Hand Nailing Roof Shingles: Is It Better Than Using a Nail Gun?

By Birmingham Roofs

If you've started researching a new roof, you've probably come across the debate over hand nailing versus using a roofing nail gun. Some roofing companies advertise that they hand nail every roof, while others use pneumatic nail guns on every project. Naturally, homeowners begin to wonder which method is actually better.

The truth is that both methods can produce an excellent roof when they're done correctly. Modern roofing nail guns are the industry standard for a reason—they're fast, efficient, and when properly adjusted, they can install shingles just as effectively as hand nailing.

The difference isn't necessarily the tool. It's the level of quality control behind the person using it.

At Birmingham Roofs, we've installed shingles using both methods and have completed projects where hand nailing was required by the project specifications. Here's what homeowners should know before deciding whether hand nailing is worth the additional cost.

How Roof Shingles Are Installed

Every asphalt shingle manufacturer specifies:

• The correct number of nails

• The exact location where each nail should be installed

• The proper depth each nail should be driven

• The required fastening pattern for wind resistance

Whether those nails are driven with a hammer or a pneumatic nail gun, those requirements don't change.

A roof will only perform as well as the quality of its installation.

Roofing Nail Guns Are the Industry Standard

Today's professional roofing crews almost always install shingles using pneumatic roofing nail guns.

There are good reasons for that.

Nail guns allow crews to work efficiently, maintain a consistent installation pace, and complete projects much faster than would be possible by hand. When the equipment is properly calibrated and the installer pays attention to nail placement and depth, a nail gun can produce a roof that performs just as well as a hand-nailed roof.

The problem isn't the nail gun itself.

The challenge is making sure every gun stays properly adjusted throughout the entire installation.

Why Nail Gun Pressure Matters

A roofing nail gun relies on air pressure to drive every fastener.

If that pressure is too high, the nail can become overdriven, meaning the nail head punches through the surface of the shingle instead of holding it securely.

If the pressure is too low, the nail may remain underdriven, leaving the nail head sticking above the shingle where it can interfere with the next course.

Even if the pressure is perfect at the beginning of the day, conditions can change.

Different sections of roof decking may be softer or harder than others. Air compressors can fluctuate. Multiple installers may all be using different nail guns that require slightly different adjustments.

Experienced roofing crews continually monitor nail depth and adjust their equipment as needed.

Unfortunately, not every crew does.

Why Many Roofers Still Appreciate Hand Nailing

Hand nailing naturally provides more control over every individual fastener.

Instead of relying on air pressure, the roofer places each nail by hand and drives it with a roofing hammer until it is seated properly.

Because every nail is installed individually, it's much harder to accidentally overdrive the fastener.

The installer can actually see and feel the nail as it enters the decking and stop as soon as the nail head is properly seated against the shingle.

That additional control is one reason some architects, engineers, and project specifications still require hand nailing on certain jobs.

Hand Nailing Isn't Automatically Better

This is where a lot of articles become misleading.

Some claim that hand nailing always produces a stronger roof.

That simply isn't true.

A poorly trained installer with a hammer can still:

• Miss the manufacturer's nailing zone

• Use the wrong number of nails

• Install crooked shingles

• Damage shingles during installation

Likewise, an experienced crew using properly calibrated nail guns can install an outstanding roofing system.

The quality of the roof depends far more on the experience of the crew than whether they're holding a hammer or a nail gun.

Why Hand Nailing Can Reduce Mistakes

While hand nailing doesn't automatically create a better roof, it does slow the installation process.

That slower pace gives the installer more time to pay attention to:

• Proper nail placement

• Correct nail depth

• Shingle alignment

• Changes in roof decking

• Overall workmanship

It's difficult to rush when every nail is driven individually.

That slower, more deliberate process can reduce the chance of overlooked mistakes, especially on steep roofs or complex roof designs.

Projects That May Benefit from Hand Nailing

Hand nailing is often specified for projects where maximum attention to detail is required, including:

• Historic buildings

• Government and municipal projects

• Schools

• Custom homes

• High-end residential roofs

• Projects with strict architectural specifications

These projects often prioritize precision over production speed.

Is Hand Nailing Worth the Extra Cost?

Usually, hand nailing costs more.

Because every nail must be driven individually, labor increases significantly and projects take longer to complete.

For many homeowners, that additional expense may not be necessary.

A properly installed roof using calibrated pneumatic nail guns can provide decades of reliable performance when installed according to the manufacturer's specifications.

However, homeowners who want the added reassurance of individually driven nails—or projects where hand nailing is required—may decide the additional labor is worthwhile.

What Really Matters

Homeowners often spend a great deal of time asking whether a roofing company uses hand nailing or nail guns.

In reality, there are more important questions to ask.

For example:

• Do they follow the manufacturer's installation instructions?

• Do they use the correct number of nails?

• Do they inspect for overdriven or underdriven nails?

• Do they correct installation mistakes instead of covering them up?

• Do they have experienced installers?

Those questions will tell you much more about the quality of the finished roof than simply asking which tool they use.

Our Approach at Birmingham Roofs

At Birmingham Roofs, we don't believe a hammer automatically builds a better roof, nor do we believe a nail gun automatically creates problems.

Modern pneumatic roofing nail guns are the preferred installation method throughout the roofing industry because they are efficient and, when properly calibrated, can produce exceptional results.

What matters is taking the time to ensure every nail is placed in the correct location and driven to the proper depth. We continually monitor our equipment, inspect our work throughout the installation, and correct any improperly driven or misplaced nails before the roof is completed.

When a project requires hand nailing, we're fully equipped to complete it. When nail guns are the appropriate installation method, we make sure they're properly adjusted and used by experienced installers who understand that quality always comes before speed.

In the end, the best roof isn't determined by whether it was installed with a hammer or a nail gun.

It's determined by the workmanship of the people installing it.
