Two brothers. One commercial focus. A firm built to last.

Ben and Brandon Terhune didn't stumble into commercial roofing. They came to it with existing experience in the trade and a clear picture of where they wanted to operate: larger commercial buildings, government facilities, and institutional clients who require documentation, certification, and a contractor who understands the procurement side of the business.

Starting a firm isn't a shortcut — it's a decision to build the right platform. Centennial Shield was structured from the start to qualify for the SDVOSB set-aside program, to carry manufacturer certifications that commercial buyers and government contracting officers actually check, and to operate with the documentation discipline that separates a contractor from a crew.

They're based in Amarillo because that's their market. The Texas Panhandle has a large inventory of aging commercial flat roofs, a significant federal facility presence — including the Thomas E. Creek VA Medical Center and the broader Pantex contractor ecosystem — and a shortage of certified, locally-rooted SDVOSB roofing contractors. That's the gap Centennial Shield is built to fill.

Commercial roofing buyers — facility managers, procurement officers, building owners — generally know what a bad contractor experience looks like: a salesperson, a vague scope, and a substandard installation that starts failing two years after the check cleared. The Panhandle has a long memory for that pattern, particularly after every major hail event when out-of-state crews flood the market.

We approach projects the other direction. An inspection comes before a proposal. The proposal cites the spec — system type, FM uplift rating, manufacturer, warranty tier. Bids for government work include the documentation the contracting officer needs to evaluate them: certifications, insurance, SDVOSB status, references. Everything is in writing because the closeout package is how the next maintenance cycle knows what was installed.

That discipline reflects the kind of clients we're building for: government facilities managers, institutional building owners, and commercial operators who will be back in five years when the warranty period matters. We're not chasing storm volume. We're building a track record that compounds.

Centennial Shield serves commercial clients within a 200-mile radius of Amarillo. That reaches the full Panhandle — Canyon, Pampa, Borger, Dumas, Hereford, and the South Plains communities south toward Lubbock. It also includes the federal facilities in and around Amarillo that are closest to home.

For commercial buyers, that footprint means a contractor who can respond quickly, pull permits locally, and service a warranty without a travel surcharge. For government procurement officers, it means a contractor who is present in the market — not a firm bidding from Houston on a project they'll staff with subcontractors they've never used.
