Hirschi Roofing and Insulation runs out of an office on North 1800 East in St. George, and pairs two trades that usually live in different shops under one phone number — (435) 673-6667. Roofing and insulation are the kind of work most contractors split apart and subcontract; Hirschi keeps both in-house. The Hirschi surname is in the brand but no public surface ties it to a specific person, which is unusual for a company old enough to have built up the supplier relationships it has.
A twenty-mile circle that matters
The service area is stated as roughly a twenty-mile radius of the office, with explicit reach to Mesquite, Cedar City, and the rest of Washington County. That circle is the practical Southern Utah residential market — Hurricane and La Verkin to the east, Ivins and Santa Clara to the west, Mesquite over the Nevada line, Cedar City when the schedule allows the drive up I-15. A roofer who works that circle every week ends up doing the same kinds of jobs over and over: the 1990s and 2000s tract homes whose original shingles are aging out at the same time the original attic insulation is finally giving up.
Why one shop for both trades
The roof-and-insulation pairing is the practical answer to a Southern Utah envelope problem. The desert pushes attic temperatures well past what builder-grade insulation was specified for, and the same roofs that need replacement after twenty years of UV exposure usually need an insulation upgrade alongside them. A homeowner who does not want to coordinate two crews — and does not want to pay one contractor to wait on another — tends to find Hirschi through that exact need.
Material partnerships, not marketing
The supplier list is the giveaway on what Hirschi actually does day to day: GAF, CertainTeed, Eagle Roofing tiles, Roofers Supply. Those are the conventional residential systems on most Washington County houses built in the last thirty years. The web presence is utilitarian — clear phone, clear address, clear service area, no aggressive sales overlay — which fits a contractor whose work comes from referrals and supplier relationships rather than paid search.
For a 435 register, Hirschi is a stable, locally fixed trades operation with a defined service radius and the kind of supplier stack that signals real volume. The missing public ownership detail is the only meaningful gap.
