About Green Group Roofing
Certified roofing specialists serving the San Francisco Bay Area with manufacturer-backed quality.
Our Story
Green Group Roofing was founded with a simple philosophy: specialize in one trade and master it completely. While many contractors spread their expertise across multiple home improvement services, we made the deliberate choice to focus exclusively on roofing.
This specialization has allowed us to build deep partnerships with the industry's leading manufacturers—GAF and Owens Corning—and to train our crews to the highest standards. We're not general contractors who occasionally install roofs. We're roofing specialists who live and breathe this trade every single day.
Why GAF and Owens Corning?
We chose to partner with GAF and Owens Corning because they represent the gold standard in shingle manufacturing. Their systems aren't just individual products—they're complete roofing solutions engineered to work together seamlessly.
When we install a GAF or Owens Corning system according to their specifications, homeowners gain access to enhanced manufacturer backed warranties that provide far greater protection than a standard contractor guarantee.
This partnership benefits you directly: superior materials, better warranty coverage, and the peace of mind that comes from knowing your roof is installed by factory-trained professionals who understand these systems inside and out.
