The following is a guide on how to install roof sheathing. Sheathing is the boards or panels that make up the roof structure. They are fastened to the roof rafters or trusses to provide a nailing surface for the shingles or other exterior roofing material.

To install roof sheathing, you will need the following materials: roofing felt, staples, 1×6 lumber, and a hammer. First, measure the length and width of your roof and cut the lumber to size. Next, staple the roofing felt to the roof, making sure to overlap the edges. Once the felt is in place, start nailing the lumber to the roof, starting at the bottom and working your way up. Make sure to nail each board into place before moving on to the next.

How do you fasten roof sheathing?

Fasteners should be 3/8 inch from the panel edges. For ordinary applications, nails should be 8d common or better. For best results, use 16d nails for heavier applications.

When installing panels, be sure to space them 1/8 inch apart at the panel ends and edges, as well as around windows and doors. This will ensure proper ventilation and avoid any gaps that could let in outside air.

What nails should be used for sheathing

When selecting galvanized steel for your fasteners, be sure to use nails that are at least 12-gauge or thicker. The length of the nail you need to use will depend on the thickness of the sheathing and shingles. For the best performance from your fastener, use nails that are made of hot-dipped galvanized steel.

If your roof sheathing is installed without H-Clips, your roof decking might buckle on itself during regular expansion and contraction of the wood. This can cause waves and bumps on your roof. In addition, this could lead to poor water drainage and eventual leaks.

Is it better to nail or screw roof sheathing?

Nails are a popular selection for roofing, siding and sheathing projects The amount of fasteners that are needed in these projects makes nails a more attractive choice because they offer a lower price point.

Nails are often preferred for structural joining, including framing walls, because they are more flexible under pressure, whereas screws can snap. Nails are also called upon when securing plywood sheathing for exterior walls, installing hardwood floors, and attaching siding and to install roof sheathing_1

Does roof sheathing need to be glued down?

It is important to take care when installing roof sheathing, as improper installation can lead to problems down the road. Unlike flooring, DO NOT glue roof sheathing. Drive nails flush to the panel, but avoid over-driving nails through the panel surface, especially when using a power-driven tool.

The code has been very consistent over the years when it comes to the maximum allowed spacing between nails for unblocked roof plywood. Conventionally, the maximum spacing allowed is 6” on the short edges of panels that are supported, and 12” on center “in the field” at intermediate supporting rafters.

Should I tape seams of sheathing

Air sealing tape is a great way to seal the seams of OSB sheathing. Air leakage is never good, so if you think that “walls need to breathe” means “walls need to leak air,” you are wrong. The best tapes for taping OSB seams are Siga Wigluv, Huber Zip System tape, and 3M All Weather flashing tape.

The N75C-1 is a high-volume coil sheathing/siding nailer that is perfect for use with wall and roof sheathing. It can drive 15-degree wire weld collated and plastic inserted nails with shank diameters of 0.090 to 0.131 inches. It has a lightweight aluminum design for added durability.

Can you staple zip sheathing?

From the table above, it can be seen that the fastener spacing requirements change depending on the sheathing thickness, fastener type, and the load being applied to the sheathing. For instance, when applying 5/8″ plywood sheathing to a framing member with a stud spacing of 16″ o.c., the minimum fastener spacing would need to be 6″ o.c. when using 8d common nails, or 4″ o.c. when using 16d common nails. However, if the framing member was 24″ o.c., the minimum fastener spacing would increase to 8″ o.c. when using 8d common nails, or 6″ o.c. when using 16d common nails.

In order to ensure the correct placement of the sheathing, the edge of the sheet should line up perfectly with the outer wall. The other end of the sheet should be placed on the center of a stud. If the edges do not line up, a construction level can be used to determine if the corner of the wall is off or the stud is not plumb.

Can you use 7 16 zip sheathing on a roof

The green and sienna ZIP System sheathing panels can be used interchangeably for the wall or roof. The green panel denotes a 7/16-inch panel while the sienna panel denotes either a 1/2-inch or 5/8-inch panel.

The most common issues associated with damaged roof sheathing are: excessively high heating and cooling costs, premature wear on shingles, water leaks, mold in your attic, rotting roof trusses, water stains on your ceilings and walls, and insect infestations.

Can I use 3/4 inch plywood for a roof sheathing?

There are several factors to consider when deciding on the thickness of plywood for roof sheathing, including the pitch of the roof and the loads that the roof will need to support. 1/2-inch CDX plywood is the traditional choice for 24-inch rafter spacing, but roofs with less pitch may require the use of 3/4-inch CDX plywood to support the heavier loads, such as snow and ice accumulation in the winter.

The recommended length for roofing nails is 19 mm. This is to ensure that the nails are long enough to penetrate the roofing material and go into the OSB, solid wood, plywood or non-veneer wood decking. If the nails are not long enough, they may not provide a secure hold and could come loose over to install roof sheathing_2

Is it better to use plywood or OSB on a roof

Plywood is better at absorbing moisture than OSB, but it also dries out quicker. Both products will swell when wet, but plywood will return to its original shape when it dries. OSB is less forgiving of being left out in the rain and will show more deformities after a wetting and drying cycle.

There are different types of galvanization, but the most important one for roofing nails is hot-dip galvanization. This is where the steel is dipped in a molten zinc bath, which provides a thick and durable layer of protection.


There are a few different ways that you can install roof sheathing, but the most common method is to use nails or screws. You will need to start by measuring the area where you will be installing the sheathing and then cutting the panels to size. Once the panels are cut, you will need to position them on the roof and then fasten them into place with either nails or screws.

Installing roof sheathing is a relatively simple process that can be completed in a few hours. The most important thing to remember is to use the proper sized sheathing for your roof. If you use too small of sheathing, it will not provide enough support for your roof and could lead to problems down the line. Too large of sheathing will be more difficult to install and could also cause problems. With the proper sized sheathing, the process is relatively straight forward and can be completed quickly and easily.
