I need some help here. I have a friend who asked me to look over this for him. He has a bay window with a copper roof that is leaking. I spoted 2 possible reasons for the problem but wanted to see if I am missing something. The window was installed originally when the house was built 14 years ago. The window has leaked since the house was built, but only in slow steady rains like we get in the fall in our area. It doesn’t leak (or at least not that can be seen) when the rains are quick as with fast moving storms.
The 2 things I saw from looking over it was: 1) the flashing over the window does not appear to be installed properly and 2) the brick veneer does not have any weep holes at all anywhere around the house.
The roof originally had copper valleys which were leaking in the attic, but that has been repaired. He thought that may have been the problem. But I saw no evidence that could be the case. The second floor has no signs of water damage in the wall or aroung the fixed window above the bay window. I told him that in order for the roof to be causing the bay window to leak there should be water damage in and around the second floor window as well. It would take a very large quanity of water coming in to the house to cause that much water in the bay window. Thus it was more likely to be a problem with the copper roof installation or the installation of the brick veneer around the window or both.
The builder completely reworked the copper roof in 2001, but the leak persisted and the builder has refused to fix it.
Is there anything I am missing here?
