Timberhill Villa, San Antonio, TX
Background
The owners of Timberhill Villa sought out a well-respected roofing contractor that they believed could manage the job smoothly and professionally. CIMA Contractors LLC, specializing in storm damage restoration projects, impressed ownership with their expertise on a nearby project and were hired to perform the job at Timberhill Villa and collaborate with the retirement community’s insurance carrier throughout the process.
Approach
At 29,000 square feet and four stories, with three separate roof areas supporting HVAC and gas lines the retirement center’s replacement project was no small undertaking. CIMA and CertainTeed created a roof system not only to meet the performance characteristics of the building but to also ensure the least amount of noise to the residents during the installation process.
Tear-off consisted of removing the existing built-up roof system in order to perform a clean deck installation. The substrate is a heavy weight concrete deck providing the foundation to which a hot mopped fiberboard was applied as opposed to a mechanically fastened application that would have been very noisy and disruptive to the residents.
Crickets (tapered insulation system) were designed and installed to ensure positive drainage to the scuppers and prohibit water ponding. Next, a CertainTeed self-adhering Black Diamond® Base Sheet providing additional strength and moisture resistance was installed. This was followed by a torch applied
Flintlastic® GTA for high performance puncture and tear resistance. The roof system was approved for a 15-year No Dollar Limit manufacturer’s warranty provided by CIMA.
Results
With a 15-year NDL warranty, the retirement community not only attained a quality new roof, but the peace-of-mind that would help them focus on its mission of helping elders rather than worrying about the integrity of their facility’s structure. With the elimination of ponding, and the leakages and maintenance headaches it caused, the Timberhill Villa team was confident that the building’s roof would be trouble-free for years to come.
