What are the clips required between many sheathing panels called?

The clips required between many sheathing panels are known as H-clips. These clips are specifically designed to support the edges of the panels and maintain a gap between them, which is crucial for allowing expansion and contraction due to temperature fluctuations. By providing this structural support, H-clips help to prevent sagging of the roofing panels, ensuring a more durable and stable roof system.

H-clips are typically used with plywood or oriented strand board (OSB) sheathing and are essential in creating a continuous and stable surface for roofing materials to be applied. This helps avoid potential issues such as uneven surfaces and premature wear on roofing materials, enhancing the overall performance and longevity of the roof system. Other clip types may exist but serve different purposes or may not be commonly used for sheathing panels.
