I just did the same thing on my 2013 JKUR.
My advice is to either build a hoist on your garage ceiling (what I did) or enlist the help of a really good friend. I got mine off by myself, but definitely took a couple tries to get the home made hoist to balance right with the top on. Become familiar with the dual top pages in the manual (can get a download from jeep.com) that starts around page 200. Torx #40 on 8 screws on the top. Don't forget to unhook the electrical and washer fluid.
If you don't already have the brackets that attach the top to the roll bar under the velcro flaps, you'll need those. The top I bought off CL had the brackets attached to the top, but I had to go buy the torx #30 bolts from the stealership. Also, make sure you have the velcro straps to hold the bars down when in sunrider or all the way down.
One last thing, you might want to remove the floating nut receivers for the hard top screws once you have it off. The ones closest to the tailgate come right off after sliding them to one side, but the others are a little tricky. I left them on for a few days, but the rattling got to me eventually and I had to get the others off. Take a look at the ones that you pull off near the tailgate to see how you need to push/pull the others off. Basically, I had to pull the bracket towards the underside of the lip and then slide it towards the inside of the vehicle to clear the lip on the underside of the body. That really sounds confusing, but it might make a bit more sense once you get the back ones off and look at how they were secured to the body.
