Roof clips, specifically metal roofing clips, are a fundamental component in installing standing seam and other types of metal roofing systems. They function as a concealed anchor used to attach metal panels to a substrate, such as a roof deck or other material.
Understanding Metal Roofing Clips
Metal roofing clips, sometimes referred to as cleats, are designed to secure metal panels to the structure beneath them without penetrating the visible surface of the panel. This creates a concealed fastening system, contributing to both aesthetics and weather resistance.
The Working Mechanism
The process of how roof clips work is straightforward and involves several steps:
- Attachment to Substrate: The clips are first fastened to whatever is beneath the metal panels, like a roofing deck or purlin. This means the clips are installed before the metal panels are put in place.
- Panel Engagement: As metal panels are laid down, the edges (or seams) of the panels are designed to hook onto or interlock with the pre-installed clips.
- Concealed Fastening: Once the panel edges are engaged, the clips hold the panels securely in place from underneath. The fasteners (screws, nails, etc.) used to attach the clips to the substrate are hidden from view, being underneath the panel seams.
This method ensures that fasteners do not puncture the flat surface of the metal panel, which is a common source of leaks in exposed fastener systems.
Key Benefits of Using Roof Clips
Using clips offers several advantages for metal roofing:
- Weather Protection: By hiding fasteners, clips minimize penetration points, significantly reducing the risk of water leaks.
- Thermal Movement Accommodation: Many clip systems, especially those used with standing seam roofs, are designed to allow panels to expand and contract with temperature changes. This prevents buckling or damage to the panels and fasteners over time.
- Improved Aesthetics: The absence of visible fasteners creates a clean, smooth roof appearance.
- Durability: Because fasteners are protected from direct exposure to weather elements, they are less likely to corrode, contributing to the overall longevity of the roof system.
Essentially, roof clips act as a hidden intermediary, connecting the metal roofing panels to the underlying structure securely and durably, while protecting the system from weather and accommodating natural material movement.
