Roof Sheathing Clip Spacing

Use a 10d box 0 128 inch by 3 inch nail as a spacer to gauge 1 8 inch edge and end spacing between panels.

Roof sheathing clip spacing.

H clips provide additional stiffness between bearing points for the unsupported edges of wood panel plywood or osb roof sheathing along with the necessary 1 8 gap for expansion as shown below illustrated on a bag of simpson h clips. Edge clip requirements depend on the relationship of the panel span rating to the actual distance between roof framing. Roof sheathing panel spacing hints. The most common rafter spacing is 24 inches and 5 8 inch plywood is recommended for that.

Spacer type panel edge clips may also be used for roof sheathing applications. Simpson strong tie panel sheathing clips are used to brace unsupported sheathing edges and provide a 1 8 gap to address shrinkage and expansion of roof sheathing. Plywood clips also referred to as h clips or panel edge clips are small metal brackets placed between the unsupported edges of plywood sheathing to effectively reduce the support spacing and stiffen the plywood. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame.

For improved performance consider thicker roof sheathing panels panel edge clips or panels with tongue and groove edges. Sheathing should be a minimum of 19 32 inch thick. A 1 8 inch space between adjacent panel end and edge joints is recommended unless panel manufacturer indicates otherwise. For rafters spaced 20 or more inches apart 1 2 or 5 8 inch plywood is recommended.

Spacer type panel edge clips may also be used for roof sheathing applications. Never attach roof sheathing with staples. The clips are inserted over the edges of the adjacent plywood panels to reduce deflection of the panel edges between the framing members and are most commonly used for roof sheathing. 8d ring shank nails should be used instead.

Some older h clips do not provide a built in gap. Spacer type panel edge clips are available from some manufacturers. Not always required but a good idea. Use a 10d box nail to gauge 1 8 inch spacing between panels.

A strong resilient roof is a home s first line of defense when the roof deck is exposed to weather.
