Original roof assembly:
The original roof was a built-up roofing system, later top-coated with a white acrylic.
As a working hospital, the building owners had to choose a system that would have no impact on the operation of business or on the comfort and safety of the patients. Their entire roof was failing and the top coat designed to extend its life was peeling in a manner referred to as “potato chipping.”
Selection of Western Colloid
Western Colloid was the ideal choice for this project because they offer products that have no hazardous fumes, which is key for any roof being installed on an occupied building. Choosing Western Colloid eliminated the need for tear-off and removal of hazardous waste, which is especially sensitive in a hospital setting. Western Colloid was able to offer a solution that kept the existing roof in its place without removal. Lastly, this method offered savings of over 30% on the cost of the roof restoration versus a replacement, delivered the added value of an energy efficient roof and included an industry-leading warranty.
The existing substrate was prepared by removing the peeling coating and cleaning the roof surface. After addressing drains, seams and protrusions, a light coat of emulsion was used to fill the void. JBS Roofing then installed a Western Colloid Fluid Applied Reinforced Roof System consisting of a 1-Ply Polyester Reinforced and embedded Acrylic Surface.
