Understanding Common Causes of Commercial Roof Damage and Maintenance Fixes

Roofs are often out of sight, out of mind — until something goes wrong. For businesses, a damaged roof can be much more than just a basic repair cost; it can also lead to lost revenue and productivity. Let’s go over the most common causes of commercial roof damage and the commercial roof maintenance strategies to keep your roof in top shape.

Thermal Shock


Thermal shock happens when there’s a sudden temperature change that makes your roof expand and contract. Think of hot summer days followed by cooler nights. Over time, this can create stress on the roof material, leading to cracks and other types of damage. One way to mitigate the effects of thermal shock is through regular inspections. Trained professionals can spot early signs of damage and recommend fixes before the situation worsens.

UV Damage

Ultraviolet rays from the sun can wreak havoc on your commercial roof. Over time, constant exposure to UV rays can cause materials to degrade, leading to a weakened roof structure. UV-reflective coatings are available that can help to deflect some of the sun’s harmful rays, prolonging the lifespan of your roof.



Leaks are perhaps the most obvious sign of roof damage and usually demand immediate attention. Water ingress can lead to electrical issues, mold, and structural damage. Often, leaks start small, so catching them early is critical. Regular inspections can help you identify problem areas before they escalate.



Pooled water is a major issue for flat commercial roofs. The weight of standing water can strain the roof, and it provides an ideal environment for mold and algae to grow. A proper drainage system is important to address this problem. Make sure that drains are clear and free of debris, especially after heavy rains or storms.



Hail can cause both visible and invisible damage to commercial roofs. While dents and punctures are obvious, hail can also weaken the material and decrease its lifespan. After a hailstorm, it’s wise to get a professional inspection to assess any damage and take appropriate action.



High levels of humidity can lead to a host of problems, including mold and mildew. Good ventilation is critical to preventing humidity-related damage. Consider installing proper ventilation systems and using dehumidifiers in problem areas.

The Importance of Commercial Roof Maintenance


There are many factors that contribute to commercial roof damage, but the good news is that most of these can be addressed with proper maintenance. Regular inspections and prompt repair work can save you a lot of trouble and money in the long run. It’s far less costly to maintain a roof than to replace one.

What to Expect From Professional Commercial Roof Maintenance


When you hire professionals for roof maintenance, you can expect a thorough inspection to identify any problem areas. They will clean the drains, check for signs of wear and tear, and make any necessary repairs. Many companies also offer preventative treatments that can extend the lifespan of your roof.
