Staples on Roof Poking Membrane

I have a half a dozen or so staples that have been working their way out, and are pushing against the underside of the roof membrane. They are mostly above the long slideout, so I assume this area must flex a little more than the rest of the roof. I have been watching them from roof check to roof check, and they are to the point now that I think I should take care of them ....

My plan is to clean the area around the staple with mineral spirits, then carefully slit the membrane with a razor knife right over the staple. I will then remove the offending staple, and replace it with a stainless steel screw of the same length. I then plan to shoot a big dab of adhesive sealant - I will probably use 3M Marine 5200 since I have it laying around - and push the membrane back into place. I will then follow up with a 2-3" patch of Eternabond tape.

Anybody have a better idea?
  • Other than making sure the roof isn't soft, causing the staples to back out, it sounds like a good plan.
    Especially the Eternabond. It will not leak.

    Maybe someone sees a problem with this plan?
  • Why destroy the integrity of the roof membrane? Just use a strip of eternabond OVER the line of staples. No sense opening up the roof. The Eternabond will prevent the staples from going thru the EPDM roof. And if it possibly does, the Eternabond will then be the seal to prevent leaks. The staples have NO "force" pushing them up. they are just loose and the flex of the roof wood moves them up and down. Doug
