Project Profile: STERIGENICS – Charlotte, NC 65,549 sf
This TPO roofing project improved roof performance and extended the service life of the building’s flat TPO roof.
Sterigenics was facing the typical problem facilities have when their roofs are 25 years old, leaks. A lot of the flashing around the HVAC units and skylights had deteriorated and was letting water underneath the membrane. After inspecting the existing insulation, we determined not all the insulation was damaged or wet so we were able to salvage most of it, reducing the overall cost of the project. A detailed inspection helped define the best scope for this TPO roofing project. It also showed where the existing flat TPO roof could be preserved. That reduced waste and helped control replacement costs.
They were happy with the previous TPO roof system’s chemical resistance, reflectivity and durability so we specified a mechanically attached re-cover with GAF’s 60-mil TPO membrane. We tore off all 65,549 square feet of the existing membrane and replaced the wet insulation as needed. Since there is a lot of foot traffic on the roof we installed walkpads at all the HVAC units for added durability. TPO roofing remained the best fit for this facility’s flat roof needs. The new TPO roof system offered durability, reflectivity, and solid long-term value. A mechanically attached TPO roof can also perform well on large commercial buildings.
All the parapet walls, scuppers, curbs and penetrations were re-flashed and Sterigenics got a brand new TPO re-roof. GAF Inspectors rated this roof system a perfect 10 on their visit, and we were able to give them a 20 year warranty. This completed TPO roofing project gave the owner a durable flat TPO roof with updated flashing details. It also improved confidence in long-term TPO roof performance. The 20-year warranty added another layer of value.
