Beating an old dog here

New Construction - 2006... Roof decking is 7/16 OSB (Stamp rated at 16/24) Trusses at 24OC, No plywood (H) clips installed. Since its stamped for 24OC, and the trusses are at 24OC would you infer that the lack of H clips is no big deal or within the manufacturers specs?

Peter,

Because you asked the question I would assume that you would recommend them. So what would keep you from recommending them?

I would.

Nobody's gonna put them in at this stage of the game but so what?

[Peter Doane]

I guess my point was,.. its installed within the material accepted guidelines (i.e. by the APA stamp on the OSB for 16/24OC span.) If I called out a "lack of H clips" would the builder/ contractor make you eat crow by pointing out the very obvious,... i.e. the APA stamp?

[John Onofrey]

The answer lies in table R503.2.1.1 (1) of the 2003 IRC. Looks to me it could go either way. No big deal as you say.

It is recommended for the H clips - but sounds like it's all done within manufacture specs, as you stated. Not a big deal, it allows for proper edge spacing & should be fine. Your call!
