“This roof has completely exceeded my expectations. I see other roofing systems that only last 15 or 18 years – but the roof on Robbins Hall has lasted almost twice as long.”

– Sean Snyder, Project Manager, UC Davis

ROOFING CHALLENGE: The Sika Sarnafil PVC membrane roofing system on Robbins Hall at the University of California-Davis was installed in June 1981 to house environmentally sensitive teaching laboratories. In 2015, DC Consulting Services took two core samples from the roof after it was determined that it was acceptable for heat welding. The new patching membrane fully adhered to the 34-year-old membrane. “It is performing as well as some of the newer roofs on campus,” Snyder said.
