Oops! I forgot that they should be small holes, and drilled first with a small bit, but later made them bigger with 3/16" bit (screws are 1/4" x 2")!
I covered screws with a kitchen/bathroom caulk, and also, after putting the screws half way down, tried to spread GE Roof Cement

around them.
Do I have a chance to have leaks now, because the pilot holes were too big?
The other two things, I screwed up:
I've been in attic and measured a distance between PVC vent pipe and the closest rafter, but, when drilling the holes, I missed that rafter,
drill just touched an edge of it! I was thinking to drill another holes, but later decided not to: I would have to worry about empty ones.
But I still drilled two unnecessary ones, which was my second wrong thing done: base of a mast has 6 holes, and I made 6 holes in my roof,
but there are only 6 screws, and 2 of them are reserved for support arms!
So, I filled these holes with GE Roof Cement, but I don't know, is it good or not, maybe I should get 2 extra screws and put them in there?
I am still worried about my roof...
Any suggestions?
