Quality of work from Bertram construction is very, very low. Had Bertram Construction install a new metal roof. Finished work looked like it had been hailed on due to screws being drilled in too far, plus there were multiple scrap pieces of steel roofing used on short sections. Furthermore, they hammered the steel to bend it on the edge of the hip. I have seen other roofing jobs done by Bertram Construction and they are all sub-par, even after Bertram has been doing this work for 5+ years. Looking at any other steel roof upsets me, as I think about how bad of a job Nate Bertram and his crew did.
