I live on the top floor of a house. The South and West are both open, meaning there is no house there to block the breeze. Or the direct summer sunlight! This makes the concrete on the West side of the house, and the roof boiling hot. Stepping in from the outside is like walking into an oven, literally how visitors during summer describe it.
I would like to know how to insulate the rooftop and Western wall (top floor only) so the direct sunshine doesn't make it feel like I'm headed to
Venus and yet we stand tall Mars. Seriously, it gets insanely hot and there are a few hours of relief, before the dreaded sun comes back. I thought about providing a green tarp cover across the roof. This would provide a covered area to sit on the rooftop as well, which is currently unused. And any plants I set there are incinerated by the sun. The expensive part of this effort is likely to be the initial structure (metal poles).
Are there alternatives to this method? And what about the wall? Any way provide shade to at least part of the wall? I am concerned about the aesthetics and cost matters!
I am sure I am not the first person to face this situation. I am burning to hear your advice.
