During the Texas summer, I make sure to lubricate my garage door's moving parts with a high-temperature grease every few months, as the heat can cause the springs to weaken and the rollers to squeak. I also check the weatherstripping for cracks, since the sun's UV rays dry it out; a simple replacement keeps the cool air in and the dust out.
