Metal Roofing Materials. Metal roofing materials can last for decades without degrading in appearance or function. The oldest metal roofs in the world are over 120 years old and are still in fairly good condition. Paint and anti-rust technologies increase a metal roofâs lifespan drastically and make metallic roofs an excellent long-term investment. Residential metal roofs typically have a rated lifespan of 50 years or more. This is outstanding compared to the 15-year average lifespan of other materials.
Your house. The aforementioned Study of Life Expectancy of Home Components report states that a typical roof made of asphalt shingles should last about 20 years. Roofs made of fiber cement shingles should last 25 years, and roofs made of wood shakes are typically good for 30 years. If you have a roof made of slate, copper, clay or concrete, you can expect it to last 50 years. The foundation and frame of your house should last a lifetime if they were properly built. And while the walls should also last the lifetime of the house, aluminum windows are only expected to hang around for 15 to 20 years. Wooden windows should last as long as 30 years. Your garage door opener won't have as lucky of a fate, however. Expect it to last 10 to 15 years.
