Roof Leaking in Vinyl All Season Room

Hello group,
I am trying to resolve a particularly stressful situation and would appreciate any thoughts. Last fall we had a vinyl all season room built on the back of our cedar sided house, underneath a second story deck. Some might call it a patio room or sun room, etc. Since it was finished the roof has leaked during heavy rains. Apparently the builder assumed that the house was water tight when he built it. Consequently, the roof header of the all season room, or where the roof system joins the existing cedar siding on the house, was not flashed. It was simply screwed to the outside of the cedar siding, and caulked along the top seam. Somewhere above the roof of the patio room water is getting behind the cedar siding and coming out inside the all season room in three locations. This was probably happening before the all season room was built but not noticed. The builder has been out twice to caulk seams in the roof, but now the builder is starting to take the position that it's my problem to deal with, and that they are done with the situation. Was I wrong to expect that when I signed the construction contract that I would be given a water tight room? Was I wrong to expect that the builder would take care to analyze the situation, anticipate possible problems, and take appropriate measures? When I asked the salesman on two or three separate locations, what happens if the room were to leak, I was told they would take care of it until it was fixed. I did NOT ask specifically how the room would be flashed, waterproofed, etc. My thoughts are this: Not flashing the roof header was a bad idea. Also, I realize that the problem is likely originating somewhere outside of the scope of the builder's immediate control. But shouldn't he be involved in the effort here to make this room water tight? I would love to hear any opinions on this matter. Thanks for your time, Jason

You said this: "Somewhere above the roof of the patio room water is getting behind the cedar siding and coming out inside the all season room in three locations. This was probably happening before the all season room was built but not noticed."
Translation: You want to hold the builder responsible for a problem which existed before he touched the job. And, even if it began AFTER the sun room was installed, how is it the builder's problem? It's originating elsewhere.
If I were you, I'd find a mechanical engineer and pay him/her to look over the situation.

Actually I would not consider the builder responsible for the leak, because as you said it existed (probably) before he started his work. If the culprit were an improperly installed door frame above the all season room roof, I would surely not expect the builder to buy me a new door and install it properly. My disappointment is that it appears he did nothing to stop water from entering the room other than apply a bead of caulk to his roof ledger. Not being a construction guy and knowing what typical construction methods are, that just doesn't seem lke enough effort to assure the room would be water tight. Jason

=====================
Somebody else mentioned getting your town's inspector to look over the situation. That's the first call you should make on Monday morning.
It's possible the builder did you a big favor by alerting you to a much bigger preexisting problem. But, if you're getting water behind the shingles (possible explanation), I'm at a loss to understand how you could've missed it.

Thanks for all the input so far. It seems I should definitely look into the code/permit/inspection situation. The builder was responsible for securing proper permits, and I know there was at minimum an inspection for the foundation. Beyond that I can't say if there were any other inspections, or if any other inspections are even required by the local authorities. I'll certainly find out.
Let me pose this question. If you were adding a room on to your house, how would you treat the area where the roof of the addition connected to the existing house? I suppose it would vary depending on the facade of the existing structure. In my case it's cedar siding. I'm just trying to get a feel for what typical construction methods would be in this case.

==============================
I have no idea. I'd do some research BEFORE hiring the contractor, so I'd know what to ask.

I'm just telling you the truth! I have no idea how I'd expect that job to be done with cedar shingles. Sorry it's not the answer you wished for. With siding, it would be obvious: Pop off the siding, install flashing, reinstall siding.
For any kind of work on your home, you have to think about what could go wrong, and then shop for contractors based on how they propose to avoid the problems you're concerned with. You must be a young/new homeowner if you didn't think of these things beforehand.

If the problem happened before the room was built, it is your problem, not his. If he is part of the problem, different story.
If the lack of flashing is the problem, he probably should have taken steps during construction to properly flash it. From your description and statement that it may have been happening before I'm a bit unclear. Have you talked to someone else, maybe a roofer if that is where the water is originating?

No flashing? Isn't it code violation? Did you take out building permit? Caulking is temporary patch work I'd say even if it stops leak. I have a 4 season sun room one in the front above the garage, one in the back extended from family room. No leaks. My house is 2 story as well.

Start with the city inspector that signed off on the job, and approved it as to code. Your leak description was not really clear to me.
