Which Type of Roofing Material Lasts the Longest?

A properly installed and maintained roof can provide security for your building for years down the road. That being said, there are a number of factors that can determine how long a roof will last, as well as a variety of roofing materials, so it can be difficult to know which type of roofing material will provide the greatest degree of longevity.

What Factors Will Impact My Roof’s Lifespan?

A roof’s lifespan is not solely dependent on the type of roofing material that it’s built from. In fact, there are a number of factors that determine how long your roof will last.

Installation

When installing a new roof or replacing an old one, it’s important to do so with high attention to detail. A poorly installed roof—regardless of the material—will have a much shorter lifespan than a roof installed with care and professionalism. It will be less energy efficient and more prone to damage and leaking. So, when your roof is installed, make sure that it’s done properly so you can get the most out of it.

Maintenance

Similarly, roofs require upkeep and maintenance throughout the year. If you don’t spend the time performing the right maintenance—like replacing missing or damaged shingles or removing tree limbs and debris—your roof will incur damages.

While most of the damage to your roof system can be repaired, leaving it to fend for itself can decrease its longevity. Instead, you should perform the necessary maintenance throughout the year to make sure that your roof lasts as long as possible. Different types of roofing materials will require different types of maintenance, too, so be sure to know what your specific type of roofing material needs before you have it installed.

Weather

Depending on where you live, your roof will be exposed to different types of weather. For example, Atlanta experiences a much higher degree of humidity year round than many other cities, so the possibility of water and moisture damage to your roof is much higher there. Moreover, different types of weather patterns—like high winds, hail, or snow—can affect various types of roofing material differently.

For instance, asphalt, tile, and wood shingles are prone to uplift from high-velocity winds, whereas metal roofs aren’t. In fact, metal roof materials are one of the best ways to combat high-velocity winds. Using knowledge of your area’s weather patterns can help you decide which type of roofing material is best for your home or business.

Types of Roofing Materials and How Long They Typically Last

Below is a list of some of the most common types of roofing materials and how long they tend to last. Of course, these are estimates and ranges based on ideal environments, installation, and maintenance.

Slate roofs: 60–150 years
Clay/Concrete roofs: 100+ years
Metal roofs: 40–70 years
Wood roofs: 30 years

Built-up roofs (BUR): 30 years
Synthetic rubber roofs: 15–25 years
Asphalt shingle roofs: 20 years
Modified bitumen roofs: 20 years

Each type of roofing material comes with its own pros and cons. For example, while slate, clay, and concrete roofs can last for more than 100 years with the proper maintenance, they’re all much heavier and more expensive than other types of roofing materials. Other types of material, like modified bitumen or synthetic rubber are preferable to use as flat roof materials, but don’t last nearly as long.

One of the most popular types of roofing materials for commercial buildings is thermoplastic polyolefin (TPO), a type of rubber roofing material. TPO is great for areas like Atlanta, where the sun is harsh, because it’s white and reflects UV rays. As a rubber roofing material, it also provides superior leak protection for all those summer storms. However, TPO can require heat welding around chimneys or other roof penetrations, so without the highest quality of installation, it can actually degrade quickly.

Metal roofs are another increasingly popular type of roofing material, and they come with a myriad of benefits as well. Not only are they one of the longest lasting types of roof, they are extremely durable and are often made with a decent percentage of recycled materials. They also require less ongoing maintenance than roofing materials like asphalt or wood shingles.

However, there are a few drawbacks to metal roofs. Although they are less expensive than slate or clay roofs, they are still one of the more expensive types of roofing material available. Moreover, due to their metallic nature, they will expand and contract with the heat and cold, respectively. In some cases, this can cause a problem with the fasteners that hold them in place. These fasteners can degrade or come loose over time, which can lead to leaks or other structural problems. Temperature changes can also cause the metal roof to warp over time.

Regardless of which type of roofing material you choose, you’ll need to make sure that it’s properly installed and maintained and that it’s conducive to the type of weather that your area experiences. Otherwise, you run the risk of limiting the quality and length of your roof’s life.
