For improved performance consider thicker roof sheathing panels panel edge clips or panels with tongue and groove edges.
Placement of sheathing clips for roofing.
Sheathing should be a minimum of 19 32 inch thick.
Doing this means you can go to the hardware store and be sure that you are buying the right amount of clips.
8d ring shank nails should be used instead.
The thickness of ply you install can vary depending on your builder and how your roof trusses are spaced.
Never attach roof sheathing with staples.
Not always required but a good idea.
Keeps panels even for a level structural plane.
Generally 12 15mm ply is the most commonly used thickness.
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.
Some older h clips do not provide a built in gap.
A 1 8 inch space between adjacent panel end and edge joints is recommended unless panel manufacturer indicates otherwise.
The typical thickness range for sheathing is 3 8 to 3 4 inch.
Panel sheathing clips are used to brace unsupported panel edges when sheathing meets edge to edge without a rafter for support.
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.
Examine your roof for diagonal beams.
Space between plywood panels as recommended by the american plywood association.
Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame.
Edge clip requirements depend on the relationship of the panel span rating to the actual distance between roof framing.
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.
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.
Quick installation no nails required.
You ll need to ensure the line is square and the sheet finishes 10 30mm from the fascia.
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.
Spacer type panel edge clips are available from some manufacturers.
