I'm building a portico roof over my front door. The roof is flat and measures 4' X 8'. It's 8 feet wide and 4' off of the house. Right now I have it pitched away fom the house 1" in 4 feet. My concern is how it looks. If you look at the side of the roof, you can really notice the pitch. I would like to change the pitch to 1/2 inch over the 4'. Any ideas/suggestions would be appreciated.
