I am trying to trouble shoot a leak on a tile roof. The customer, who recently purchased his house, called me out yesterday and showed me an area where his ceiling leaked water in his master bedroom during an unusually windy, heavy storm. He said he was able to collect more than a pint of water. The house, and roof, are only 13 years old. I went to the attic to look for water staining on the underside of the decking but was unable to locate any due to the spray foam insulation on the bottom side of the decking. I did locate a water stain on the top side of the sheet rock near the can light. There is also an ac unit with a drain pan not far away. I ruled that out since the water was coming in during the storm and it’s a little distance from the stained sheet rock. I did make note that the leak area is directly below a valley and sort of down hill from a flue pipe and plumbing stack. I climbed on the roof and I don’t see anything that I would believe to be the source of the leak. The location of the leak is about 3ft inside the outside wall about 6 ft or so up the valley in the pics.
My first thought is this storm was super windy and it may have pushed water uphill in a way it normally wouldn’t, but I don’t think that’s an acceptable answer for the customer. I’m also thinking, should I try to recreate the leak and try to locate it from the attic then. I’m just not sure what to do. I don’t have much concrete or clay tile experience, although I have been around roofing my whole life. Any thoughts or suggestions would be greatly appreciated. Thanks
