Snap-Lok Nail Strip Metal Panels balance the classic lines of a standing seam metal roofing system with an eye toward budget. Using hidden screws to secure them to the roof deck, panels are seamed together simply by overlapping the male and female legs and snapping them together. No clips or mechanical seaming required. Snap-lok nail strip metal roofing panels don't require extensive experience to install making them a more affordable option, while still offering the durable, long-term performance of a standing seam system.
