You should have been given the option.

Is a permit required in your town for a new roof. If yes. Get the building inspector to have a look.
I hate to say it, but I am a single woman and he thought he could slide. I am also a very observant woman and I know when something is not right. I live in Dallas aand the old boy system is alive and well. Women do not get on the roof (although I would if he had asked)

If that was true all roofs would look like that.

There are plenty of forums for legal advise. I agree with everything the members here have stated. I would guess you have no vents at the very bottom of your roof, under where the gutter would go(soffit venting) You have one very small shiny vent up at the top of the roof. The heat at the top of your roof is escaping through that shiny silver vent at the top of the roof, but being trapped at the bottom of your roof causing all the ripples. The problem being, as stated prior, not enough venting. If I was in your position have a different roofer come out and ask him to document what is happening in write and photo.

Adding vents wouldn't be too bad. I had to do this on a house where there was mold growing because moisture was trapped in the attic with no place to go or circulate.

Thank you all for your valuable input. Just re-capping, it appears that this is the fault of the roofer and that he should fix the problem. Correct?

That sounds more like a legal question. A lawyer's first question would be let me see the contract. A judge is going to want something from a reputable roofer stating what is happening or has happened with the roof. Everyone here had a chance to give statements about your roof. We are in agreement that without being there on your roof. We are only speculating.

In short, no. It doesn't show as much under thick dimensional shingles, but OSB shows under most every roof.
There is a lot of speculation about why; super thin shingles, moisture escaping at the joints, swollen edges, the newer plastic felts, (they are tarps without gromments), etc. When the light is right, it can be seen on every roof that has osb to some degree or the other.

Yeah, what "Tinner666" says!
We see what he describes all over the area.

All we use is plywood for roof sheathing.

I'll add my observations and guesses.
Each "ridge" looks to be the edges of a sheet of plywood/OSB. Using the shingles as a gage you can measure out the 4 x 8 sheets. Do we know what the sheathing is? Plywood or OSB? I am going to guess OSB as I have seen very few houses built with Plywood anymore. Next question is...What color was the last roof on the house? Was it a lighter color? Maybe architectural shingles? The reason I ask is they may have masked the problem before to the point you never noticed it. If the roof is OSB, and I suspect it is, if it got wet a couple of times during the original build the edges would have swelled up. This also could have been made worse if there was a heavy dew durring the nights that the roof was off. OSB does not like wet conditions at all.

I don't know if it is OSB or plywood. The house was built in 2000 if that helps. I live in the Dallas area. The roof was builder's grade material. The new shingles are almost identical to the original in color (Weathered Gray). They are not architectual.

From the invoice -

Tearoff
35.03 o/40.33 gb
new felt 30 lb
25 yr warranty
install osb decking
new vent jacks

that is it

I think we can assume its OSB. Looks terrible, i would be upset too. I would try to get the roofing company to fix it but i think this wont be solved by the two parties involved.

DUH!

After I posted that I realized that it was OSB not plywood. My bad. I have an attorney looking into this... maybe it will go into mediation

Just thinking out loud here... If the contractor replaced the OSB sheathing he may have gotten into a bad batch from the supplier. If the yard he got it from left it out in the weather it would have soaked up water at the edges and swelled before he even got it.
HMMMMMMM...

He did not replace the OSB (even though it was on the estimate/invoice) and therein lies the issue...
