What might indicate that a roof membrane performance is compromised?

Visible discoloration and water stains indoors can be clear indicators that a roof membrane’s performance is compromised. When there are water stains or discoloration on ceilings or walls, this typically suggests that there is a failure in the roofing system, allowing moisture to penetrate. This moisture can lead to further issues, such as mold growth and structural damage, which not only affect the integrity of the building but also suggest that the waterproofing capabilities of the roof membrane are failing.

Increased energy costs can be a symptom of several issues, including HVAC inefficiencies or poor insulation, but they are not as direct an indicator of a roof membrane's failure as visible signs of water intrusion. The presence of UV-resistant coating, while potentially helpful in prolonging the lifespan of a roofing system, does not by itself indicate whether the membrane is performing properly. Similarly, the absence of debris on the roof surface might suggest maintenance care, but it does not necessarily correlate to the membrane's effectiveness in preventing leaks or damage.
