Types Of Roofing Nails

It is essential to know the types of roofing nails to understand when they can be applied and how they will match other roofing materials.

Let's delve into the five different types of roofing nails, their distinct characteristics, and how long they take to rust.

1. Aluminum Roofing Nails

This type of nail is made out of high-tensile aluminum alloy for bend resistance. It has a flat head with a bright silvery color that's pleasant to look at and can also serve as decoration. This roofing nail is usually used for metal roofs and shingles.

Aluminum roofing nails resist corrosion, bending, and provide proper hanging. Plus, they guarantee easy driving. They can last a lifetime or more or less than 10 to 20 years.

Despite that, this type of roofing nail is certainly not recommended for environments that are open to chemicals and salt like coastal areas; exposing them to these can cause them to eventually corrode.

2. Galvanized Roofing Nails

This roofing nail is basically a steel nail coated with Zinc. It's commonly used in asphalt shingles and known to last for a lifetime.

This type is resilient to rust; that's why the majority of professional roofers opt for this as a standard choice. There are two kinds of Galvanized roofing nails for you to choose from:

5. Button Cap Nails

Button cap nails are made up of steel shank and a large polyethylene cap that helps prevent leaks on the roof. It is usually applied to the roofing felt.

Its material is made of high carbon steel, and its plastic round head can vary in different colors. This type can also last for 10-20 years. However, the plastic cap may wear out for a year, depending on the type of environment it's exposed to.

Types Of Nail Shanks

Nail shanks do most of the holding when roofing nails are installed. The shank is forced between the fibers of the wood. When attached, the wood pressures against the shank, giving a tight grip.

There are three common types of nail shanks to help you understand how they work:

1. Smooth Shank

This type of nail shank has a smooth appearance and is considered the most economical type of nail because of its standard form. It's the easiest nail to drive, and the air consumption per nail can be lower.

2. Spiral Shank

This type of nail has a threaded appearance, almost looking like a screw that has visible helical twists. Spiral shanks help increase the force between fibers of wood, so this is quite difficult to remove.

3. Ring Shank

Ring shanks have a series of rings into the surface of the shank, and like the spiral shank, their air consumption is higher, and they have a tight grip once they are driven into wood.
