Roof Leak - is this reasonable?

During a recent heavy rain we noticed a leak on our ceiling in the bathroom. I looked out on the roof over the bathroom and from my non-knowledge eye nothing seemed wrong - the shingles look fine and not worn.

However, there is a vent pipe above where it appears we have the leak. So I suspected that is likely what the culprit is.

So I called a roofing company that was recommended and from what I can see has 4.9 out of 5 stars - one person gave 1 star because of some unrelated item in regard to the name of the company that never used them and also reading the reviews they seem a reputable company.

I talked with the guy and he says he charges $150 to come out and diagnose - it is non-refundable and not netted against the price of any repairs. He thought it likely a two person job and the cost per hour in that situation would be $220 hour and they bill on the quarter of the hour. Of course any parts/pieces would be whatever they would cost.

Not having to use a roofer before - do these costs seem reasonable? I know that them just coming out costs them time so I can understand not wanting to come out determine the issue and if it ends up being something simple - you just do it yourself. I just want to make sure the costs are reasonable.

I will likely speak to some others - I have gotten other recommendations but these guys seemed the most responsive and had the best things said about them.
