Exclamation Roof repair concerns

Hi,

I was going to repair my roof where there's a leak in a valley myself but decided I'll get a roofer since I can't do everything myself. Despite all the research I did, it turns out that I still had losers doing the work. I had to stay on the roof for 4 hours making them do better on some things.

There is a double roof. The 1967 original asphalt shingles and maybe a 22ish-year-old GAF asphalt shingle outer roof. The 1967 roof crumbles easily when touched w/a prybar.

After a bunch of debate, I agreed that they would only put ice/water shield down on the plywood and then the outer shingles over it. They argued two layers would raise the new shingles too much. In the valley, they first put aluminum flashing, then the ice/water shield. If I had done it, I would have put a break on the aluminum so it would be sharp in the corner - they didn't.

The valley shingles were laid on the first side, bridging over to the second side, then the second laid over the first and the second side cut down the center of the valley.

Now that I'm stuck with the repair, should it have had the two layers of shingles or is this OK?

Where the 2nd layer of shingles was cut in the valley, should that edge just lay over the first layer of shingles or should that be sealed with something like silicon or roof tar?

Thanks guys.

Speaking as a contractor, there is not much worse than having a homeowner who knows next to nothing standing over your shoulder telling you how they think it should be done and questioning your every move.

Regarding the repair, it sounds like they shingled it correctly. Truthfully, the whole roof should be torn off and replaced. No way youd get me to patch a roof that still has 50 year old shingles on it.

@XSleeper - Aside from the fact that everyone that quoted the job said the roof is good, only do the repair, I NEVER intended to be the overseeing workers, but unlike what I was told, the foreman didn't show up and left the two scam artists to pull a fast job. In fact, they started pulling shingles off the wrong valley and would have ripped up a perfectly good roof if I left them to themselves. Since you seem to know so well what went on w/o being there--like them trying to tell me the broken rotted plywood sheathing was fine and them wanting to nail shingles to bare plywood, are you saying you condone scamming people?

To anyone else: I've gotten very good advice and answers to my questions here for years. Hopefully, someone is less interested in criticizing and more interested in providing useful answers to my questions. Thank you.

Oh my gosh. You sure are taking things the wrong way.

valley shingles were laid on the first side, bridging over to the second side, then the second laid over the first and the second side cut down the center of the valley.

Now that I'm stuck with the repair, should it have had the two layers of shingles or is this OK?

Where the 2nd layer of shingles was cut in the valley, should that edge just lay over the first layer of shingles or should that be sealed with something like silicon or roof tar?
Read the instructions on any package of shingles... yes, that is one acceptable way to do a valley, provided they ran the shingles far enough with enough overlap. And no you should not need any caulk or tar.

Have a nice day friend.
