Flashing

[new land owner]

I shingled my roof intersection to the main camp and have come up with an issue.  I did step flashing but I am not sure what to do where the roof intersects the wall and I add my 1" rough siding?  Now even thought I am flashed and no water will enter the building I have an issue that the water will go behind the siding and cause issues?  I have goggled kick out flashing and that seems like what I would have to do?  I was wondering what others have done to solve this issue.
Thanks

Yes you need a kickout, you can either fold one like one corner of a Christmas present wrapper or they sell premade ones on the net that work well.

But
First, remove the siding, I hope you haven't gotten too far. Think like a raindrop. The raindrop has penetrated the siding above and is running down the tyvek, it gets to the step flashing and where does it go? Behind the flashing, IN!

The tyvek needs to be slit and laps over the top leg of the step shingle. I don't use those short steps but I guess they work. I make them out of 12x12 squares of colored metal bent in half.

I then lay a 2x4 on the roof and use that as my guage to keep the siding up off the roof to avoid snow and leaf rot. The bottom edge of the siding gets finished well, this is a real trouble spot. The reasons for my using colored metal and big step shingles then makes some sense, I'm exposing more flashing than you have.

I usually put a piece of flashing flat on the wall prior to bringing in the minor roof, fascia and drip, and turn that out on the top of a siding row below, just one more layer.

Thanks Don

      What you said make alot of sence.  I will have to pull off some of the siding but it should not be too bad.

I just spent a week at camp working on more siding.  I solved my flashing issue by making my own "kick out flashing"



I then put a cut in my siding



And this is how it looks complete.



We did have a small amount of rain while I was there and it seemed to work well.

Hope I am not nitpicking but better fill in the saw kerf with calk,  and fill in where the siding did not marry up real well.  That said WOW you did a great job on the flashing

I have bought more caulk to do just what you said.  Thanks for the feedback.
