Reuse the hardware that held the antenna in place. Spread sealant on the threads and screw back into the holes. Then cover the heads with sealant. Use the left over sealant to reseal your bathroom sky light, vents, TV antenna, what ever else on the roof.

If the sat antenna is like mine, all you will have is a few bolt holes, If the roof is rubber, Dicor caulk (the non self levelling kind) works just fine for small holes.

Or you could use a 11x11" slab of Eternabond cut into 4 pieces (5.5 by 5.5" each)

Either method should work great.

X - 2! That way it is done right.

Bingo. Just put the bolts back in the holes with sealer and call it good. Its on the roof, no one can see it. Beside a couple of bolts into the roof isn't going to look bad. You never have to worry about the repair going bad or cracking. Simple solid solution.

Three (3)years ago I removed the same hardware from my roof and repaired the holes with Eternabond.
Cut small 4" square pieces and place over screw holes and use larger pieces where coax cable penetrated roof membrane.
ETERNABOND is the best and probably the easiest to use!

And that's exactly what it's meant for. No sanding and grinding with a finish that may well crack, and looks far worse than a flat white patch. Eternabond simply won't come off prepped correctly.

What's the best way to get this white paste off? Is there a chemical that will soften it or does it just have to be scraped off?

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.
