Plus if you need to add or upgrade cables, you can feed new in without messing with unsticking them from the roof. Maybe a gob of sealant or a gland at each end to keep out water, bugs, etc.

Unsticking VHB tape is super easy!

Mineral spirits poured next to it and (like a spatula) push under the sticky pad like a pancake a few times...Pop! ——They pop right off!

Nope, with a excellent UV resistant PV cable, VHB tape is way way strong enough. Need new cable, clip wire tie (leaving stuck pad) change wire, add new wire tie... Done.

Jeeze, we are talking wires, not friggen panels.

Some Dicor dabs, some Eternabond tape. Combiner boxes are rarely needed, and best avoided IMO.

freetheheel, no I don't have pictures. But yes, it is a rubber roof. Several years ago I coated the rubber roof, removed the panels and simply took a heat gun to the Dicor "glue". The conduit pulled up with no problem, took a plastic putty knife and removed the remaining Dicor. When I completed the coating, reinstalled the panels, and put a dab of Dicor self leveling sealant to hold the conduit back down. Thye conduit is called "Liquid Tight". Cheap and easy to use.

That is kind of what I was thinking and I'm glad to hear you've had success. I don't want to leave the cables exposed to the elements and have been wondering what to enclose them in. I take it your roof is rubber as well? Do you have any photos?

Thanks for all the replies from everyone.


I did this a few years ago with the wiring and coax for my sat dish. It is still holding up fine. BUT, be sure to coat the plastic conduit or the UV will make it so brittle it will fall apart over time. I coated mine with Hengs roof coating. Chuck

chuckbear, that is surprising to hear of that with Liquid Tite. We used a lot of it before I retired from the telco company. Also most central A/C installers here in Arizona use it between the breaker box and the A/C unit.

I don't know why you would want to use it. But most liquid-tite will be UV rated. Just like most solar cables are UV rated. Which is why pulling the UV cable through a UV liquid-tite seems like nonsense to me. If you use it, check the specs.
