OK, I just spent 2 hours googling because I didn't want to annoy youse guys by asking too many questions. There is way too much info out there and I don't know who to believe. I trust you guys.
I have about 10 unused screw holes in my roof, and another dozen holding down some old but useful tech. I want to plug the unused ones and seal the useful ones.
On another thread, DrewE said, 'epoxy mixed with a filler of some sort,' for the unused ones. So I was trying to figure out what filler. Hoo boy.
For the useful ones, should I remove the screws, scrape out the old caulk, and replace the screws, bedding in dicor? 551?
Get some Dicor caulk and squeeze a bit into the hole and let a bit ooze out onto the roof. Now, screw in a screw of the appropriate size or even a tad bigger. Caulk over the top of this and you have a nicely sealed hole that will last for many years. Check the caulk every couple of years and add a bit more if necessary.
