Put overhang with that tin and leave open areas under the overhang, the more the better. Just cover it the open areas with wire to keep predators out. And make your roof high enough that the roosts have some separation. During the day it will get hot but at night when they are sleeping it won’t be too bad. Tin can work even in hot climates like yours but you need plenty of ventilation up high and down low plus build it tall. If you build it tight and small, yeah, that could be bad in the sun like you have, but big and open works well. Horse loafing sheds are often built out of metal, roof and three sides with the fourth side open. You could easily do that with a coop where you are, three solid sides with the fourth side wire. Save some money on the wire side.
I also just added plain clay dirt to my coop floor, just built it up so rainwater runoff can’t come in. I also put in a swale on the uphill side to divert rainwater away from the coop.
I think an open area section next to your existing coop is a great way to go. Chickens don’t worry if the space is in a formal living room, a den, or a game room with bath. They just need extra space they can use when they are awake. It doesn’t matter if it is in a coop, coop and run, or some other combination. Just make sure the space is available and they will do great.
I’ve seen chickens sleep in trees in below zero weather. They were not sleeping on a bare limb overlooking a bluff squawking defiantly in the teeth of a blizzard. They were in a protected valley in a thicket where they could move around to get out of a direct wind. They really can handle cold really well. Your heat is much more dangerous that zero degree weather if they have just a tiny bit of protection.
