Trends change everyday. I am not talking only about fashion design, but every aspect of our lives. From how we behave and interact with each other to how we choose to live, our creativity and things we consume. No exception are roofs. While metal roofs remain the most preferred type, throughout the years we have seen new types and styles get momentum. Asphalt and flat roofs are very popular as well, but in recent years eco-friendly environmental roofs are getting more traction as government grants subventions and people are becoming more aware of global warming.
