To me it looks like it needs to be a single ply roof. No where near enough slope to shingle that.

I'm guessing he used tar paper as his underlayment.

Grace Ice & Water Sheild under the tabbed shingles would have helped a lot.

Yes im sure it would. He did say he put some down but i belive that was in the slope tie in. Doing the whole thing would help. Still for me its to low of a slope. If he doesnt want the looks of a epdm or tpo roof, one could use a SA Mod bit they come in somewhat matching colors of the shingles. They have it in torch down too. Also some TPO makes have a shingle inprint on them. Couple of ideas.

Too low a slope and a dip at the tie-in. Rip it off, get a nailable base, 1-2 inner plies and a brown granuls SDS Cap sheet system on there, all the way to the ridge.
Make sure the tie-in is done correctly; Run the sheathing up to the tie-in, take the first existing board fromt the rafters. Finish sheathing into the existing rafters, re-cut the board that was removed to fit and re-install it.
I'll look for a pic while you read this.

Improper installation for sure.
Cracked shingles
Low spot at transition line
No wall flashing( that I can see)

If you want my advice, I would do as was mentioned earlier in this thread.Get a roofing contractor in there. He will be able to place a modified roof on it and your worries will be over.

I am not sure as to your relationship to the builder of this project, perhaps he should be excluded from any future work on your house.

Great pictures! So, basically, he should have ripped off the lower part and tied it in, rather than just laying the new one on top....? I am sure there is more to it than that, but that is the general idea?

Just at the transition. The old decking is cut back a few inches to allow the new decking to sit flush with the elevation of the old. In tinner666's pictures the addition is done in a similar fashion to yours. Notice in his pictures the new rafters are nailed on top of the old roofing and decking.

It could be framed properly either way. The leak issue is not in the framing. The roof slope appears too low for 3 tab shingles (and maybe for dimensionals with ice and water shield under them). The new portion of the roof needs some type of membrane on it.

Both slopes look to low for shingles of any type. He couldnt have tied in the new shingles look how far down the old shingles go, right to the breaking point of the two slopes. I doubt you have much warranty so you might be on your own. Get a couple of low slope roofers to look at it. The dip could be feathered out with a tapered edge strip that will make it smooth. The builder should have decked this right. Put a single ply membrane or a 2 ply with a SBS cap sheet. You will be much happier and leak free if done right.
