Another image added to the free Gallery: Sidewall Flashing


I would think one would need step flashing, especially with shingles, eh?


I would be 100% agreement if it was a sloped roof such as this…

The image Nick posted looks more like headwall flashing like these
headwall flashing 1


Except the roof depicted is totally flat and has a kickout … Doesn’t make much sense. I think some tweeking of the graphic is in order.


I’m thinking that it is intended to portray a sloped roof but needs modification. Why else would one need a kickout flashing?


The new graphic sucks. Back to the drawing board.


What specifically is wrong with it? It does not need step flashing BTW. So I don’t see any error in it.

What roofing material ist it suposed to portray flashing at a sidewall?

I would think the flashing material is aluminum.

What roofing material is it supposed to portray being flashed at a sidewall?

I think the underlayment would be paper or felt?

Then what is the point of the image regarding flashing?

To show how the flashing is installed?

The way I see it, it is installed differently depending on the roofing material.

I guess it could be some synthetic underlayment, but because it is black, I’d say it portraying asphalt-saturated felt??? Felt is still very common.

So, the “asphalt-saturated" felt is the final roofing material?…doesn’t make sense to me.

A metal roof might be different.

No, asphalt-saturated felt wouldn’t be a final roofing material. It would normally be used under shingles.

And, as I said in post #2:

The image simply isn’t clear.

No. Not necessary. Step flashing would only be necessary if the roof was angled up the sidewall.

It’s not angled up the sidewall. Look at the building wrap. Building wrap is installed horizontally and the image shows it parallel to the counter flashing and flashing, which means the roof/sidewall intersection, counter flashing, and flashing are also all horizontal. I think that’s why the artist gave us the bigger image next to the detailed one in the same graphic.
