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