Find the leak’s location on your ceiling as your first step and proceed from there. Once you detect its location, take a look at it from the outside to see if there are any missing items on your roof. If you see missing shingles, for example, you will know the area where the leak is coming from. If the location is hard to see, take a hose to your roof and spray around while someone on the inside checks to see if the leak resumes. This will allow you to find the location of the leak. It is also recommended that you check your attic for any openings or damaged connections to your roof, as this, too, can help you pinpoint where your leak is coming from.
