Standing seam metal roofing panels are attached with concealed fasteners. Originally, clips engaged with the vertical legs and were used to attach the panel to the roofing substructure. As panel options have grown, however, it is common to see clipless panels included in this product family.

Standing seam systems are used for a wide range of applications and projects. These systems feature interlocking seams that connect panels, giving the roof a distinct, and attractive, appearance. Furthermore, standing seam systems are manufactured from high-end steel or aluminum offering years of low-maintenance service life.

Striations (also called stiffening ribs or rib rollers) are the “patterns” rollformed into a metal roofing panel between the seams. These can be used to assist with installing a metal roof, to help reduce the visibility of oil canning, or just for curb appeal. In fact, we recommend using striations in standing seam panels; some available options include:

• Flat – No indents between the seams
• Striated – Small, consistent indentation lines in the panel
• Ribbed – Shapes or indentations between the seams
• Clip relief – A stiffening rib adjacent to the seam that allows the space for a clip underneath
