Weather Vane Roofing

Flat roofing isn't truly flat, it's very lowly sloped and appears almost flat. It's common in commercial buildings because it's energy efficient and an easy and cost-effective way to roof a very large area. There are three types of flat roofing systems: membrane roofing, built-up roofing, and modified bitumen roofing. Flat roofs are challenging to maintain in cold weather and need to be replaced more often than sloped roofs.
