H Clips Required Roof Sheathing

8d ring shank nails should be used instead.

H clips required roof sheathing.

Produced by apa the engineered wood association formerly the american plywood association in 1989. This video may depict some work practices that do not meet current safety standards. Not always required but a good idea. Never attach roof sheathing with staples.

The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures. Sheathing should be a minimum of 19 32 inch thick. The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process. They are often used with roof sheathing to keep it from feeling spongy or soft at its edges.

Avoid roof complaints with proper framing sheathing and roofing techniques. In either case the cost of the job is reduced. Some older h clips do not provide a built in gap. The typical thickness range for sheathing is 3 8 to 3 4 inch.

Always ensure your work site is compliant with current osha regulations. 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. 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. For 7 16 inch zip system panels huber engineered woods requires panel edge support blocking or approved edge clips if the on center spacing of the framing members exceeds 16 inches.

H clips may also allow builders to use thinner sheathing than they otherwise would be permitted to use. Their size should match the thickness of the panels to which they are attached. H clips do not prevent wooden panels from buckling or warping. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame.
