Roof Design: How Long Will It Last?

A lot of people wonder how long a roof is designed to last. The longevity depends on various factors, including the type of roof, the climate, the quality of material used, and if the roof undergoes regular maintenance.

How Long Does A Roof Last?

The average asphalt roof will last 20-30year. Although this isn’t the same everywhere, some may last longer, some a lot shorter. It all depends on how regularly you have it inspected and serviced.

What Factors Affect The Lifespan Of A Roof?

Earlier, we mentioned that various factors could influence the longevity of a roof. Below are some of the important ones to bear in mind:

Type Of Roof

The kind of roof you choose does make a big difference in how long your roof will last. Take, for instance, asphalt shingle roofs. These roofs usually last 20 to 3 years, while metal roofs are designed to last 50 years and sometimes more.

Quality Of Materials

The quality of the materials your roof is made from is also a big factor in how long your roof will last. Using Asphalt shingles as an example, they are a lot cheaper than metal roofs but less durable.


It would help to consider your area when choosing a roof. If your area is more prone to adverse weather, e.g., storms or hurricanes, your roof would probably suffer more wear and tear compared to a roof in a milder climate.


If your roof is installed by a professional roofing company that prioritizes delivering quality roofing services, your roof will take a while longer. But if installed by a low-quality roofing company, chances are that your roof will start to develop issues before its set time.

Life Expectancy Of Different Roofs


Asphalt Shingles

These are the most common roofing materials. They are cost-effective and long-lasting and come with warranties of up to 25 years. Asphalt shingles protect from extreme elements, such as snow, wind, rain, and strong UV rays. You can expect your asphalt roof to last between 15 and 30 years.

Metal Roof

Metal roofs have a long life span. They can last anywhere from 40 to 70 years, depending on the metal, design of the roof, and installation method used. Using a roof made from high-quality metals like copper and zinc can last for at least a century!

Slate Tile Roofs

These roofs are known for their exceptionally long lifespan, ranging from 75 to hundred years. Manufacturers of slate tiles offer warranties of up to 75 years. Slate tiles can withstand weather conditions, such as strong winds, and don’t require much upkeep.

The best way to preserve your roof and extend its lifespan is by performing routine maintenance regularly. This way, you can make sure your roof is in good condition.
