Overall very good kit. I’m an above-average handyman w construction experience. Having the right tools such as good drill, impact drill, extra construction clamps and hammer drill for concrete is important. Three strong people for roof install is a must. Not just for lifting but also moving the roof around to get it all square and booting together. We had some big gaps between roof panels that required moving panels and clamping hard.  BILT app and paper instructions are very good. Blue plastic covering on sheet metal is a bear. That took an hour or more all-in peeling off the plastic as it tore in small pieces. There must be a better way to protect the metal. I’m a little concerned about the “corrosion resistant” metal. Saw some evidence of rust already and the panels get scratched a little during assembly. Plan to get brown touch up paint to cover scratches but hope the roof holds up for more than year or two!  The pavilion looks great and seems sturdy. Overall I’m very pleased.
