Exposed nails on an open 2 x 6 roof can compromise both the aesthetics and functionality of the structure. This article provides a clear and concise guide on addressing this issue, offering practical solutions for both technical experts and homeowners.

I. Understanding the Problem:
A. Common Causes:
1. Exposed nails may result from natural expansion and contraction of wood.
2. Weather conditions, such as extreme heat or cold, can contribute to the movement of wood and the subsequent exposure of nails.

II. Choosing the Right Nails:
A. Length and Gauge:
1. Select nails that are long enough to penetrate through the roof sheathing and into the underlying structure.
2. The gauge of the nails should be appropriate for the thickness of the roof sheathing.

B. Corrosion Resistance:
1. Opt for nails with corrosion-resistant coatings to prevent rust, especially in areas prone to moisture exposure.
2. Stainless steel or galvanized nails are suitable for outdoor applications.

III. Materials and Tools:
A. Hammer or Nail Gun:
1. Use a hammer or a nail gun to drive the nails back into the roof sheathing.
2. Nail guns are efficient for large-scale projects, while hammers provide precise control for smaller repairs.

B. Putty or Wood Filler:
1. Choose a high-quality putty or wood filler that matches the color of the roof sheathing.
2. The filler should be weather-resistant and suitable for outdoor use.

IV. Step-by-Step Repair Process:
A. Secure the Nails:
1. Using a hammer or nail gun, carefully drive the exposed nails back into the roof sheathing.
2. Ensure the nails are flush with the surface to prevent future exposure.

B. Apply Putty or Wood Filler:
1. Fill the depressions left by the nails with the chosen putty or wood filler.
2. Smooth the filler with a putty knife for a seamless finish.

C. Sand and Paint (Optional):
1. Once the filler is dry, sand the patched area to create a smooth surface.
2. Optionally, paint the repaired section to match the color of the roof sheathing.

V. Preventive Measures:
A. Use Proper Nailing Techniques:
1. When installing roof sheathing, use proper nailing techniques to minimize the risk of nails protruding over time.
2. Follow recommended nailing patterns and spacing guidelines.

B. Regular Inspections:
1. Conduct periodic inspections of the roof to identify and address exposed nails promptly.
2. Address any issues with movement or expansion of the wood promptly to prevent further exposure.

Conclusion:
Effectively addressing exposed nails on an open 2 x 6 roof involves a straightforward process of securing the nails and patching the affected areas. By choosing the right materials and tools, homeowners and professionals alike can achieve a durable and aesthetically pleasing repair. Additionally, incorporating preventive measures during roof installation and conducting regular inspections can contribute to the long-term integrity of the roof.
