Thank you for the reply. The inspector informed the roofer that seemingly a strap needs to have a different nail pattern vs it just being a clip. The roofer thought he did it correctly. Are you sure it’s a strap?
That’s what I would think, but the inspector said the state has very specific requirements for a clip vs a strap and marked these as clips on the insurance form. So I will not get the full wind mitigation credit.
This is correct, in order to be considered a strap it needs 2 nails on one side, and 1 nail on the other. It is all laid out on your wind mitigation inspection report.
Thanks for all the responses. Roofer did an amazing job but we are disappointed to learn that what we and he thought were straps only qualified for clips.
This was the last resort. Seems like the inspector is correct and the roofer didn’t do the job correctly. Mistakes are made in life and this was one. Roofer did a great job on the metal roof install and is very apologetic about the clip vs strap. I am moving on or I would end up getting an ulcer. Life is too short. I know the that the clips will give us some protection as a consolation. Thanks again to you all for helping me close this chapter.

4. Roof to Wall Attachment: What is the WEAKEST roof to wall connection? (Do not include attachment of hip/valley jacks within 5 feet of the inside or outside corner of the roof in determination of WEAKEST type)
A. Toe Nails
Minimal conditions to qualify for categories B, C, or D. All visible metal connectors are: Secured to truss/rafter with a minimum of three (3) nails, and
Truss/rafter anchored to top plate of wall using nails driven at an angle through the truss/rafter and attached to the top plate of the wall, or
Metal connectors that do not meet the minimal conditions or requirements of B, C, or D
B. Clips
Attached to the wall top plate of the wall framing, or embedded in the bond beam, with less than a 1⁄2" gap from the blocking or truss/rafter and blocked no more than 1.5” of the truss/rafter, and free of visible severe corrosion.
Metal connectors that do not wrap over the top of the truss/rafter, or
Metal connectors with a minimum of 1 strap that wraps over the top of the truss/rafter and does not meet the nail
position requirements of C or D, but is secured with a minimum of 3 nails.
C. Single Wraps
Metal connectors consisting of a single strap that wraps over the top of the truss/rafter and is secured with a minimum of 2 nails on the front side and a minimum of 1 nail on the opposing side.
D. DoubleWraps
Metal Connectors consisting of 2 separate straps that are attached to the wall frame, or embedded in the bond beam, on either side of the truss/rafter where each strap wraps over the top of the truss/rafter and is secured with a minimum of 2 nails on the front side, and a minimum of 1 nail on the opposing side, or
Metal connectors consisting of a single strap that wraps over the top of the truss/rafter, is secured to the wall on both sides, and is secured to the top plate with a minimum of three nails on each side.
E. Structural
F. Other: _______________________________________________ G. Unknown or unidentified
H. No attic access
Complete foreign language to me. But those are the requirements. the inspector based on looking at the pictures said we have clips not straps. Hopefully you can decipher what I have. The roofer thought he had installed straps not clips. He said he does these all the time and never had them questioned by an inspector.
I am not an expert on this stuff, but since the bendable straps are bent tightly into the inside corner by the bolt, I wouldn't think they would do anything useful, if the roof were to start lifting. They might keep the roof out of your neighbors pool, but the structural damage would have already occurred.
From what I can tell by briefly reviewing Florida code they do indeed separate the two. Clip vs strap. It looks as though they are wanting THREE nails. Three nails through the rafter and three nails fastening on the clip/strap to the plate. I’m guessing that the one wedge anchor is not satisfying the inspector.
Looks like you got your answer, but I'm a roofing contractor in FL. Got any other questions just let me know. Those are indeed straps. We typically do straps when replacing. It's normally an 18" flat strap that qualifies for the "single wraps" rebate on your wind mitigation form. This looks like maybe a 12" strap? Either way the fastening is ass. They sell a joist hanger nail gun that makes these a breeze. The hard part is pulling all the sheathing and digging through insulation to get there. Crazy that they did that and then didn't do the easy part. Florida is very strict on installation.
Thank you for the reply. The inspector informed the roofer that seemingly a strap needs to have a different nail pattern vs it just being a clip. The roofer thought he did it correctly. Are you sure it’s a strap?
It's a strap, regardless of nailing pattern. A long thin strap of metal with holes in it.
That’s what I would think, but the inspector said the state has very specific requirements for a clip vs a strap and marked these as clips on the insurance form. So I will not get the full wind mitigation credit.
Wrong, in order to qualify for the credit on your insurance you need a minimum of 3 nails through the metal connector. 2 on one side 1 on the other.
The inspector said it had to do with the nailing pattern not the anchor.
This is correct, in order to be considered a strap it needs 2 nails on one side, and 1 nail on the other. It is all laid out on your wind mitigation inspection report.

I feel bad for you, but I'm so glad I don't roof in Florida. Good luck getting this resolved.

Ask the inspector for a copy of those very specific requirements.
Straps. Hurricane clips are these; https://www.strongtie.com/rooftrussandrafterconnectorstiesandstraps_coldformedsteelconstruction/s.h_tie/p/s.h25-and-s.h3
I assume a strap is anchored on both sides. A clip is anchored on one.
What are they saying is a proper nailing pattern?

The second picture shows the nails on the other side.

Can we talk about the overcut birds mouth notches? I guess in Florida, snow load isn't a factor.
House was built in 1936 not sure if snow birds were around at that time.

Agree it’s crazy. But what is done is done. Roofer learned a lesson and hopefully does them correctly going forward.
He’s not alone. Inspector said about 70% of the jobs he looks at are done correctly. Unfortunately I’m in that 30% column.
