Should I insulate my garage attic? (self.homeimprovement)

So it’s currently 100 degrees F in my garage today. I’m sure it will only get worse as the summer goes on. I added some of those insulated garage door panels, but I don’t think they did anything.

Now I’m wondering if I should add fiberglass insulation to the attic space above the garage. Would this help, or just lock in the heat? Would using a radiant barrier up there work better?

I have the same problem with a different setup. Half finished walls. Nothing up except the roof. No insulation on walls or ceilings. 15 degrees hotter than outside.
Lack of insulation on roof and vents that are kind of blocked by the finished walls is my issue.
Solutions I've thought about are putting a vent up high, by the ^ of the roof. Putting a fan near that. Stapling insulation to the joists, just under roof, to keep some of that heat out.

Out of left field solution: get a heat pump water heater. It will be a lil loud tho.
