Shiner Nails- code violation?

Another example of the 1802 over-writing the strongest code in the country… :mrgreen:

In other news…Eric is going to mow his and his neighbors lawn!

Have fun :slight_smile:

Are you sure it was not re-nailed?

Do you think two layers of 30# is better than a self-adhering, self sealing modified bitumen?

I have had to have nails backed out and re-nailed because the JHA wanted to make sure the area was nailed.

The inspectors that have never built a home do not understand that it is not always the framer not knowing where to nail or how to nail in a straight line.

Some reasons why they may miss sometimes.

Wood is not always straight, even in engineered trusses.
Plywood/OSB not straight,
Trusses bent while installing because of the lifting from the crane, even wind
Walls not straight, plumb or out of square
Foundation off.

When possible they should be removed, and for the most part(now) they are. This is near impossible on a re-roof, so get over it.

The biggest issue was framers moving from hammers to nail guns. There was a lack of training and a learning curve. This is one reason why there are wind mits now.

Understanding how we got where we are now goes a long way to understanding the building codes and wind mits. They do heed each other but the do not correlate.

John;
I understand that there is a adhesive type foam that can be applied to the underside of the sheathing…just on the joints between the trusses and on both sides of the top chords, that achieve the secondary means of waterproofing required…true?
Not Icynene, it does not apply here…for sure.

Also I believe that you cannot use 4" strips of Ice and Water Shield on the joints if hot tar is to be used…even if over tar paper…because of the heat…true?

Minor points but just would like to know if I can count on these facts, in your opinion.

For the code you should talk to the AHJ.

For a wind mit you can use the 4" tape or the spray adhesive to achieve the SWR. The AHJ may not allow hot tar with it, especially in your area.

In my area, only one layer of felt is needed on a 4/12 or greater (two ply for low slope). Self adhered is installed only as an option.

I checked Preston. The only thing left on those trusses were the original staples. Roofers don’t usually check for misses when they reroof. And if they did, it would be too late as the dry-in guy is right behind the nail guy.

And one other thing I always say to anyone who brings up this scenario, If the guy didn’t know he missed, and can’t nail where nails were already present as a guide, I find it highly illogical to assume, that he would have the wherewith-all to go back and re-nail. :smiley:

Someone who is listening can hear a difference.

The “Nail Whisperer”? :mrgreen:

I agree, a good framer can immediately know if they missed by sound or the the recoil force. But we are talking about roofers here (usually the laborer), with 20 guys on the same roof making noise. They just don’t give a sh it.

Table R602.3.(1) lists the code required fasteners for different types of structural members.
Roof sheathing 5/16 " - 1/2" and 19/32" requires 8D common nails. If you are in a region having a basic wind speed of 110 mph or greater, than 8D deformed nails shall be used for attaching plywood structural panel roof sheathing.
