High-Quality Metal Shears
For cutting sheet metal and small sections, you’ll want a pair of sturdy shears. Look for shears specifically designed for cutting metal, with hardened blades that can slice through steel. Aviation snips are a popular choice for roofing pros.
Powerful Nibblers
If you have a lot of metal to cut, nibblers (or nibblers) will speed up the job. These handheld power tools clamp onto the edge of the metal and snip off small sections in smooth curves or straight lines. For roofing, look for nibblers with blades that can cut up to 26-gauge steel.
Reciprocating Saws
For long, straight cuts in sheet metal, a reciprocating saw (or sawzall) works great. Fit the saw with metal-cutting blades and it will slice through panels up to 1/4 inch thick. For the cleanest cuts, clamp the metal sheet to a work surface to keep it stable while cutting.
Angle Grinders
When you need to cut metal in tight spaces or irregular shapes, reach for an angle grinder. These high-speed rotary tools can be fitted with cutting discs that zip through sheet metal. Wear proper safety gear when using an angle grinder, as the discs can kick up sparks.
With the right cutting tools on hand, you’ll be slicing up roof panels in no time. Be sure to also invest in good work gloves, and eye and ear protection, and wear steel-toe boots for the safest DIY metal cutting experience. Happy cutting!
Comparing Nibblers vs Shears for Cutting Metal Roofing
| Feature | Nibblers | Shears |
|---|---|---|
| Cut Types | Curves, intricate shapes, corrugated metal | Straight cuts, wider curves |
| Cut Quality | Clean, minimal distortion | Less waste (especially double-cut shears) |
| Speed | Generally faster | Can be slower for intricate cuts |
| Waste | Produces small metal chips | Less waste (especially double cut shears) |
| Ease of Use | Easy to maneuver, good for tight spaces | Can be tiring for large jobs |
| Cost | Typically more expensive than shears | Wide price range based on type and quality |
Nibblers
If you have a lot of cutting to do, nibblers are probably your best choice. These compact power tools steadily chomp through sheet metal using a punch-and-die mechanism. They require an air compressor or electric power and take some practice to master, but once you get the hang of it, they can zip through metal panels quickly. For curved cuts, look for a nibbler with a pivoting head.
Shears
For small, straight cuts, a good pair of sheet metal shears will do the trick. Manual shears require elbow grease but are very portable. Electric shears can power through sheet metal and are a good choice if you’re cutting a lot of metal or have hand issues. Either type will produce clean cuts and minimal waste. Look for shears rated for cutting your specific metal thickness.
Other Considerations
Think about how much cutting you need to do and how intricate the cuts will be. For long, curved, or awkward cuts, nibblers probably make more sense. For a few quick trims, shears are very efficient. You’ll also want to consider features like adjustable blade tension, ergonomic handles, and safety mechanisms. And don’t forget blade lubricant – it will extend the life of your tools and produce better results.
With the right cutting tools and some practice, you’ll be customizing and installing metal panels in no time. Take it slow, follow all safety precautions, and enjoy your newfound metalworking skills! The results will be well worth the effort.
Best Roofing Saws for Precise, Straight Cuts
| Tool | Pros | Cons |
|---|---|---|
| Circular Saw | Fast cuts, good for straight lines | Requires skill for precision, potential for kickback |
| Reciprocating Saw | Powerful, cuts through various materials | Stationary tools, limited portability, can be expensive |
| Band Saw | Excellent precision, smooth cuts, good for thicker metals | Powerful, cut through various materials |
Circular saws
For making long, straight cuts in metal roofing, a circular saw is ideal. Look for a saw specifically designed for cutting metal, with carbide-tipped blades that can slice through aluminum, steel, and tin. These saws typically range from 61⁄2 to 12 inches in diameter. A smaller saw will give you more control and maneuverability, while a larger saw will cut more quickly through thick materials.
Reciprocating saws
Also known as seawalls, reciprocating saws are very versatile and can cut through metal roofing. They have a blade that moves rapidly back and forth, allowing them to cut in tight spaces. You’ll want carbide-tipped blades designed for cutting metal. While reciprocating saws can cut curves, they may produce rougher cuts than a circular or band saw.
Band saws
For the cleanest, straightest cuts in metal roofing, a band saw is your best option. These saws have a long, flexible blade that rotates on two wheels. Look for a portable band saw designed specifically for cutting metal, with variable speed control and blades with at least 14 teeth per inch. Band saws can cut very precisely, but require more setup to operate safely. They are best if you have a lot of cutting to do and value precision.
Tips for clean cuts
No matter what saw you choose, there are a few tips to keep in mind for making clean cuts:
- Secure the metal roofing to a sturdy work surface before cutting. This prevents vibration and ensures straight cuts.
- Mark your cut line carefully and clamp a straightedge in place as a guide.
- Allow the saw to do the work—don’t apply too much pressure.
- Wear proper safety gear like work gloves, eye protection, and ear plugs. Metal shavings and sparks can cause injury.
- Consider using a lubricant like cutting oil to reduce friction and prevent overheating.
- Go slowly, especially around curves. Rushing can lead to mistakes and ragged cuts.
With the right tools and technique, you’ll be making clean, precision cuts in your metal roofing in no time. The key is using a saw designed specifically for cutting metal, securing the material in place, and letting the saw work at its own pace. Straight, accurate cuts will result in a professional-looking metal roof.

Choose the right tool for the job
The key to clean, accurate cuts is using the proper cutting tool for your specific roofing material and project needs. Shears and nibblers can handle curves and scrollwork, while saws of various types are better for straight cuts. For aluminum, you’ll want carbide-tipped tools, while steel roofing requires high-speed steel. Make sure any power tools you use have adequate torque and RPMs for metal cutting.
Go slowly
Take your time and don’t force the cutting tool. Let it do the work for you. Rushing can lead to slips, inaccurate cuts, and even injury. Go slowly, especially around curves and corners. Lubricate the cutting area with cutting fluid or wax to allow the tool to glide smoothly.
Clamp pieces in place
For straight cuts, clamp the metal sheet to a work surface to keep it stable and secure. This is especially important when using power tools like nibblers, shears, and saws which can cause metal pieces to vibrate. Clamping the sheet in a vise or with C-clamps will result in a cleaner cut.
Wear proper safety gear
Cutting metal roofing can be hazardous, so be sure to wear thick work gloves, eye protection, and steel-toe boots. Flying metal shards and burrs can cause injuries. Consider wearing ear protection as well when using power tools like nibblers which can be quite loud.
Deburr edges
Once cuts are complete, use a file, grinder or deburring tool to smooth any sharp edges or burrs left behind from cutting. Run the tool along the cut edge in one direction until the edge feels smooth. This step is important for safety as well as for the best-looking finished results.
Following these pro tips will have you cutting metal roofing like a pro in no time. Take it slow, use the right tools, clamp pieces in place, wear proper safety gear, and deburr cut edges for clean, professional-looking results. Your roofing project will come together smoothly and efficiently.
