After a long wait (in my mind) the roof is mostly complete. This week the final (I hope) concrete pour was completed. The wood trusses are installed, the plywood over the trusses are installed and the waterproof membrane is on! The exception for the roof is the final metal installation.         The concrete pour was to finalize the truss supports. The contractor decided to set the trusses and then pour the concrete around the set trusses. Why?…
