To cut metal corrugated roofing, you need a saw, proper safety gear, and a flat work surface. Metal corrugated roofing is popular because it lasts 40 to 80 years, according to industry data. Cutting this type of roof is not hard if you follow the right steps. You must wear gloves and eye protection every time you cut. This work is dangerous, so take your time and be careful.

What Tools Do You Need?

The best tool for cutting corrugated metal is a circular saw with a metal-cutting blade. You can also use a reciprocating saw or a metal shear. Never use a regular wood blade because it will break or hurt you. A hand shear works too but takes more time and strength.

Mark your cut line with a marker or chalk. Use a straight edge so your line is even. Clamp the metal sheet down hard so it does not move. A moving sheet can cause the saw to slip and hurt you.

How Do You Make the Cut?

Start the saw and let it reach full speed before you touch the metal. Push the saw slowly and let the blade do the work. Do not force it. Pushing too hard can break the blade or cause kickback.

Cut on the valleys, not the peaks, of the corrugated sheet. This makes a cleaner cut. Go slow around curves. Metal corrugated roofing can be sharp after cutting, so wear thick gloves.

What Safety Steps Matter Most?

Wear safety glasses to keep metal bits out of your eyes. Use a dust mask to block metal dust. Gloves are required. Hearing protection is smart because saws are loud. According to OSHA data, roofing remains one of the most hazardous jobs in the U.S., with injuries projected to cost $2.8 billion by 2025.

Never cut metal roofing alone. Have someone watch for safety. Work in daylight or use a work light. Metal corrugated roofing is sharp. Wash your hands and inspect your skin after cutting for small metal cuts.
