What Exactly Are Roofing Nailers?
Roofing nailers are specialized power tools designed specifically for attaching roofing materials, primarily asphalt shingles, to the roof deck. They are built for speed and efficiency, driving nails consistently and quickly, which is crucial for large roofing jobs where time is of the essence. Unlike framing nailers or finish nailers, roofing nailers have specific features to handle the unique demands of roofing work.
These tools are designed to drive nails at a specific depth, ensuring that the nail head is flush with the shingle surface but not so deep that it damages the shingle or so shallow that it leaves the shingle unsecured. This consistent depth is vital for the long-term performance and weather resistance of your roof. They are typically pneumatic (air-powered), requiring an air compressor, though some electric models are available.
The Two Main Players: Coil vs. Strip Roofing Nailers
When you start looking into roofing nailers, you’ll quickly notice two primary designs: coil roofing nailers and strip roofing nailers. While they both do the same job – drive nails into your roof deck – they go about it in different ways, and each has its own set of advantages and disadvantages.
Choosing between them often comes down to the scale of your project, your personal preference for handling tools, and the specific type of roofing material you’re working with. Let’s dive into what makes each one tick.
Coil Roofing Nailers: The Marathon Runners
Coil roofing nailers live up to their name by using nails that are collated in a coil. Imagine a roll of nails, similar to how you might see staples or a roll of tape. These coils are fed into the nailer’s magazine, which typically holds a large number of nails, often between 100 and 120.
This high capacity is their biggest selling point. Because they hold so many nails, you can fire off hundreds of nails before needing to reload. This dramatically speeds up the process, especially on large, straightforward roofing jobs. Think of installing new shingles over an entire house – that’s where a coil nailer truly shines.
How They Work
The nails in a coil are held together by wire or plastic. As the nailer drives a nail, it pulls the next one from the coil through a feed mechanism. The magazine is usually long and angled, allowing the coil to feed smoothly into the firing chamber. This design allows for a very rapid firing rate.
They are also known for their balance and ergonomics, generally designed to be comfortable to hold and operate for extended periods. The bulk of the tool, due to the coil magazine, is often positioned over the handle, leading to a balanced feel for many users.
Pros of Coil Roofing Nailers:
- High Capacity: Holds a large number of nails (100-120 per coil), meaning fewer interruptions for reloading.
- Speed and Efficiency: Ideal for large roofing projects where time is a critical factor. You can cover a lot of ground quickly.
- Less Fatigue on Large Jobs: Fewer reloads mean less stopping and starting, which can reduce overall fatigue on extensive projects.
- Consistent Nailing: Generally provide very consistent nail depth, essential for secure shingle installation.
- Good Balance: Many models are designed for comfortable, balanced handling during prolonged use.
Cons of Coil Roofing Nailers:
- Bulkier Design: The coil magazine can make them larger and less maneuverable in tight spaces or awkward angles.
- Nail Availability: You need to ensure you have the correct type and size of collated nails for your specific coil nailer. They aren’t as universally available as strip nails in some areas.
- Potential for Nail Misfires (Rare): Occasionally, a coil of nails might have an issue with the collation, though this is uncommon with quality nails.
- Weight: Due to the magazine and coil capacity, they can be slightly heavier than some strip nailer models, though this is often offset by better balance.
Strip Roofing Nailers: The Nimble Navigators
Strip roofing nailers, on the other hand, use nails that are collated in a straight line, much like a strip of staples you might see in a stapler. These strips are typically shorter and hold fewer nails, usually ranging from 60 to 100, depending on the model and nail size.
Their advantage lies in their generally more compact and lighter design, making them easier to handle and maneuver in confined or awkward areas of the roof. If you’re working on a small shed roof, a bay window, or doing repairs in tricky spots, a strip roofing nailer might be your best friend.
How They Work
The nails in a strip are held together by a plastic or metal collation strip. As a nail is fired, the strip is pushed forward, presenting the next nail for driving. The magazine for a strip nailer is typically straight and slimmer than that of a coil nailer.
This design allows strip nailers to be more agile. They can get into tighter corners, around vents, and under eaves with more ease. While they require more frequent reloading than coil nailers, the reloading process itself is usually very straightforward and quick.
Pros of Strip Roofing Nailers:
- Maneuverability: Their slimmer profile makes them excellent for tight spaces, corners, and complex roof sections.
- Lighter Weight: Often lighter than coil nailers, which can reduce fatigue during extended use, especially when working overhead.
- Easier to Handle in Awkward Positions: The more compact design makes them less cumbersome when working on steep slopes or in confined areas.
- Nail Variety: Strip nails can sometimes be more readily available in various sizes and types depending on your local hardware store.
- Simpler Design: Can sometimes be less complex mechanically, potentially leading to easier maintenance for some users.
Cons of Strip Roofing Nailers:
- Lower Nail Capacity: Require more frequent reloading (typically 60-100 nails per strip), which can slow down work on large projects.
- Slower for Large Projects: The constant need to reload can significantly slow down installation on extensive roofing jobs.
- Potential for Nail Jamming (Rare): In some cases, if a strip bends or a nail is slightly out of alignment, it can cause a jam, though this is usually easily cleared.
- Less Than Ideal for Repetitive Driving: While good for precise placement, they can be less efficient for the sheer volume of nails needed on a full roof replacement.

Choosing the Right Nailer for Your Project
So, how do you make the final decision? It really boils down to the job at hand. Here’s a simple breakdown to guide you:
When to Choose a Coil Roofing Nailer:
- You’re re-shingling an entire house or a large commercial building. The sheer speed and fewer reloads will save you hours.
- You have a large, open roof section with few obstructions. This is where the coil nailer’s rapid-fire capability will be most beneficial.
