Rod came by on Sunday and gave me a hand with the roofing--his years of experience putting roofs on barns came in handy!
Why white? Maximum sun reflection, minimum heat retention, and I can harvest the water for use in the house. I ordered the steel to the specific size that I needed, that way I only had to cut one piece on the main roof, then three separate pieces on the bay window area, rather than having to cut every single piece to size.
Why steel? It's easy, lasts forever, and I LOVE listening to the rain falling (which is a lot here, so I might as well enjoy it....) And, when the sky is clear, you'll find me sleeping on my roof under the stars!
