Depends largely on the area, and sometimes the nature of the shingle. Around here most roofers basket weave because it's faster (and a little cheaper) and it works fine if they've done it right. If they don't do it right you will get leaking at the valley. One benefit of valley flashing is that you can see it installed, whereas it's a little trickier to pick out incorrect weaving. 

 Hmmm, that's interesting, thanks for your input! I'm learning a lot about roofing here. I've never noticed these things before but now I'll be looking at everyone's roof!

@Claire GD - yup! I learned something new too. Wonder why they used tan vs black.

@Claire GD - I’m not a roofer, but that doesn’t look right to me.

You're all good.  Roofer used valley tin. Other details that are sometimes used in a valley are a weave pattern or California Cut.  I personally like the California Cut, but this detail is just fine

@Claire GD, everything looks in order. In this case the roofer used valley flashing rather than weave the shingles across the valley. If executed properly (and as far as I can tell it was), it’s the better way to do it.
