I’m residing and installing new windows on a 1972 “contemporary.” It now has two layers of T1-11, one installed without any flashing by a previous owner. It’s all coming off down to the studs, then we’re fixing any nasty framing surprises and installing half-inch sheathing, stucco wrap, the windows, and Hardie-Panels (4X8 cement fber sheets resembling the original thin T1-11) for the final siding. We’re adding two round windows in the bathrooms that now have no windows. The new units are non-venting molded structural plastic with molded integral brickmold on the outside. For the new rectangular windows, we plan to install sill pans, properly wrapped housewrap (stucco wrap in this case- it has vertical wrinkles to provide a drainage plane), and Dupont flexible and straight adhesive flashing.
The question is, what’s the best way to detail and flash the round windows? They install by screwing through the integral brickmold. I’m considering finding a sheet metal shop to make custom drip flashing for the top half-circle of the windows, but if there’s a simpler way I’d appreciate some ideas.
Thanks!

I frequently make these from copper.
Like the Tucson, I shall rise again from the ashes.

Excellence is its own reward!
we flash with Grace membrane....
then we apply our casing trim...
then a drip edge of the appropriate color of aluminum coil stock.. this is clipped on the back..
the clips are bridged by Grace membrane (so it's concealed)
and the siding goes over the alum. dripedge
