Building Stronger Roofing Companies, Together
G1 Group is a Lancaster, PA-based holdings company that acquires and supports roofing businesses with centralized shared services — so each company can focus on what it does best.
Who We Are
G1 Group is a holdings company that acquires and operates roofing businesses across multiple states. Headquartered in Lancaster, Pennsylvania, we provide our portfolio companies with the back-office infrastructure, technology, and strategic support they need to grow — without losing the local identity and relationships that made them successful in the first place.
The Shared Services Model
Instead of every company building its own back office from scratch, G1 Group centralizes key functions across the portfolio. This eliminates redundancies, strengthens capabilities, and lets each company benefit from group-level resources and expertise.
The result: centralized shared accounting, standardized financial visibility, group-level vendor pricing, and a unified technology platform — turning fragmented operations into a competitive advantage.
