In Wisconsin, building codes do not require the installation of H-Clips between the 4 x 8 roof decking. There is a builder that builds homes to “Code” and we all know that may not be the best way to build a home. Most good builders I’ve talked to wished that decking manufacturer’s would make 7/16" OSB decking 1/2" shorter on the length because it would save alot of time vs trimming the ends.
I’m looking for solid support on this matter. Most of the responses I’ve received from others in the building industry says they should be used but if the roofing contractor properly spaces the decking, everything is OK.
I, Joe subcontractor, understand that Joe shingle manufacturer or Joe decking manufacturer requires the use of H-clips to be installed in order for our, Joe shingle manufacturer’s warranty to be enforcible. The use of H-clips guarantees the minimum spacing of 1/8" is maintained and will allow the roof deck to normally expand and contract with normal environmental conditions. Joe subcontractor understands , this requirement and if Joe subcontractor chooses to use alternative installation methods that are found to be below the manufacturer’s recommendations, Joe subcontrator assumes full liability and responsibility to assume Joe shingle manufacturer’s warranty on said product.
Being honest and up-front IMHO is the best thing we can do for all parties. If somebuilders/contractors choose differently, then let’s get a couple of signatures up front.
I’m really hoping for some solid help with this. and no offense intended for the Joe’s in this world.
