Nailing plywood can be tricky as it is used primarily for support. However, you can do it the right way by following these steps:

Choose the right nail size

Make sure nails with the correct head and shaft types are used for the job. An underlying ceiling or floor that has other materials working on the plywood will need flat heads on the ceiling nails.

It is not recommended to use a smooth roofing nail shaft where the plywood will not be lifted, as a rough shaft will help hold it.

Place the nail in the plywood

Place the nails you want to drive into the edge of the plywood (at least ½ inch). This is very important, but the distance will be determined by the size of the nail. Some roofing nails may require a gap of⅝ inchfrom the edge, while others may require ⅞-inch on the outside of the house.

Leave some space between the nails.

Giving the nails room to differentiate will reduce their combined ability to hold the plywood together. Not leaving enough space will cause them to become a load on the roof.

When the shaft of the nail enters the plywood, it will force the wood fibers apart, and too many chips can split the wood later.

Can roofing nails be hidden?

Yes, roofing nails can be hidden. All you need is a hammer and roofing cement. To do this, drive the head of the nail back into the roof every time you leave. then applyroofing cementor tar on the nail head evenly and let it dry.

Roofing cement is waterproof and can be used to seal nails, but it must be applied well. When you're done covering the area with cement, you can also cover it with a sheet of felt, as it's thick, unlike roofing cement.

Doing this will completely cover the head of the roofing nail, thus preventing damage to your home.

To end

There are different types of roofing nails, and they all serve different purposes. It is important to know the sizes of the nails and how best to use them, as well as the spaces required to ensure that the roof will survive for a long period of time. For 1/2 plywood, you can use 3/4" nails..
