The lifespan of a roof depends on a multitude of factors and can vary drastically on a case-by-case basis.
There are, nevertheless, a few overall trends that can help you get a grip on the rough lifespan of your roof. By focusing on a few key factors, you’ll be able to help your roof last as long as possible.
Let’s go through some of the options for extending the lifespan of your roof.
Assessing the Life of Roofing Materials
Generally, shingle roof installation consists of shingles made of asphalt, cedar and metal, with each having its own individual life span. Asphalt shingles typically have a lifespan of up to 20 years, while cedar roofs can last from 25 to 40 years and metal roofs from 40 to 70 years.
Additionally, the slope and type of roof also play an important role in lifespan as roofs that sit lower, or have more valleys and ridges, will naturally weather and deteriorate more quickly than those that are less exposed.
Average Lifespan Estimates by Roof Type
On average, the lifespan of a roof depends greatly on the type of material used in its construction. Concrete and clay tile roofs have an estimated lifespan of 50 years or more. Asphalt shingles are typically good for 25 to 30 years, while metal roofs may last 40 to 70 years.
Maintenance to Extend Your Roof’s Life
Maintaining a roof is an important part of preserving the value of a building. An investment in proper roof maintenance can extend the life of the roof well beyond its original lifetime.
The average lifespan of a roof can be extended with good maintenance practices. An asphalt roof will last an average of 20-30 years, but with regular maintenance and inspections, that lifespan can be extended to 40-50 years.
Factors Contribute to Roof Longevity
The average lifespan of a roof depends on a variety of factors, with the most important being the type of roof, the materials used, and the climate. Generally, roofs made with concrete can last up to 50 years, while an asphalt shingle typically lasts 20 to 25 years.
Longer roof life span is affected by the quality of installing roof materials used, the level of maintenance, and the atmosphere. For example, in hotter climates with high UV exposure, such as those in the south, roofs tend to have a shorter life expectancy because the increased heat can cause the material to break down more quickly.
Impact of Weather on Roof Lifespan
Hot climates, extreme temperatures, and intense wind and rain can all decrease a roof’s lifespan. In addition, heavy snow and hail can cause extra stress on the roof, leading to repairs and shortened lifespans.
Additionally, it is wise to inspect the roof periodically to look for signs of damage and to stay proactive in repairing any issues as soon as they appear. If a major weather event is impending, it is important to take extra measures to protect the roof and seal any openings to prevent damage.
