Contractor: Commercial Roof Management

Job location: Irvine, California

Original roof assembly:

EPDM, age unknown. The roof surface was pin holing throughout and had over 100 roof leaks in 124,000 square feet, (1,240 squares).

Selection of Western Colloid:

Originally the building owners thought that their only option was to tear off the EPDM and replace with a similar product.  They hired a roof consultant who recommended Western Colloid’s Fluid Applied Reinforced Roofing as a solution.

Western Colloid has systems that are fully tested and approved by FM for overlay installation over EPDM.

Western Colloid presented a specification that would eliminate the removal of the existing roof assemblies and save 30 – 40 % on the overall project costs by not removing the old roof and saved man-hours on the installation.  Additionally future savings will be enjoyed with their now energy efficient white roof.

Pacific Dental avoided the disruption to their employees by a lengthily roof removal and re-installation plus the debris and landfill waste was at a minimum.

The Western Colloid specification allowed the contractor to use a temporary fix to stop the leaks with #800 Elastic Cement and polyester reinforcement.  Then continuing with this extra layer of protection in the waterways and drains.

Final installation steps included #298 asphalt emulsion with polyester reinforcement.  Once cured, the system was surfaced with Western Colloid’s ElastaHyde acrylic coating.
