Need safety tips for cutting corrugated metal roofing with my circular saw

Hey everyone, first time posting here. I'm installing a new metal roof on my shed and bought some corrugated galvanized steel panels. I've got a decent circular saw but I'm nervous about cutting these things. Last time I tried something similar, the metal kicked back and I nearly lost a finger. What's the safest way to cut this stuff? Should I use a different blade? Any tips to avoid turning my shed project into an ER visit?

Welcome to the club! As a landscape architect, I've overseen plenty of metal structure installations. First rule: ALWAYS wear proper PPE - safety glasses, gloves, and hearing protection. For corrugated metal, you'll want a metal-cutting blade with fine teeth (like 60-80 TPI). Make sure it's designed for ferrous metals. Clamp the panel down securely - don't just hold it with your knee like I've seen some guys do. Cut slowly and let the blade do the work. The galvanized coating can create nasty fumes too, so work in a well-ventilated area. Oh, and watch for sharp edges after cutting - they'll slice you up worse than a rose bush.

HVAC tech here - I cut sheet metal daily. VoltVictor's right about the blade, but I'll add: use a straight edge guide unless you're a human laser level. Those panels love to vibrate and wander. Also, consider scoring the cut line first with a utility knife - reduces binding. And for god's sake, unplug the saw when changing blades. Seen too many 'sparkies' forget that basic step. If you're really worried, rent a nibbler - way cleaner cuts and zero kickback risk. Just costs more than your circular saw blade.

DIY dad of three here - been there! I tried cutting similar panels last summer for a chicken coop. My advice: practice on a scrap piece first. I ruined two panels before I got the hang of it. What worked for me was putting foam insulation board underneath to support the panel and reduce vibration. Also, mark your cut line with painter's tape - helps prevent the blade from skating. My wife made me buy Kevlar gloves after my first attempt... smart woman. Oh, and keep kids/pets FAR away - those metal shavings get everywhere and are razor sharp!
