The 13 ft x 10 ft Aluminum Patio Gazebo was pretty easy to set up to the time to install the metal sheet for the roof. I wish the instructions would advise an easy way to install. The angled pieces were the hardest because the one side would come out of the grooves. Also, screwing in the first tier roof, reaching in between the gap of the first and second tier was unmanageable. The gap has to be bigger. Finally, more hands make for easy and light work. Once complete, it’s a great looking product.
