In the past we've had soft/canvas top canopies that either collapsed from rain, blew away from wind, or deteriorated from constant sun, so decided to get a hard top and bolt it to the deck .  We live in NJ, our deck gets 9 plus hours of sun, you cannot sit out there without shade.  It has only been up for a week, so time will tell, but we have high hopes for it.    Hopefully, it will get thru the winter and be ready to keep us in shade next summer.
