H clips required roof sheathing.

This video may depict some work practices that do not meet current safety standards. 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. Their size should match the thickness of the panels to which they are attached. They are often used with roof sheathing to keep it from feeling spongy or soft at its edges.

Not always required but a good idea. 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.

Sheathing should be a minimum of 19 32 inch thick. The typical thickness range for sheathing is 3 8 to 3 4 inch. 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. 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.

Fasteners for asphalt shingles shall be galvanized steel stainless steel aluminum or copper roofing nails minimum 12 gage 0 105 inch 3 mm shank with a minimum 3 8 inch diameter 9 5 mm head complying with astm f1667 of a length to penetrate through the roofing materials and not less than 3 4 inch 19 1 mm into the roof sheathing. Avoid roof complaints with proper framing sheathing and roofing techniques. In either case the cost of the job is reduced. A builder who uses h clips may need fewer rafters to complete a project because the distance between them can be increased.
