What is R-Panel (PBR Panel)?
R-Panel and PBR Panel are the same profile — PBR (Purlin-Bearing R-Panel) is the modern industry name for what’s commonly still called R-Panel in the field. 36″ cover width, 1¼” major ribs spaced 12″ on-center, and a purlin-bearing leg so the panel works as roofing OR siding. Our R-Panel is 26-gauge Grade 80 steel — the contractor standard for residential roofs, carports, barns, barndominiums, and commercial roofs across Houston and Southeast Texas.
Why Light Stone
Light Stone is the warm beige / tan color — the panel that pairs cleanly with brick, stucco, limestone, and Hill Country palettes. It’s a favorite on agricultural buildings that need to disappear into the landscape and on residential builds wanting a roof color softer than grey but more refined than tan paint. Light Stone is also the #1 siding choice in the two-tone barndominium look — Light Stone walls under a Charcoal Grey or Matte Black roof is the dominant 2026 build.
SMP paint — what it actually is
Silicone-Modified Polyester (SMP) is the contractor-standard mid-tier coil paint. It handles UV exposure, heat cycling, and Gulf Coast humidity — the three things a Houston roof actually deals with. The Sherwin-Williams WeatherXL system carries a 40-year chip/peel warranty and 30-year fade/chalk warranty out of the box. Less expensive than premium PVDF/Kynar; far more durable than budget polyester paint.

FAQ
What’s the difference between 26-gauge and 29-gauge?
26-gauge is 0.0185″ thick — the contractor standard for Houston roofing. 29-gauge is thinner (~0.0142″) and used on cheap residential jobs. For Gulf Coast hail and wind, 26-gauge is the floor.
Will my Light Stone color match if I come back for more later?
We run from a single mill coil per color. Color batches can drift slightly between mill runs (industry-wide reality). For perfect match, buy all you need in one trip — we cut to your exact list. If you’ll need touch-up later, grab the batch tag stamped on your coil end before you leave.
Is “same-day cut” really same-day?
For orders up to about 2,000 linear feet of stock colors, yes — call with your footage, drive over, we cut while you load. Bigger orders may need 24 hours to schedule the shear clean.
Do you deliver?
Yes. Pickup is free at our Houston yard; delivery is available across the Houston metro and most of Southeast Texas (free on orders $1,500+). Call (281) 902-7619 for a delivery quote.
