Vinyl siding above brick wainscoting

Hi all -

I'm thinking of installing vinyl siding above the brick wainscoting (actually NovaBrik) on our home. In laying this out, it brought up a question of how to start the siding from the top of the brick ledge. Following a metal flashing, should it start from starter strip, or j-channel? It seems the j-channel would have a cleaner look, but also seems to have the potential to hold water.

Anyone know for sure? Or have an idea of where to find the answer?

Thanks in advance.....

Steve

Starter strip. Only reason to start in a j is if you have to rip your first row because you are trying to match a layout that started lower somewhere else on the house.

Please post a picture so we can see what your seeing.
How far does this brick stick out beyond the sheathing above?
I bend my own flashing for this one so I can make sure the flashing is run 6" up the wall, Tyvek is ran over it leaving it at least 1" above the sharp bend so it does not show below the starter strip.
Starter needs to be high enough that the siding can be laid in place and lifted to locked into place.
Most often I also do a 1/2" hem (a hem is the metal bent back over itself) at the bottom of the flashing so it stays flatter and does not oil can, (warp)

Thanks and another question

Thanks XSleeper. That's what I was thinking would be the "proper" way, but good to hear it from someone else.

I did come up with another question last night....

I'm planning to do a transition on the gable ends -right where the gable area starts. Will either do a diagonal pattern above the transition, or move to vertical board & batten style panels. How would you make this transition?

I've thought of either an "H" channel, or back to back J-channels, or maybe running a pvc trim board across the wall - and use a finish strip below, and j-channel above it.

Any idea how others handle a transition like this? Anything wrong with any of the options I've mentioned?

Thanks again!
Steve

Hi joe,

I'll get a picture when I get home tonight. It's kind of a weird layout. It's been firred out with 1 x 4's to mount the novabrick. That has continued all the way up as well. Thanks for the detail on the flashing. I would like to get this installation right.

That gap necessary between the top of the brick and the starter strip is part of what made me wonder if a j-channel would be proper. Trying to visualize it, it does seem like that will be a substantial gap.

Thanks,
Steve

Your top piece of siding below the gable will slip into either a utility trim, a utility trim that sits inside a j-channel or a utility j-channel.

You will then install a z-flashing over that, like joe was talking about. Detail your wrb over the top of this flashing.

Start you new siding 1/4" above the horizontal portion of the z-flashing to allow for drainage.

Back with pictures

Joe & Sleeper - Thanks again for your info.

Sorry to not get back sooner but been pulled away on other projects. Here are the pictures of the existing transition over the NovaBrick veneer.

Should I be able to pull off that hemmed flashing with a regular brake, or is there a better tool for that?

Any thoughts on the idea of a PVC trim board between the gable & wall sections?

The flashing that is there now simply looks like an L- flashing... I don't even see any hem on it, which is why the front edge ripples in the bottom photo. Now that we can see the top of your novabrick, it looks like it might be better if a custom flashing could be bent that closely follows the profile of the top brick... it has a chamfer just in front of your existing flashing... it might be nice for the flashing to bend down over that chamfer. You could make this yourself out of aluminum trim coil with a metal brake.

As far as a horizontal band board, if you do that it would then require 2 flashings... one below the band board and one above.

No matter how you decide to do it, when you start the vinyl siding in a starter strip, you will need about 5/8" of gap below the starter strip to hook the siding onto it.

Does this help answer your questions?
