These roof systems are considered the best of the best in today’s aluminum construction industry. These systems are a structural design which means you can add outdoor lighting or fans directly to them. They are extremely strong but still very lightweight. The best feature of this roof system by far is the insulation factor. Unlike the pan roofs, these dramatically decrease the heat transfer from the sun, so that means you won’t feel the heat through the panel like you would the pans. If you aren’t able to have a roof height of at least 8ft, then this is a highly recommended option.
