If you're doing any kind of work regarding a metal roof on your property, whether it's installing new metal roofing panels, adding additional fastening to existing panels or any other task, the use of metal roofing screws and related fasteners is important. The tools you use to drive these screws into panels or other metal roofing components are also key considerations, and two common examples that are often compared with one another here are impact drivers and drill drivers.
At Supply Maverick, a division of Mid Michigan Metal Sales, we're proud to offer an extensive range of metal roofing fasteners, including metal roofing screws of numerous varieties to meet your every possible need. We also offer simple expertise and recommendations on how to utilize our products, such as recommending the ideal tools for any metal roofing screw application. What are impact drivers and drill drivers, and what are the pros and cons of each for use with metal roofing screws? Let's take a look.
Impact Drivers
For those just learning about them, an impact driver refers to a powerful tool that uses both rotational and concussive force to drive screws into hard materials like metal. Unlike drill drivers, impact drivers have an internal mechanism that creates a downward force when the tool's body hits a surface after each rotation. This added force results in increased torque and allows for easier driving of long or thick screws.
Pros
Impact drivers offer several key advantages, including:
- High force level: As mentioned, impact drivers provide more force than traditional drill drivers, which makes them ideal for heavy-duty work.
- Faster speed: Due to their unique mechanism, impact drivers can drive screws much faster than other tools. This means you can complete your projects in less time and with greater efficiency.
- Lightweight design: Impact drivers are compact and lightweight, making them easier to handle and maneuver compared to bulkier power tools like drills.
- Versatility: Impact drivers come with interchangeable bits that allow you to use them for a variety of tasks beyond just driving screws. You can also use them for drilling holes or removing rusted bolts.
Cons
While impact drivers offer many benefits, they also have some limitations to keep in mind:
- Possible force-related damage: Likely the largest possible downside to impact drivers for use on metal roofs is the potential for damage due to excessive force. If you are not careful, it is possible to overdrive screws and cause them to penetrate too deeply into the metal panels, which can lead to leaks and other issues. For this reason, any use of impact drivers for metal roofing screws must involve care to ensure that the proper torque is set, and the user must be cautious to avoid using excessive pressure or speed when driving screws into place.
- Noise: As mentioned earlier, impact drivers can be quite loud due to their repetitive hammering action. This may not be a major concern for outdoor metal roofing projects, but it could present an issue for indoor use or in more populated areas where noise ordinances may apply.
- Possible screw damage: Again due to their force levels, it's possible to damage screws themselves if they are not correctly countersunk into the surface. This can result in stripped screw heads or damage to the material being fastened. Again, this requires careful attention to detail and force levels if you're using an impact driver on your metal roof.
Drill Drivers
More traditional drill drivers, which refer to both cordless and corded drill models, are also suitable for use on metal roofs. Here are some of their pros and cons:
Pros
- Safer and lower damage risks: Because they come with lower force than impact drivers and do not create downward force (they use only rotational force), the chances of damaging your roof or its material are much lower.
- More control: With drill drivers, you can adjust the speed and torque to better suit your needs and avoid overdriving screws, which is especially important for thinner metal roofs.
- Less slipping: The chuck on a drill driver is less likely to slip, meaning you won't have to constantly adjust and re-secure your bits.
- Versatility: Drill drivers can also be used for other tasks such as drilling holes in metal or wood, making them a more versatile tool to have in your toolbox.
- Less expensive: Compared to impact drivers, drill drivers are generally less expensive, making them a more budget-friendly option for those who don't need the extra power of an impact driver.
- Quieter operation: The rotational force of drill drivers creates less noise compared to the high impacts of an impact driver, making them a better choice for those working in residential areas with noise restrictions.
Cons
At the same time, drill drivers have some possible downsides:
- Less powerful: Compared to impact drivers, drill drivers are generally less powerful and may struggle with tougher materials or larger screws. This can result in slower work progress and potentially more strain on the tool.
- Lacks impact feature: While drill drivers are versatile tools, they do not have the same impact feature that allows an impact driver to generate high levels of torque, making them less suitable for heavy-duty tasks such as driving large bolts into concrete or metal.
- Less strength in connection: Because of the lower torque and impact feature, drill drivers may not have the necessary strength to maintain a secure connection with a screw or bolt. This can lead to stripped screws or bolts that are not properly tightened.
Ultimately, both impact drivers and drill drivers can be used for metal roofing screws - with the proper approaches and precautions.
