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.
McElroy Metal offers five distinct standing seam systems that can be curved on the job site, lowering transportation costs and ensuring a proper fit.
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.
McElroy Metal standing seam systems are durable and weathertight, making them ideal for most any application.

Standing seam systems attach to the substructure with concealed fasteners. Since there are no exposed screws with washers than can shrink or crack over time, they are considered a more weather-tight system than exposed fastener systems.
Standing seam systems allow expansion and contraction through either a clip or slotted flange. Conversely, exposed fastener systems are pinned which can result in the fastener hole elongating over time and allowing water penetration. Check this out to learn more.
Some manufacturers (McElroy Metal included) can produce standing seam panels on-site in lengths up to 250’. Single-piece panels are quicker to install, more weathertight and require fewer components making them a superior and often more economical system.
Standing seam panels typically offer a distinct vertical leg. This tall vertical leg can offer a nice shadow effect and the illusion of a flat pan in between the major ribs which many architects and building owners prefer.
In order to meet stringent building codes and life safety issues, standing seam panels are subjected to more testing than exposed fastened type systems. Standard tests include uplift, air and water, impact, and fire resistance.
While additional charges and criteria typically apply, standing seam systems can often offer Weather Tightness Warranties where exposed fastener panel systems cannot.