- Efficiency and speed are your top priorities. If you’re on a tight schedule or looking to get the job done as quickly as possible, the coil nailer is king.
- You’re comfortable with a slightly larger tool and plan to use it for extended periods.
When to Choose a Strip Roofing Nailer:
- You’re working on a small shed, a garage, or a porch roof. The number of nails needed is manageable, and the ease of handling might be preferred.
- You’re performing roof repairs or replacing a few damaged shingles. Precision and access to tight spots are more important than sheer speed.
- Your roof has a lot of complex angles, dormers, valleys, or other features that require you to work in tight or awkward positions.
- Weight and comfort are paramount, and you’re willing to reload slightly more often for a more agile tool.
- You might already own a strip nailer for other framing or finishing tasks, and its nail size might be compatible with some roofing nails.
Essential Features to Look For
Regardless of whether you lean towards a coil or a strip nailer, there are some universal features that make any roofing nailer a better tool. Keep these in mind when browsing:
- Adjustable Depth of Drive: This is crucial for setting nails perfectly. You want to be able to fine-tune how deep the nail goes to avoid damaging shingles or leaving them too proud. A tool-less adjustment is a big plus.
- Contact-Tipped Safety Mechanism: This prevents the nailer from firing unless it’s pressed against the roof surface, greatly improving safety.
- Lightweight and Ergonomic Design: Even with a coil nailer, comfort matters. Look for good grip materials and a well-balanced tool.
- Durable Construction: Roofing nailers take a beating. Steel or high-impact polymer construction will ensure longevity.
- Nail Jam Clearance: Easy-to-access mechanisms for clearing jams can save you a lot of frustration.
- Air Pressure/Tool Compatibility: Most roofing nailers are pneumatic. Ensure your air compressor can provide the necessary PSI (pounds per square inch) and CFM (cubic feet per minute) for the nailer. It’s good to have a compressor that can keep up with the continuous use demands of roofing. For an idea of compressor requirements, check out resources like The U.S. Department of Energy’s guidelines on building systems, which indirectly touch upon the efficiency of pneumatic tools and their power needs.
- Rain/Nuisance Trigger (Optional but helpful): Some higher-end models offer a trigger that can be locked in a “tool safe” position, preventing accidental firing when you’re simply repositioning the tool.
Safety First! Always
Using any power tool, especially a nail gun, requires a commitment to safety. Roofing work itself involves heights and potential hazards, so layering on tool safety is paramount. Here are the absolute must-dos:
- Always wear safety glasses: This is non-negotiable. Flying debris or nail fragments can cause serious eye injury.
- Wear hearing protection: Nail guns are loud! Protect your hearing for the long haul.
- Use sturdy footwear: Good grip on your shoes is essential for stability on the roof.
- Understand your tool’s safety features: Know how the contact tip, trigger lockout, and other safety mechanisms work.
- Never point the nailer at yourself or others: Treat it with respect.
- Keep fingers away from the firing mechanism and the nose of the tool when not actively nailing.
- Ensure the nailer is disconnected from the air supply when not in use, when changing nails, or when performing maintenance.
- Be aware of your surroundings: Ensure no one is below where you are working.
For more detailed safety information, always refer to the owner’s manual for your specific nailer and consult resources from organizations like the Occupational Safety and Health Administration (OSHA), which provides extensive guidelines for safe tool operation and construction site safety.
Frequently Asked Questions (FAQ)
Q1: Can I use a roofing nailer for other projects?
A: While some smaller roofing nailers might be adapted for certain types of siding or other exterior applications, they are highly specialized. Their long nails and specific collation systems are designed for roofing shingles, and using them for other tasks might not yield good results and could even be unsafe or damage the tool. It’s best to use the right tool for the job.
Q2: What kind of air compressor do I need?
A: Most pneumatic roofing nailers require a compressor that can deliver at least 4 CFM (Cubic Feet per Minute) at 90 PSI (Pounds per Square Inch). It’s always best to check your nailer’s specifications. A compressor with a slightly higher output than the minimum requirement will perform better and last longer, as it won’t be constantly working at its maximum capacity.
Q3: How many nails does it take to roof a typical house?
A: This can vary greatly depending on the type of shingles, the pitch of the roof, and local building codes. However, a general estimate is that it takes anywhere from 200 to 400 nails per roofing square (100 square feet). For an average-sized home, you might use 1,000 to 2,000 nails or more. This highlights why the high capacity of coil nailers is so beneficial for large jobs.
Q4: What’s the difference in nail size between coil and strip roofing nailers?
A: Roofing nails typically come in 1-inch to 1-1/4 inch lengths, with a specific diameter designed to penetrate the shingle and at least 3/4-inch into the roof decking. The collation method (coil vs. strip) doesn’t change the fundamental nail size; it only refers to how they are bundled for the tool.
Q5: Are there electric roofing nailers?
A: While there are electric nail guns for framing and finishing, dedicated electric roofing nailers are rare. The high power demand and continuous use of roofing applications generally make pneumatic (air-powered) nailers the standard and most practical choice due to their power-to-weight ratio and reliability.
Q6: Can I use non-collated roofing nails?
A: No. Roofing nailers, whether coil or strip, are designed to use specific types of collated nails. They rely on the collation (the wire or plastic binding) to feed the nails into the firing chamber correctly. Using bulk or non-collated nails would prevent the tool from functioning and could damage it.
Maintenance Tips for Your Roofing Nailer
To ensure your roofing nailer performs reliably and lasts for many projects to come, a little maintenance goes a long way. Here are a few simple tips:
- Lubrication: Most pneumatic nailers require a few drops of specialized pneumatic tool oil in the air inlet before each use. Check your manual for the correct type and amount.
- Cleanliness: Keep the tool clean, especially the magazine and firing head. Dust and debris can cause jams. Wipe it down after each use.
