I've only had for about a month.  I love this gazebo.  I sat under it during a rain and it didn't leak until the rain got to torrential; and only then a small drip in an isolated area or two at seams along side panels. None noted at the roof. My guess is consumer builder flaw; not product. It looks way better in person than photographs. I added outdoor heavy duty string lights to the interior and what a beautiful glow and ambiance.  I also added a small string of colored bulbs. So pretty. As for durability; despite my initial belief that the panels were flimsy,  they're not. The frame is set in such a manner that each panel has reinforced strength because of the the number of panels to frame section ratio. All together makes for a solid design. I hope to have this for years and years.  I'm in Houston so likely no snow here; just hurricanes. Lol
