I’ve got a question for you smart folks… Sorry if this has been addressed elsewhere already, I’ve been looking through the posts for a bit now with no luck.
Do staples qualify for question #3 Roof Deck Attachment option C on the Florida Uniform Mitigation Verification Inspection Form OIR-B1-1802 (Rev. 01/12) Adopted by Rule 69O-170.0155?
As I understand it they do not. It seems to me that anything but an 8d nails (smooth/screw/ring shank) lands on option A, but I have recently been informed by a very experienced & knowledgeable inspector (that I respect very much) that I was incorrect. He stated the staples still qualify in dimensional lumber because of the superior strength/friction(??) of the dimensional lumber over OSB or plywood. So under the “-OR - Any system of…” line.
But I have found nothing to prove that a min of 2 staples per board provides the same uplift resistance as the 8d nails. But I have found staples installed on many newer roofs (the one I inspected yesterday was reroofed with county permit/inspection in 2007) with dimensional lumber which along with his new comment, has me questioning my thought processes.
Thanks in advance for your assistance
