Grip H Clip, Plywood Roof Sheathing Clip-19/32-5/8" GRIP PLY CLIP

Product Information

They create a connecting point along with a vital 1/8-inch gap for expansion and contraction between adjacent panels on roofs at unsupported edges perpendicular to roof trusses or rafters. We recommend placing the clip at the approximate middle point between each vertical framing member for 16-inch centered framing. Meanwhile, 24-inch centered framing requires two clips spaced equally between joists or rafters. How Many H-Clips Per Sheet of OSB? Unsurprisingly, H-Clips are used in many other applications beyond roofing. For instance, you can use H-Clips on ramp-style flooring projects and slanted walls. Again, the clips provide additional stiffness, reducing the risk of flexing, especially at the edges. The supported slanted walls or ramp-style floors can remain for a long time without structural issues.

This can cause roof panels to become loose with time. Therefore, many roofers prefer to use clips to keep the sheathing layers in place. Also see our blog posts Are H-clips required by the building code for roof sheathing? and What causes a lump or dip in the roof? Unfortunately, many roofers overlook them even where they can be crucial. Or worse, some use them wrongly.

What are the Benefits of Using H-Clips?

This may seem like a lot of money – and it is. However, it’s worth it, given that H-Clips significantly reduce the cost of installing a new roof. For instance, they reduce the number of materials needed, such as rafters.

Plywood Clips are not required for all roof sheathing projects, but they are recommended. They improve the longevity and durability of the plywood by ensuring that the plywood doesn't shift and become uneven over time. What are plywood clips used for? It further states that some panel clip types, when used alongside edge support, “automatically assure proper pane spacing” and recommends a panel clip per span and two clips for spans exceeding 48 inches. 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. Some older H-clips do not provide a built-in gap. Plywood clips are the same as H-Clips. Their main job is to provide extra support at panel edges, preventing sagging and increasing weight-bearing capacity at the edges. Furthermore, plywood H-Clips leave sufficient space between sheathing panels, enabling shrinking and expansion without structural damage. Where do H Clips Go on Roof Sheathing?However, many states have modified their building codes to overlook these regulations, even though others follow some requirements. Moreover, many homes were built before the requirements came into force. For instance, many people use 3/8-inch plywood sheathing for standard roofing applications. Unfortunately, 3/8-inch plywood is not strong enough to bear substantial weight. So, the panels often bow when subjected to excessive weight, such as when a roofer walks along the edges. The International Residential Code (IRC) requires H-Clips, according to a “law” that came into force in 2006. Also, see our blog posts What causes a sagging roof ridge line? and What causes a lump or dip in the roof? and What's the average lifespan of a roof?

For instance, you may need fewer rafters depending on your span combinations, resulting in cost savings. A few reports also indicate that H-Clips reduce labor requirements. Typical labor savings are 1.5 man hours per 2200 square foot home.

For instance, suppose you install different steep ramps in your home or business premise – one with H-Clips and the other without. After about a decade, you’ll notice sagging along the edges of the ramp without H-Clips. Meanwhile, the one with H-Clips will be intact. As a result, you end up replacing the ramp without H-Clips earlier. How Much Do H Clips Cost? Meanwhile, you can have unsupported edges up to 32 inches long if using 5/8-inch panels with a 40/20 rating, beyond which you need edge support. How Many H-Clips Per Sheet of Plywood? Also known as panel edge clips or plywood H clips, H Clips are metal clips that hold adjacent wood panels together while providing an expansion gap. Long Lasting - Hot Dipped Galvanized Steel: These plywood h clips are built to last! The steel goes through a hot dipped galvanizing process which protects the steel from corrosion. Hot dip galvanizing lasts much longer than the standard electro galvanizing process. In addition, the absence of H-Clips can cause the roof to sag between trusses. However, you want first to rule out other potential factors, like an extra thin sheathing or incorrect span between trusses. Improperly installed panels can also cause saggy roofs.

Manufacturers label them “panel edge clips,” but they are called H-clips in the construction trade because of their shape. An H-clip creates a connection point, along with a necessary 1/8” gap for expansion/contraction, between two sheets of plywood on a roof at the unsupported edges that run perpendicular to roof rafters or trusses. It should be placed at the center of the span for best results and gives the roof sheathing a little additional stiffness, because any load placed at the seam will be shared between both sheets of plywood. Better known as H-Clips, panel edge clips are commonly used between adjacent wood sheathing pieces between supporting trusses or rafters to provide additional stiffness at the panel edges. Installing H-Clips is easy. We strongly recommend professional installation for the best results. Nevertheless, you can do it yourself if you’ve some roofing experience.Plywood clips connect the panel edges of plywood, thus reinforcing the stability of the 2 pieces of plywood by ensuring they don't shift and become uneven over time. They are most commonly used in roofing but can be used for plywood walls as well. What are roof sheathing clips called? If you have ever wondered what H-Clips are for when resheathing your roof, this blog post is for you. We are going to be discussing what exactly H-Clips are and why you need them for your home. Let’s get started! What Are H-Clips? Let’s take the example of Florida. The Residential Edition of the Florida Building Code (FBC) refers to Table R503.2.1 of the APA for guidelines, which refers to H-Clips as “edge support.” The APA Engineered Wood Asociation says the following about edge support; Also Works For OSB: The H clips also work great for oriented strand board (OSB). OSB is an engineered wood panel that is used interchangeably with plywood.
