How to Cut Corrugated Metal Roofing: A Step-by-Step Guide

When it comes to roofing materials, corrugated metal has become a popular choice due to its durability and affordability. However, cutting corrugated metal roofing can be a challenge if you don’t have the right tools and techniques. In this article, we will provide you with a step-by-step guide on how to cut corrugated metal roofing effectively and safely.

Tools and Materials You Will Need

Before you start cutting corrugated metal roofing, it’s important to gather all the necessary tools and materials. Here are the items you will need:

  • Safety goggles
  • Work gloves
  • Tin snips
  • Circular saw with a metal-cutting blade
  • Marker or pencil
  • Straightedge or measuring tape
  • Clamps
  • Workbench or sawhorses

Having these tools and materials ready will ensure that you can complete the cutting process efficiently and safely.

Step 1: Measure and Mark

The first step in cutting corrugated metal roofing is to measure and mark the area you want to cut. Use a measuring tape or straightedge to determine the exact dimensions. Mark the cutting line using a marker or pencil, ensuring that it is clear and visible.

Pro tip: It’s recommended to measure twice and cut once to avoid any mistakes or inaccuracies.

Step 2: Secure the Metal

Next, you’ll need to secure the corrugated metal roofing to a workbench or sawhorses. This will prevent it from moving or vibrating during the cutting process, ensuring clean and precise cuts. Use clamps to secure the metal firmly in place.

Step 3: Cutting with Tin Snips

If you’re cutting a small section of corrugated metal roofing, tin snips can be a handy tool. Start by making a small cut near the edge of the metal, following the marked cutting line. Continue cutting along the line, applying steady pressure to the snips. Repeat this process until you have cut through the metal.

Pro tip: To make the cutting process easier, be sure to use tin snips specifically designed for cutting metal.

Step 4: Cutting with a Circular Saw

For larger sections or straight cuts, a circular saw with a metal-cutting blade can be more efficient. Before using a circular saw, ensure that you have the appropriate safety gear, such as safety goggles and work gloves. Align the saw blade with the marked cutting line and slowly guide the saw along the line, applying gentle pressure.

Pro tip: To prevent the metal from vibrating or moving during the cutting process, you can use clamps to secure a straightedge as a guide for the circular saw.

Safety Precautions

When cutting corrugated metal roofing, it’s essential to prioritize safety. Here are a few safety precautions to keep in mind:

  • Always wear safety goggles and work gloves to protect your eyes and hands from potential hazards.
  • Ensure that the work area is well-lit and free from clutter.
  • Take breaks if you feel fatigued to maintain focus and prevent accidents.
  • Follow the manufacturer’s instructions for the tools and equipment you are using.

By following these safety precautions, you can minimize the risk of accidents and injuries while cutting corrugated metal roofing.


Cutting corrugated metal roofing may seem daunting, but with the right tools and techniques, it can be a manageable task. By measuring, marking, and using the appropriate tools, such as tin snips or a circular saw, you can achieve clean and precise cuts. Remember to prioritize safety by wearing protective gear and following safety precautions. Now that you have a step-by-step guide, you can confidently tackle your corrugated metal roofing cutting project.

Frequently Asked Questions

What tools do I need to cut corrugated metal roofing?

To cut corrugated metal roofing, you will need a few essential tools:

1. Circular saw: This is the most common tool used to cut metal roofing. Make sure to use a carbide-tipped metal-cutting blade for best results.

2. Tin snips: These are handheld cutting tools specifically designed for cutting metal. They are great for making detailed cuts or trimming edges.

3. Angle grinder: This power tool is equipped with a cutting wheel that can easily cut through metal. It’s ideal for making straight cuts or cutting through thicker metal roofing.

How do I measure and mark the corrugated metal roofing for cutting?

Before cutting the corrugated metal roofing, it’s important to measure and mark the desired dimensions accurately. Here’s how:

1. Measure: Use a measuring tape to determine the length and width of the metal roofing panel you need. Make sure to account for any overlaps or trim allowances.

2. Mark: Use a permanent marker or chalk to mark the measurements on the metal roofing. Double-check the markings to ensure accuracy.

3. Connect the marks: Use a straightedge or a ruler to connect the marked points, creating a cutting guideline that will help you make precise cuts.

How do I cut straight lines on corrugated metal roofing?

To cut straight lines on corrugated metal roofing, you can use a circular saw or an angle grinder with a metal-cutting blade. Here’s the step-by-step process:

1. Secure the metal roofing: Place the metal roofing panel on a stable surface and clamp it down to prevent movement during cutting.

2. Align the cutting tool: Position the circular saw or angle grinder along the marked cutting line, ensuring that the blade is aligned properly.

3. Cut along the line: Turn on the tool and slowly guide it along the cutting line, applying steady and even pressure. Let the tool do the work and avoid forcing the blade through the metal.

4. Smooth the edges: After cutting, use a metal file or sandpaper to smooth any rough edges or burrs left by the cutting process.

What is the best way to cut curves on corrugated metal roofing?

Cutting curves on corrugated metal roofing requires a different approach compared to straight cuts. Here’s the recommended method:

1. Mark the curve: Use a flexible measuring tape or a string to mark the desired curve on the metal roofing. Make sure to use a smooth and continuous curve for best results.

2. Use tin snips: Start by making small cuts along the marked curve using tin snips. Gradually work your way along the curve, making small, precise cuts.
