When looking at your roofing as it gets older you may wonder how much life is still in there. The main factor determining roofing lifespan is the material it is made of. Here is a short list of some popular roofing materials and how long you can expect them to last before needing replacing.
- Asphalt Shingles: The lifespan of asphalt shingle also depends on the quality, but generally they can last 15-30 years. Cheaper singles will tend toward the lower of that range, while better quality shingles will tend toward the upper end of the range.
- Wood: Wood roofing can last up to 30 years, but with some variance with specific type of wood and location. However, 30 years is the average, assuming regular maintenance and upkeep is done.
- Metal: Metal roofing is one of the longest lasting roofing materials but is also very expensive. However, it may pay off when it can last 70 years. Some types of metal, like zinc or copper, might even last up to 100 years!
- Slate: While slate is very expensive and may require reinforcements in your home to hold up the weight, it can last an incredibly long time. Soft slate can last from 50 to 125 years depending on conditions, but hard slate is able to last 75 to 200 years. This material is incredibly strong and durable and will probably outlive you!
When looking at the lifespan of a roof it is important to know exactly what material it is, as well as what it has been through. These numbers are not exact, but they can help you estimate how long your roof will last.
