Uneven roof tie-in problems

[mlite40]

The attached picture is the result of a new screened in deck on the back of my house.
There is a peak that exists on the original roofline that I wanted the contractor to follow so that when the new roof from the deck was put in the there would be no ledge. It appears that he built the walls to short on the deck so I ended up with this ledge.

Along this ledge is now a major issue when it rains. What is the best way to fix this problem?

I do have other pictures that were taken earlier in the construction process if needed.

Do I see what I think I see? Are the shingles bent up the face of the old fascia board?

There should have been step flashing installed between the fascia and the new roofing. This would require the fascia cladding to be cut away under the fascia board out to the overhang and the step flashing slipped under.

It also looks like the contractor used two different roof pitches causing a gradual taper of the old fascia as well. This means that as you go up the slope there would be less and less vertical flashing and therefore it would be less and less effective. Ideally there should have been ice and water shield applied so that half was under the shingles on the old roof and half was under the shingles on the new roof. You could still use the decorative cladding on the old fascia board.

Yes that is what they did. I also see bare wood between the old roof and the new roof on the ledge. I do not see any flashing placed in the ledge that has been created.

Is it possible to make a chamfer to fill in the ledge?

Missed this one.. there is a high density tapered insulation that you can get.. although it probably won't make your roof look any better... but it will even the 2 faces up to give a better "continuous" roofing job.

This very very common and a professional roofer can make it look like it was intended to be built this way, but I would tend to believe someone messed up, either architect or carpenter. The roofer shouldn't have wrapped the shingles up the fascia board.

This is how I would approach this. I would tear off 1 1/2' over fromt he joint on the lower roof and install ice shield where torn and UP on the fascia board, or even pop off the fascia board and install it on the sub fascia. I would then install baby tins (step flashing) and install the shingles properly, not wrapped up the fascia LOL Then I would install aluminum fascia capping over the baby tins. Lastly I would install a drip edge tucked under the shingles of the upper roof that will cover over the aluminum fascia cap. Done. Heck I'd even warrant a fix like this.

Rich was talking about rigid insulation to fudge the pitch so the roof appear seamless. While this would probably work, your going to need some really really really long nails to fasten the shingles through all the insulation. Also the bottom fascia will have to be built up 6-8" higher and that's going to look very odd.

This is one for the horror stories forum :) But it's fixable.
