Small clip. Big job. 🏠🔨
H-clips, also called panel edge clips, help support the unsupported edges of roof sheathing between rafters or trusses. They can reduce deflection, help keep panels aligned, and improve the overall performance of the roof deck.
Per IRC R803.2.2, allowable roof sheathing spans are tied to Table R503.2.1.1(1) and APA E30, which account for panel thickness, span rating, framing spacing, and edge support requirements. IRC R803.2.3 also governs roof sheathing installation.
Important: H-clips are not automatically required on every roof. Whether they are required depends on the sheathing thickness/span rating, framing spacing, manufacturer requirements, and engineered design.
It’s a tiny piece of metal most homeowners will never see—but when required, it plays an important role in keeping the roof deck properly supported.
Studied it. Built it. Now inspect it. 🦅
