Proper Intallation Of H Clips On Roof Shaething
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.
Proper intallation of h clips on roof shaething. 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. The connection between the roof sheathing and the structure is a vulnerable point that is known to fail during a hurricane. Keep these tips in mind when roofing in hurricane areas. Roof sheathing panel spacing hints.
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. Grip h clips are designed to make installing roof deck sheathing easier and faster with better spacing. Leaks at h clips with zip sheathing we recently installed a zip system roof over roof trusses spaced 24 inches on center. The lumberyard told us to install h clips as for conventional sheathing but after taping over all the seams between panels we found that water leaked through the tape at almost every clip.
Edge clip requirements depend on the relationship of the panel span rating to the actual distance between roof framing.
