Bison Steel Buildings offer 3 Distinct Roofing Options:

• PBR Roof Panels (Standard on all Bison Buildings)
• Standing Seam
• Shingles

Our 26 gauge Purlin Bearing Rib Panels are far stronger than the commonly used "R" roof panels because they have an extended overlap to protect your valuable possessions from damaging water leaks and loss from theft. PBR roof panels come standard on all Bison Steel Buildings.

What the "Others*" offer:
29 guage is the thinnest steel sheeting that is normally allowed to be used for building, because it is thin and is attached to a wood purlin, contraction and expansion will cause movement and loosen around the fastner causing damaging leaks.
