I have a bay window in my upstairs master bedroom and for the first time tonight it is leaking. It is raining outside and I can see the drops coming from the top of the ceiling over my blinds. The paint is peeling and it's very wet. I went outside to look, just to see if I could see something but there is nothing. My shingles seem ok, my eavestrough seem ok and the window seems ok.
The house was built in 2013 but I am not the original owner so I cannot say who installed the windows or if this has happened in the past and simply patched.
I'm very unsure who I would call for this issue, since from the entry point of the water it could either be the window seal or the roof. Also there is a lot of water now so I do not want this to persist. Any help you could offer would be greatly appreciated.
Thank you in advance.
It was typical of homes in 2013 to be built without drip edge on the perimiter of the roof. This often times lets water run off of the shingle surface, down between the eavestrough and fascia. This water then many times gets on top of the soffit, and into the home along the soffit.
Alternatively, you could inspect the window capping. If there is no top-side drip cap on the window, than water running down the siding can enter into the home at the top of the window, where a metal flashing should be that directs water to drip away from the home, and to not run down the window.
There is a third option in my mind, and that is that the roof just plain Jane leaks. Many times shingles can look appealing, but the method of installation is so critical. Roofing is like making a good salad. In theory its just greens and dressing, but go to the finest resturant and notice the lemon zest, capers, and finer oil and youll agree its more about how you do it. Many times shingles are installed with the "step" too small, or in some rare cases with no step at all. This can let water into the home, however so can a number of other roofing related issues.
Your best bet is to call a contractor who has experience with exteriors. Roofing is a great place to start, but its highly likely it is a combination of these issues of poor installation methods, and some "missing pieces" in your homes construction.

It is difficult to say one method without locating from where the water is leaking. Bay windows are manufactured as a single piece, so you can't take them apart. Panes of glass can be replaced in wood-frame bay windows, though you can't replace the glass in most vinyl-frame bay windows because the glass is sealed in place by the manufacturer. Because replacing a glass pane in a wood-frame bay window requires precision and accuracy, consult a professional window installer or a window repair specialist to help with the repair.
