The process of roofing finds its roots way back in time. This is because placing a roof on the top of your head means having protection from external factors. The feeling of having a private life, to feel protected and isolated from the big world out there is implanted in our DNA since the first ages. And humans achieved such a thing by building houses and placing a roof on top of them to isolate themselves from the rest. A few years ago, the only roofing options were asphalt, slate, clay, or concrete shingles.
