OSB Board

Again we have come across a rotted out OSB board mess! It seems in a lot of cases the few hundred saved is only a short term game and a long term loss. Things such as improper venting or a small roof leak, are a death warrant for OSB board. The OSB turns black likely mould and the roof starts to cave in between the trusses. We have used plywood for this reason and the fact that OSB board off gasses formaldehyde.  Formaldehyde has been linked to increased risk of leukemia and brain cancer, We just cant install such a thing in your home just because of a bottom line, we hope that when you are getting your roof replaced, and you see one bid for less money make sure they are using plywood and not OSB Board
