Proper intallation of h clips on roof shaething.

Roof sheathing panel spacing hints. Edge clip requirements depend on the relationship of the panel span rating to the actual distance between roof framing. The connection between the roof sheathing and the structure is a vulnerable point that is known to fail during a hurricane. Leaks at h clips with zip sheathing we recently installed a zip system roof over roof trusses spaced 24 inches on center.

During a hurricane the strength of the sheathing on the roof can greatly impact the homes ability to weather the storm. The installation of the new decking requires the use of h clips which are designed to provide a proper 1 8 spacing between the sheeting that allows for expansion and contraction between the sheeting. 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. This video shows how some roofs fail under heavy winds in uplift situations.

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.
