Industrial roofs—whether atop warehouses, factories, or storage facilities—are constantly exposed to the elements. Among these, ultraviolet (UV) radiation is a particularly insidious threat. At Unitech SA, we understand that even slight roof deterioration can lead to significant long-term problems. In this article, we explain how UV exposure affects industrial roofing and why regular maintenance is critical.

The Effects of UV Exposure
Polymer Degradation
UV rays break down the polymers used in roofing materials such as EPDM, PVC, and TPO. This degradation results in a loss of flexibility and elasticity, weakening the overall structure of your roof.
Cracking and Brittleness
As UV exposure continues, the roofing material becomes increasingly brittle. This brittleness makes the roof prone to cracking, creating opportunities for water penetration. Once water infiltrates the structure, the damage can escalate rapidly, leading to costly repairs.
Discoloration and Chalking
Over time, UV radiation causes the roof’s surface to discolor and chalk. This not only affects the roof’s aesthetic appeal but also reduces its reflectivity, leading to increased heat gain and potential overheating of the building.
Membrane Deterioration
The integrity of roofing membranes is compromised under prolonged UV exposure. The gradual deterioration can eventually cause a loss of waterproofing, significantly raising the risk of leaks and internal damage.

The Importance of Regular Maintenance
Timely Inspections
Regular inspections are essential. A professional evaluation can detect early signs of UV-related damage before they develop into major issues. Early intervention means less disruption to your operations and lower repair costs over time.
Preventative Measures
By scheduling routine maintenance, you can extend the life of your roofing materials. This proactive approach not only preserves the quality of your roof but also safeguards your investment in the long run.
