I love this - exactly what was needed to increase quality outdoor living space. The polycarbonate roofing is very lightweight, which was surprising, but it is sturdy. In Pennsylvania, snow is a concern but this has a load of 2500 lbs! We built it in two days because of rain. Four hours each day - the frame the first day and the panels and finishing the next. Two people - both of us are handy. Do not use a drill the screws will strip. The allen wrench works but oh the thumb pain later! It is so nice. The directions were pretty straightforward but make sure you read them ahead of time. It is pictures with little wording. We used two step ladders and worked in tandem. It was a pleasant project to do together. Now to set it all up and decorate. Really looking forward to enjoying this addition to the patio.
