Also roof/shingle repair, usually right after a storm. Depending on where you live, there are actually extended sort-of families that will hit a town once a year, get hold of a bunch of shitty "your job is your credit" trucks, and run several scams all over town at once. The big ones are paint (which they water down and will quickly fade), roofing related stuff, and what's listed above. Then they blow back out of town and stay gone for a year or two.
