Wind Mitigation Scenario # 16 (I think)

All of the roof to exterior wall connections have straps. These trusses are resting on top of an interior wall with toe nails. For question 4, should we mark A or B?

The last picture is the front of the home for a reference point, so you can see it is not a separate roof system.

Only the exterior wall fasteners count for the wind mit.

I have also assumed that in the past. But the reason why I am asking this question is because this was a 2x removed re-inspection. Originally the wind mit was marked as clips/straps. The 2nd one which was done a few months ago through Citizens re-inspection program highlighted these pictures and marked A (toe nail) for question 4. Now today I have re-inspected the re-inspection and marked B.

Post the exterior wall connection pic.

Normal straps all the way around, 2-3 nails, some are wrapped.

It is not the interior framing they are argueing with, the photo you provided fails to meet the requirements of #4 on the form with THREE nails on one side and 1 on the other. If they reduced it to clips based upon the fact that it does not meet the criteria spelled out on the form for straps it would be a good call on their part, not so much on yours. sorry sometimes reality bites.

How many exactally like that have you called wraps Kevin?

The time for confusion on these reports and inaccurate reporting is over. If I am available I will comment as I am sure many others with experience will as well. Post the photos and ask the questions before you provide innaccurate and improperly filled out forms.

Things that make you go hmmmmmmm.

Knowing that they marked toe nail doesn’t do anything but confuse the issue. Was there another roof that had no visible tie down stapping? Like a flat roof tied into the main roof? Believe me I ain’t necessarily buying into the theory that the reinspection was done properly.

He he, I know that ya dopes. Just wanted to see who would catch it and how quickly. :wink: But my previous point of confusion still stands.

Nah, no other roof’s

things that make you hmmmmmmmmmmmmm

If the exterior wall was that accessable, then no doubt the re-inspector was doing a drive by. At minimum would be clips.

I am still on the fence about the single wrap and the 3 nail requirement. The form clearly states that 3 nails are required with 1 nail on the other side. It does not say 3 nails ON ONE SIDE and 1 nail on the other side.

When I was a framer in the '80s, every code inspector wanted min 3 nails in the bond beam strap. Two on one side and one on the other if the strap was long enough to bend over the top, otherwise 3 on one side. Most standard trusses are only about 4" -5" high at that point and the strap holes were spaced on avg about 1.5" O.C. on the older straps. There wasn’t much room to get more than 2 nails in on the strap side.

The requirements on 1802 rev 2/10 are specific.


This has been the only acceptable way to get a wrap credit since rev 2/10 has come out. Most who do these inspections have accepted this for some time now.

Wind mits have nothing to do with codes just answering the questions on the form as they are asked. The insurance companies have decided of what gets discounts and weather it meet past codes or the code of the time of construction does not matter.

Where does it say “MIN 3 ON ONE SIDE”

[FONT=Times New Roman][size=2]C. Single Wraps Metal Straps must be secured to every rafter/truss with a minimum of 3 nails, wrapping over and securing
to the opposite side of the rafter/truss with a minimum of 1 nail. The Strap must be attached to the top plate
of the wall frame or embedded in the bond beam in at least one place.
I am not quoting any code or making any presumtion that anybody is doing these wrong. I am just opening this up for debate. It really is open to interpretation.


The current accepted industry standard for single wrap is three on one side, wrapping over with at least one on the other side.

it says it right there in your post. :smiley: the first min is 3 nails then up and over with a min of 1 nail.

Well Mike, I guess it is you and me on this. I still need to be convinced that this was the intent of the OIR to require min 4 nails total on a single wrap credit. Again, the form says "min 3 nails (comma)…could mean total? I understand that it needs to wrap over the top and be secured on the other side with another nail (why highlight?)

I am just going back on experience as a builder with the requirement of min 3 nails per strap (total) and thinking that this is the foundation for the wording on the form. I think all will agree that the form was very badly constructed and ambiguious. I also know that current standards and training is to require min 4 nails for the credit. I just want to know why?

What you did in the past was perfectly correct but is has nothing to do with the question on the form.

Never try to figure what they mean just answer the question to the best of you ability.

Don’t ask why because it should not matter for the form.
If you want to ask to broaden your knowledge take one of the popular classes for the teachers “opinion” of why what is what.

The form speaks of two different minimums to be considered a wrap that will be eligible for a discount.

Minimum of 4 nails because of - 3 min on one side 1 min on the other side .

The way it used to be done is a wrap in my opinion as well but not a wrap as defined by the form. 1802 rev (2/10)

When I first started doing them I made the same decisions as you have about the wraps.
