If you work in the U.S. roofing industry or around this location, an old question always arises – can you use staples on roof shingles? Or nailing or stapling, which is better for roofing shingles?
In the mid-to-late 20th century, staples were a go-to choice for many roofers. Stapling on roof shingles might be an easy solution for roofing, but not the most effective way to install shingles.
Nowadays, experts’ opinion is not to use staples in raw roof shingle installation projects. though it is not recommended, you might use them in some situations like roof underlayment.
Why Staples Were Once Popular for Roofing
Stapling roof shingles was a popular method for roof contractors not just because they were cheap and easy to use, but also because staplers offered a level of speed and convenience than that time of nail guns or nails.
However, as time went on, issues with durability and performance under extreme weather conditions began to emerge. Nowadays, stapling is considered as an inferior method of attaching roof shingles commercially as well as residentially.
Here, we can find some key reasons to understand why roofers would like staples:
- Staple guns are smaller and better balanced.
- The coil roofing nail guns literally have a coil of nails, that makes the gun much heavier.
- Staples are less prone to jamming up in a staple gun than nails.
- Staples are less expensive than roofing nailer guns.
- Staples are much more compact and easy to handle.
- A roof shingle installer can take a bunch of sticks of staples in their pocket, which he can’t do in the case of roofing nails.
- Nails take enough time to reload, whereas staples don’t take much time to reload.
- Roofing nail guns require proper maintenance and lubrication. But staples don’t need that much maintenance and lubrication like roofing nailers.
- Contractors could cover large areas quickly.
- The wider crown of a staple created more surface contact with the roof shingles, which initially seemed like a better idea for securing the materials.
Can You Use Staples on Roof Shingles Today?
Staples were once commonly used to fasten roof shingles, but they are no longer widely accepted in most modern roofing practices.
Using staples on roof shingles is technically possible, but it’s generally not recommended today.
One major issue with stapled shingles is their higher risk of coming loose or being blown off the roof.
This happens because staples are often installed incorrectly, making them less secure. Moreover, staples don’t provide the same holding power as roofing nails.
The problem largely stems from how a staple gun is used during installation. When fastening shingles, it can be tricky to position the staple gun at the correct angle.
For right-handed roofers, for example, it’s much easier to shoot staples on the left side of their body at a forward slash angle (\) and on the right side at a backward slash angle (/).
This small tilt in staple placement might seem minor, but it weakens the shingles’ hold.
Since keeping the staple gun at the right angle can be tricky, staples often end up misaligned, which can make the shingles more prone to damage from weather and wind over time.
The suitability of staples largely depends on the specific context. For example, if you’re working on a temporary repair or a small shed in extreme weather conditions, staples might be a viable option.
Additionally, regions with milder climates, where wind and rain are less intense, might allow staples to perform adequately.
In contrast, for critical structures or areas prone to storms, nails are generally the better and more reliable choice. Therefore, understanding the unique demands of your project is key to making the right decision.
In today’s world, Most roof shingle manufacturers and building code regulators recommend using nails over staples.
Due to the strong holding power of nails, which are better equipped to withstand high winds and other harsh weather conditions.
Here are some key reasons why staples are not recommended today for roof shingles installation:
Building Codes & Regulations
Building codes in many regions have been updated to assure modern roofing standards. Many building codes now prohibit the use of staples for roofing shingles.
Nails are used because of strong holding power and reduction of tear of shingles in high winds.
However, there are still some locations where staples are allowed. You can use them, particularly for temporary fixes or in regions with milder weather conditions.
Manufacturer Guidelines
Many branded manufacturers clearly state in their warranty documentation that staples should not be used.
Most shingle manufacturers want the use of nails to comply with their warranty conditions. They explicitly state that, If you staple shingles and later experience any issues, you might not get the warranty facilities.
It means you will be financially responsible for any repairs.
Regional Variations
In some regions of the world, staples are still a common choice due to their cost-effectiveness and availability.
But in these areas, the trend is moving toward nails replacing the use of staples. It means nails will be preferred as a main fastener for long term reliability.
Durability Concerns
Staples are more prone to loosening over time or during severe weather, which can lead to shingle damage or loss. Moreover, staples don’t deliver strong holding power to ensure longevity.
Wind Resistance
Modern roofing standards emphasize wind resistance in the case of installing roof shingles both commercially and residentially.
