looks like someone got a new toy (pneumatic staple gun) i know a few roofers who use them religiously. each staple is held to the other in the gun with a glue that also acts as a glue to help hold the staple in the wood when shot. that guy was just a bad shot. other than that they are good. almost eliminates “nail pops”.

Lots of framers have used staples such as those .Mostly for speed.
They have a tendency to pull out of rafters or corrode.There real purpose was /is for WALL sheathing.
Roof sheathing should be NAILED.Personally I think galvanized nails are best.
There is a fastener schedule in the IRC code book that will confirm this information.Unfortunatley I’ve loaned it out so I can’t give you a page #.
Good night

Just read Jays reply.
Those sheathing staples should not be confused with roofing staples.
We can’t even use roofing staples to install shingles around here any more.They had a nasty habit of cutting through the shingle hence the shingles wold blow off regardless of wether they were fastened in the right location or not.
Insurance companies are even reluctant to insure homes with stapled on shingles.

Cheremi. i agree with not using staples on the shingles them selvs, nothing beats a good galvi. big head, how ever if staples are used for the sheathing, i see no problem. the nails will go threw that too, and you can speed up production considerably with pneumatic and some acuracy. i can’t say i’ve ever heard of the sheathing falling off a roof or even moving at all once the shingle are installed.

Jay,
I don’t recall saying the sheathing would fall off.It will ,however ,pull loose causing an uneven surface and “nail” in this case staple “pops”.
I do recall mentioning speed.But I’m into quality.
See the IRC fastening schedual for roof sheathing.

Jay’ If you are implying I am an apprentice you would be dead wrong.
I actually thought this was a post about fastening methods.
Shawn asked fo help.I gave help based upon my
25 years of hands on experiance as a carpenter

I appreciate comments. I think Cheremie understands my concern. It is OSB sheathing that I am dealing with NOT shingles.
I am looking for something or someone that knows or can cite where using staples is a sufficient fastener.
My 2005 Florida Building Codes state 8-10d nails, but I don't know what was common prior to Hurricane Andrew as many codes changed since that storm
Thanks again everyone!

There was a time when you could use staples for roof sheating in Florida, but not any more. I dont know when they were outlawed but I think it was before 1990 They still allow this in other parts of the country I would check with the building department to find out when they stopped using them in Florida. If it was before 1990 You Need To Write It Up As A Major defect if they loose thier roof sheating in a storm and you didnt write it up You will get a phone call.
I hope this helps please post what the building department says so all florida inspectors will be on the same page Thanks

Shawn,
IRC 2003 Table R602.3(1) pg 113.
This page contains a fastening schedule.It specifically states an 8d nail should be used on 1/2" sheathing. OSB’s 1/2" equivalent is 7/16".You probably know that but just in case.
I mentioned shingles because “roofers” were brought up in a past post.I didn’t want folks to mistake roof staples for sheathing staples. In new construction it is not likely that a roofer would install the sheathing.The framer would do that.Now,if it were old and a total tear down then the roofer would of course install new sheathing.
It’s more than you asked, I know,but the issue of cutting or blowing holes in shingles with pneumatic tools is on my mind.This can be controlled by more or less pressure from a compressor.If the temperature is below 60 I don’t use my gun because the shingle is brittle in cold weather resulting in holes from the nails.
When I say staples will cut through shingles I don’t mean just at the time of installation.Over time temperature fluctuations do in fact cause expansion and contraction or movement in shingles.That staple is nothing more than a dull knife blade.The combination of the two is self evident.Now add that to just one shingle in high wind that didn’t seal down properly and you get a domino effect.
A bit off track but maybe someone can use it.

Shawn: I sincerely hope that staples are still banned on roofing and roof sheathing, due to the devastation of hurricane Andrews. We all saw the publicity that staples and poor workmanship provided.
I am not a big fan of staples for these applications and will not condone it.
Any geographical area that is prone to 110 mile an hour wind, staples should not be used. 8d nails or I believe 6d ring shank nails are more adequate for the installation of roof sheathing.
Here in Maine the standard is using 6d ring shank. 12" on center and 6" on center on the edges.

.I have had a few roofs on new construction totally removed at the client's request because visible uplift is observed.
When you are in a subdivision and you hear the rapidfire repeating of a pneumatic nailer, it's time to pay close attention in the attic!

David,
The pneumatic roofing gun is not a problem. The real problem lies in the roofer who can't read what the nail is saying hence fails to adjust the air pressure at the compressor. And nailing too high or low on the shingle.
Roofing nails can be over-driven or under-driven and in the wrong location as well by a roofer useing a hatchet.
Staples to fasten sheathing is simply not a good idea, as you said, and unacceptable.
Respectfully
Cheremie
