![]() ![]() The stainless fastening clips and screws ensure secure and lasting attachment with no chance for problems resulting from expansion and contraction. ![]() Additionally, in comparison to most agricultural panels, ClickLock has all concealed fasteners, eliminating failure-prone rubber washers beneath exposed screw heads.įor homeowners who want a metal roof with a traditional appearance, ClickLock is designed to be the best. Manufactured from heavy-duty, rust-free aluminum, ClickLock stands apart from most standing seam panels that are steel. The highest quality standing seam systems will have PVDF coatings noted for their fade and chalk resistance.ĬlickLock has been engineered in narrow 12” panels for a clean, contemporary look that is architecturally scaled for the scale of any home rather than for the larger scale of a barn or shopping center. Additionally, standing seam panels and their accessories are designed to have only concealed fasteners. These panels are designed with clip fasteners that allow the metal roofing panels to float as needed with the naturally occurring expansion and contraction of the metal caused by temperature changes. Many of these products also have lower quality coatings.ĬlickLock – Concealed Fastener Standing Seam This causes ripples to appear in the panels. If the fasteners are over-driven or if the fasteners are not all located exactly in the middle of the slotted hole, the allowance for expansion is ruined. These panels have a nailing strip running down one side, usually with elongated holes designed to allow for the expansion and contraction of the roof panels. This causes fastener holes to wallow out and fasteners to back out or even break over time. As a result, the fasteners bear the forces of thermal movement. These panels have no built-in allowance for the metal’s movement with temperature change. Also called “exposed fastener”, these are sheets of corrugated metal that laid on the roof, with screws are driven through them to secure them to the roof deck.
