Warped board on roof?

Noticed this bad lift in my roof about 8 months after buying my house. It happend after a bad rain storm we had. I went up in the attic to inspect the problem and found a board had pulled up a good 2-3". I took some pictures of the problem that I will give links to. Whats wierd is that the board has almost settled back down into plae and hasnt lifted up since. Should I cut the nails off and try to strap this thing into place maybe using some short screws and an elbow bracket? I can see some water stains on the wood but ever time it rains I cannot find any water. Thanks for any input on this. I need to try to make this roof last me another year or two!

wow that is pretty odd. If it will settle back with the old nails not holding it up I would just leave them. Problem with trying to secure it from inside that I see is it would be hard not to shoot nails/screws through the roof and you don't want that. I would probably try to tack it back from the top. Maybe have one person stand on it to hold it down if you need to and have someone lift the shingles carefully where the sheathing joint is and renail it. Best I can think of I don't recall ever seeing that happen before.

old nails are holding it up.. I was going ot use 1/2" screws and some metal L-bracket.. probably 3 or 4 of those on it when I get it pulled back into place. I have a roofer coming next week but I wonder if I can do it my self.

How old is the house?

Are those nails or staples?

hrmmmm

I would get some liquid nails on the rafter top plus trying to secure it. You really should nail that down properly from the top.


A quick suggestion, if you ever reroof, get them to renail all the plywood.

Copyright,

Do you live in Florida (saw the pine trees in your picture) or some other place hit by a hurricane? I bet the board pulled up in a high wind and the home owner knocked it back down before selling the house. Looks like staples to me, which is now a no no in Florida.

The L bracket and Liquid nails looks like the way to go for now. I agree with nailing all the plywood when you get the new roof.

Just a DIY'er like yourself, so listen to the pros on this site.

Good luck.

did yoiu get any kind of home warranty ? check into that

(i doubt it was hurricane damge the wind would have taken the shingles off before popping the board)

Im in Texas and yes there are pine trees all around me unfortunately. What worries me is the water stains on the underside of the board even tho ive never seen it leak. Im pretty sure I can just L-bracket the board into place and use some liquid nail to help secure it. Not sure what a roofer would do. Probably tell me to replace the roof. Its not in to good of shape.

I am wondering if the deck board is not centered over the rafter and the nails/staples cannot get enough of a bite to hold it down flat. My inclination is to scab a board (2 x 4 or 2 x 6) along the rafter flush with the top edge of the rafter. Remove enough shingles to allow you to get screws through the deck into the scabbed nailer then re-install the shingles. You will never be able to pull this warped decking back into position with screws from the inside. You will need the head of screws installed from the exterior to pull the plywood back in place.
