Selecting the right nails for roofing is crucial to ensure a secure and long-lasting roof structure. In this guide, we’ll provide clear and concise information to help you make informed decisions about the best nails for your roofing projects.
Nail Types
When it comes to roofing, two primary nail types are commonly used:
1. Galvanized Roofing Nails:
- Material: Galvanized roofing nails are typically made of steel, coated with a layer of zinc to prevent rust and corrosion.
- Types: They come in different styles, such as smooth shank, ring shank, or screw shank, with varying holding power and resistance to pull-out.
- Usage: Galvanized roofing nails are suitable for a wide range of roofing materials, including asphalt shingles, wood shingles, and cedar shakes.
2. Coil Roofing Nails:
- Material: These nails are also made of steel and come with a galvanized coating for corrosion resistance.
- Types: Coil roofing nails are specifically designed for use in pneumatic nail guns.
- Usage: Ideal for high-volume roofing projects, such as attaching asphalt shingles. They offer excellent speed and efficiency.
Nail Length
The nail length you choose depends on the roofing material and the roof deck’s thickness:
-
Asphalt Shingles: For asphalt shingles, common nail lengths range from 1-1/4 inches to 1-3/4 inches, depending on the shingle’s thickness and the roof deck material. Always consult the manufacturer’s guidelines for the exact nail length required for your shingles.
-
Wood Shingles and Shakes: Nails for wood shingles or shakes should penetrate through the material, the roof deck, and into the rafters. Nail lengths typically vary from 1-3/4 inches to 2-1/2 inches.
Shank Style
The shank style of the nails can significantly impact their holding power:
-
Smooth Shank: These nails have a smooth surface and are easier to drive. They offer less holding power compared to other shank types and are suitable for roofing materials like asphalt shingles with low weight.
-
Ring Shank: Ring shank nails have rings or ridges along the shank, providing superior holding power. They are ideal for securing heavier roofing materials, such as wood shakes.
-
Screw Shank: Screw shank nails have spiral threads around the shank, offering the highest level of holding power. They are excellent for securing wood shingles or shakes, especially in regions with high wind exposure.
Nails per Square
The recommended number of nails per square for roofing materials can vary:
-
Asphalt Shingles: Typically, asphalt shingles require four nails per shingle. However, always check the manufacturer’s guidelines as this can vary.
-
Wood Shingles and Shakes: Wooden roofing materials often require two nails per piece, with one near the top and the other near the bottom.
Manufacturer Guidelines
Always consult the manufacturer’s guidelines for your specific roofing material. Manufacturers provide detailed instructions regarding the type, length, and quantity of nails required for optimal performance and warranty compliance.
In conclusion, choosing the best nails for your roofing project involves considering the type of roofing material, nail length, shank style, and manufacturer guidelines. By selecting the right nails, you’ll ensure the stability and longevity of your roof, providing peace of mind for years to come. Whether you’re a professional roofer or a homeowner embarking on a roofing project, this guide will help you make informed decisions about the nails you use.
