Rio Roofing

Nathanael and Sam Zúñiga met in high school and married in 2012. Their own About page tells that part plainly. Some time after that they started Rio Roofing — the founding year of the business itself isn’t posted publicly, which is one of the few pieces of the story they leave on the table. The yard is at 236 Stonehedge Drive in Washington, the small grid town just east of St. George that has spent the last fifteen years quietly absorbing the runoff of Washington County’s growth without ever quite becoming St. George.

A husband-and-wife trade business

Nathanael came in from a construction background after engineering degrees; Sam handles operations and the customer side out of a business management background. That split — one principal on the trade, one running the office — is the structural shape of a working family roofing business, and it shows in how the company presents itself. The website is plain, the photos are of actual jobs, the testimonials wall is populated with first names from Washington County. They are members of the Southern Utah Home Builders Association, which is a useful third-party anchor: SUHBA is where the actually-working trades in the region cluster, and the dues are real.

Two phone lines, two counties

Rio covers the full footprint a 435 register cares about: St. George, Washington, Santa Clara, Ivins, Hurricane, La Verkin, Toquerville, and up to Cedar City, where they keep a separate line at 435-319-0022 and a dedicated landing page. Materials run the normal Southern Utah mix — asphalt shingle, concrete tile, standing-seam metal, and TPO for the small-commercial flat-roof side — plus repairs and free inspections, which is the table-stakes offer in this market.

One thing worth flagging. The Cedar City service page lists a license number formatted as “ROC 362572,” which is Arizona Registrar of Contractors syntax, not Utah DOPL syntax. That might mean Rio also pulls Arizona work; might be a website error. Either way, the Utah DOPL number is not displayed, and that’s a question for the owners rather than something to claim from the public web.

Rio is the version of the trade that’s still small enough to have the owners on the phone and big enough to pull permits and run a real crew across two counties. For the 435, that’s a useful spot in the field — between the multi-state shops with marketing departments and the one-truck operations that disappear after a busy summer. Rio is what the trade looked like before the rollups showed up.
