I think I may have a bathroom ceiling leak. I discovered a water stain all around the ceiling in our small bathroom, and a few weeks later noticed another water stain in the shape of a circle more than a foot in circumference about 6 inches in from the original water stain all around where the ceiling meets the walls. We had a plumber come in and he sawed a hole in the ceiling and found nothing leaked! We live near the ocean and the bay in New Jersey and were told that possibly the wind blew in rain. Could this really be the problem behind our bathroom ceiling leak?
