Sunset District Office Building Transforms Operations with TPO Installation

Michael Zhang stared at his utility bills in disbelief. His three-story office building on Irving Street was hemorrhaging money, $2,400 a month just in cooling costs during summer. Tenants complained constantly about temperature fluctuations. His 20-year-old built-up roof was cracked, leaking, and turning his building into an energy disaster.

“I was losing tenants because of the heat,” Michael explained. “The top floor was unbearable from May through October. I needed a solution that would actually work, not just another patch job.”

We proposed a complete TPO roofing system with a bright white, heat-reflective surface designed for San Francisco’s climate. Michael was skeptical. “Will it really make that big a difference?” he asked.

We didn’t just promise, we showed him thermal imaging, energy calculations, and references from three other Sunset District commercial properties we had completed. He was convinced.

Our crew worked section by section to avoid disrupting tenants. We removed the old failing roof, installed new commercial-grade insulation, and laid down a seamless TPO membrane that turned the building into a cost-saving asset.

The results were immediate and dramatic. Michael’s first summer cooling bill dropped from $2,400 to $1,380, a 42% reduction. Top-floor temperatures stabilized. Tenant complaints stopped. When the building inspector reviewed the installation, he called it “textbook perfect.”

“I’m not exaggerating when I say this roof paid for itself in three years,” Michael shared recently. “Best business decision I’ve made. My tenants are happy, my bills are down, and I haven’t had a single leak in five years.”

That’s commercial roofing done right. Royal Roofing CA delivers solutions that make financial sense, not just roofing sense.
