Flat Roof Coating
I have a 10 year old house I bought 4 years ago. The year I bought it I had the roof coated with some aluminum looking stuff. It's a basic spanish style house that has two flat roof sections. The roof needs recoating. A couple of questions.
Would it be a good idea to power wash the roof before coating it. And second, what is the best coating for the money for me to use. This is going to be a DIY project.
