To locate a roof leak you need a ladder and a flash light. Take your ladder and stand it under your main hole. Open the main hole lid and go through into the attic (another person should hold the ladder as a safety issue). Walk /crawl to the area which is leaking (be careful not to step over the ceiling). When you get to the leaking area, first look for water or water stains over the ceiling. After you find water over the ceiling, then look up and find where the water is coming from. That’s it you found it.
