are roof sheathing clips required
Minimum Thickness. Most roofs will be sheathed in plywood at least 3/8 inch thick. That will suffice on a roof with rafters set 16 inches apart with minimal roof loads. Loads will vary with the pitch of the roof; the flatter the roof, the greater the load on any one section. Steeper roofs will have lighter loads per square foot. Deformed-shank (i.e., ring- or screw-shank) nails are required. near ridges, gables, and eaves in areas with design wind speeds over 110 mph (3-second gust), but it is. Typical layout of roof. sheathing panels on. gable-end roof. Typical layout of roof. sheathing panels on hip. roof. Do not vent exhaust air. directly into roof cavity or attic. 3. Install baffles providing a minimum of. 1 inch of clear space between framing. and/or under roof sheathing at eaves to. insure that ceiling or roof insulation does. not block ventilation paths. For vaulted. or cathedral roof construction, provide. free ventilation path from eaves to ridge. Plywood sheathing is a structural building material used for residential and commercial construction. sheathing), wood species, adhesive type, the allowable roof and floor spans, and panel thickness. Plywood sheathing is made from lower density softwoods. the manufacturing process. In either case, the cost of the job is reduced. H-clips do not prevent wooden panels from buckling or warping. To the contrary, panels are more likely to buckle or warp when their room for expansion is limited, as is the case where H-clips are installed and panels are effectively connected to each other. H-Clips required on all deck sheathing on OSB or Plywood roof decks. What are the benefits of using H-clips?H-clips increase panel stiffness by allowing distribution of weight between adjacent panels. A panel is less likely to deflect when subjected to a heavy load near its edges if it is made stiffer. Rafters run from the peak of the roof to the eaves. They must be covered with some type of sheathing or decking before most finishing roof materials can be applied. The most common materials for this are oriented strand board (OSB) or plywood, both formed of layers of wood bonded into a panel. The flow diagram below shows the major elements of plywood sheathing. production. For residential construction, the building code requirement typically is for a rated sheathing panel of either OSB. or plywood of 0.95 cm (3/8in) thickness when sheathing is required, for shear wall sections; however, the as. 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. 20 ga. (33 mil) To assure best performance, follow these panel spacing and nailing recommendations for APA Rated Sheathing, APA Rated Sturd-I-Floor®, and APA Rated Siding. Spacing Hint: Use a 10d box nail to gauge 1/8-inch spacing between panels. Spacer-type panel edge clips may also be used for roof sheathing applications. Panel spacing is an APA RECOMMENDATION, to provide installers with a means of minimizing the potential for panel buckling; however, it is not a requirement.
Yes, it is required.
