Help me pitch my flat roof!
November 3, 2013 in Design Dilemma
We are buying a home that will need a new roof immediately. The roof is flat and the entire second level of the home is mansard style. I do not understand why a flat roof costs so much to replace. Estimates range from $12,500 to almost $30,000. It seems to me a simpler solution is to attach beams to the upper portion of the mansard and go across the current roof at a 1:12 pitch then deck and cover in roofing metal. Why do we have to go the complicated, costly membrane route? Thanks.
