Metal is such a durable material that most manufacturers now warranty their roofs for a lifetime. Never having to replace a roof is a big selling point for homeowners. Another advantage to homeowners is that it generally can be installed over old roofing materials. This eliminates costly disposal fees and helps preserve the environment. Metal roofing also can maintain the look of a home while reducing the maintenance.
Cedar shakes give a home a unique, rustic look, but can require expensive treating and replacement.
In some areas of the country, concerns over the spread of fire even have resulted in the ban of the material. Metal products available today actually can replicate the look of cedar shakes. Homeowners are not the only ones being attracted to metal. Architects are specifying it in increasing numbers. With the wide variety of colors and styles, metal assists architects in achieving a look not available to them in the past.
