What are roofing clips?

Roofing clips are small metal components used in construction to secure roofing materials. They are typically made of galvanized steel or stainless steel.

These clips are used to attach roofing panels, accommodate expansion and contraction, secure snow retention systems, stabilize tile or slate roofing, and improve installation efficiency.

What’s the purpose of using roofing clips?

Secure attachment

Roofing clips are used to securely attach roofing panels or materials to the underlying structure. They provide a strong connection that prevents the panels from lifting or shifting in high winds or extreme weather conditions.

Accommodate expansion and contraction

Roofing materials, particularly metal panels, expand and contract with temperature variations. Roofing clips allow for slight movement and help accommodate these thermal changes without causing stress or damage to the roof.

Prevent uplift

By securely fastening the roofing materials, roofing clips help prevent uplift, which is the upward force generated by wind that can dislodge or damage the roof. They play a crucial role in maintaining the structural integrity of the roof during storms or windy conditions.

Snow retention

In areas with heavy snowfall, roofing clips are used to attach snow retention systems or snow guards. These clips help hold the snow in place on the roof, preventing sudden snow slides or avalanches that can cause damage or pose a safety risk.

Stabilize tile or slate roofing

Roofing clips are often utilized in tile or slate roofing systems to provide stability. They help secure individual tiles or slates in place, preventing movement or displacement due to wind or other external forces.

Improve installation efficiency

Roofing clips contribute to the efficiency of roof installation. They provide a standardized method of attachment, allowing for faster and easier installation. Clips can be pre-installed on roofing panels or tiles, saving time and labor during the installation process.

Butterfly clips, also known as T-clips or T-bar clips, are used in suspended ceiling systems.

They are typically made of metal and are shaped like a butterfly with wings that extend to hold ceiling tiles in place.

These clips are easily adjustable and provide a secure attachment for ceiling tiles.

Standing seam clips

Standing seam clips are specifically designed for standing seam metal roofs.

They are typically made of metal and are attached to the standing seams of the roof panels.

These clips secure the roof panels together while allowing for thermal movement. They are often concealed, providing an aesthetically pleasing appearance to the roof.

H-clips

H-clips, also known as panel clips, are commonly used in plywood or OSB (oriented strand board) roof decking systems.

They are typically shaped like the letter “H” and are installed between adjacent roof panels.

H-clips provide support and help distribute the load evenly across the panels, reducing the risk of sagging or warping.

Seam clips

Seam clips are used in metal roof systems with overlapping panels.

They are designed to secure the seams where two adjacent panels meet.

Seam clips ensure a tight fit and prevent water infiltration at the seams, enhancing the roof’s weather resistance and durability.

Bermuda clips

Bermuda clips, also called tile roof clips or hurricane clips, are utilized in tile roof systems, particularly in regions prone to hurricanes or high winds.

These clips help secure individual roof tiles in place and provide resistance against uplift forces caused by strong winds.

Fixed clips

Fixed clips, also known as fixed fasteners, are commonly used in various roofing systems.

They are typically designed to provide a secure and permanent attachment of roofing materials to the underlying structure.

Fixed clips offer stability and resist movement, making them suitable for high-wind areas or when a rigid connection is required.

Expansion clips

Expansion clips, also referred to as movement clips or sliding clips, are used to accommodate thermal expansion and contraction of roofing materials.

These clips allow for slight movement of the roofing panels or tiles without causing stress or damage.

Expansion clips are often utilized in metal roofing systems to prevent buckling or warping due to temperature changes.

Bearing plates

Bearing plates, sometimes called load-bearing clips or purlin clips, are used to distribute the weight or load of the roof panels to the supporting structure.

They are typically larger and offer increased load-bearing capacity.

Bearing plates are commonly used in metal roofing systems or when there is a need to reinforce the attachment points of the roof.

Gutter hangers

Gutter hangers, also known as gutter clips or gutter brackets, are specialized clips used to attach gutters to the roof or fascia board.

They provide support and secure the gutters in place, ensuring proper water drainage from the roof.

Gutter hangers come in various designs, such as spike-and-ferrule hangers, strap hangers, or hidden hangers, depending on the gutter system and installation method.

Floating clips

Floating clips, also referred to as floating fasteners or floating roof clips, are used in certain roofing systems to allow for thermal expansion and contraction.

These clips have a floating or sliding mechanism that enables the roof panels to move slightly as they expand or contract due to temperature changes.

Floating clips help prevent stress and damage to the roof and ensure its long-term durability.

What materials are roofing clips made of?

  • Galvanized steel: Galvanized steel clips are widely used due to their durability, strength, and resistance to corrosion. The steel is coated with a layer of zinc, which provides protection against rust and extends the lifespan of the clips.