Generally, nails are more secure than staples, and nails outperform staples in this area.
When to Use Staples Instead of Nails?
Staples may be used instead of nails in certain situations like temporary fixing, non-critical applications, or if you don’t have a roofing nail gun.
However, you have to follow some important considerations such as ensuring building codes, manufacturer warranties, and wind or weather conditions.
Though staples are not recommended now for roof shingles, you may apply them in some cases:
Temporary Fixes
You can use staples if you just need some temporary fixes like small repairs or emergency roofing solutions.
But I would say to ensure a roofing nailer gun in case of emergency. Therefore, storing a roofing nail gun in your nail gun storage place would be a wise decision.
Non-Critical Applications
You can apply staples in case of some non-critical uses such as lightweight insulation or roof underlayment.
Staples are sometimes used to attach lightweight materials like roof underlayment, house wraps, or insulation that don’t need the strong holding power that comes from nails.
Light duty Roofing Materials
In low wind areas, you can use staples for lightweight roofing materials like cedar shingles or shakes. However, in these cases, staples might be permitted in some regions, but this is rare today.
Pros & Cons of Staples for Roofing
Though we know that, staples are not recommended in this modern era of roofing. However, I tried to showcase some advantages and disadvantages of installing roofing shingles through staples.
Pros
Easy to Maneuver
Staples or staple guns are less bulky and light weight. Therefore, they are easier to control than heavy weight and bulkier roofing nail guns.

Poor Staples Placement
Incorrect staple placement on shingles can compromise the roof’s strength. It takes precision and expertise to ensure staples are properly inserted and stand upright in each shingle.
Less Holding Power
Staples aren’t as reliable for securing shingles, especially in windy areas, as they tend to lose their grip over time. In these conditions, staples are more likely to come loose or be blown off.
Don’t meet Building Codes
Stapling roof shingles often don’t comply with local building codes. In many areas, using staples for roofing can lead to your repair or replacement failing inspection, as it doesn’t meet the required standards.
Often Installed Improperly
It can be challenging to keep a roofing staple gun straight when securing shingles. This inaccuracy may cause the staple to be driven in at an angle, which doesn’t hold the shingle properly.
Limited Applications
Staples may not be the best choice for all types of roofing materials, especially heavier shingles or tiles, which need more durability.
Risk of Over Penetration
If staples are driven too deep into roofing materials, they can create punctures or damage, which can weaken the roof’s structure.
Inconsistent Hold in Windy Areas
In areas with strong winds, staples may not be as reliable as nails, which are often a better choice for keeping roofing materials securely in place.

FAQs
1. What size staples are best for shingles?
Ans: Staples for shingles are usually 1 to 1 1/2 inches long, depending on the thickness of the shingles. A crown width of at least 7/16 inches is recommended to ensure they hold securely.
However, it’s crucial to review local building codes and the shingle manufacturer’s guidelines.
2. Is it OK to use staples for roof underlayment?
Ans: While staples can technically be used for roof underlayment, nails are generally a more reliable choice because they provide a stronger and more secure attachment.
3. How to attach shingles without nails?
Ans: While it’s not ideal to attach shingles without nails. As nails offer the strongest and most reliable hold, alternatives like roofing adhesive or heavy-duty roofing tape can be used in certain situations.
Keep in mind that these options tend to be less durable and may not stand up to high winds as well as nails do.
4. What are the best fasteners for asphalt shingles?
Ans: The best fasteners for asphalt shingles are usually galvanized or stainless steel nails, as these materials resist rust and corrosion, ensuring the roof’s durability over time.
These nails should have a large, flat head to properly secure the shingles and prevent them from lifting. Nails ranging from 1 1/4-inch to 1 1/2-inch in length work well, depending on the thickness of the shingles.
5. Is it okay to screw into roof shingles?
Ans: While it’s possible to use screws to attach roof shingles, it’s not the most effective method. Screws can create small spaces around the shaft, which could cause water penetration and leaks or damage over time.
Moreover, screws don’t hold shingles as securely as roofing nails, which are designed specifically for this purpose.
6. Will staples damage shingles?
Ans: Staples can cause damage to shingles if they’re not installed properly. If they’re driven in too deep, they can create holes in the shingles, which might allow water to seep through and lead to leaks.
