nails through ceiling in attic
2 Attachment(s)
I have some crawl spaces in a spare bedroom and I noticed that alll through the roof there are nail protruding through. I am not 100% sure if they are whats holding the shingles down but my question for you guys is if this is normal for them to be protruding through? I have attached some pictures so you can get a better idea. Thanks a lot! Love this website.

Yes. Very normal.

Watch your head.

Normal and as intended, "On thinner decks, nails must go at least 1⁄8" (3.2 mm) through the deck."

Yep! On plywood decks, they must protrude.

It's unanimous (if asphalt shingles above)!

"R905.2.5 Fasteners. Fasteners for asphalt shingles shall be galvanized steel, stainless steel, aluminum or copper roofing nails, minimum 12 gage [0.105 inch (3 mm)] shank with a minimum 3/8-inch (10 mm) diameter head, ASTM F 1667, of a length to penetrate through the roofing materials and a minimum of 3/4 inch (19 mm) into the roof sheathing. Where the roof sheathing is less than 3/4 inch (19 mm) thick, the fasteners shall penetrate through the sheathing. Fasteners shall comply with ASTM F 1667." From:

I would store any items/electronics in a air-tight container due to the flying fiberglass fibers everywhere in your attic air space,
not even mentioning the possible moisture present...

nails through ceiling in attic
As long as you don't see them protruding through the open eaves outside your house, the nails in the attic are normal.
