Meet Matthew Couvillion, Owner of Tri-21 Roofing and Construction, LLC and one of our St. George Chamber Ambassadors!

In 2017, Matt and his family welcomed their second child, Macy Joy, who was diagnosed at birth with Down Syndrome. That experience, and the support they found through organizations like Upside Downs, inspired Matt to start Tri-21 Roofing and Construction, named for Trisomy 21, the medical term for Down Syndrome.

Tri-21 is an honest, reliable roofing and construction company, and a portion of all proceeds is donated to the Down Syndrome Awareness Group of Baton Rouge and other organizations, such as The Arc of Baton Rouge, that support the special needs community. Learn more at tri21roofing.com.

Welcome to the community, Matt! 💛

Louisiana sunsets? Priceless. A roof that can actually handle Louisiana weather? Just as valuable. When you get a new roof, you want to be sure it's built to protect against everything our seasons bring.

Architectural vs. 3-tab shingles, what’s the difference, and why does it matter?

✔️ Architectural (laminated) shingles — multiple layers laminated together for a thicker, more dimensional look. Better wind resistance, better impact resistance, and longer lifespan.
✔️ 3-tab shingles — a single layer with a flat, uniform look. Lighter, less durable, and a shorter lifespan overall.

In Louisiana, where high winds and storms are part of the equation, that extra durability makes a real difference over time. That’s why architectural shingles have become our most common install by far.

Not sure what your roof currently has, or what it needs? A free inspection can tell you.
