Nail pops

Hello. We just bought our first home and moved in a couple of days ago. I noticed a few nails laying around on the deck. Looking on the roof looks like that is where they came from. There were approximately 12 shingles that have patch on them to cover nail pops. I have attached a picture.

In your experience are these something to worry about? If so what should I do about them? Thanks in advance.

The whole shingle should have been replaced at a minimum.
Need a picture standing back further for a better idea of the big picture.
No one mentioned this on the home inspection report?

Nail pops


Caulking a nail pop is a temporary solution to tide over the (what should be) short elapsed time between the repairs and shingle replacement.

Nail pops

Replacing the shingles is one option for a fix but if they were otherwise un-damaged the roofer may have just repaired it by pulling the old nails, putting a larger one back in, then tarring over the nail head to seal it back up. Really, it is an amateur repair job and not a best practice. He really should have pulled the shingle, pulled the nail, and either moved it a couple inches in one direction or another if it was below the shingle or replaced it with a larger one if it was securing the shingle. And if he dabbed a touch of asphalt cement on the hole in the shingle he should have sprinkled some granules from the gutter over it and let them dry on it so the patch blends and is protected from the sun.

Nail pops can happen for a bunch of different reasons. Most commonly the wood under there is shrinking and expanding with the weather, gradually working the nail loose over time. If nails were not properly hammered flush with the shingle (under driven, over driven, driven at an angle) this can increase the likelihood it will happen. Sometimes nails in the sheathing underneath the shingle will pop and cause it to tent up in the middle.

One thing I would want to know is was the last roof replacement a complete tear-off or were new shingles nailed over the old ones. If they just added a layer and did not use long enough nails this could become a bigger problem as time goes by. Even if they did a complete tear off, nails that were too short to get a good bite on the wood underneath could be causing the problem. What size are the nails you found?

Thank you all. The shingles look fine so I think I will give "pulling the old nails, putting a larger one back in, then tarring over the nail head to seal it back up" a shot.

@ eharri3 - Nails are 1-3/4". It is the original roof, about 10 years old.
@ joecaption - It was in the report. I just happened to get to the deck before they did during the walk through. They suggested monitoring and patching as necessary since the rest of everything looked fine but figured I would check with some DIYers and get a second opinion.

Movement of your property is a big player. A poorly vented attic and increase the likelyhood of this problem.
