What can i do to add more insulation in a addition in my house?The Roof is flat on this addition (no attic room for insulation there).Looks like it's only 4 or 5 inches thick, starts from the inside with 1/2 inch drywall and the rest is plywood, and then that black sheeting on the outside.IS THERE ANYTHING MORE THAT CAN BE DONE TO ADD MORE INSULATION ON THE OUTSIDE?, (i can't do anything on the inside since the ceiling is already low) SINCE IN THIS ROOM IS VERY HOT, even touching the celing feels warm, PLEASE HELP!
You could have foam roofing installed over the existing roof covering. Look up "foam roofing" on the Internet.
You could build a pitched roof on top of the flat roof.
