Hi IslandRoofing: In answer to your question: Since the nailing pattern of the plywood was non-standard, I spoke with several roofers and contractors. I was not able to achieve a consensus. The reactions were from not worrying about it to anger that the roofer did such a sloppy job and that I should demand that they re-roof. I thought that I would reach out to this community in order to get more clarity on my options. I don’t mean to be disrespectful, but am merely trying to become more educated. Basically, I was sold a 25-50 year roof and am not comfortable with this aspect of the job.
Those roofers who said I had a problem advised me that a house “breathes” and with the expansion and contraction, those nails could work their way up over time. The 8 penny nails are very smooth due to the coating that allows them to operate effectively in the nail gun.
The reason I am more worried about the 8 penny vs the roofing nails: the roofing nails, are hot dipped galvanized and should have more bite.
I want to thank you again for bearing with me as I further my roofing education.
