A composition roof is made of asphalt, asbestos, or tar paper rather than wood, metal, slate, or tile. Fiberglass mesh is often used for reinforcement. Very little maintenance is required if the roof is properly installed.
If you're worried about algae you can get special anti - algae coating done. I must warn you that this can be expensive though. But since composite roofing is about 30% cheaper than metal ones, the cost may become balanced even with this coating. add a comment
