Roofing nails are a key part of any roof’s installation. They are used to attach roof tiles, sheet metal, and felt underlayment. They can be made from a variety of materials, and have different shapes and sizes. They can be rust resistant, water resistant, and durable.
The most common material used in roofing nails is aluminum, but it is more prone to rusting and reacting with chemicals. Stainless steel is also used in some roofing applications. Stainless steel nails are more expensive than aluminum nails, but they are also more durable.
Copper nails are also used for roofing. These nails are known for their rust resistance. Copper nails are also known for their long lifespans. Copper nails can be used to fasten roofing materials to harder woods, but they do not work well with soft wood.
Spiral thread nails have a spiral thread shank that helps the nail twist in when it is driven into the material. These nails also have an increased withdrawal capacity. These nails are made from several rings to increase the holding power. They are also designed to lock during installation.
Galvanized nails are coated in zinc, which makes them rust resistant. These nails are also available in a stocky, galvanized version. The zinc coating will wear off over time.
The other two types of nails are smooth and screw shank nails. Screw shank nails are twisted nails with diamond-shaped tips. These nails work well for fastening wood roofing and other dense materials. They are also suited for use in harsh weather conditions.
