Metal roofing is becoming a very popular option in Washington State. Metal roofs are durable and can withstand ice, rain, wind, and snow. There is little maintenance with these roofs and they can last up to a lifetime if properly maintained. Plus they are made up from recycled materials.
Although they are very good roofs to have on your house there are two main disadvantages to this type of roof, rusting and less cell phone and radio reception. If properly maintained and coated then you can prevent the rusting. Most manufactures warranty a period of time of no rust on their roofs and also give a fade warranty. After this warranty expires then it is a good idea to have the roof recoated to get the full life out of the roof. As for your radio and cell phone reception, maybe a skylight will fix this problem above your favorite chair.
