Special Project Circumstances: A large project about two hours southeast of Milwaukee, this job needed to be completed before the start of the school year. There were multiple levels to the building with a lot of equipment to work around. The piping was painted yellow for visibility and to increase life. One roof was at complete failure and needed to be torn off and replaced.

Condition/Problem: The EPDM roof was failing due to age and weathering, causing multiple leaks throughout the field of the roof and along a wall to roof connection. Before the installation, we repaired these leaks and started the roof restoration process.

Solution: Completely swept, removed debris, and power washed the entire roof to prepare the roof for the application of the Gaco Western Silicone System. Problem areas were identified and corrected, plus all penetrations and seams were reinforced. After given the proper amount of time to cure, we then applied our primer to the field membrane. Then the Gaco S20 was applied to the entire roof. Given the necessary amount of time to cure, we returned to apply secondary touch up at areas we believed were needed.

Result: A seamless, white reflective, Energy Star rated, silicon system that will last more than 20 years.
