Filling Drill Holes in Fiber Glass Roof

My vote would be high temp two part epoxy. Let it over spread the hole some.I say high temp because the skin could fry an egg in the summer sun. For insurance you could put an Eternabond patch over over the finished repair.

Just 2 1/4 inch holes and nothing more?? Fill to over filling with plain old SILICON. Once it sets up your fine

can you get at the holes from the inside? that might change my mind on what to do.

I say epoxy also. If the holes aren't countersunk, you might think about putting a little countersink to them so the epoxy isn't going into a straight hole.

I removed the battered dish antenna from the fiber glass roof of my coach and now have two drill holes, roughly 1/4 inch in diameter, to fill. Does anybody have suggestions as to the best material to fill those holes with? Many thanks.

Thoroughly clean the area around each hole, fill them with anything and cover each with a 4"x4" Eternabond patch.

BTW sealing around the edges of Eternabond with Dicor: http://www.campingworld.com/shopping/item/dicor-self-leveling-lap-sealant-white/32125, is not a bad idea.

since I haven't gotten an answer yet I will "assume" that the area is accessible from the bottom. in that case I would properly rough up both the inside roof surface and the surface of a disk of fiberglass or some material that is waterproof. I would then epoxy small disks of that material under the holes. when done properly that will permanently "fix" the holes other than cosmetic issues. then I would take white bondo or similar material from a marine supply place and gradually fill in the holes, finish sanding to make level and spray with white enamel.
this will be largely unnoticeable and you won't have gobs of tape, etc. hanging on the roof.

I'd just shoot some self leveling Dicor into them.

Would all of those people recommending an extensive repair for two tiny 1/4" holes actually do all of that?

Take your caulking gun, a tube of silicon and a tube of Dicor on the roof with you. Squirt/force the silicone down the hole until level and then put a dribble of Dicor over it.

Let's look at fact your removing Sat dish. Never going to put back or mount something else up there???
Maybe silicon up the bolts and put them back in. Put a layer of silicon over. You should be maintaining roof once a year minimum, so you can reseal as necessary.
Then if you need a mounting place for something on roof...wahla!!

I would put 1/4 inch stove bolts in the holes and cover with self leveling Dicor.
