I am new to the forum and I realize this is an older post. Do my eyes deceive me or does it appear as though the low volume roof is ran over the high volume roof in the photo?
I am under the impression that the low volume roof should run under the high volume by a t least 12"

Welcome Glen....and you are correct.

Apparently roofers like cut valleys.

Valley Techniques

Cut valley is easier and faster than a woven one. Time is money, they say.

Metal valleys are better if we are comparing and install is quicker but roofer has to fork out the extra $ for the metal valley. Laminated shingles also have a habit of failing when you bend them into the valley.

Mathew, I recently added this to my reports.

It appears that the roof valley is improperly installed. This may lead to roof leaks and water penetration into building components. A qualified roofing contractor should evaluate and repair/replace as necessary. View the video at following link for proper installation of roof valleys: Video Library - How to do Valleys
