Which panel is better for a low-slope roof?

The PBR Panel. It is rated down to a 1:12 slope, while the Panel-Loc Plus needs at least 2-1/2:12.

Is the PBR Panel worth the higher price?

If you need 26 gauge steel, a shallow pitch, or tested impact and fire ratings, yes. For a steep barn roof where 29 gauge is acceptable, the Panel-Loc Plus costs far less.

The PBR Panel has the edge on paper: thicker 26 gauge steel, a purlin-bearing overlap, and a 40-year peel and 30-year chalk/fade paint warranty. The Panel-Loc Plus publishes no paint warranty.

Can either be used on siding?

The PBR Panel is sold for both roofing and siding. The Panel-Loc Plus is described for roofing applications.

Do both use exposed fasteners?

Yes. Both are exposed-fastener panels, so screw placement and gasketed fasteners matter on each.

The listings are $38.00 for the Panel-Loc Plus at PBS Direct and $179.99 for the PBR Panel at Amazon as of November 6, 2026, but they may cover different lengths. Check the length and coverage on each before comparing.
