Those look like about #10 screws which is a relative small hole. A good dab of Dicor will completely seal the holes but if you like just put the screws back in and then seal.
Fiberglass, tape, etc just make a bigger area to seal and a much more involved process.

vacuumbed,
Curious about your future plans. I have an in motion dish DTV SD dish, with HD receiver and HD TV. May/may not step up to a roof non in motion HD dish. I have the room and carry a portable SD dish and could go for a portable HD dish.
Automatic roof HD dishs are $. Satellite guy said there are no good in motion HD dishes. We don't watch TV while driving anyway.

I'm going to remove it and sell it, along with the Kool-O-Matic kitchen fan.

Use a heat gun/hair dryer to warm it up and a plastic putty knife to scrape off. Acetone and cloth rags will help get the remaining sealant off. Take your time and don't rush scraping the material off so you don't stress or damage the roofing material. Doesn't require a lot of heat. A hot day in direct sun may even be enough to soften it so you can scrape if off.
Try and get as much of the sealant off before you actually try and remove the dome so you don't risk damaging the roof.
Bingo! Thanks Dale. This advice helped me get the Kool-O-Matic fan off tonight. I keep a cheap hair dryer in my garage and it did the trick.

The first item to get removed from my roof tonight was that Kool-O-Matic fan. What a relief to get that thing off of there. 
The opening is 14 3/8" X 14 3/8". I'm deciding to just do a plain rv roof vent or maybe another rooftop A/C so I can have a cold air dump. The boltholes for this fan stretched out wide past the opening.

thats not required and is a messy waste of time.Simply fill holes with the bolts removed and seeko flex them and any wires holes end of story
Yep, there is always an easier way. I was only stating the BEST way to repair a hole in a fiberglass roof. I'm sure someone very lazy could patch anything with duct tape, or other type of sealant, and it will be sufficient. Of course, after awhile it will look like nothing but a mess of bolts, screws, and holes with duct tape or sealant over them all over the roof. It is never a waste of time to do a job right. It just matters if you, as the owner, will settle for a "patch job" or want to take the time to do the job right.

If you are filling screw holes or cable openings, go to West Marine or another marine supply dealer and get some "Marine-Tex" - a two part epoxy putty that is widely used on fiberglass boats.It will bond to almost anything and can be sanded after curing.
"What is seeko flex?" - I think the poster is referring to the Sikaflex brand of sealants/caulking that are widely used in the Marine industry and in some RVs.
There are similar products made by 3M. My favorite is 3M "5200" adhesive/sealent. It is a can be used to permanently fill openings or as a VERY strong adhesive. Note it is really permanent and you wouldn't want to have to remove it. There are less aggresive products available than "5200" if you wish. They are part of a "family" of 3M products widely used in the marine industry.

I just put Marine-Tex on the screw holes on the roof from the old sat dish, kool-o-matic, and the rear ladder. Now letting it cure for sanding.

I used a piece of 1/4 inch lexan and used 3m 5200 sealant around the edges. Did not want to use anything metal as it would cause rust streaks down the road and fiberglass is resin and matting is way too much work.
