I have a rubber roof and I need to run solar wiring from the panels to the combiner box. The length will be about 15' and I have small square plastic feet that you can stick on the roof and attach a zip tie through and then zip tie the cables to the roof. I also have the option of putting two screws through these plastic feet. I would like to avoid drilling additional holes in the roof for all the feet and I'm wondering if I can use the tape that's provided on the feet as well as dicor to secure them to the roof. My fear is it will only be secured o the rubber membrane and will this try to pick the membrane off the roof while traveling down the interstate at high speeds? I've seen one person do it like I'm describing on a Jayco forum and no one advised against it and they never wrote back after the install saying the rubber membrane ripped.... Thoughts?

You can skip the combiner box by wiring in series.

Can you Dicor the wires to the roof and eliminate the feet?

Eternabond tape and coat with Heng’s.

I have exactly what you propose to do, and have had no issues, but I am only on my second year with it. If I notice any lifting, I will use a screw in the cable anchor and more Dicor to hold the spot down.

I put the wires in the gray flexible plastic conduit (Lowes/HD) and used Dicor Self Leveling for the "glue" to hold it down seven years ago and still in place.

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'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.
