Are clips required for roof sheathing?
For the most common roof sheathing in our area, which is 1/2” nominal (7/16” actual) sheathing over trusses or rafters at 24” on center, there is no requirement for H-clips. One or two H-clips will often allow a longer span between roof trusses/rafters.
How do you use plywood sheathing clips?
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. Plywood clips are inserted by hand and the procedure is done in conjunction with installation of the sheathing.
How far apart should h-clips be?
pair of trusses, rafters, or joists. However, two (2) equally spaced H-clips are required between supports when spaced 48 inches on center. misfit of abutting sheets may be tolerated if gaps do not exceed maximum opening of 1/4 inch (6 mm).
Why are H-clips required for roof sheathing?
H-clips, also called panel-edge clips, are small steel devices that fit snugly between wood panels in order to provide them with edge support. They are often used with roof sheathing to keep it from feeling spongy or soft at its edges. Their size should match the thickness of the panels to which they are attached.
Are H clips required for 5/8 roof sheathing?
5/8” thick panels having a span rating of 40/20 can have an unsupported edge up to 32”. This means that 1/2” and 5/8” thick roofing panels that are supported by roof framing (rafters or trusses) spaced at the typical 16” or 24” o.c. do not require edge support (H-clips).

Does sheathing overlap fascia?

What is the minimum thickness of roof sheathing?
Sheathing must be a minimum of 19/32-inch thick. Never affix roof sheathing with staples; 8d ring-shank nails need to be used instead. The normal thickness range for sheathing is 3/8 to 3/4 inch.
Which is better for roofing OSB or plywood?
Plywood Holds the Moisture Advantage Over OSB When plywood gets wet, it tends to swell. OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.
