　　After having been involved with metal roofing for nearly 10 years，I have developed a true appreciation of this roofing material，and I would like to point out some wrong assumptions about it.

　　Some people think metal roofs have a higher risk of getting struck by lightning.Actually metal roofing does not increase chances of your home getting struck.Instead，if your house does get hit by lightning，metal roofs will help to curtail the damage and your roof will not catch fire as metal doesn’t catch fire easily.

　　Will metal roofs make a lot of noise when it rains？Modern metal roofing is typically installed(安装)over solid wooden boards.With them，your new metal roof will not make much noise.

　　It may seem like metal roofing costs a lot of money，but if you look at the cost over a long period of time，you will realize that it is actually the best investment a homeowner can make.A metal roof installed right is a very longlasting roofing system，and it may well be the last roof you will ever have to install on your house.And it will also help you save significantly on your cooling costs.Metal roofing can result in up to 35 percent savings in energy costs during summer months.
