I've had my carport canopy going on 5 years now. I have it in the front of my garage to cover my SUV. Let me tell you, I've only had to replace the canopy twice on this bad boy. I leave it up year round and during the most recent snow store here in NYC where it dumped 2ft and then 3ft of snow on us, this canopy STOOD albeit with some 2x4's to fortify the roof. I also use rachet straps and a hook screwed in the ground to hold it in place. Love this product. I just wish they made it in a 8ft or 9ft wide frame so I can put one in my narrow driveway.
