Life span, installation cost and value If your primary goal is to install a roof that will last as long as possible, slate is the way to go. Slate roofs can last a hundred years or more; this is evidenced by the fact that slate roofs were still installed hundreds of years ago. The roofing materials that last the longest are concrete, clay or slate tiles. These materials significantly outperform other natural products, such as wood slats or any manufactured roofing material, including asphalt shingles and the metal covers.
Although these materials have a good lifespan, they are not as durable. Most asphalt tile roofs last around 20 years before requiring replacement. While tile roofs don't have a long lifespan compared to other materials, they're an acceptable option to consider if you're on a budget. These roofs have an average lifespan of between 40 and 70 years, making them a smart long-term investment for your home.
Once your contractor installs cedar slats in your home, you can rest assured that these roofing materials will require no maintenance throughout their entire lifecycle and will not require repairs or replacements. The NAHB (National Association of Home Builders) considers slate to be by far the most durable roofing material, with a life expectancy of more than 150 years, followed closely by clay and concrete, of approximately 100 years. Another problem related to asphalt roofs and their longevity is that there isn't much homeowners can do to extend the life of an asphalt roof. However, there are certain steps homeowners can take to help extend the lifespan of a wooden roof.
