How Long Does a Flat Roof Last?
Posted on April 27, 2023 by Phillip Camerer
For businesses, receiving the best result from their investment is critical. That’s why the question “How long does a flat roof last?” is asked quite often. Overall, a flat roof can last anywhere from 15 to 30 years. The wide range of years is due to the various factors that can affect a roof, such as:
- Type of roof coating
- Frequency of roof maintenance and cleaning
- Extreme climate conditions
All of these factors can create situations that are detrimental or favorable to the lifespan of a flat roof. However, your roof will start showing signs of aging, such as ponding water, leaks, cracks, and discoloration, regardless of the type of roof coating.
What is Roof Coating?
Roof coatings can provide a layer of extra protection, extending the life of a flat roof. A roof coating is formulated to be highly elastic while remaining adhered to the roofing materials.
That allows them to protect a roof from harsh environmental conditions, including UV light, excessive moisture, and wind damage. Not only does it save a roof for many years, but roof coatings can also get reapplied to preserve a roof’s lifespan further.
There are several types of roofing coatings, which you can read about in our blog: Different Styles of Protective Roof Coatings and Their Benefits.
Compared to replacing a roof, roof coating installations are typically cheaper, less intrusive, and have a shorter time frame. That means most businesses can operate like normal with little to no disruptions.
Phillip Camerer Roofing works with facility managers as much as possible to help protect their commercial buildings without needing to shut down.
How Often Should a Flat Roof Be Coated?
Another common question about flat roof coatings is how often should a flat roof get coated. A flat roof can take quite a beating from the elements like sun exposure, snow and ice accumulation, and be damaged from heavy wind gusts.
That can lower the life expectancy of an unmaintained flat roof to around 10 years. Home and business owners can easily extend their roofing investment with regular maintenance, including recoating.
Roofing professionals often recommend applying a fresh coat every 2 – 4 years to safeguard the integrity and performance of a roof. However, the exact timing for a new roof coating depends on the conditions your roof gets exposed to. If you are concerned about the state of your roof or would like an inspection after a storm, contact Phillip Camerer Roofing.
Important Note: Spring weather changes can make schedules for a roof coating difficult. Excessive moisture and high or low temperatures create issues with roof coating cure times and product quality.
Will Elastomeric Roof Coating Stop Leaks?
One of the most significant benefits of elastomeric roof coating is moisture-proof protection. The waterproof roof coating formula works to seal off water from seeping into any cracks forming on the roof surface.
Depending on the extent of damage, some roofing materials may need to get replaced before applying an elastomeric roof coating. Leaks are notoriously difficult to track back to their source, and any repairs should get left to the professionals. Your local roofing contractor will inspect and advise on the proper repair steps for a flat roof leak.
