If the strap has 2 nails at my roof trusses, what credit do I get on my wind mitigation inspection?
Saturday, October 3, 2020
The Florida wind mitigation form (OIR-B1-1802) requires three nails securing the metal connector to the roof truss or rafter to qualify for a “Roof to Wall Attachment” discount. If the strap has only two nails then it must be listed as equivalent to Toe Nails, which receives no discount.
Here’s an excerpt below from page 2 of the form, with an example of what happens when there are only two nails. One of the two “Minimal conditions to qualify for categories B, C, or D”—which are categories of connectors that get a discount—is that there must be three nails at each metal connector. If both of the minimal conditions boxes cannot be checked, then it reverts to Toe Nails, based on “metal connectors that do not meet the minimal conditions of B,C, or D."
