When it comes to installing a new roof, the quality of the materials matters—but so does the method of installation. One of the most debated topics in the roofing industry is the difference between hand nailing and using a nail gun for shingle installation. While both techniques can result in a secure roof when done correctly, each has its own strengths and weaknesses, especially in a climate like Houston, TX, where extreme heat, humidity, and storm activity are common.
In this blog, we’ll explore the key differences between hand nailing and nail gun installation, and help you understand which method might be better suited for your home’s roofing project.
What Is Hand Nailing?
Hand nailing is the traditional method of installing shingles using a roofing hammer and individual roofing nails. The roofer manually places each nail, ensuring proper positioning, angle, and depth with every hit.
Pros of Hand Nailing:
- Precision: Each nail is driven to the exact depth and location, reducing the chance of overdriving or underdriving nails.
- Quality Control: Because it’s done by hand, experienced roofers can adapt to irregular surfaces and compensate for inconsistencies in decking.
- Better for Specialty Shingles: Some high-performance shingles, like those from Malarkey Roofing Products, benefit from the precision of hand nailing to ensure their advanced features are fully functional.
Cons of Hand Nailing:
- Slower Process: It takes significantly more time than using a nail gun, which may extend your installation timeline.
- Labor Intensive: Requires skilled roofers and consistent effort, which can increase labor costs.
What Is Nail Gun Installation?
A nail gun (or pneumatic nailer) is a tool powered by compressed air that drives nails into shingles quickly and consistently. It’s a common method on larger roofing projects due to its speed.
Pros of Nail Guns:
- Speed and Efficiency: Greatly reduces installation time, making it ideal for larger roofs or tight schedules.
- Consistency: When used correctly, it delivers uniform nail placement and depth.
- Reduced Physical Strain: Less fatigue for roofers compared to repetitive hammering.
Cons of Nail Guns:
- Risk of Overdriven or Angled Nails: Improper air pressure or user error can result in nails being driven too deep or at the wrong angle, potentially compromising the shingle’s integrity.
- Less Precision: Nail guns may struggle with uneven surfaces or require constant calibration for different decking materials.
Which Method Is Better?
The best method depends on several factors, including the skill of the roofer, the type of shingle, and the specific demands of the roof.
In climates like Houston’s, where high winds and storm impact are common, nail placement and depth accuracy are critical. A poorly driven nail can allow shingles to lift or detach, leading to leaks and costly damage.
Some manufacturers—especially those producing premium Class 4 impact-resistant shingles—may even specify installation methods in their warranty requirements. If hand nailing is recommended or required, using a nail gun could void your warranty.
That’s why working with an experienced contractor who knows how to use either method properly is far more important than the tool itself.
The Role of Workmanship in Roof Longevity
Regardless of whether hand nailing or nail guns are used, the most important factor is the roofer’s attention to detail and knowledge of correct shingle installation practices. Nailing patterns, spacing, pressure, and technique all affect the long-term performance of your roofing system.

Final Considerations
If you’re unsure which installation method is best for your home, talk with your roofing contractor. Ask how their team ensures quality control with each method and whether the shingle manufacturer has a preference.
While nail guns offer speed and efficiency, hand nailing provides control and precision—especially valuable on complex or high-end roofing systems.
Ultimately, the best choice is one that combines the right materials, the right technique, and the right installer. Read also our blog: Best Roofing Material Options for Homes in Texas
