L flashing used on new roof ok?
I recently enlarged my existing covered patio. My contractor demoed my existing one. My new patio is 16 x 24. It has a gable roof. I noticed he did not use step flashing. He chalked a line 3in from the roof line and then used a grinder with diamond blade and cut through the hardie plank/board. He then used 2 pieces of L flashing (4 total) and a top piece. He then slid the L flashing up behind the hardie siding. I do have a attic ladder into the roof and I don't see any felt paper under the flashing. There is felt on the roof sheathing though. Obviously I'm not happy with his work. How much more protection would step flashing have been. It seems to me he took the easier route.

Here is some pics. Aside from the top piece looks like he used 2 long pieces. On the right side its caulked with geocel as well as the left. I'm assuming the L flashing must be 6in.

At first it looked like a pretty good install till I got to the last couple pics. Shingles should be step flashed in a wall not installed with what looks like track flashing. This will not work. Flashing is a two part equation, you have step flashing on each shingle course then counter flashing that covers the top edge of the step flashing. This really isn't rocket science, they print the instructions on the wrappers of the shingle bundles. If they try and tell you this is the way to flash a wall, tell them they are sadly mistaken.

Yes to what Oldog said.
On a side note. Does your main roof have any soffit vents? I see solid blocking between rafters and there should be a vent in every forth one.

Yes the soffit has vent holes in everyone.
What will happen if they leave the track flashing? Should kickout flashing be used also? Also there is no sheathing behind the hardieplank, that is how all the new homes in hawaii are made. A home like this goes just short of a million bucks; ridiculous. Also is no step flashing a building code violation. I was hoping the building inspector could help out.

Thanks Willing

Yes, kick out flashing should be used at the bottom. This keeps water from being channeled behind the siding. I'm not sure what codes require where you live, but shingle MFGs require step flashing. Non compliance to installation specs can void any material warranties.

Willingtolearn, What is going to be done to solve this?

I suggest you take a walk and look at other homes and check out their flashing, then go on-line and learn how it should have been done.
