I am looking for advice from someone who knows about these kinds of things.
I have pictures and would really appreciate it if you could tell me what you think the problem is or if it is even a problem. The roof on my 1 year old house and vertical bumps and just today i found water dripping on siding. the pics from the roof are from last year when rood was 3 months old. The company told me this is normal. Please let me know what you think.

The roof looks terrible. If this is normal I'd hate to see abnormal. The lines appear to be at the ends of plywood sheeting-however, they are at less than 8' apart. What is the truss(i assume) layout of this roof?
The water may be more simple to answer. Was the vent shown for a dryer or bath vent? If dryer, almost looks like hot air was exhausted and the resultant fog made from a dryer exiting into sub 30's temp condensed on the soffot and somewhat on the siding, then dripped down.

I think the truss layout is 24" and the wrinkles are at 8' I conclude this by counting the shingle tabs. There are about 7-1/2 tabs or less, wrinkle to wrinkle. With metric shingle sizes, that would be eight feet.
I had also considered that this might be wrinkles in 30# underlayment, but it is too regular, and more consistant with sheathing sizing, IMO.
Of course, if like someone else mentioned, the sheathing was not nailed off very well, it could be both too. That could also account for the wavy surface in some places.
I would not be surprised if this was barely nailed sheathing. In my years roofing, I probably crawled up onto well over a hundred roofs that the GC had proclaimed to be ready to shingle, only to find that the plywood was only tacked, or had been nailed off by amateurs who couldn't begin to hit the framing with their nails.
Generally, I would nail it off and charge extra for the service before starting to shingle. Sometimes, in a larger project, the carpenters would still be around someplace and I could round them up to teach them how, and other times,when it was pure jerks building it, I would move on, and leave a message to call me for shingles when they got ready. Some shingle layers would just go ahead and apply.
Point being - that it is not uncommon for some builders to let this get by.
Another thought I had on this though, was that I have seen things like this a dozen times where it was the homeowner's error causing it.
Couple of times it was because somebody had read or heard that by disconnecting the dryer hose and letting that heat go into the attic instead of outside, they could save on their energy bills, only to learn that repairing all that mold damage was mucch more expensive. Another guy had been leaving the atticc access hatch open to let the house heat go up there for some crazy reason
damn paragraph thing quit working again

I think the same thing with the sheeting size but I didn't count the tabs-just looking at the picture I was thinking the 8' looked long for the bumps and no person could be that off with layout to cut every sheet to 6'6" It's got the repeat and the stagger.
Add your observation to my thinking I haven't seen a shingle that cheap looking in a long while. Might be that most at least try to look like a dimensional here in the affluential neighborhoods of NW Oh.

I have to agree with the other poster, that looks terrible, it looks like they didn't stagger the joints on the sheathing and didn't use enough nails, if thats gutter that I see it looks like it has no fall on it, that could be a possible future leak if you don't have one now
Yeah, looks like a 20-year-old roof on rotting OSB.
Hard to say about the drip down the siding without more info.
Whereabouts do you live??
Uh Oh
First - Stay off of the roof. Many builders will void your warranty if you get on the roof. Even if this is a means and methods problem you don't want to get into the warranty fight.
Second - It's a problem. If your builder is a stand up guy, he will be tearing into that immediately with no fuss. If he is not, document your conversations, get estimates and paper the file.
Take a pix inside the 'attic'
looks like 1/2 ply on 8 ft centers - yowsa.
Even my scrap sheds dont look that bad, it will only get worse.
Care to share the 'company' name?
I suspect that the dryer or bathroom fan duct was never hooked up to that gable end exhaust like it should have been, or that it got knocked loose by somebody.
The water is from condensation like Calvin said.
Over time, that same moisture venting into the attic instead of to the exterior would do that to the roof sheathing. It is absolutely not normal. If it is normal for that "builder" he should be driven out of the business.
Yeah, I ran into two different homes in Biloxi where the bath vent was never connected to anything.
