I'm designing a small house (rectangle) with 2 small gables on the front of the home. In between those 2 gables is where I have a porch, and I simply want to place a shed roof over the porch in between the two gables. When I try it, I get all kind of screwy roof designs. I've attached an elevation of the plan. Please help.
The main body roof is on an 8/12 but I'm going to put that shed roof over the porch on a 4/12
