We typically seldom encountered face nailing of vinyl siding until recently and now we are encountering it repeatedly on new construction. We are even being told that some code enforcement officials are saying that it is acceptable and not a problem. Contrary to popular belief, when it involves manufactured materials, the code, and the code enforcement officials, are not the authority, the manufacturer is. A manufacturer not only trumps code, but if issues concerning their product are not adequately addressed in code, their instructions and recommendations literally become code. SURPRISE!
With exception of a very few limited circumstances, face nailing of vinyl siding is never acceptable. The reason is that vinyl siding expands and contracts with the temperature and provisions are made with proper attachment for that movement with slots and nails which are not supposed to be installed tight. Note bulging and ripples in home with vinyl siding. Not installed properly to allow for expansion and contraction of the material.
Our inspector, Josh Hedges, is the one this has been coming up with lately so I suggested that he do a little research last night. This is what he came up with. Read for yourself. Click on the photo below.
