R-panel vs. PBR, in plain words
Both are ribbed steel panels. PBR adds a "purlin bearing rib," a small extra leg on the overlap edge that gives more support where panels lap over the framing. It's common on metal buildings. R-panel is the same basic shape without that extra leg. We'll recommend one based on your framing and what the building is used for.
The one thing to maintain: screws and washers
Every exposed screw has a rubber-type washer that seals the hole. After years of Texas sun those washers can crack and leak. That's why we:
- Drive screws straight and to the right torque. Over-driven or under-driven screws are the most common leak source.
- Seal laps, trim and penetrations correctly when we install
- Offer re-screw and washer replacement on older roofs. See metal roof repair.
Good fits
- Shops, hay barns, equipment sheds and horse barns
- Barndominiums. See barndo & shop roofs
- Farmhouses and ranch homes where the budget matters more than hiding the fasteners
- Re-roofing an old exposed-fastener roof that's leaking at the screws
Panel gauge
The R-panel we install is 26-gauge, the same gauge as our standing seam.
We own our roll-forming equipment and form our standing seam panels in-house.
