How to insulate a storage shed with a metal roof?

I live in Texas and it gets very hot most of the year. I need to the shed to be comfortable so it can be used as a workout room and to keep our dogs in. My fiance tried to insulate it and said "the glue won't stick to metal, it gets too hot and will melt". I don't know anything about this, but yahoo answers has helped many times before. So what is the easiest and most cost effective way to insulate the roof? We do have a heater/ac unit installed, and a fan but the heat just bakes through the roof

1. What was he trying to glue to the metal roof? If the roof has joists/rafters inside you can install rolled insulation between the rafters then follow up with drywall to form a ceiling.
2. What is he using glue on? Buy rolled fiberglass insulation, install it between the rafters and wall studs...paper side in. You can cover the walls and ceiling with drywall, OSB, plywood if you wish. You do realize that insulating your shed isn't going to make it much/any cooler don't you? You will need an air conditioner for that, but the insulation will help keep the AC in.
3. First, paint that roof white. (It will make a difference.) Then fiberglass between the support rafters. There are wire rods sold that will hold it in place.
4. Use a double bubble reflective insulation. Install it on the inside against the rafters. This will create an airspace which will also help to insulate the shed.
