Roofs with asphalt shingles and wood shakes should last 15-25 years on average, while metal and tile roofs tend to last even longer. Metal roofs have been known to last up to 50 years, and concrete tiles may last as long as 40-75 years. Several factors determine your roof’s lifespan, including the installation process and the quality of the roofing materials used. Maintenance is also a key factor. However, even with the proper maintenance, your roof isn’t invincible. Years of direct sun and exposure to the elements can take a toll on your roof. Hail and high winds can be problematic, as can ice and snow build-up during Colorado’s winters. Too much moisture from leaks can lead to mold and algae growth. In general, dark-colored roofs may wear out faster than light-colored roofs due to the amount of sun beating down upon them.
