Step-by-Step Guide About How To Cut Metal Roofing 2023



Cutting metal roofing may seem challenging, but with the right techniques and tools, you can achieve precise cuts for a perfect fit. In this guide, we’ll walk you through the process of cutting metal roofing, focusing on the essential role of the blade. Know more about how to cut metal and achieve professional results.

Step 1: Gather the Necessary Tools and Safety Gear

Before you start cutting metal roofing, gather the following tools and safety gear:

  • Safety goggle
  • Work gloves
  • Measuring tape
  • Chalk or marker
  • Straight edge or square
  • Power drill
  • Appropriate saw (circular saw, oscillating tool, or electric nibbler)
  • Blade suitable for metal cutting

Step 2: Measure and Mark the Metal Roofing

Measure the dimensions required for your metal roofing and use a chalk or marker to mark the cutting lines accurately. Ensure that your measurements are precise, as any errors can affect the final fit and appearance of the roofing.

To determine the number of panels required for your roof, it is essential to calculate the roof’s area and consider the size of the available roofing sheets. Start by measuring the length and width of each section of your roof if you haven’t determined the panel size. By estimating the dimensions of each section, you can calculate the total area of the roof. Next, take into account the size of the roofing sheets that are available to you for fitting them together. Divide the estimated roof area by the average size of the sheets to determine the quantity of sheets needed for the project. Remember to consider some extra sheets to accommodate for potential waste or errors during installation.

Step 3: Selecting the Right Saw Blade

Types of Blades for Cutting Metal Roofing

There are several saw blade options available, each designed for specific cutting tasks and materials.

  • Metal-Cutting Circular Saw Blades: Circular saw blades designed explicitly for cutting metal are toothed blades with specially hardened teeth. These blades typically have a smaller diameter compared to wood-cutting blades, allowing them to operate at higher speeds. Metal-cutting circular saw blades come in various tooth configurations, including fine-toothed blades for thin metal sheets and coarse-toothed blades for thicker metals.
  • Carbide-Tipped Blades: A smarter replacement for unwieldy circular saw blades is T-REX Carbide Teeth Oscillating Tool Blades. Carbide is a composite material that consists of tungsten carbide particles embedded in a metal binder. This combination of materials provides the blades with superior strength and wear resistance, making them well-suited for cutting through tough materials like metal roofing. Furthermore, the titanium coating provides additional strength and wear resistance, making the blades highly effective in cutting through tough metal roofing materials.
  • Diamond Blades: Diamond blades are specifically engineered for cutting hard and dense materials, including metals with embedded or bonded diamond particles.

Step 4: Preparing the Metal Roofing for Cutting

Place the metal roofing on a stable work surface, ensuring that it is adequately supported. Double-check your cutting lines and use a straight edge or square to create a guide line for your saw to follow. This will help you achieve straight and accurate cuts.

Step 5: Cutting the Metal Roofing

Before you begin cutting, put on your safety goggles and work gloves for protection. Start by aligning the saw blade with the marked cutting line. Apply gentle pressure and let the saw blade do the work, allowing it to cut through the metal roofing slowly and smoothly. Avoid forcing the blade or using excessive pressure, as it can lead to inefficient cutting or damage the blade.

Step 6: Handling Curved Cuts or Notches

If your metal roofing requires curved cuts or notches, use a power drill with a metal-cutting bit to create a starter hole near the desired area. Then, carefully insert the saw blade into the hole and follow the marked cutting line, making precise and controlled movements. Take your time and maintain a steady hand for accurate results.

Step 7: Finishing Touches

Once you have completed the cuts, inspect the edges for any rough or sharp areas. Use a metal file or sandpaper to smooth out any rough edges, ensuring a clean and safe finish.


By following these step-by-step instructions and using the right saw blade for metal cutting, you can confidently cut metal roofing with precision and efficiency. Remember to prioritize safety at all times and choose a high-quality saw blade suitable for metal cutting. With practice, you’ll master the art of cutting metal roofing and achieve professional-looking results for your roofing projects.
