overall the only gazebo I've seen that should handle Buffalo NY snow.\nThe Bilt app is a real help.  part numbers stamped on board edges are nearly impossible to read.  Removable stickers would be a big help.\n99 % of pre drilled holes line up.  overall would recommend, but installed myself because the installation company (Go Configure) stiffed twice. \n built roof panels in garage and had 4 adults install roof sections.
