For assistance, here is a list of all the tools and materials you may require: you might only use some of them, but they can all be applicable depending on the type of metal roofing you’re working with. 

Handheld Power Tool 

An angle grinder having a metal cut-off wheel can accelerate cutting through your metal parts, especially if you have a large quantity.

This device enables you to efficiently cut several pieces of metal roofing without the inconvenience of using a manual tool.

It is also helpful for cutting many other things, such as bolts, rebar, fences, steel, and other metals. Having one at home could be very practical. 

Power saw 

A band saw is a good alternative if you lack an angle grinder or prefer a more precise saw for cutting metal roofing. The blade you use must be designed for cutting metal to prevent overheating and potential damage to your material. 

Rotary Cutter 

You can also utilize a circular saw, which can be very useful when cutting through larger sections of metal roofing or making longer cuts precisely. 

Metal Cutting Scissors 

Metal air shears are electric tools used for cutting tin, and they are imposing. They transform your slow tin snip cutting into efficient cuts that reduce hand cramps when working with various types of metal.

If you do this frequently, it’s certainly worth buying. Otherwise, you can even acquire accessories for power drills that can operate a tin snip or metal shear on your behalf. 

Metal Roofing Supplies 

Make sure you have all your metal roofing materials ready before you begin. An expert contractor or a representative from the metal roof manufacturer could assist you in placing the order.

You should be aware of the measurements of your roof and utilize mathematics to determine the quantity of components you will require. 

Note: Consider ordering extra to account for potential problems or mistakes. 

Electric Drill 

A power drill along with drill bit will be essential for cutting circles or squares in the center of your metal panels. Pipe boots or other roofing vents may need to pass through sections of your roof, so cutting out those holes requires careful thought. 

Begin by outlining the object on your roofing material, leaving sufficient room for cutting it to the correct size without removing too much material.

To begin, it is simplest to make a hole in the center using a power drill and drill bit; after that, you may begin cutting with your tin snips, starting from the middle and following your marked lines. 

Horse Bench or Working Table 

Trimming your metal roofing anywhere else than a stable table or sawhorse is a significant error. If you still need one, it’s essential to acquire a sawhorse or a sturdy workbench to remain stable while cutting through these metal components.

Your work area is the initial step in creating a secure and orderly setting for this job. 


Tarps will be very useful to you. When cutting metal, many little bits can fall to the ground, making cleaning up difficult. Placing tarps down first, especially when working in the yard, might collect any tiny debris that falls, ensuring nobody steps on a jagged fragment. 

Cutting tools 

Tin snips are a handheld instrument ideal for cutting small pieces of metal roofing.

They are most effective when the parts are manageable and for narrow angles that are difficult to cut using a more significant tool. Once more, these tools will help you easily remove sections from the middle of your metal roofing. 

Guidelines for Safely Cutting Metal

A shirt with long sleeves and trousers 

Metal fragments can quickly become airborne during cutting; thus, protecting your skin is an excellent method to avoid cuts or scrapes.

How to Slice Metal Roofing in a Step-by-Step Manner 

Now that you’re ready, we can go on to the enjoyable part: how to cut your metal roofing properly. 

How you trim your metal roofing is mainly determined by the type of roofing you have. There are metal shingles, standing seam, stone-coated steel, aluminum, tin, and corrugated metal, and those are only a few examples. 

Although there are several kinds of metal roofing, we may use comparable methods for all of them. For teaching, we will provide procedures for cutting standing seam metal roofing. 

Step 1: Decide how many panels are needed for your roof. 

Collect them in an area where you can trim them, then pile them up for installation.

This guide can assist you in accurately measuring your roof to figure out the number of panels you will require and their appropriate sizes. Make sure to examine your work thoroughly. 

Step 2: Indicate recommendations on your metal sheets for where to cut. 

Because metal roofing is not a forgiving material, it’s essential to have precise dimensions and markers. Use a ruler to draw lines on your metal sheet to show where you will cut. 

Step 3: Prepare your equipment! 

Once you have all your precise measurements and designated your metal panels (at least the initial ones), it’s time to put on the safety equipment.

When you cut metal, little shards and metal fragments fly around. Thus, it’s essential to cover your skin and eyes. 

Step 4: Begin cutting. 

You can use several tools to cut your metal, each with a particular technique or preferred situation. 

Tin snips are a simple tool for making minor cuts manually without using a saw. Tin snips may cut metal like scissors cut paper, but it’s crucial to work carefully and slowly to avoid mistakes. 

Opt for power shears to speed up the process and reduce manual effort. Power shears are similar to a power tool with shears at the end. You may even acquire attachments to transform your power drill into air shears, but in any case, you won’t experience any hand cramps with this approach! 

A circular saw or nibbler would be perfect if you need to cut several sheets simultaneously or want to make fast, straight cuts. A round saw may easily cut through several metal sheets.

If you require greater precision, a nibbler can create smaller incisions in the metal, allowing you to proceed at a slower pace and make more specific cuts. 

Step 5: Create openings for pipe boots and vents. 

You should have openings for pipe boots and vents that fit tightly into the metal paneling. This can be accomplished by outlining the circle or square that needs to be cut and then creating a small hole in the center.

Using a drill bit, you may make a small hole to begin cutting with your tin snips. Next, you may follow your guidelines and ensure you cut to the correct size. 

Step 6: You are prepared to install! 

After cutting all your pieces, you are prepared to install them. Explore other advice about cutting metal below.
