What causes nail pops in a roof?

[Andy Jarchow]

Is it just because the wrong nails were used or the nails are not long enough?

If you just reset them won’t they pop back up again?

How do you fix the problem?

Do you recommend a roofer if there are just a few nail pops lifting the shingles above even if they haven’t caused a hole yet?

Thank you? :)

Many, many reasons for nail pops.

As far as recommending a roofer...is that the only thing you found?

I would use in this particular case...qualified individual. I just don't want them getting on the roof, sliding off and then saying that they were just following my instructions.

With expansion and contraction of the roofing underlayment throughout the seasons, roofing nails will often extrude.
Resetting and tarring the head to hold in place will usually work. Typically it will be a nail that was not set real well at install.
Annual inspection and maintenance to roof will do.

The roof was is good condition except for 8 nail pops. I just told him they should be reset. I didn't know about the tar thing. :o I didn't recommend a roofer. Maybe I should have it was about a 10/12 or 12/12 pitch:eek:

Thank you all

A couple of pics from last week. Just one nail on the whole roof, could very well be in a seam between two sheets of OSB.

I have to agree in recommending a professional roofing contractor make needed repairs in my reporting. Just good liability to always recommend a professional contractor.

Hey

Here is a good roof for you. I was doing my do diligence today checking for nails and how many and what type. With thumb and fore finger I slightly lifted the edge corner of several shingles around the roof. No pressure in the slightest and as it was only a quarter inch off the roof in the beginning the entire run in many areas lifted. A slight more pressure and not ripping shingles at all and the lift kept going.

The pic below can see the thumb and forefinger barely lifting and the whole run started to lift I have about 8 more pics of different areas.

Roofing company had to make some budget cuts so they decided not to use so many nails. :rolleyes: Looks like a pattern did they only put two nails in each and only on the right side? :eek:
