Solar Gain began using Roof Tech’s RT E Mount AIR to install a 630-kW system at WorldMark Windsor Resort, a 10-acre vacation ownership property operated by Wyndham Worldwide Corporation in Sonoma County, California. The project has nine three-story buildings housing its timeshare units, all with asphalt shingle roofing at varying angles, which led to choosing a rail-less mounting solution.
Solar Gain’s Vice President of Commercial Operations Tim Graunke said the RT E Mount AIR’s watertight seal really helped when severe weather ran through.
“When we began the project last September, California had been in a five-year drought,” he said, “but over the following months, Sonoma County was hit with record amounts of rainfall.”
Graunke noted that previously, Solar Gain had always used flashing that slides between roof shingles. “That can sometimes compromise the integrity of the roof,” he explained, “but we did our due diligence and felt confident that Roof Tech’s butyl rubber flashing was the right way to go. We didn’t have a single leak.”
