I have been contacted to review a two story cottage that was left unfinished. The weather has provided rain and snow since October of 2012.The main floor is on as well as the second. Unfortunately the roof was not! Both floors are made of 3/4" OSB and are dirty and,in some areas, swollen. The rest of the building requires some adjustments but for now the flooring and roof would be the primary concern.
My questions are whether it is advisable to go over the existing flooring or cut and piece the OSB with 3/4" plywood. And of course the roof.
It is a bit of a nightmare but probably fixable. Any suggestions?
