plywood expert needed

[PDHal3]

Need a plywood expert that isn't tied to the plywood manufacturers to give rational advice and tips on plywood roof sheathing and its pitfalls, if any.

 

[JAE]

Do you have a specific question or are you looking to hire someone?

There's nothing wrong with the American Plywood Association, now called the Engineered Wood Association,

As far as "rational advice" the UBC has good info on nailing schemes for roof sheathing, as do several good books on timber engineering. Plywood is an excellent, economical roofing material and there's nothing wrong with discussing things with manufacturers. I mean, just ask to speak with their engineering department.
