Roof Deck Miami-Dade
Roof Deck Miami-Dade
(OP)
Hello,
Not sure how many on this forum are located in S. Florida, but I was contacted by a contractor today and told that they could not find an Notice of Acceptance (NOA) for the 3" Type N roof deck that we call out in our drawings. The county is saying that the maximum roof span allowed per the NOA is 6'-0". This project has already been approved for permit by the way. After looking at these NOA's these are mostly referring to roofing finish materials and their attachment to Type B decking. I get that type B decking shouldn't span farther than 6ft. on a roof in Florida but as N deck is specifically made for larger spans, I'm not sure of this issue. They're responding as if the county hasn't approved a material that by design can take the required loads. Has anyone else ran into this issue? Any further information or methods of resolution would be appreciated.
Thanks.

You can have an NOA and it will suffice. If you don't have an NOA then you can have a Florida Product Approval. Either is valid, anywhere in the state, even HVHZ, as long as the approval meets HVHZ requirements. Obviously, everything with a Miami-Dade NOA must meet that; however, for Florida Product Approval, it might or might not meet HVHZ requirements.
Interestingly enough, there is no real requirement that any product have Florida Product Approval; however, most building officials do require some evidence of an approval (NOA or FPA). Further, the standard of care would dictate using a product with stated approval.
You can get a local product approval based on a rational engineering analysis. Check with Miami-Dade for their requirements. I have done local product approvals in North Florida and it all depends on the local building official as to the requirements.
Welcome to Florida!
