When it comes to roofing, using the right type of nail is crucial for ensuring the longevity and structural integrity of your roofing project. Rolled roofing, often used for low-slope or flat roofs, has specific requirements for nails to prevent leaks and secure the material effectively. In this article, we’ll explore the types of nails suitable for rolled roofing and provide a detailed guide to help both technical and non-technical audiences choose the right nail for the job.
- Roofing Nails vs. Standard Nails
Before diving into the specifics, it’s essential to understand the difference between roofing nails and standard nails. Roofing nails are specifically designed for securing roofing materials. They are made of materials that resist corrosion, ensuring they can withstand the elements for an extended period. Standard nails, on the other hand, may not have these properties and are not ideal for roofing projects.
- Rolled Roofing Nails
For rolled roofing, there are two main types of roofing nails to consider: galvanized and roofing cap nails.
2.1 Galvanized Nails
Galvanized nails are the most commonly used type for rolled roofing. They are made of steel coated with a layer of zinc, which provides excellent corrosion resistance. Galvanized nails come in various lengths and thicknesses, making it easy to match them to the thickness of your rolled roofing material.
Key Points:
- Galvanized nails are highly corrosion-resistant.
- Choose the nail length and thickness that matches your rolled roofing material.
- They can be either smooth or have a ring shank for improved grip.
2.2 Roofing Cap Nails
Roofing cap nails are specifically designed for rolled roofing, making them an excellent choice for this type of project. They have a plastic or metal cap that offers additional protection against moisture penetration. Roofing cap nails are available in various lengths to accommodate different rolled roofing materials.
Key Points:
- Roofing cap nails come with a protective cap to enhance weather resistance.
- Like galvanized nails, choose the appropriate length for your specific rolled roofing material.
- Nail Length and Thickness
Selecting the right nail length and thickness is essential for secure and weather-resistant installation. To determine the correct nail size:
- Consult the manufacturer’s recommendations for the rolled roofing material you are using.
- The nail should penetrate the roofing material and underlayment, securing it to the roof deck but not penetrate through it.
- Installation Tips
Here are some tips for a successful rolled roofing nail installation:
- Space the nails evenly, typically 6 to 12 inches apart along the seams of the rolled roofing material.
- Ensure the nails are driven perpendicular to the roof surface to avoid creating gaps where water can seep in.
- Use a hammer or nail gun designed for roofing to drive the nails.
Conclusion
Choosing the right nails for your rolled roofing project is a critical decision that can impact the roof’s lifespan and the overall integrity of your structure. Galvanized nails and roofing cap nails are your best options, thanks to their corrosion resistance and design tailored for roofing. Always follow the manufacturer’s recommendations regarding nail size and spacing, and ensure the nails are driven perpendicular to the roof surface for a watertight seal. By following these guidelines, both technical and non-technical individuals can ensure a successful rolled roofing installation that stands the test of time.
