Step Flashing Question


Hey Everyone,

I am not sure if this is a siding issue or flashing issue. I am getting water running down behind my siding where the addition butts up to the original home. I attached a photo of where the water is coming from under the siding as well as how the roof looks. I initially extended the downspout to try and divert the water away from the corner but its still happening. Any help or suggestions would be appreciated. From my research it looks like I need a a step flashing diverter but I wasn't sure if this is correct or how to install.

Thanks
CDM

Step Flashing Question


It's called a kickout. It has to go behind the siding and behind/under the first piece of step flashing to work. http://www.nachi.org/kick-out-flashing.htm

Step Flashing Question


Both the step flashing and J on the roof should direct
water over the face of the siding.

Step Flashing Question


So do you both agree that the reason for the water getting behind the siding is due to the lack of a kick out. Is it possible to just remove a few pieces of the siding to be able to install one?

Thank you for the photo by the way.

It's probably the most likely reason and remedy.
The siding can be" unlocked" near the flashing and properly repaired.
Any local building supply outlet should have the tool designed for this.
While you have the siding pulled out,check to make sure the house wrap
extends over the top of the step flashing.

Here's how we do it, a purpose made pvc kickout unit. This wall is ready for new siding. (the wood battens on the outside of the house wrap is to create a drained/vented cavity behind the siding, which is a requirement here nowadays on many homes)

Siding can be unlocked and the kick out installed.

No special tools are required to unlock the siding but the unzippers do make it easier.

Great thanks guys for the quick response. I will give it a try, I already have one of those siding tools, had to remove alot of siding to replace a sliding glass door that also leaked.

Step Flashing Question


My sider likes to use the little mini wonder bars to pop off plastic siding.

We've installed many kick outs diverters without taking the plastic siding off the home. You first put the kick out were you need it and make a line were it goes against the siding. Then you use either a straight edge or a good pair of tin snips and cut up from the bottom. Some times you also have to cut the j channel sometimes you don't. Once it's cut you then have to push the new piece of flashing up under the bottom most shingle tin (step flashing). To finish it off you put some good quality caulk on the back side of the diverter to siding spot.

Good Luck!

BTW, kick outs or diverter flashings have been code here in MN for several years.
