A snow-storm came through with strong gusts of wind and built up slush falling off the trees hitting my roof. I took a close look at my shingle roof afterwards to see if there was any damage. Roof looked alright but there was a shingle about half way up that was sticking up because there was a 1″ roofing nail stuck underneath it. The nail was laying on its side with the head facing down the slope close to the edge of the shingle that was covering it.
This is a stupid question but its driving me nuts: how could it get there? It could have been there since the shingles were installed but it was pretty noticeable and I haven’t seen it before so I don’t think so. Could it have been trapped farther back under the shingles and the strong wind gusts of the storm agitating the shingles moved it down slope somehow? Wind lifting up shingles and yanking out a nail that was actually holding something down? The nail itself looks pretty clean, but I can’t tell if it’s been driven or not for sure.

It is not unusual to find extra roofing nails.
the roof on my house is 16 years old, and I have to blow or spray leaves and sticks off the roof twice a year.
last time I did so, guess what I found?
I've even found bullets buried in shingles, one in "the ghetto", one in suburbia, presumably from people firing in the air at New Year's.
My guess would be this nail has been there all along, just inconspicuous. Careful roofers sweep when they're done, but even the most diligent can miss a stray nail.
If you have access to the underside of the roof check the area for a nail hole that doesn't have a nail......it may be it. I would think that a nail laying on its side would be be seen when the roof was being shingled.

Nah, a nail on its side could hide in there for a long time if that head is in a slit or gap between shingles. A good storm could then get the shingle loose just enough to let the nail roll down a bit and there we are.
