To provide a 40,000-square-foot roofing system that could be applied without removing existing roof assembly.
After preparation and installation of Kemperol membrane at perimeter, base flashing provided a monolithic edge-to-edge application over existing asphalt roof. Application eliminated exposure to weather conditions in the critical lab area below the structural deck.
Owners required a roof membrane to cover a series of high-profile buildings, which eliminated the need for costly and difficult removal of 100,000 square feet of existing roof assembly.
Installation of a full edge-to-edge Kemperol membrane over existing roofs provided a practical, cost-effective alternative for a long-term warranty.
Recover two existing layers of asphaltic built-up roofing installed over a steel deck. Difficult access made removal and replacement prohibitively expensive, and would have disrupted operation of this prestigious upscale hotel during prime season. Existing roofing had some areas of moist insulation. Owners wanted a cost-effective solution that would not effect hotel operation.
Install Kemperol roofing system and Kemperdur colored aggregate surfacing. Compact packaging of Kemper System materials made access to working areas straightforward. Disruption of hotel operation was avoided due to the clean and quiet characteristics of Kemperol system installation. Application proceeded quickly, saving weeks compared to traditional roofing practices, and the Owners were provided with the cost-effective solution they desired.
Existing roof had moisture in Perlite insulation board assemblies in valuable warehouse structure. Needed to add waterproofing membrane without removing existing roof system, as conduits over the surfaces made removal next to impossible.
Due to its permeability Kemperol V210 membrane was installed, eliminating the demolition phase of the project and thereby reducing costs. In addition, phasing of the project became practical. The application, the oldest Kemper installation in the United States, has performed without failure since 1982.
