The latest “nails through the decking” had me wondering…
We see older houses with plank type decking & often have to do repairs to slats because of fractures as a result of the sap drying out & knots, however this isn’t really a concern with ‘true’ ply or OSB.
Since ply or OSB sheeting hasn’t really been the standard for more than about 30 years @ the most, my question is this:
Assuming that a roof deck has been fully stripped of felt on EVERY re-roofing, which we all know is very unlikely unless it’s required by code & completely inspected for this, @ What point would you consider it to have too many nails & the integrity of the deck to not properly hold any new nails?
Also, how many of y’all pull all & I do mean ALL of the old roofing nails & roofing staples? I know that my crew prefers to bang 'em flat whereas I’m more of a “pull what won’t require destroying the deck” kinda guy.
I guess that it’s going to be an issue for roofers in 100 years as to whether or not the plywood has been overshot with nails & not in our lifetimes (unless medical science has found a way to keep us alive for a lot longer than we already are).
