Framing A Portico Onto Existing Roof Line


I am framing a portico onto an existing roof line. There are two different roof lines and I am a little stumped as to how I would tie the whole thing in...mainly because of the roof line that sloped in opposite direction
(I have attached photos of existing).
Portico will obviously be centered over entry door, and cover will extend 3 feet to left and 6 feet to right of door.

Any help is appreciated!

The best advice you will get that you dont want to hear is to hire a professional, at least to design it for you

first you got to figure out what you want, 3 feet to one side and 6 to the other sided of the door is not centered on the door

Build an existing model of the roof out of cardboard, then start putting bent pieces of paper on it to represent the new portico roof. Biggest problem will be the cricket on the right between the old and new roof.

This all depends on what roof us going over the portico. Quite a few use a flat roof. Could be gable, hopped, triple gable, etc.

Make a blind valley, and I guess that's the roofer's problem...

Good advice, nothing like making a model to clarify what's going on and options...............

I solve these things with google sketch up. The cardboard thing is a simple visual.

Gable roof will be tricky and require a cricket valley

Thanks for the input. Plan is to do gable roof with a 5:12 pitch (or whatever pitch is on existing roof.
