Why Do You Need a Roofing Knife?

Stanley 0-10-819 Snap Off roofing knife

Believe it or not, a safety hazard can easily lurk if a roofer is using roofing tools not specifically designed for that roofing task. Thus, one of the essential ways to decrease the probability of an injury is to use the tools made only for that specific task. It also boosts the roofer’s efficiency.

Consider this scenario: For installing 3-tab shingles, it is essential to cut them into sections for getting ridge and hip shingles. Regardless of the shingle in use, it is also important to cut a roof underlayment.

For these requirements, a standard utility knife is an okay option. However, as a specialized utility knife, a roofing knife tends to fulfill these requirements more easily and comfortably. This is because it has a roofing blade with a dedicated hook close to its edge’s tip that enables controlling the cut while dealing with thicker materials such as shingles. A hook blade is better than a straight one, as it does not damage the material’s surface being cut.

A hooked or an angled roofing knife is the only tool that helps reach the spots where a straight-handled blade cannot reach. Further, its design is such that it is easier on the hands while using it for an extended period.

Shrewd and professional roofers prefer a roofing knife that is versatile and ensures precision. The advanced models are usually retractable and work beyond cutting shingles. In addition, you can open and close it using one hand, ensuring safety when in an off-balance position.

A few models come with a replaceable blade and its release button so that you can easily replace its dull blade. This means that you don’t need to change the entire knife but only the blade.

Types of Roofing Knife Blades

Roofing knives are classified into three categories as per their blades. While installing composition shingles, one of the following roofing blades is used:

  • Bowtie blade for handling cold shingles and thicker shingles with granules on both sides
  • Hook blade for handling warm shingles
  • Utility blade for handling (cutting) roofing felts, also known as tar papers, not for cutting shingles.

In short, for handling shingles, a hook or bowtie blade is fine. However, for cutting felts, a utility blade is required. Both bowtie and hook blades tend to feature a square hole. In the case of thin roofing felt, a utility blade is likely to be an apt tool.

However, in the case of thick roofing felt perhaps coated with sand, this blade fails quickly, breaks easily, and becomes dirty instantly. This is where the hook blade is used. As the name indicates, this blade has a hook, which is the sharp part of the blade and ensures more precise cutting. Nevertheless, some knack is required to use such a blade.

Salient Features of Roofing Knives

Retractable/Folding or Fixed

A roofing knife can either have a fixed or retractable/folding blade. While retracting is for DIY home users, a fixed one is for professional roofers as the blade is fully exposed. As the name indicates, a fixed-blade roofing knife has a blade in a fixed place to ensure more strength and durability than a folding blade.

You can easily access the firm blade with a single hand and expect more precise cuts. Fixed-blade models are costlier than the folding-blade ones but are made to last.

On the other hand, a folding blade is not made for constant use and is susceptible to snapping and bending. It fully resides in the handle for safe storage when not in use. Pulling the blade out and pushing it in can make you feel tedious, especially while making many movements while performing the task.

A folder is considered safer and more portable than a retractable knife. It is also smaller, has handy belt hooks, and is easier to store.

Considering how the blade resides in the handle, the probability of a folder accidentally deploying while in your pocket is quite less.

After being closed, a folder is usually two to four inches shorter than a retractable one, due to which it is a better option for a pocket on pants. It is also less susceptible to getting stuck.

A retractable knife either has a manual or automatic retraction. A manual retractable knife has a blade that pulls back into its handle. The blade has fixed positions for locking at the time of cutting.

Once the position is set, there is no need to use any mechanism to keep the cutting area exposed. This removes the risk of hand strain, ideal for repeated cuttings. On the flip side, the risk looms if the blade is not fully retracted after use.

On the other hand, an automatic retraction involves the typical spring-loaded mechanism demanding you to use a trigger such as a slider or a button to open the blade. It is safer than manual retraction as there is no chance of leaving the blade accidentally exposed.

Choosing a fixed or folder/retractable is a matter of your preference and how you wish to do your task. A folder is fine only for occasional use. It is smaller and more portable than a fixed-blade knife.

Good Grip

Regardless of what you are doing, the best roofing knife needs to ensure a good grip. The most reliable models will have a finger groove that acts as a hurdle to slippage to fulfill this purpose. It has nothing to do with hand strength.

This does not mean that a light grip is fine, but your hands are less likely to slip when the fingers are even hooked a bit into the tool. Some roofing knives do not use a groove but rather ensure grip with a curved handle, textured handle, or finger ridge area.

However, the finger groove seems to be the most effective option for grip. A finger-friendly handle features a profound groove or notch to keep the risk of slipping toward the blade at bay while cutting shingles or felts. It also has a comfortable grip to prevent your hand from sliding while hauling tough materials.

Single-handed Opening

A folding roofing knife usually allows you to open or close its blade using just one hand. This is an important feature, especially if you use the tool all day long. You then no longer need to open and close the blade repeatedly, which would otherwise become tiresome.

Moreover, you are already holding the shingle or felt to cut with one of the hands. Thus, using the other hand for opening or closing the blade is convenient. These roofing knives usually have a blade lock that opens or closes the blade by pushing a button. Just ensure that the locking mechanism is strong for safely covering the blade when not in use.

Plastic or Metal Construction

Roofing knives are made using either plastic or metal. However, a plastic knife will be unable to endure constant use. Thus, it will not last long. This is why a roofing knife with a metal body is preferable.

Replaceable Blade

Most roofing knives will come with a replaceable blade. For replacing the blade, it is essential to ensure that the knife has a simple design and keeps your hands far from the edge.

In short, it is better to choose a model having fewer moving parts. Most modern utility knives allow changing their blades via a finger release or thumbscrew. This means that there is no need for a screwdriver once the blade becomes dull.

Blade Storage

This is not an essential feature but a convenient one for DIY users. It is wise to have a roofing knife with a blade storage utility for storing additional blades. For a pro, this is a crucial feature.

This is because, for them, it is common to use three or four blades while on the site. Having some spare ones on hand saves both energy and time looking for them. Even for the home users, having an extra blade helps for some tasks that may come up, such as scraping a small paint splotch. Roofing knives with the storage facility demand a few dollars more, but it is okay to have it as long as it does not give you a bulky feel.

Optional Features

Some roofing knives may also come with a wire stripper, strong cutter, gut hook for making instant cuts without opening the blade, belt or pocket clip for quick access from toolbelt, lanyard hole for hanging the knife from the belt, and specialty blades for handling different shingle materials. You may not find all of them in one knife. So, choose the knife with one or more of these features, provided they are useful to you.


Can I sharpen a roofing knife?

Yes, you can. However, you will have to go through the manufacturer’s manual to know how to do so. Also, depending on the blade, the sharpening technique or tool is likely to change. For example, a hook blade needs water, ceramic, or diamond abrasive.

How to use a hook knife to cut the extreme edge of the roof in a straight line?

Place the hook knife’s side against the gutter edge beneath the shingle such that the blade is upward. Then, by applying upward pressure, move the knife towards you. Now, bow the shingle from atop and break it off. Perform this procedure after setting every row of shingles.

What care should I take while cutting shingles so that my roofing knife blade does not become dull?

If you cut shingles from their granulated side, the blade of your roofing knife will dull swiftly. Instead, consider cutting shingles from their rear side to retain the edge for a long time.
