Kick out flashing

GROUNDUP | Posted in General Questions on

Hi there. I notice water dripping down my siding at the wall to roof connections. Obviously this is an issue with the kick out flashing. Here is what is currently there which is not sufficient. The house already has Henry blue skin wrap behind the siding. What’s the best way to fix this correctly? Do I need to remove the siding and some roofing or can I add on to what’s there? Any specific products to use? Also can a handyman do this or do you this I need a roof/ gutter company? Thanks for the help!

    That looks like a standard step flashing piece. A kickout flashing is much bigger:

    That ship has sailed but it is also generally better to keep the siding a ways up from the roof surface. When it is that tight, the bottom is always sitting in some water and tends to wear out much more quickly. If the siding is up, there is also more room to properly install the step flashing under the siding counterflash when you need to re-roof.

    In your case, I would try to take off the course right where the kickout flashing would go and install the proper kickout.

      Thanks so much. Question. Just read about reverse lapping and that the step flashing needs to go under the house wrap. We have blue skin. Do you think we can lift it and install step flashing under or if there is step flashing the diverged pierce? We have this issue at all wall/ roof areas. Like this pic. Thank you.

        With a self-adhered WRB you don't need to be as worried about water draining behind it, so in a retrofit, rather than try and lap it over the step-flashing, you can use a strip of flashing tape instead - much as you would if you were using Zip.

          Makes sense. Thanks so much for the help
