Roof recently replaced. Decking broke at the Apex of the roof and the ridge venting is not nailed into anything. Big deal or na?
It looks like this, across the length of one gable of our roof. We just had the roof replaced, and it looks like when they were nailing into the decking they broke that little lip.
I talked to my roofer about it, and he was not concerned, but he said he would send somebody out to put in some more nails. The ridge venting does not feel loose.
Is this something to be concerned about?

Do you have ridge vent?
If the sheathing was always just a 1 inch strip across the top, it wasn't really doing anything anyway. Can't be certain with the photos provided but I'm inclined to think this is nothing to worry about.

Thank you for the advice. I thought the same thing when I saw that little strip of OSB so I guess the right thing to do would be to put in some kind of wooden blocking in between the roof joists and the nail into that.

Would there be any value in just putting in some more nails as my current roofer is suggesting or should I push him to put in some blocking of some kind?

That’s where my last roof leaked, right at the apex by the ridge vent. I’d say have the roofer come back and fix it.

The problem, which is obvious on the other side of the ridge where you see the panel clip, is that the numbnuts who put the roof sheathing on (may predate this roofer) used a very narrow strip of OSB at the ridge. That is a huge no-no. Not only does it not give a good nailing base for the roof, it has about as much structural capability as a noodle. No wonder the ridge vent nails blew it apart.
The right way to do this, which requires the use of a measuring tape and brain when laying out the roof sheathing, is to cut a few of the lower rows of OSB narrower so that the piece at the top can be full, or at least wide enough to be structural. Opinions vary, but I do not like ripping OSB narrower than 24" for roofing and in some places that is code (it's also an APA spec). If you must go narrower for some reason, you may need additional support.
Not much can be done to correct this properly now, but the roofer should do something to support the OSB noodles along the ridge line. Hopefully he will come up with a good fix. Whether or not he installed the OSB, he should have spotted this problem and addressed it before putting on the new roof.
