Using a cat's paw nail puller

A cat's paw nail puller is a round or hexagonal steel tool that curves at one end to form a pointed, cup-shaped tip with a V-slot for gripping nail heads. It is a valuable tool for demolition work but is not suitable for finish work because 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 a small amount. Pound the pointed jaws of the cat's paw under the head; the force of a hammer is usually enough to do this. Once the head has been raised, slip a small piece of wood under the cat's paw for leverage, and then pry. The nail should pop out.

The cat's paw nail puller is a useful tool for removing tin roof nails, but it may not always be effective. In some cases, the nails are buried into the wood, making it difficult for the cat's paw to access the nail head. In such situations, you may need to use a different tool, such as a small pry bar, a flat bar, or an angle grinder, to lift the nail head before using the cat's paw to pull it out.

It is important to prioritise safety when using any tools, including the cat's paw nail puller. Always wear appropriate protective gear, such as gloves and eye protection, to safeguard against potential hazards like sharp metal edges and flying debris. Additionally, ensure that you have a firm footing and stable positioning before attempting to remove nails from a roof.

Cutting the nail heads off with bolt cutters

Removing nails from a tin roof can be a tedious and challenging task. One effective approach is to use bolt cutters to cut off the nail heads, allowing you to detach the roofing panels without causing significant damage. Here's a detailed guide on how to tackle this project:

Prepare the Necessary Tools and Safety Gear:

Before starting, ensure you have a pair of bolt cutters that are suitable for the job. The bolt cutters should be strong and durable enough to handle the nail size. Additionally, it is crucial to prioritize your safety. Wear protective gear, including gloves and safety goggles, to shield your hands and eyes from any debris or sharp fragments.

Gain Access to the Roof:

Safely climb onto the roof using a sturdy ladder. Position the ladder securely against the side of the building, ensuring it is firmly anchored to provide a stable platform during your work.

Cut the Nail Heads with Bolt Cutters:

Locate the nails holding the tin roofing panels in place. Position the bolt cutters firmly around the nail head, grasping it securely. Apply controlled force to cut through the nail head. Repeat this process for each nail, ensuring a clean cut every time.

Remove the Roofing Panels:

Once all the nail heads have been cut, you can begin removing the roofing panels. Carefully lift and flip each panel, starting from the peak of the roof and working your way down. Place the panels on the ground, taking care not to damage them if they are intended for reuse.

Handle the Remaining Nail Stubs:

After removing the roofing panels, you will be left with the nail stubs protruding from the roof deck. You can pull out these stubs using appropriate tools such as a pry bar or pliers. If necessary, use a hammer to drive the nail stubs below the surface, being cautious not to damage the underlying structure.

Safety Precautions:

Throughout the process, maintain a safe working environment. Avoid hitting two hammer heads together, as it can be dangerous and cause injury. Additionally, be cautious when drilling or cutting to prevent metal shards from flying off and causing harm.

By following these steps and taking the necessary safety precautions, you can effectively remove tin roof nails by cutting the nail heads off with bolt cutters. Remember to work methodically and patiently, ensuring the job is done right to avoid any potential issues or accidents.

Using a slide hammer nail puller

The slide hammer nail puller is designed to exert force without relying on leverage, which distinguishes it from traditional nail pullers. This unique mechanism allows users to remove nails with one or two forceful strikes of the weight, saving time and effort.

To use a slide hammer nail puller, start by positioning the tool's jaws securely around the nail head. Ensure that the jaws have a firm grip on the nail to prevent slippage during the extraction process. Once the nail puller is in place, forcefully slide or pull the hammer component away from the nail, creating a sudden impact that dislodges the nail from the roof.

The force generated by the slide hammer action effectively breaks the seal or bond between the nail and the metal roofing, allowing for efficient nail removal. This method is particularly advantageous when working with corrugated metal roofs or panels where access to nail heads may be limited.

Additionally, the slide hammer nail puller can be adapted for specific needs. Some users have modified their slide hammers by welding hoof nippers or adapting a cat's paw nail puller head, enhancing their ability to grip and extract nails without causing damage to the surrounding metal. These adaptations underscore the versatility of the slide hammer nail puller and its effectiveness in removing tin roof nails.

Using a small grinder to grind off the nail heads

To use a small grinder effectively to remove tin roof nails, follow these steps:

  • Wear the appropriate safety gear, including a face shield and gloves, as the grinding process can create nasty chips and debris.
  • Choose the right grinder and cutting wheel. A carbide burr in a 1/4" grinder can be used to cut off the nail heads without raising them first. Alternatively, a 4" or 4 1/2" grinder with a metal cutting wheel (not a grinding wheel) can be used for a flush cut.
  • Build a steady rhythm when grinding. With practice, each nail should take around 2-3 seconds to grind off.
  • Apply an oil primer to the ground nails to protect the surface and maintain its appearance.

While using a small grinder can be an effective method for removing tin roof nails, it is important to prioritize safety and surface protection throughout the process.

Using a slate ripper to hook the nail and remove it

Using a slate ripper to remove tin roof nails is a straightforward process. First, you need to identify the piece of slate that needs to be removed and slide the ripper underneath it. A good slate ripper, like the Stortz ripper, will have a spring to the blade, providing the flexibility needed when sliding it under the slate. Once the ripper is in position, you can start to remove the nails. The ears of the ripper are designed to hook onto the roofing nails, and by applying gentle downward pressure on the handle and using a hammer to strike gently on the upright of the ripper, you can pull the nails out. It may take multiple light strikes to cut or pull the nail, but this is preferable to heavy blows, which could damage the slates.

If you are having trouble catching the nail with the hook, you can try using the front edge of the blade. Gently hammer the ripper upwards and apply gentle pressure to the slate, sandwiching it between your hand and the blade of the slate ripper. With a bit of wiggling, the slate should come free without too much difficulty. Once all the nails have been removed, you can gently nudge the slate from its position, using the slate ripper placed beneath the slate and your palm on top.

When removing and replacing slates, it is important to keep an eye out for any cracks, as these can let rainwater seep through, even if they are beneath other slates. It is also important to note that slates are ordered by size, usually in inches, with the length given first, followed by the width. A typical example is an 18 x 9 slate, which is 18 inches long and 9 inches wide. If you cannot get the right size, you can cut down larger slates, but never use smaller ones. When placing a new slate, the top edge should rest halfway onto the top batten, and the nail holes should be positioned so that the nails will enter the middle batten just above the top edge of the row of slates below. Remember not to hammer the nails down too tight, as this will allow for expansion and contraction with the seasons.

Finally, when using a slate ripper, or any roofing tool, it is important to prioritize safety. The SLATOR (Secure Ladder And Tie Off Responsibly) is a product that provides roofers with simple and safe access to slate roofs. It is screwed into the roof rafters and a ladder is firmly clamped into it, providing fall protection for workers.
