Knowing how long your new roof is expected to last is very important during residential roof replacement. Different roofing options have their own strengths and weaknesses. As a result, they also have different expected life spans. This is why we came up with a brief overview of the three most popular roofing options available to you.
Asphalt Shingle – 18 or 30 Years
The most common roofing material is actually divided into two main options: three-tab and architectural shingles. Three-tab shingles have an expected lifespan of around 18 years, while architectural shingles can last for 30. Getting the most out of an asphalt shingle roof relies on detecting signs of early shingle problems such as curling and individual shingle replacement.
Metal – 45 Years
Metal roofing is strong and versatile, but earlier metal roofs had shorter life spans because of their susceptibility to rust. Today’s metal roofs are barely affected by moisture thanks to new manufacturing techniques and the development of more effective protective coating. Metal roofing systems tend to last longer by having their protective layer checked on a regular basis to see if they need a fresh coat.
Wood – 40 Years
Wood roofs are available in the form of shakes or shingles, which may require more care than other roofing options. Treated cedar wood can last for a few decades if you have signs of wood rot addressed right away. Wooden roofs also tend to last longer in less humid areas or those with generally sunny, dry climates.
Tile and Slate – 100 Years
Tile and slate are considered the best roofing materials in terms of longevity. If installed by reputable residential roofing contractors, a tile or slate roof will easily outlive a generation or two living under it. In fact, this is why many historical homes still standing today have slate or tile roofs. Like with asphalt shingle roofing, maximizing its lifespan largely involves replacing damaged individual pieces as soon as possible.
