DEWALT 20V MAX Metal Shear, Cordless
This cordless metal shear is designed for roofing work where mobility matters. It features a 360-degree swivel head that allows access to tight quarters, such as soffits, under-eave areas, and confined flashing spaces. The tool is optimized for cutting through up to 14-gauge metal, making it suitable for various roofing materials, flashing, and sheet-metal components. A built-in LED work light helps illuminate cut lines in dim or shadowed work areas, improving accuracy and reducing mis-cuts on job sites.
- 360-degree swivel head enables full range of motion in tight spaces
- Cuts 7/32″ strip that curls away from the cutting area for cleaner edges
- LED work light for enhanced visibility along the cut line
- Part of the 20V MAX system for battery compatibility across tools
In roofing tasks, this tool shines when trimming flashing, gutters, and near seams where a traditional shears blade would struggle. The lightweight design reduces fatigue on extended shifts, and the 14GA cutting capability expands the range of materials you can field-cut without swapping tools.
DEWALT 20V MAX Metal Shear, Offset
This cordless offset shear is designed to reach into tight corners and around obstacles common on roof lines and duct connections. The offset design, combined with a 360-degree swivel head, supports circular and curved cuts, making it easier to form seams along curved fascia or curved roof edges. It’s capable of cutting through 18-gauge sheet metal and can handle circular patterns encountered when trimming round duct or contouring metal returns. The tool-free swivel head simplifies adjustments during on-site work.
- 360-degree swivel head for versatile access
- Offset design enables circles and curved cuts
- Ideal for 18GA metal and curved seam work
- Cordless convenience with compatible 20V MAX batteries
For roofing crews that frequently encounter curved detailing, edge trims, or perpendicular joints, this tool provides the maneuverability needed to complete tasks without repositioning the workpiece repeatedly. The offset feature reduces the need for mitering and allows cleaner circular cuts around vents or pipe penetrations.
WEN 3650 Swivel Head Metal Shear
The WEN 3650 offers a swivel head and adjustable speed suitable for a range of roofing tasks. The 18-gauge capacity makes it a solid choice for standard metal roofing materials, while the 4-amp motor provides consistent performance for extended sessions. The tool features a variable speed trigger, allowing operators to dial in the cutting speed to minimize jagged edges when trimming panels or furring strips. Its relatively lightweight design helps reduce operator fatigue during long installs.
- Swivel head for flexible cutting angles
- Variable speed control (0–2500 SPM) for precision
- Cuts up to 18GA sheet metal and up to 20GA stainless steel
- Lightweight and comfortable for extended use
For applications requiring controlled, variable cuts—such as trimming high ridges or making precise contour cuts along curved roofing profiles—the WEN 3650 provides a balance of power and maneuverability. It is especially suitable for crews seeking an affordable option with adjustable speeds and a swivel head for complex layouts.
HURRICANE 10 Inch Tin Snips
HURRICANE tin snips are a traditional choice for sheet metal tasks, offering a straightforward straight-cut option for roofing and flashing work. The snips are designed for 18-gauge material, with chrome vanadium steel blades and a serrated edge to secure the workpiece during cutting. The straight cut is reliable for trimming metal panels to length, feathering edges, or snapping panels to line up with edges and ridges. While not a power tool, these snips provide reliable, controllable cuts when high-speed tools aren’t necessary or practical.
- Straight regular cut for predictable results
- Cut capacity around 18GA sheet metal
- Blades made from chrome vanadium steel with a serrated edge
- Durable hand tool suitable for quick trims on-site
Metal roofing scenarios often require quick field trims near edging or along short lengths where precision trimmers are preferred. These snips complement power tools by allowing rapid, controlled adjustments when a larger tool would be cumbersome or unnecessary.
Malco TSCM Corrugated Metal Turbo Shear Attachment
The Malco TSCM Turbo Shear Attachment is a dedicated accessory for corrugated metal roofing. It enables easy cross-cuts in corrugated panels and fills a niche where standard straight-cut tools struggle to maintain clean lines across waves. The attachment fits both cordless and corded drills, expanding its applicability on job sites where power tools are shared across crews. Its lightweight build and compact drill clamp allow for stable operation, even when cutting across corrugated profiles.
- Makes easy cross-cuts in corrugated metal roofing
- Fits cordless or corded drills for versatile use
- Lightweight with a compact telescoping drill clamp
- Designed to maintain straight lines through variably pressed corrugations
For roofing projects that involve corrugated panels, this attachment can dramatically reduce the time spent trimming and aligning panel widths. It pairs well with a drill that has sufficient torque to handle thicker corrugations without stalling, improving workflow on complex roof assemblies.
Buying Guide
Choosing the right metal shears for metal roofing depends on material, job scope, and workspace constraints. The following considerations help compare cordless shears, drill attachments, and traditional snips to determine the best fit for a given project.
- Material and gauge compatibility: Roofing often uses galvanized steel in the 18–24 gauge range, with aluminum and copper panels common in some installations. Cordless shears like the DEWALT DCS494B are marketed for up to 14GA, while models such as the DCS496B handle 18GA. For corrugated panels, specialized attachments (Malco TSCM) can simplify cross-cuts.
- Cutting geometry and versatility: A swivel head increases accessibility in tight spaces and around vents or ridges. Offsets and curved-cut capabilities help with circular penetrations or shaping around edges, improving edge quality and reducing rework.
- Tool type and power availability: Cordless options offer mobility on ladders and rooftops but may trade off run-time. Drill-attached or dedicated power tools may deliver more torque for thicker materials but require a drill with compatible chuck sizes and stability on uneven surfaces.
- Edge quality and curl management: Some cutters create curled edges or burrs; select tools with cutting-action designs that minimize curling along the cut line for neater finishes and safer edges.
- Safety and ergonomics: Weight, balance, and grip impact fatigue. Tools with LED lighting (as seen on DEWALT models) can improve visibility in shadowed areas. Always wear safety goggles, gloves, and a long-sleeve shirt when working with sheet metal.
- Maintenance and blade life: Many attachments use hardened steel (chrome vanadium in several models). Keep blades clean, lightly lubricated, and free of debris to extend life and prevent jamming or miscuts.
- Budget and value: Cordless shears are generally priced higher than hand snips or simple attachments, but they save time on large roof projects. For corrugated roofing, a combination approach—power shears for long runs and snips or attachments for corners—often yields the best value.
In summary, for metal roofing tasks, prioritize 360-degree swivel heads, compatibility with your power source (cordless or drill-attached), and the appropriate cutting capacity for your material. For corrugated panels, consider a dedicated attachment like the Malco TSCM to simplify cross-cuts. For tight spaces and complex edges, a tool with offset or curved-cut capability can dramatically improve accuracy and efficiency. Always tailor your selection to the typical materials you encounter on the job and the power tools you already own.
