One other thing I bought over the last couple years that has drastically helped with the ambient temperature in the house is one of those small 10ft x 10ft canopies. Was only like $100 because of when I bought it. I didn't tint to sliding doors leading to the deck because of the one dogs still jumps and paws at the sliding door, not convinced the tint would last. So I put up the canopy to shade that door in the summer, just put a few screws into the deck to hold the frame. I take the canvas down in the winter. Was like 3-4'c cooler in that room the very next day and is southern exposure.
I looked at building a proper peragula type structure half mounted to the housr but in Edmonton there is a bunch of permit restrictions to being able to do it properly and going through all of that when I need to paint the siding, and tweak the deck some to make it worthwhile the canopy works as a great intern solution until I'm ready to do those other jobs
