Does anyone know how many inches or feet from the roof the "canopy" cloth should sit to give it an adequate air pocket to work?
Ok. I've got some possible ideas for creating a fast, temporary canopy on my flat-metal-roofed run Today, from materials that I already have here. I'm trying to think through them carefully to see if any of them seems ineffective or even dangerous!

If so, plan B is to run out and get a ready-made one and try to rig it to fit the size of the run asap.
First, the sturdy garden shade cloth I ordered finally came in! It's dark green. I also have some large outdoor curtains that used to go around the pergola - 2 light brown, 2 cream.
I have an old leftover partial roll of chicken wire, & the same of cattle fencing (the cattle fencing was light enough for me to shape a couple mama heating pad caves for chicks).
I'm thinking, if I can make a few large semi-circular wire shapes (short arches), set them spread out on the roof, with a bit of Gorilla tape on the tips to secure them just a little, then I could arrange the cloth on top and secure the cloth, using clothes line, to the corner roof posts and even to the hardware cloth wall right under the roof. To make it happen fast, I would just use those metal office clips to join cloths together (leaving a few gaps where light would hit, I'm sure, but hopefully very few).
That way - if I can get it to work - I'd have cloth up several inches from the roof, with an air pocket between the roof and the cloth.
PICS are of the building as it currently looks, & of rough sketches of this possible design. *But I just noticed I Barely drew the cloth stretching across the top!*
An alternative could be quicker & maybe a little easier to arrange: use maybe 5 large but lightweight tree limbs (limbs with some multi-directional branches & maybe leaves projecting outward) that have already fallen or that I could cut from my surrounding woods. Set them down, and secure the cloths on top the same way. My question about danger comes from this idea of adding dead branches to the metal roof in our hot drought. My concern might make no sense, I don't know!
NO PIcs of this idea.
Hopefully you can follow this. Thanks for any constructive criticism & suggestions.
