I have an L- shaped brick home with a concrete 9'x30 back patio that I would like to cover. The roof on the 30' side is has a 10/12 pitch and the other roof 9' side is a 6/12 pitch. The 30' side has a garden double doors that water floods under, so I either need to place gutters or cover the concrete patio. I can't add the patio to the top of the other roofs because my chimney is about two feet up on the corner of both roofs. Also the 30' roof is not only very steep but it is Hugh the water coming off this roof would probably flood gutters. I hope some can understand what I tried to explain and have some suggestions.
