fiberglass roof wearing through

[Jim13]

I've noticed my caulking on our roof is looking rough and was thinking about scraping it off and reapplying with something new? But when I was looking around it appears as if the roof looks like it has worn thru at spots like little holes but not punctured? Any ideas and what to do to repair or an service center you can trust to fix, sand, and repaint in southwest Fl. Any thoughts?

Jim, Looks like what your seeing is a case of thin gelcoat wearing through, those pinholes are actually bubbles in the resin below the gelcoat. Not anything to get excited about if it's just a small area. The gelcoat is UV resistant, the darker resin areas are not . It doesn't sound like a re gelcoat is necessary, but you might want at least paint those areas affected, to prevent further damage from the sun. Good luck!

There is an excellent product called Seal-Krete that can be applied to fiberglass prior to painting. As the name implies it's a concrete and masonry sealer, but it works like a charm on fiberglass also. Use their original or heavy duty sealer. Its available at good paint stores. It bonds extremely well to fiberglass, stabilizes any chalking or porosity, and really holds paint. Make sure you dewax the surface prior to applying this or any other product. Good luck.
