When it comes to securing asphalt shingles for your roofing project, the choice of roofing nails is paramount. In this concise guide, we will explore the technical details surrounding roofing nails, their uses, and what you need to know when it comes to asphalt shingles.
The Right Nails for Asphalt Shingles
Selecting the appropriate nails for asphalt shingles ensures a secure and long-lasting roof. The primary factors to consider are:
-
Nail Type: Roofing nails for asphalt shingles are typically available in two primary types: galvanized and electro-galvanized. Galvanized nails are corrosion-resistant, making them suitable for outdoor applications. Electro-galvanized nails are coated with a thin layer of zinc and are cost-effective but slightly less durable.
-
Nail Length: Roofing nails range from 1-1/4 inches to 2 inches in length. The appropriate length depends on the thickness of the shingles and local building codes.
-
Nail Shank Type: Roofing nails come with either smooth or ring shanks. Ring shank nails have ridges that enhance their grip, preventing shingle uplift during strong winds. They offer superior holding power, making them an ideal choice for asphalt shingles.
-
Nail Head Type: Roofing nails typically have large, flat heads that provide substantial holding power and minimize the risk of tearing through the shingles.
Nailing Technique
Proper nailing technique ensures the stability of your asphalt shingles:
-
Placement: Roofing nails should be driven approximately 1 inch above the cutout of the shingle and through the shingle’s tar strip. This placement ensures proper sealing and weather resistance.
-
Spacing: Nails should be spaced evenly and according to manufacturer recommendations, typically around 4 to 6 inches apart along the shingle’s edge. Proper spacing guarantees adequate attachment.
-
Penetration: Nails should be driven flush with the shingle’s surface, avoiding over-driving, which could damage the shingle or under-driving, which may lead to uplift during strong winds.
-
Overlapping: Overlap the shingles properly to ensure complete coverage and proper sealing. Consult the manufacturer’s guidelines for specific shingle installation instructions.
Using the Right Nailgun
For efficiency and accuracy, using a nailgun can be advantageous. When selecting a nailgun for asphalt shingles, consider these key features:
-
Nailgun Type: Pneumatic nailguns, powered by compressed air, are the preferred choice for professionals due to their power and efficiency. Cordless nailguns, powered by batteries, offer portability and convenience for smaller projects.
-
Magazine Capacity: A higher magazine capacity reduces the need for frequent reloading, increasing efficiency.
-
Depth Adjustment: The ability to adjust the nail’s depth ensures proper fastening without over-penetration or under-driving.
-
Safety Features: Look for nailguns with safety mechanisms to prevent accidental discharges and reduce the risk of injuries.
Conclusion
Selecting the right roofing nails and using the proper nailing technique is essential for a secure and durable asphalt shingle roof. Whether you’re a professional roofer or a DIY enthusiast, understanding these technical details will help you make informed choices for your roofing project. Prioritize the compatibility and durability of roofing nails to ensure your asphalt shingles remain firmly in place, offering protection and longevity to your roof.
