Roof question

[Randy D. Stufflebeem]

Hump in roof. I inspected this home April 3rd. This hump has appeared that was not there at the time of inspection. My client or the agent does not remember the hump either. It is clearly seen now from the street. The home is 1 hour away and I really am finding it hard to find the time to go check it out. Client wants to know what it is. Can any of you guru's help me on this and possibly save me a 2 hour round trip? It almost looks as if nails have pulled up?
Thanks for any advice,
Randy

Warped sheathing?

Richard,
That was one of the things I thought about. It almost looks like a small bubble which makes me think it is something other than warped sheathing. But who knows?
Thank you

Can they get a pic inside the attic? - that would help.

Unfortunately, the buyer has not closed on the home and that was the only photo he could get. Can you blow it up to get a closer look? I will add we have had two huge storms since the inspection with high winds and pounding rain if that helps at all.
Thanks

I cant seem to blow the pic up enought to adequately see what I need, so here goes........

High winds, pounding rain........water could have got under the shingles and combined with the wind would/could pull sheathing loose and cause bubbles in the felt paper. Loose sheathing would cause the hump shown, especially wet sheathing that dried too fast.

Randy,
Have you been hitting the Bud Light's again??????

[Barry Adair]

This could be attributed to a broken or slipped purlin support/strut; purlin sags and the support/strut bulges the deck causing the hump. I have this on a rent house I've not yet attended to. Someone will have to enter attic to verify whatever this is.

don't know about yours, but this was a sheathing pop caused by condensaton in the attic insulaton were the vapor retarder had been damaged:

I guess not near like I should be!

[Randy D. Stufflebeem]

Dug up a couple attic shots from the inspection! Not very good ones!

[Randy D. Stufflebeem]

And here is a couple shots of the roof at the time of inspection

The Home and the hump is near the right side





This is the same area at the time of inspection.

I am also starting to wonder if I can be held responsible in any way. Don't get me wrong because there has been no mention of that but one can never be to careful. What say you?

[Barry Adair]

Your attic shots ruled out my purlin therory
I don't see H-clips between sheathing and what appears to be a number of missed deck nails would lead one to believe this could be an improperly secured deck expansion/spacing issue

It looks newer.
How old is that roof?
My first thought was sheating also, if you want as many opinions as you can get.
