Thinking about installing or repairing a metal roof? You’re not alone. Whether you’re a homeowner in Cheyenne or a commercial builder in Lincoln, metal roofing is one of the most durable, stylish, and weather-ready choices you can make. But when it comes to actually working with those tough panels, knowing how to cut metal roofing properly can feel intimidating — especially if you’re doing it for the first time.
Let’s make it easy.
At Pete’s Builders, we’ve worked on countless residential and commercial roofing projects across Wyoming and Nebraska. Here’s our simplified, safe, and expert-backed guide on how to cut metal roofing without damaging the panels (or your hands).
🧰 What Tools You’ll Need
Before diving in, make sure you have the right tools. Here’s a quick checklist of what pros like us at Pete’s Builders use:
- Aviation Snips – great for trimming and tab cuts
- Profile Nibbler – perfect for cutting across ribs
- Double-Cut Shears – ideal for long, straight cuts
- Hand Seamer – for bending and folding trim ends
- Gloves & Safety Glasses – because safety always comes first

✂️ How to Cut Metal Roofing Sheets the Right Way
Step 1: Make Notches Around Obstacles (like chimneys or walls)
Metal roofs aren’t always wide open spaces. You’ll probably need to make custom notches, especially around chimneys, dormers, or wall transitions.
- Start by marking your cuts carefully.
- Use a profile nibbler to slice across the ribs — it punches through metal cleanly.
- Don’t rush! Move slowly for cleaner results.
Step 2: Make Long Straight Cuts
Need a clean line along a panel’s flat section?
- A double-cut power shear works best. It’s fast, accurate, and doesn’t distort the metal.
- Remember: this tool creates a sharp, narrow coil as it cuts — wear gloves and clean up as you go to avoid scratches.
🔩 How to Cut Metal Roofing by Hand
No fancy tools? No worries.
If you’re doing a small job or quick repair, aviation snips will do just fine.
- For curved or short cuts, they work great.
- For longer lines, it’s doable — just be patient and use a straight edge to guide.
Pro Tip: Don’t try to cut thick corrugated panels by hand unless you absolutely have to — your hands (and your roof) will thank you later.
🔄 Cutting & Bending Trim Ends
Every piece of roof trim (like valleys or ridge caps) needs a finishing touch:
- Make short 1″ cuts along each bend using aviation snips
- Then fold the tabs with a hand seamer to close the edge
This seals the gaps and keeps moisture and pests out — a must for Wyoming and Nebraska’s wild weather swings.
🛠️ Common Questions About Cutting Metal Roofing
How do I cut corrugated metal roofing?
Use a nibbler or angle grinder for clean curves and ribbed cuts. Avoid jigsaws — they tend to warp the edges.
Can I use a circular saw?
You can, but it’s loud, messy, and generates hot metal shavings that could damage your panel coating. We don’t recommend it unless you’re using a blade specifically made for metal.
How many cuts will I need for a full roof?
Not many for length — most panels are pre-cut. You’ll do more trimming for vents, ridges, sidewalls, and flashing pieces.
