The mysterious Hole in my Roof
steve1431

Hi all , i am looking forward to hearing from all the roof experts that view this forum. I was going through some old home improvement construction pictures the other day and came across some pictures i took off one of my "mysterious" nail problems i had with my roof. As i recall it was a total of three in a relatively short period. It was probably over a two month period during the spring of 2013. It was two roofing nails and one roofing board nail. My house was built in the 50's and has 1 bye's running under the shingles. I discovered the roofing nail holes thanks to the rain leaving a water spot on the ceiling in the kitchen. The other was a drip in the basement, It was lined up with a wall and ran all the way down to the basement where it left a puddle on the floor. The third and last was the most puzzling. I discovered this one while i was on a ladder cleaning out the gutters. See the following pictures.

Has anyone seen this happen before ? or have any idea how the one in the picture occurs?

Thanks Steve

The pictures give a limited view, but from the pictures I notice that: 1. the one rusty nail is not a roofing nail, and 2. this nail was driven next to where a nail is missing.

What I don't know is what's under the shingles.

One quick fix is to pull this nail out and plug the holes with some roofing cement, then drive a new nail. While you are up on the roof, inspect and seal any other holes there are and around vents, chimney.

If this roof is over 20 years, consider replacing it. Don't wait for November to do that - prices will go up for winter and you will have a hard time finding a competent roofer for the job.

Just a guess but they may have been nails for roofing jacks when the roofing was installed.

yes that is a strong possibility. roof jack or put there to hold a small compressor from vibrating down the roof.

Replacing the shingles damaged and all is good.

Sorry it took so long to acknowledge, I was having problems logging in.
The nail was a small framing nail "miss" that was meant to hold a roofing board. My roof is not plywood, it has long 1 by's running under the shingles. I think it was a miss because the nail hole was just off the edge of a rafter. I did promptly pull the nail and seal the hole.
My question was: Can a nail, like the one in the photo, back itself out of a roofing board, or does it need help from something else, maybe snow/ice freezing and melting?

yes but not that far. That looks more like a nail that was installed to keep a small compressor from vibrating off the roof or to hold materials in place, maybe for a roof jack or to keep a air hose from sliding down the roof. maybe it was windy and they nailed a T-shirt from blowing away. Who knows??

Nails do pop, especially on old, dry planks. I doubt that a popping nail can push through shingles and 30 lb tar paper by itself, I think the nail in the photo was applied from the outside.

Your fix is good, for now. Go up and check it periodically, since under the sun, tar shrinks.

OK, that's what i was thinking. I appreciate the quick response from everyone.
I'll go up before winter sets in to check it.
