There are several benefits of using a tin roof. Tin is a very environmentally-friendly metal and is far cheaper compared to any other metal roofing material. Many people avoid having this kind of roof as they believe it can make a lot of noise in the rain. However, it is installed on plywood and roofing felt which suppresses sounds to a great extent. It is not affected by any kind of corrosion resulting from water and salt, and it can last for almost four to five decades.
