I’ve been seeing a lot of houses with caulking on the upside of some of the flashings, including chimney. It looks sloppy and improper. For some houses I mention it, but what’s the deal on this? Should all these flashings be properly re-installed? (Obviously if there are moisture stains they should, but if there are no signs of previous leakage.) I have a few pictures, does this forum host pictures, or do I just provide links?
