Make your whole shop a swamp cooler: put a sprinkler on the roof. Keep it to a light mist so it evaporates on contact with the roof. That helps mostly if you have a metal roof but should lower under roof temps by a few degrees, which is gold when it get hot.
Damn that's a good idea. I've never thought to do that, but I'm going to try it now. My garage isn't insulated or anything, and has a shingle roof. That might actually help cool it because water will have more time to evaporate before running off than a steel roof. I bet a soaker hose at the peak would do the job nicely, and I could install a needle valve to control flow. I know I live in the frozen tundra of Canada, but it actually gets hot where I am. 38C (100F) in the shade is pretty standard for most of July and August, but it's also a pretty dry heat. When (if) I get to build my big dream shop, it will be dug into the ground behind my garage and I'll back fill against the concrete on three sides to help keep it cool.
