I just got a call from a roofer who looked at my roof and prepared an estimate. Some of you may recall that I had what I called =93nail pops=94 pushing through the tabs of my 20 YO asphalt shingles.
All of the following statements are "according to him"
- There is no such thing as a "nail pop".
- Ring shank roofing nails cannot back themselves out due to contraction-expansion cycles or any other reason.
- In my entire career, I have never seen a roofing nail back itself out and I have done hundreds of roofs for all of the high-end builders in the area. They wouldn't use me if I didn=92t know my stuff.
- The reason your house has nail heads popping through the shingles is because these were "high nails" - nails that were never properly set by the contractor who installed the roof. The compressor didn't seat the nails completely and the roofer was too lazy to grab a hammer and pound them down.
- I will hammer all of your high nails down and add a second layer over the original
- I will guarantee, in writing, that the original nails will not back themselves out and damage the new roof.
So what's the deal? Can roofing nails back themselves out as I have heard from many sources or does this guy know the "real story"?
