Should I use sheathing clips?

Should I use sheathing clips?

For the most common roof sheathing in our area, which is 1/2” nominal (7/16” actual) sheathing over trusses or rafters at 24” on center, there is no requirement for H-clips. One or two H-clips will often allow a longer span between roof trusses/rafters.

What is a sheathing clip?

A panel edge clip (often called an “H-clip” or “plywood clip”) is typically a small piece of galvanized metal that is placed between adjacent wood structural sheathing panels at a location between supporting joists or trusses and/or rafters to provide support to panel edges.

What are sheathing clips used for?

Panel sheathing clips are used to brace unsupported panel edges when sheathing meets edge-to-edge without a rafter for support.

What are ply clips?

Plywood clips, also referred to as H-clips or panel edge clips, are small metal brackets placed between the unsupported edges of plywood sheathing to effectively reduce the support spacing and stiffen the plywood.

What is the purpose of H clips on roof sheathing?

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. They are often used with roof sheathing to keep it from feeling spongy or soft at its edges.

Should roof sheathing have gaps?

The recommended maximum gap between roof sheathing boards for low-quality, 3-tab shingles is 1/4-inch. If asphalt shingles are installed over sheathing with gaps exceeding 1/4-inch, over time, these gaps may telegraph through and become visible.

Are plywood clips required by code?

Anyone installing 7/16″ OSB or plywood on 24 inch spans without end supports (clips) is in violation of “commonly accepted building standards” (the IRC) unless your jurisdiction has chosen to exclude that requirement by law.

Do you overhang roof sheathing?

When sheathing a roof, the first step is to snap a line so that the first row goes on straight. But if you snap it at 40 inches, then the sheathing will not project over the subfascia or true fascia. This opens the door to the possibility of water damage by letting gravity work against you. Don’t do that.

Are plywood clips code?

Can 7/16 OSB be used for roofing?

Standard types of wood designed for roof sheathing are oriented strand board, known as OSB, and plywood, the most popular being OSB. Sheets of 7/16-inch thick, without edge support, can be used in an area where the snow load is 30 pounds per square foot.

Can I use screws for roof sheathing?

Screws can be used for even greater withdrawal strength, but should be sized by the building designer. Staples are not recommended for roof sheathing attachment in high-wind areas. It is extremely important to have proper fastener spacing on all panels.
