As for Dales picture!

IMO

The top of the wall needs to have flashing on all of the flat surface!

Never stucco a flat surface and expect it not to fail over time!


It is a good thing Dale does not get the moisture and freeze and thaw cycles others do.

Some commercial buildings have cap flashing at parapets, but not many new ones.

I see no pictures with parapet walls , but what do you see Dale?.

They need caps.What ar ethey doing other than caps?

Around here they still use clay, though I am starting to see more cheap sheet metal on commercial.

Torch-Down Roll ...Bob.

Here whether residential or commercial, very seldom do they put a cap flashing on stucco parapet walls, that cost money, so obviously it's not installed---

That is beyond crazy...simply unreal---

[relliott]

So what do they do?
Just put up the EPDM and wrap it around to the front with a term bar or what?

I'm no pro by any means, but you would think that would be common sense to have sheet material on that surface.

There is a side-wall flashing at the bottom of the parapet, the roll roofing material stops under the flashing, you cannot see the flashing in this distant picture, but that is how they install most residential and commercial low-sloped roof systems where there is a cement stucco parapet wall.

Generally the roof material is cut short, in a few years the roofing material slides below the side-wall flashing's (from roof material shrinkage) and water begins to come in there also.

Top of the stucco parapets look like this at 95% of all residential here.

[Richard A. Hetzel]

The "cheap metal covering" is called a coping, and they range in quality from really cheap sheet metal to fully engineered, and expensive, extruded aluminum enameled or anodized coping systems. Or, in southwestern style, clay copings are used, which are essentially halves of clay pipes.

In the pictured instance, a flashing should extend from well under the shingle roof, and out under a coping, with a full bed of non-hardening sealant, which will allow movement from expansion and contraction.
