We just got our first real rain since we bought this house. I saw some water damage on the ceiling in my master bathroom. I assumed the roof was leaking. I got in my attic to look, the roof itself appears to be in great shape. The wood looked good, I didn't see any leaks or water damage anywhere. There were two metal tubes that appeared to be made out of the same metal that heating ducts are made out of. They go from the roof and run down to the precise spot where the leak is happening. I'm assuming that it's just not water tight on the roof where they poke through. Any clue what these things are or do? The likely hood that this is my issue? The cost I'm going to have to incurr to address it? Of course while I was up there I didn't think to take pictures. So the pictures are me standing on a chair pointing a camera into the attic.
