Project Capsule: On a busy multi-tenant commercial property in Grand Junction, Colorado, CRC replaced an aging, leak-prone metal roof with a fully-adhered Johns Manville TPO membrane recover system, first locating hidden leak points with drone thermal imaging, then coordinating a multi-day rebuild that kept every tenant operating without interruption.
Project Facts
| Location | Grand Junction, Colorado |
| CRC office | Grand Junction Office |
| Building type | Multi-tenant commercial property |
| Method | Full membrane recover over the existing metal roof, no tear-off |
| Roof system installed | Johns Manville 60-mil white TPO membrane, fully adhered over rigid polyiso insulation and a coverboard |
| Leak detection | Drone thermal imaging scan of the roof performed before the recover |
| Manufacturer | Johns Manville, installed by a JM Peak Advantage certified contractor |
The Challenge
The building is a busy multi-tenant commercial property in Grand Junction with an aging, ribbed metal roof. Years of high-altitude UV, snow, and temperature swings had left the panels and their seams and fasteners vulnerable, and the property needed a fix that would not force tenants out or interrupt their operations during construction. Before any work began, CRC ran a drone thermal imaging scan of the roof to find exactly where heat and moisture were escaping through the metal, rather than guessing at problem areas from the ground. The scan pinpointed leak points at seams, fasteners, and penetrations across the field, giving the project team a precise map of what the new roof system needed to solve.
The Solution
Instead of tearing the metal roof off, CRC recovered it with a new low-slope membrane system built directly over the existing panels. FluteFill filled the metal ribs to create a flat plane, rigid polyiso insulation went down over that, a coverboard was mechanically fastened on top, and a Johns Manville 60-mil white TPO membrane was fully adhered across the entire roof.
The roof system was only half the job. Keeping the property fully operational during a major commercial reroof took hours of hands-on coordination from the CRC project manager, including scheduling two large material deliveries in the same window, mapping site logistics so trucks and equipment never blocked tenant access, and sequencing the crew around a tenant whose operations had to keep running throughout the project. One tenant space was covered floor to ceiling in protective sheeting to keep it fully shielded and usable while the roof overhead was rebuilt. Across the job, a single point of contact managed the property owner, the on-site team, the installation crew, material deliveries, and scheduling in real time.
The Result
The building went from an aging, leak-prone metal roof to a seamless white TPO membrane system engineered for the Grand Valley's sun, snow, and temperature swings. The reflective white surface lowers cooling load, the fully-adhered membrane seals the leak points the thermal scan identified, and the recover approach delivered a new roof without the disruption of a full tear-off. The project also shows the level of coordination CRC brings to a complex commercial job: a fully operational, multi-tenant property throughout construction, with every tenant able to keep running their business.
