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.
2 thoughts on âHow long does each roofing material last?â. 1  i have a 3 ply fiberglass mat roof coated with white elastomeric coating. 2  We are looking to get a new roof and are wondering how long we will have to live in this house to get our moneyâs worth out of the investment. It is good to know that asphalt roofs should last from 12 to 30 years. Thank you for informing me that the life expectancy of a roof is also dependent upon the thickness of the shingles.
