I'm sort of a beginner but i enjoy the challenge. I need some professional advice on building a cover for the patio. The patio floor will be of concrete and will be 30' long and 10' wide. I currently have an aluminum cover over part of the patio but would like to extend over entire area. I would like to eliminate the existing cover and have a new one but i'm not sure on how to accomplish this task. The existing cover is attached under the eave and i was thinking about attaching to facia board so i would have a smooth roof line. Please give me some advice.
