Hello this is really an amazing community and I thank you for the add. I'm looking to build an extension type canopy for my gazebo from 3/4 inch EMT conduit. Any tips for how to build it? Any ideas on the the type of material that I should use to create the waterproof + UV rated canvas? We do get some snow here too. I want to extend the roof out about 4 feet just overhanging the wooden fence for a small BBQ station. Dimensions would be about 10'x5'.
