Removing roofing nails can be a tedious and challenging task, but with the right tools and techniques, it can be done efficiently. When dealing with lead roofing nails, it is important to consider the condition of the nails and the roof. Over time, roofing nails can loosen, rust, or fail, requiring replacement to maintain the integrity of the roof. The process typically involves accessing the roof safely, locating the nail heads, using tools such as a cat's paw pry bar or a hammer and a block of wood for leverage, removing the nails, addressing any rust or damage, and finally, replacing the nails or using roofing screws to secure the roofing material.

What You'll Learn
Using a cat's paw to pry out the nail
A cat's paw is a valuable tool for removing roofing nails. It 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. The pointed end of the cat's paw is placed under the nail head, and a hammer is used to drive the claw around the nail head. This raises the nail head, and a small piece of wood can then be slipped under the cat's paw for leverage to pry out the nail.
The cat's paw is a useful tool for this task as it can grip the nail head in multiple locations and angles, allowing for ease of access in tight spaces. It is also a useful tool for demolition work, although it can tear up the wood around the nail head, so it is not suitable for finish work.
To remove roofing nails, it is important to start at the peak of the roof and work your way down. This ensures that you are not standing on the roof panels when they are no longer secured to the roof deck. For safety, when removing the last few nails, you should stand on a ladder that is firmly anchored to the side of the building.
The cat's paw is a popular tool for roofing, carpentry, and construction. It is a staple in many professionals' tool collections and is also useful for DIY enthusiasts. The tool is praised for its design, quality, and functionality, with many users finding it comfortable and easy to use.

Removing rust and applying primer
When removing lead roofing nails, it is important to take precautions to prevent rusting nails, as rusted nails can weaken and cause leaks and damage to your home. To remove lead roofing nails, start by pressing down on the roof slightly to expose the nail. Then, use a good pair of vice grips or a slide hammer to remove the nail. Once the nail is removed, clean the area and remove any surface rust from the hole using a wire brush on a drill or an abrasive disk.
After removing the rust, it is important to apply a primer to the area. First, ensure that the surface is clean and dry, as any dirt or dust will compromise the bond. You can use a rust remover/primer, or a product like Killrust, to paint over the metal and any remaining rust. If you are using asphalt roofing, it is important to follow the manufacturer's recommendations, as asphalt roofs contain light oils that can leave the membrane soon after application. This process, called "tobacco juicing," will generally wash off after rainstorms, but it is crucial to thoroughly clean any exudate on the roof before applying the primer.
It is worth noting that primers are not a substitute for proper roof coating or membrane preparation. Surfaces that typically require a primer include concrete and masonry roof decks, gypsum, block, brick, parapet walls, and metal flashings. The type of primer used depends on the substrate, weather conditions, and the type of coating or membrane application. For example, only asphalt primers should be used with asphalt materials, and asphalt emulsion primers can be applied to damp surfaces.
After priming, you can screw in your roofing screw. It is recommended to use screws that are slightly longer than the nails and to ensure they bite into good wood. Additionally, be careful not to tighten the screws too much to avoid water getting stuck behind the washer.

Using roofing tar to patch holes
To remove lead roofing nails, you can press down on the roof slightly to expose the nail, then remove it with a good pair of vice grips. You can then reuse the same hole for a roofing screw. Alternatively, you can punch the nail out of the way and try to get a screw in as squarely as possible.
Roofing tar is a dark and oily substance primarily composed of petroleum byproducts and coal tar. It is used to repair leaks in commercial and residential roofs. When applying roofing tar, it is important to avoid doing so when it is raining or snowing, and it should be applied when the temperature is between 40 and 70 degrees. If it is too hot, the tar may drip and not seal properly.
To start, you need to find out how much tar you will need by measuring and calculating the dimensions of your roof. Asphalt tar is usually the best option, but if your roof has a steep slant with slopes and eaves, you may want to use coal tar bitumen. You can always take a picture of your roof and ask a professional at a hardware store if you are unsure.
Before applying the tar, you should create a base layer by nailing a coating onto your roof. This will serve as a buffer between the tar and your roof and prevent heat damage. The coating can be elastomeric, asphalt, or aluminized, depending on the weather and the shape of your roof. If you want extra layers, you can use a coating that is gravel-embedded.
When applying the tar, start in the corner of your roof and pour it out, using a fiberglass mop to move it around with smooth strokes. Cover every area of the roof, ensuring that your layers are thin. Work in straight lines towards the opposing corner, being careful that the tar does not build up or clump. Carefully spread tar paper across the top of the tar and use your mop to go over it, ensuring that it sinks into your asphalt. Seal each layer by overlapping the tar paper.
You can also use roofing tar to seal over roofing nails.

Using a broom handle to lever out nails
Removing lead roofing nails can be a tedious and physically demanding task. One way to do it is by using a broom handle to lever out the nails. Here's a step-by-step guide on how to do it:
First, cut about 100mm off the end of the broom handle. This will help it fit into the pan of the corrugation, which is the grooved pattern on the roofing material. Place the cut end of the broom handle into the corrugation next to the nail you want to remove. Make sure it lies flat and stable in the profile.
Now, use the broom handle as a lever to pry against and pull out the nails. You can apply pressure with your hands or even step on the broom handle to get more force. Be careful not to slip and maintain your balance on the roof. If the nails are stubborn and difficult to remove, you can use a hammer to loosen them. Place the head of the hammer over the head of the nail and strike it gently to loosen its grip.
If you're dealing with a large number of nails, this process can be time-consuming and tiring. Take breaks and stay hydrated, especially if you're working in hot weather. Remember to always prioritize your safety when working at heights. Wear appropriate protective gear, including gloves and eye protection, to prevent injuries from nails or sharp roofing materials.
Using a broom handle to lever out lead roofing nails is a practical and cost-effective method. It helps you avoid damaging the roofing material while providing leverage to remove the nails. With patience and caution, you can successfully remove lead roofing nails using this technique.

Using a slide hammer to remove nails
Removing lead roofing nails can be a challenging task, and one effective tool for the job is a slide hammer. This tool is particularly useful when dealing with ring shank sealing nails, as it can extract them without damaging the underlying metal.
First, you'll want to press down on the roof slightly to expose the nail head. This will give you a better grip and make it easier to work with the slide hammer. You can use a broom handle or a similar tool to press down on the roof gently without causing any damage.
Now, you're ready to use the slide hammer. Position the slide hammer's nail puller attachment directly over the nail head. Make sure it's securely in place and that the attachment is the correct size for the nail you're dealing with.
With the slide hammer in position, it's time to start extracting the nail. Grip the handle of the slide hammer firmly and pull back on it, using a smooth and controlled motion. The weight of the slide hammer will provide the force needed to pull out the nail. Depending on the nail's resistance, you may need to apply a bit of force or "slam" the slide hammer a couple of times to dislodge the nail effectively.
In some cases, you may need to twist the slide hammer slightly as you pull to break the nail's seal. This is particularly true for newer nails, which often have a twist in the shaft. By combining a pulling and twisting motion, you can ensure the nail comes out cleanly.
Finally, once the nail is removed, take the necessary steps to prepare the area for a roofing screw. This includes cleaning the area, removing any surface rust, and treating the area with a rust converter or primer to prevent further corrosion. You can then screw down using a roofing screw, preferably one that's a bit longer than the nail you removed.
Using a slide hammer is an efficient way to remove roofing nails, especially when dealing with metal roofs. It's important to work carefully and follow the necessary safety precautions when working on a roof, but with the right tools and techniques, you can effectively extract those stubborn nails.
