Rafter tails

So I had major leak problems and discovered some pretty obvious places I was getting water from. There is a 811 enclosed porch or sunroom or whatever you want to call it off the back of my house. The roof of the room extends out from my existing roof at a pitch that I know is not right
btw it is a flat roof with asphalt shingles and I have been told it should be either a gable or rubber roof. Where the rakes met the roof there was bare wood touching the existing roof. It was all rotted and there was no flashing coming up the side. I re roofed it flashed it and made the rakes PVC instead. So now I strip the old cedar shingles off the porch and the whole front side of it was completely saturated. The sheathing was so wet I had to remove it. I'm talking when I hit it with my hammer I got splashed with water. So now I am putting new sheathing on and I get to the top and I realize that the sheathing runs directly flush with the fascia board. There are no rafter tails over hanging the exterior wall. Should I extend the rafters is it possible the water is coming off the roof behind the gutter and right behind the siding and into the house?

Unfortunately you are the only one with eyes on the project but from your description is sounds plausible.

The whole intent of shingles, drip edges, overhangs, sheeting, underlayment & flashing is to shed water away from a structure, take a short cut and then you get a mess!

I don't know what the point would be when it sounds like its all wrong to begin with, unless you plan to put epdm on it when you're done repairing it. You shouldn't use shingles if it is less than 2:12.
