Your roof is only as good as what it's made of and who installs it. That's why we build with GAF Timberline HDZ® shingles, the best-selling shingle line in North America.
Learn About GAF's History →Most asphalt shingles are simply glued in layers. Timberline HDZ shingles mechanically fasten their layers together, creating a stronger bond across your entire roof — and unlocking GAF's strongest wind protection.
When we install the complete GAF system with its required accessories, your roof qualifies for the industry's first wind warranty with no maximum wind speed limit — serious peace of mind in Missouri storm country.
Time-release algae-fighting technology defends against the ugly blue-green streaks common on Midwest roofs, backed by a 25-year StainGuard Plus™ limited warranty.
Every roof we install comes with two layers of protection, and we'll walk you through both before work begins:
We install two of the most trusted names in siding: CertainTeed vinyl and James Hardie fiber cement. Here's how to think about your options — and we'll walk you through them in person, no pressure.
All three CertainTeed lines carry lifetime fade protection and limited lifetime warranties. The main difference is panel thickness, which affects rigidity, appearance over time, and price:
CertainTeed's entry-level panel (.040" thick). A budget-friendly way to get a clean, low-maintenance exterior with plenty of color choices. Best for tighter budgets and rental properties.
The mid-grade workhorse (.042" thick) with multiple profiles and around 25 colors. A solid step up in stiffness and appearance without the premium price — the right fit for most St. Louis homes.
CertainTeed's premium line (.046" thick) — the thickest, straightest-hanging panel with rich cedar texture and the widest color selection. Engineered for high wind resistance and the best long-term curb appeal.
For homeowners who want the most durable siding made, we install James Hardie fiber cement. It's a cement-based board that delivers the look of wood with none of wood's weaknesses: it resists fire, moisture, rot, hail, and pests, and it won't warp in Missouri's temperature swings. Hardie products carry a 30-year non-prorated material warranty, and boards finished with ColorPlus® Technology — a baked-on factory finish — add a 15-year warranty on the finish itself, so you're not repainting every few years. It costs more than vinyl up front, but it's widely considered the best long-term value in siding, and some insurers even discount premiums for fiber cement homes. We'll give you side-by-side quotes so you can compare honestly.

“After a hailstorm, James walked our claim through step by step and got our whole roof covered. Clean crew, done in a day, and they left the yard spotless.”
“Honest from the first visit. They told us we didn't need a full replacement yet and did the repair for a fair price. That earned our trust for the next one.”
“Professional, veteran-owned, and they actually answer the phone. New GAF roof and gutters look fantastic. Would recommend to anyone in the area.”
