Complicated roof

[mweitz]

The previous owner of my house converted the porch into a sunroom. I am trying to accurately render my existing house before I go and make additions. I am having a problem with the roof over the sunroom.

The house is shaped somewhat like a T with the sunroom hanging on one side of the T.

I can get the roof correct over both parts of the T. However, when I try to add a gull wing roof to cover the sunroom, I get a very oddly shaped roof. In fact, any ceiling/roof over the sunroom causes the rest of the roof to get messed up.

See attached snapshot for the house and the missing part of the roof.

Any suggestions on how to add the sunroom roof?
