What You'll Learn
Use a cat's paw nail puller
A cat's paw nail puller is a round or hexagonal steel tool with a pointed, cup-shaped tip and a V-slot for gripping nail heads. It is a valuable tool for demolition work but is not suitable for finish work as it tends to tear up the wood around the nail head.
To use a cat's paw nail puller, you first need to raise the nail head slightly. You can do this by pounding the pointed jaws of the cat's paw under the head with a hammer. When the V-slot is firmly seated around the nail's shank, rock the bar back to raise the head further, then finish pulling the nail with the hammer's claw.
If the nail head pops off, you can drive the claws of the cat's paw through the old metal to lift it off the nail. Using a block of wood under the hammer can give you better leverage and help protect the roof from damage.
While a cat's paw nail puller can be an effective tool for removing nails from a tin roof, it may not always work, especially with larger nails. In some cases, the nail heads may be pulled off, leaving the nail shafts still embedded in the roof. In such cases, you may need to use a different tool, such as a slide hammer nail puller or a small grinder to remove the remaining nail shafts.

Use a straight-claw hammer
Removing nails from a tin roof requires careful execution to prevent damage to the roof. One of the tools that can be used for this purpose is a straight-claw hammer. Here is a step-by-step guide on how to use a straight-claw hammer to remove nails from a tin roof:
First, place the claw securely around the nail you want to pull. Ensure that the head of the nail is visible on the side of the claw facing you, and the neck of the nail is positioned between the bars of the claw. It is important to use the proper tools and techniques to avoid damage to the roof, especially if it is made of soft metal like aluminum.
Next, use a 2x4 wood block to lever the hammer against. Place the wood block under the fulcrum point of the hammer. This point of the hammer will exert pressure against the levering surface when the nail is pulled from the roofing. The block will not only absorb the pressure to minimize damage to the surrounding metal but also provide a solid surface to lever against.
Now, lever the hammer by pulling the handle toward you, maintaining firm pressure against the wood block. For longer nails, you may need to apply downward pressure on the end of the hammer. Keep pulling until the nail breaks free of the metal.
If the straight-claw hammer is not effective in removing the nails, there are alternative tools and techniques you can consider. For example, you could use a "cat's paw" nail puller, a pry bar, or a small grinder to grind off the nail heads. Additionally, you might try sharpening the claws on an old rip hammer and then using another hammer to drive the claws under the nail head, allowing them to bite into the shank of the nail.
Remember to prioritize safety and caution when working on a roof. Always start at the highest point of the roof and work your way down. If removing nails near the edge, use a ladder rather than stepping on the roof itself to avoid damage and ensure your safety.

Work from the highest point down
Working from the highest point down is a key principle when removing nails from a tin roof. This is because, once all the nails are removed, the roof panel will no longer be attached to the roof deck and will simply slide off. Therefore, you don't want to be standing on the roof when the last few nails are removed.
When removing nails from a tin roof, it's important to start at the peak of the roof and work your way down. If you are removing all the nails from the roof, you need to ensure that the roof remains firmly in place in the areas where you will be standing. Loose roofing can give way under your feet, so caution is required at all times when walking on it. When removing the final nails, you should be standing on a ladder that is firmly anchored to the side of the building, rather than on the roof itself.
If you are removing nails near the edge of the roof, it's best to pull the nails while standing on a ladder, rather than stepping onto the roof. Only walk or stand on the portions of the roof that still have nails in place.
If you are removing nails from a soft metal roof, such as aluminium, take extra care as it can be easily dented or damaged.

Use a nail jack or crescent puller
Removing nails from a tin roof can be a tedious and challenging procedure. Walking on the roof can cause damage to the surface, so caution must be exercised at all times. If you are removing nails near the edge of the roof, it is advisable to stand on a ladder rather than on the roof itself.
One effective tool for removing nails from a tin roof is a nail jack or crescent puller. This tool has a unique design with a beak that fits over the nail head. To use the nail jack or crescent puller, place the beak over the head of the nail. For nails set into the wood, you may need to hit the tool a couple of times to get under the head. However, for nails with washers, you can usually grab the head directly. Once the beak is securely in place, simply rock the tool to loosen the nail.
It is important to hold the nail jack or crescent puller properly to avoid any injuries. If you don't hold it correctly, you may end up with a blood blister when you thump the tool. Additionally, make sure to start with the nails at the highest point of the roof and work your way down. This will help ensure that you don't stand on loose roofing, which can give way under your feet.
The nail jack or crescent puller is a highly efficient tool for removing nails from a tin roof. According to a user, it is even faster and creates less damage compared to other tools such as various types of "paw" or "hoof" pullers and crowbars. With its unique design and functionality, the nail jack or crescent puller can effectively remove even tough nails like ring shanks.

Protect the roof with a block of wood
Protecting your roof with a block of wood is an important step in the process of removing nails from a tin roof. Here are some detailed instructions to guide you through the process effectively:
Firstly, it is important to understand the purpose of using a block of wood. When removing nails, especially from a tin roof, it is crucial to minimise damage to the surrounding metal. A block of wood provides a solid surface to lever against while also absorbing the pressure exerted by the tools used for nail removal. This helps to protect the roof from dents or other types of damage.
The recommended type of wood to use is a 2x4 wood block. Place this block of wood under the fulcrum point of the tool you are using for nail removal, such as a hammer or flat bar. The fulcrum point is where the tool will exert pressure against the levering surface when you pull out the nail. By placing the wood block at this specific point, you can effectively distribute the force and protect the roof.
When using a hammer or flat bar, position it securely around the nail you want to pull. Ensure that the head of the nail is visible on the side of the tool's claw that faces you, and the neck of the nail is positioned between the bars of the claw. With the tool in place, you can now leverage its handle towards you, maintaining firm pressure against the wood block. For longer nails, apply downward pressure on the end of the hammer or flat bar.
If you are using a "cat's paw" nail puller, you may need to pound its pointed jaws under the head of the nail. A clay hammer is often used for this purpose. The force of the hammer should be sufficient to raise the nail head slightly, making it easier to grip and pull out. Alternatively, you can sharpen the claws of an old rip hammer and use it to drive the claws under the nail head, allowing them to bite into the shank of the nail.
Always remember to exercise caution when walking on a tin roof during the nail removal process. Start at the highest point of the roof and work your way downward. If you are removing nails near the edge, use a ladder to pull them out instead of stepping directly on the roof to avoid causing unnecessary damage. By following these steps and utilising a block of wood for protection, you can effectively remove nails from a tin roof while minimising potential damage.
