I turned my garage into a full time woodworking shop. Even screened in the overhead door to keep out flies and mosquitoes. There are times when I need to work on my cars so I had one of the free standing car ports put on my driveway. It has been up 2 years without a single problem. I had them set it with one end right up against the garage and I sealed it with spray foam. I can go in and out of the garage for tools and such without getting wet when it is raining. LOL
