If you're a contractor, homebuilder, or even a do-it-yourselfer, knowing what PBR is and where it shines will allow you to make sound decisions when considering PBR for your next metal building job.
Below, we take a look at everything you need to know about PBR metal roofing panels, their makeup, pros, use cases, and applications, should you be looking to buy PBR in Los Angeles and its adjacent cities.
What Are PBR Panels?
BR panels are a type of metal roofing and siding panel with a higher wind resistance and carrying strength than the lower-profile R panels. The difference with PBR panel distance-wise is that the teardrop or leg on the panel is longer than your standard R panel. This lip overlays the panel next to it and sits on top of the purlin, providing additional strength to the roof and more support.
Fabricated from 26- or 24-gauge galvanized or galvalume steel, PBR metal panels are made to handle the most demanding weather conditions when used in roofing and siding that are built to last.
Key Features of PBR Metal Panels
- Rib Design: The ribs are usually spaced 12 inches apart and rise 1¼ inches, offering a clean and uniform look while improving load-bearing strength.
- Purlin Bearing Leg: The extended leg improves panel alignment and installation ease while reducing the chance of leaks.
- Weather Resistance: PBR panels are engineered to withstand rain, wind, and even hail, making them an excellent choice for buildings in a range of climates.
- Longevity: When properly installed and maintained, PBR metal roofing can last 40+ years.
- Versatility: Suitable for roofs with a minimum slope of 1:12 and for vertical or horizontal wall applications.

Advantages of PBR Panels
1. Strength and Support
The purlin bearing leg enhances panel alignment and adds strength to the structure. This allows for wider spacing between supports, potentially reducing framing costs.
2. Easy Installation
PBR panels are designed for quick and secure installation, especially in large-scale roofing or siding projects. Their interlocking system reduces labor time and ensures a tight seal.
3. Cost-Effective
Compared to traditional roofing materials, PBR metal roofing is more cost-efficient over time due to its long lifespan, low maintenance requirements, and energy efficiency.
