Buckled Shingles

I noticed this at 10am this morning. I live 60 miles from Canada so summer temps are 70s/80sF. This section of roof gets sun most of the day.

Is this a problem? If so, what is the fix?

Thanks.

It's relatively new, 4 years and the shingles are GAF Timberline HD.

Have you been up on the roof to inspect more closely? look at the bottom side in the attic?

I'm a senior and don't get on rooves anymore. I haven't been in the attic yet either. I was hoping someone could tell me what the likely causes and fixes are. If this is something to worry about there are only a few things it could be and a few fixes.

If the bump seems to be roughly 4ft long, it's likely that the end of a sheet of sheathing didnt get nailed. If that is the case, you would be able to see this from inside the attic.

Per the photo it's about 2'. If it is sheathing that wasn't nailed properly what is the fix?

Take up shingles, cut underlayment, nail it down (6" on center), patch underlayment, patch shingles.

I suppose some doofus might nail right through the shingles then caulk the nail heads. Guess it depends if you want a cheap fix or not.

What about sistering a 2x2 to rafter of the loose sheathing then drawing the plywood down with screws? Maybe a dozen or so over the two foot area. Could have someone standing on roof over the warped plywood to press it down. Wouldn’t get it perfect but maybe enough to minimize the bump. Obviously watching to not go through the plywood from below? Spread liquid nails into the gap from beneath beforehand.

Removing shingles and doing from top is better. I am just one who hates messing with a newly shingled roof in the middle of it. If this can be done well without visible patch look it would be the way to go.

Thanks guys. At least we know it's the underlayment. Since the roof is only four years old and under warranty, is this the type of thing the roofing contractor should cover?

I would wonder why he didn’t notice the loose sheathing during the rip off and such. Unless he pulled out the nails that held it down to the rafters. But that would be unlikely. I do wonder why the last roof didn’t buckle.

Since the home is only 4 years old, this is the original roof. Should the roofing contractor cover the repair since it was an installation error?

The framer is responsible for the roof sheathing. Not the roofer.

You might contact the builder and see what he says. Typically they only warrant a new house for 1 yr but a few builders will go the extra mile.

Thanks all, I'll pursue the framer.
