2nd floor above garage hot

2004 house we just moved into that has a media room above garage. Problem is the room stays 5-10 degress hotter since it's over the garage and has little attic space. What are the best ways I could 1)reduce heat coming thru floor from garage, and 2) insulate/rad. barrier the attic space.
Now is the time to tackle this since it's cooling down a bit.
Thanks.

Foil radiant barrier as long as you have vents is something you could add to the attic.

I used atticfoil.com but there are many others.

foil type RB only has about a two year working life.

We had the same setup in Houston and it worked great. Ive heard the dust opinions from both sides of the fence. Very little if any dust gets on it when it is stapled to the rafters.

I know from experience that it has worked for me. At $100 even if it only worked for one season I made my money back.

Yes airman, it's ducted correctly and gets cool when air is running. It just takes a little longer and the rest of the upstairs rooms are cold, while media room is just cool. Looking into ridge venting the area, attic RB and garage RB. I know I need RB on the back of the garage doors, but wondering if an RB paint would work on the garage
ceiling also? Is there anything available for such an application?

Yes the paint is the best way to go on existing homes.
