When people think of commercial roofing damage, high winds usually come to mind first. Yet ultraviolet (UV) rays can also cause problems, especially in Arizona where the sun is shining most days of the year. Here, learn what sunlight can do to your business’s roofing system and what steps you can take to preserve your investment.

Problems Caused by UV Rays

Certain roofing materials, such as bitumen, tend to absorb heat from the sun. This can raise the temperature of your building, and therefore, your air conditioning costs. The dry, unforgiving heat can also turn sealants and the roofing membrane brittle, making it more prone to cracks and leaks. Cracks enlarge in response to chilly nighttime temperatures, resulting in loosened roofing materials.

As the roof weakens from UV damage and age, the structure can start to sag and compromise the safety of those inside the building. Flat roofs are also prone to blistering due to gas buildup inside the roofing membrane since gas tends to expand with heat. 

Prevention & Treatment

Protect your commercial roofing system from sun damage by scheduling annual professional inspections. Experts will uncover any issues so they can be repaired immediately before precipitation or pests can take advantage of the weakness. 

You should also have them check that your roof has proper ventilation since this stops heat from building up and causing cracks, blisters, and other damages. Additionally, they can apply protective coatings to your flat roof membrane to help your building better reflect, rather than absorb, the light from the sun. There are several options from simple white elastomeric coating, re-new coating systems to poly urethane insulating new membrane applications. A professional can fully explain and demonstrate all of your options.
