Porch addition roof

[dhag]

Another porch on here. Seen some great stuff but hoping someone has some ideas for my situation. I am trying to figure out how to tie in a new porch roof to the existing house roof. The house is a cross-hipped roof and the porch will be in the inside corner of the L. Existing structure looks something like this:



The house roof is 4/12 and garage is 6/12. I thought about tying in a shed roof but even if I start it at the ridge I can't get a 4/12 to the front of the porch which extends 10' from the house or 2' past the back of the garage. So then I thought about a gable but I don't know how that would tie into the garage as the two slopes will meet in a dead valley and worried water will collect there. Any ideas would be helpful. Really want to avoid bribing some young architect for consultation. Sorry for lack of details, hopefully pics will explain it a little better. I've also attached a little drawing that shows where porch would go. Thanks for the ideas.

I guess old architects are out of the question...

Why do people always want to add in such places? The real answer is there is no good answer.

There are too many roofs and too many different slopes to be able to fully understand what is going on there. It needs to get on paper where it can be understood. Go for at least a middle-aged architect. This is way over the heads of young ones.
