I did what you're wanting to do, with a tarp that's silver on one side to reflect the sun. It's re-purposed from one of those portable garages the wind tore up, and is better quality than what you're likely to find in most places, so it's fared better than most, for 3-4 years so far. The silver is great. Maybe you can find replacement panels for one of those buildings.I decided to cover most of the roof over the run with a tarp. Run is 10wide X 20 long
They had one big enough on sale so I grabbed it.
Now I am having 2nd thoughts on the color..........it is Silver/Grey.
I didn't want the Blue because I just don't like the way it looks.
Does the color really matter? I WAS hoping to find a White one but that is not possible.
And I don't think you can spray paint the tarp and have it stick for long.
