Attic Sheathing

I was wondering if anyone has any clue why the 2x4s are adhered to the ridge area and also I can see the evidence of previous water but was wondering why the difference in the sheathing of osb and than plywood.

Not my expertise, but on pic #3 what’s the purpose of that type of “vent”?

Roof repairs most likely reason for OSB, those roofing nails are way too long and judging from the caulk on the 2x4s I’d say to keep the wasps out ,I’ve seen the vents full of spray foam🙈 . Looks like they added a turbine vent …all speculation of course

I’ve seen this type of handyman repair from underneath the roof before. They tend to associated with REO/foreclosures in our area where the Craigslist “contractors” use whatever they have on the truck to patch/cover up damaged OSB sheathing from the attic space. These are temporary repairs at best, and are usually accompanied by off colored shingles directly above/near the patch. If you walk the roof, be careful because these tend to fail suddenly and badly…

Inspections shouldn’t be that difficult… I couldn’t stand behind such sloppy work. Sloppy work to me indicates lack of knowledge and skill. I would definitely have it looked at to shift any liability to an “expert” so it doesn’t come back to bite. It may even require invasive inspection to really figure out what the heck is going on.

Since I’m still in the training/education part of home inspector training would you recommend “further evaluation by a qualified roofing contractor”, given the evidence in the pictures? I see signs of water damage, the caulked/glued 2x4s are a red flag, and in the 2nd picture, I see a split/chipped piece of sheathing.

The one on the right is a plumbing vent and the one on the lower left looks like a cobbled “B” vent, IMO.

I hope all is well down south, Marc. :smiley:

All AOK down this way… except for the hurricane coming my way.
Gonna get TONS of rain/water but hopefully it looks like the direct hit will be hundreds of miles north of me.
If I’m very lucky the winds will “only” be 50-60 mph. :open_mouth:

Hang on!..:flushed: :sunglasses:

Stay safe Marc!

When the plywood is split that way I check to see what size it is - I have seen 1/4" plywood used for the sheathing!!! Vent openings are a good place to measure. OSB could have been where it was damaged enough to be replaced. Here in New Mexico house roofs may get a lot of foot traffic due to seasonal evaporative cooler servicing. The thin ply does not hold up to overweight people walking on it. There is also more deflection, so more prone to leaks as well.

Did an inspection today & the buyer wants to pay me to go back AFTER the storm to check for roof leaks, water intrusion, etc.

I am NOT thrilled about this whole thing. Now I may get stronger winds & the rain… … … - it’s crazy when it looks like a monster wall of water just keeps coming & coming & coming.
I may get up to a foot in rain-YUK!

Hang in there, Marc. I’ll pray for you and those affected by the storm.
