I bought a new house in July and they had a new roof put on before my closing. I was in the attic the other day and saw chunks of the plywood missing near the peak in at least 10 spots. You can see the protective sheeting sagging through some of the spots. It does not appear to be leaking but I wanted to make sure it is normal. I assume they did it for venting, but seems poor workmanship. I would appreciate any advice. Thanks and happy holidays! Pictures are attached...

It's not plywood, it's, OSB. It's low end crap builders use when they don't want to spend money for plywood. You would need to remove the exterior coverings to replace it.

Nothing wrong with osb. Looks like they were a bit go aggressive removing the wood from the ridge vent slot. You could support it from underneath if you wanted to, depending how big or small the hole is, I may not bother.

My first impression was a squirrel or other critter trying to get out. Are there a bunch of chips on the insulation/floor directly below?

Probably not, but check the chips.

Thanks for the fast responses. I am happy to hear that it may be OK and not need to be replaced. The roofer is coming by tomorrow and I wanted to have some knowledge before he began his argument. I thought about the animal aspect but don't see why it would only chew at the very peak of the roof and no where else. I do not see any droppings, but there is some dust on the floor near a few of the holes but also large chunks of OSB. If the roofer wont repair, and it doesn't leak, would it be OK to monitor. I would support from the inside but its a good 15 feet up and would be very hard to get to.

100% agreement on all points :vs_karate:

Typical professional where a claw hammer is used to make a vent hole.

Theres no weight there so no structural issues. Very bad craftsmanship, but its nothing to worry about. (from the pictures only)

Good day

Not sure what the issue is. Typically if there is a ridge vent installed you will cut back two inches of sheathing on each side of time ridge. So no matter how much the framer hacked up the edges of the osb, as long as it is within two inches it is good. Ron

If all 10 spots are similar in location on the sheets, they may have been damaged while still in a pile (stacked) on the ground/truck from a fork-lift or other. IF just a few holes, I used to make a much smaller hole near the peak to attach our safety rope to, required by Federal law here. A steel 3/8" cable wraps around the truss member to give a temporary anchor while sheathing the roof. A permanent one is installed later, for future use that mounts ON the sheathing/truss, rather than around the truss. This would explain the 16d nail next to the truss... I don't see a ridge vent cut-in or a turtle vent there so those wouldn't pertain. You should be fine.

Thanks everyone for the helpful and knowledgeable insights. The roofer came by and was as curious as I why it was that way. He showed me that the OSB used in those areas was the original. He is going to come and support the gaps that are larger than 2 inches from below. Not sure if that will do anything, but may hide the defect from a buyer when I eventually sell since it is not in fact detrimental to the roof.

That is not a defect, just the roofers got a little over aggressive while tearing off the old roof. Just keep the bill and any pictures, to show that it was repaired.

I highly doubt that any buyer is going even notice that, unless they get a Home Inspector that is trying to sell them a inspection on opinionated statements.

By the time you probably move. You will most likely have other things to tend to inside or outside. Along with the slight chance that a storm could end up buying you a new roof.

Might look to see if there are more (in picture) than the two ink stamps for rating/span/manufacturer stamped on every sheet like normal. The ink is usually on the waxed side they use in gluing the product, should all be facing attic- not for walking on, lol. OSB REQUIRES a gap between sheets on all edges (1/8") especially long horizontal edge for expansion/contraction, ask him if not there. IF 24" on center it also requires ply clips if 7/16", read the span rating stamp.
