Leaky and Aging HVAC Portal Causing Roof Leaks on a Commercial Flat Roof in Chicago

Aging HVAC portals are a common source of roof leaks in commercial buildings, especially when the original installation was not properly sealed or has deteriorated over time. On this Chicago commercial flat roof, our inspection revealed that an old and leaky HVAC portal was allowing water to seep into the roof system, leading to moisture intrusion and potential damage to the interior structure.

At Anchor Point Roofing, our commercial roofing team is addressing this issue by removing the existing HVAC portal and installing a properly fabricated metal pitch pan around the HVAC line set. This ensures that the penetration is securely sealed and can accommodate any movement or vibration from the unit itself.

To complete the repair, we’ll apply Lucas 6000, a high-performance sealant designed for long-lasting waterproof protection on flat roofing systems. This final step helps create a watertight barrier that prevents future leaks and extends the roof’s service life.

Whether it’s a leaky HVAC portal, aging membrane, or other commercial flat roof concern, Anchor Point Roofing provides reliable repair and maintenance solutions throughout Chicago. Our goal is to help property owners protect their investment with durable, high-quality roofing work that stands up to the city’s demanding weather conditions.
