I know this is long and there are more important things in the world, but when are we ever going to be able to address this nail-gun controversy again? From a reader who knows more about nail guns than I do. No, really he does. He is now my anti-nail gun guy:

Please don’t go too far down the road with the nail gunners. Nail guns miss and because they give no feedback the carpenter is often unaware he missed the roof truss. The problem is very well documented. I wouldn’t be in a hurry to buy the construction industry line.

“Now with that said, look in the area where the roof sheathing attaches to the roof trusses. How many sheathing nails miss the trusses? If too many missed you have problems. Your roof may be in danger of coming apart because of uplift from the high winds generated in hurricanes. So how many is too many? That’s hard to say, in the old days contractors used framing hammers to nail down the sheathing. When a nail missed the truss they could feel it and would just drive in another nail in the correct location. When building today’s homes most builders use nail guns. They are powered by compressed air or in some cases a small .22-cal. charge. While it’s quicker and more cost effective, there is a greater chance the carpenter won’t know he missed the truss and will just move on. When they build my next home I will demand that nail guns be banned from the job site! Many homes lost their roofs because of this problem and it’s not a cheap to fix.”

“Nailing everything to chalk lines is another luxury on-site builders would like to have. The advent of nail guns increased productivity but left operators of the gun unable to tell when nails miss their mark. Chalk lines keep the nails on target but, in most instances, aren’t practical on-site.”

“Power nailing has become common because of its speed. One problem with power nailing is that the nail gun operator cannot always tell when he has missed the joist. A nail which barley misses or barely hits the joist will not hold the panel flat against the joist. As a result, when the panel deflects, the nail can rub on the joist and cause a floor squeak.”

“Attachment methods can have an effect on the uplift resistance of sheathing. Riba, et al. (1994), noted after Andrew that some panels appeared to have pulled loose after fastener heads pulled through the panel. They hypothesized that this may have been due to pneumatically driven nails that have only a partial nail head to accommodate the nail collating system on power-driven nail guns. When staples were used, cases were observed in which one leg of the staple missed the underlying truss or rafter. This reduced the strength of the connection by at least 50%. Some staples showed evidence that the staple was driven through the sheathing with excessive force, leaving only a partial thickness of the sheathing to resist the wind. Power nail and staple drivers must be properly adjusted to avoid this problem.”
“Problems to Watch Out For When Installing Roof Sheathing
Much has been learned from the experiences from Hurricane Andrew. Contractors installing roof sheathing should be aware of the following potential problems:

If gun nailing is used, the chance that the nails may miss the roof structural member below increases, a critical component in roof sheathing failures in past hurricanes. The bottom of the roof sheathing can be easily inspected for driven nails that have missed the roof structural member, and it is important to re-nail any sections that have been missed.
If gun nails are used, there are several things to be considered. Power-driven nails generally have a smaller diameter shank and are sometimes shorter than common nails. Power driven nails are allowed by the code. However, if their diameter and length do not meet or exceed the dimensions given by the code, the nail spacing must be reduced accordingly to compensate for the smaller size.
Some types of power nail guns use “clipped head” nails (also known as modified round-head nails and P-nails). These are nails with heads that have a portion of the head removed so the nails can be packaged tightly together and still be driven.
Because the heads are smaller, it is easier for the roof-sheathing panel to be pulled off over the nail head in high winds. Gun-driven nails are available with full heads. These should be used if nail guns are the chosen method of installation. The building codes in Broward and Dade Counties require roof-sheathing nails to have full heads.
Don’t take their word, or the insurance companies, or the building code reinforcement officials, just go home tonight and look in your attic (if built during the pneumatic nail gun era). How many roof joists did they miss?

Me: The obvious question: Can we put frickn’ nail guns on sharks heads?
