Sunlight Degradation on Commercial Roofs

By in

It’s summertime in Omaha, and the sun is pounding commercial roofs with UV light like it does every year. The sun’s ultraviolet (UV) light is notorious for degrading roofs over time. As chemicals in modified bitumen, shingle, metal, or single-ply roofing membranes are continually exposed to UV radiation, the materials break-down and degrade. Even in Omaha, the sun will have a major impact on the longevity of your commercial roof. In this article, we’re going to take a closer look at sunlight degradation does to your commercial roof, and some possible solutions to get more life out of your roof, along with some other bonuses that come with choosing a cool roof solution.

The Effects of the Sun on Your Commercial Roof

Unfortunately, there is no such thing as a sun-proof roof. As the sun heats up your roofing materials, it causes them to expand, and as they cool, they contract. As this expanding and contracting cycle continues every day, it weakens and degrades your roof materials. Thanks to new white reflective roof technology, you can mitigate the sunlight degradation to a great extent. More on that later.

Types of Damage Your Roof May Experience from the Sun

  • Blisters – Bubbles of hot expanding air
  • Bleaching – Discoloration of roofing material
  • Warping – Structural problems that require immediate attention
  • Cracks – Can be the source of roof leaks if not properly repaired

The Effects of the Sun on a Black Commercial Roof

Black roofing materials absorb the sun’s UV rays and heat up fast and stay hot for long periods. This shortens the lifespan of the roofing materials and expedites the breakdown process. Other damages like cracking or blistering are also common on black commercial roofs. A darker roof will not only break down faster but also increase your building’s energy costs.

Reducing Sunlight Degradation with a Cool Roof

Cool Roofs are white and have been designed to reflect sunlight and absorb less heat. A cool roof will reflect the sun’s UV rays and does a much better job of resisting sun damage compared to black roofs. As a bonus, cool roofs help control your building’s energy costs by keeping our building cooler. Long-term, white reflective, cool roofs, have proven to last longer than black roofs, and are the same cost or substantially lower depending on the system.

For example, you may have an older black roof that needs to be repaired or replaced. With today’s commercial roofing system technology, we can convert your old black roof into an energy-efficient cool roof with a spray system. These systems are watertight, very affordable, and can be renewed indefinitely.
