Approach

After meetings with the insurance carrier’s team of adjusters, roofing contractor and engineers, CIMA conducted additional forensics work demonstrating that the original hail claim was valid. In addition, they found that there had been recent hail damage from another storm which led to the recurring roof leaks. Based on this new evidence, the insurance company reversed the denied claim and approved the restoration of the property back to its pre-storm condition.

Roofing system

CMS’ existing roof assembly was comprised of a 22-inch intermediate-rib steel deck that supported two roofing systems: a built-up and mechanically fastened 60 mil PVC single-ply membrane, topped with a sprayed-on coating. Although TPO/PVC systems are proven roofing systems for different types of commercial buildings and circumstances, the system did not meet either manufacturer or industry standard practices for this particular building design and composition. Upon CIMA’s recommendation, therefore, CMS chose to install a completely different high-performance roof system—one that would provide greater energy-efficiency, better tolerate building movements, and be highly resistant to wind-driven rain, foot traffic and falling objects.

Implementation

CIMA removed the two existing roof systems and installed CertainTeed’s FlintBoard® ISO insulation, which was mechanically attached to the structure’s steel deck. The goal was three-fold: to meet local city building code requirements; substantially reduce heat buildup inside the building during the summer months; and maintain warmer temperatures during the winter months. CIMA also sought to eliminate areas prone to water ponding, which occurs when there is an inadequate slope along the corners of the roof and upper-level sections, by installing a tapered FlintBoard® ISO-T insulation that would reconfigure the cricket geometry and sumps in the roof’s corners and redirect water run-off to the new drainage system. CIMA then applied CertainTeed’s self-adhering Black Diamond® Base Sheet, which is highly valued for its strength, dryness protection and ease of handling, while also providing additional protection against wind-driven rain. Finally, a torch-applied layer of CertainTeed’s Flintlastic® GTA cap sheet was added to provide a superior interplay bond strength, along with additional puncture and tear resistance. Together, these membranes would have a total thickness of 220 mil—rather than the old 60 mil—providing a higher degree of re-enforcement and protection.

Results

After years of torment, CMS was gratified that with CIMA’s help, they had finally resolved their leak problems. Now, they had a brand-new roof that would provide a dry environment and greater comfort for employees year-round. With that peace of mind, the company was able to confidently expand inventory and continue to grow their business. As with all its jobs, CIMA provided a 15-year NDL warranty for this project, guaranteeing its work for CMS well into the future.
