Roll roofing is a cost-effective and efficient solution for low-slope roofs. Choosing the right nails for roll roofing installation is crucial to ensure the longevity and durability of your roofing project. In this article, we’ll discuss the technical details and considerations to help you select the best nails for your roll roofing needs.

1. Understanding Roll Roofing

Before we delve into nail selection, let’s briefly clarify what roll roofing is and where it’s typically used:

• Roll Roofing: Roll roofing, also known as mineral-surfaced roofing, is a lightweight asphalt-based roofing material that comes in rolls. It’s designed for use on low-slope or flat roofs, such as porches, sheds, and other small structures.

• Roll Roofing Installation: Proper installation of roll roofing involves securing the material to the roof deck with nails. The nails play a crucial role in keeping the roofing material in place and ensuring it can withstand the elements.

2. Technical Details for Nails

Selecting the right nails for roll roofing is essential to prevent leaks and ensure long-term performance. Consider the following technical details:

• Nail Type: Use roofing nails specifically designed for roll roofing. These nails are often galvanized or coated with a weather-resistant material to prevent rust and corrosion.

• Length: The length of the nails should be appropriate to penetrate the roofing material and secure it to the roof deck. Generally, nails between 1.25 to 1.5 inches in length are suitable for roll roofing.

• Nail Head: Roofing nails typically have a large, flat head. This design helps to securely hold down the roofing material and prevent it from lifting in strong winds.

• Shank: Roofing nails have a smooth shank, which offers a secure grip on the roofing material. The smooth shank design also helps prevent water penetration.

3. Nailing Pattern and Spacing

Proper nail placement and spacing are crucial for the effectiveness of your roll roofing installation. Follow these guidelines:

• Spacing: Typically, nails should be spaced approximately 3 to 4 inches apart along the edges of the roll roofing material and 6 to 8 inches apart in the field. However, consult the manufacturer’s instructions for specific recommendations.

• Edge Nailing: Start by nailing along the edges of the roll roofing, securing it firmly to the roof deck.

• Field Nailing: After the edges, work your way toward the center, ensuring that the nails are evenly spaced.

4. Roofing Cement

To enhance the seal and waterproofing of the roofing, it’s recommended to use roofing cement. Apply a layer of roofing cement around the perimeter and seams of the roll roofing material before nailing. This added layer of protection will help prevent water infiltration.

Conclusion

Selecting the best nails for roll roofing is a crucial step in ensuring the longevity and effectiveness of your roofing project. Stick to roofing nails with the right length, head, and shank, and follow the recommended nailing pattern and spacing guidelines. Additionally, using roofing cement can further enhance the waterproofing and longevity of your roll roofing installation.

By paying attention to these technical details, you can have confidence in the reliability and performance of your roll roofing, protecting your structure from the elements for years to come.
