Repair and epdm roof

I'm moving a solar panel on my roof and that is going leave some screw holes in the epdm roofing. Hopefully that's the right acronym....anyway, it's rubber and not the TPO. What is the best repair tape and process? I'm finding gentle heat gun and putty knife does a pretty good job of getting the goop up.

Thanks!

  • I'm a belt and suspenders kind of guy when it comes to roof leaking. Cover holes with dicor and then cover with eternabond when dicor is cured.
  • Clean area with Acetone then apply Eternabond. I had to apply a little bit recently. :B

    Didn't know I caught a branch. We were having a lot of rain and all of a sudden water started pouring out of one of the LED lights on the ceiling. Next morning looked to find the carnaige, so good thing it was a sunny day!

    X2. If applied properly, Eternabond is a one time repair.
  • I would fill the holes with dicor then cover with a piece of Eternabond. I wouldnt worry about dabs of tape scattered on the roof, keeping out water would be my top priority.

  • Dicor in ample quantities: Dicor at Amazon

    That's most likely what you are scraping up now.

    One tube of the self leveling stuff. Our local RV parts guy was saying they like some other brand but I don't recall the name and Dicor is tried and true. You could use Eternabond but the would leave dabs of tape scattered around your roof.
