Every seasoned roofer has a few tools they can’t work without—the ones that feel like an extension of their own hands. These are the workhorses you reach for daily, the tools that solve problems and handle multiple tasks with ease. For anyone working with sheet metal, a versatile hand seamer falls squarely into that category. It’s for more than just one job; it’s for shaping panels, making repairs, and perfecting flashing details. The Stortz 90 degree hand seamer is a prime example of such an indispensable tool. We’re going to explore why this seamer is a must-have in any professional’s tool bag, covering its key features, practical applications, and how it consistently delivers on the job.

- Work Smarter, Not Harder: The tool’s design gives you the leverage to make clean, tight bends with less physical effort. This, combined with a comfortable grip, reduces hand fatigue and helps you work more efficiently throughout the day.
- Invest in a Tool That Lasts: The Stortz hand seamer is built from durable, high-quality steel for long-term reliability. A quick wipe-down and proper storage are all it takes to protect your tool and ensure it performs consistently on every job.
What is the Stortz 90-Degree Hand Seamer?
If you work with sheet metal, you know how important clean, precise bends are. The Stortz 90-Degree Hand Seamer is a fundamental tool designed to do just that. Think of it as your go-to for making crisp, 90-degree folds on metal panels, flashing, and trim. It’s a manual tool, which means you get a direct feel for the metal and complete control over the bend, ensuring every seam is tight and professional.
Whether you’re hemming an edge to create a smooth, safe finish or starting the first step in a double-lock standing seam, this tool is indispensable. Its simple, effective design allows you to work directly on the roof, making adjustments and forming pieces without having to run back to a bench brake. It’s one of those tools that, once you have it, you’ll wonder how you ever managed without it. From small repairs to full-scale installations, the 90-degree hand seamer provides the precision needed for high-quality metalwork.
Built to Last: Design and Construction
When you’re on a job site, you need tools that can keep up. The Stortz 90° Hand Seamer is built with durability and efficiency in mind. The design gives you extra leverage, which makes forming tight, clean bends much easier on your hands and wrists. This is especially helpful when you’re working with tougher gauges of metal. The handles are precoated to give you a firm, reliable grip, so you can maintain control whether you’re wearing gloves or working in damp conditions. It’s a straightforward, tough tool made for the demands of professional metalworking.
Available Models and Sizes
One size doesn’t always fit all, and Stortz gets that. The 90-degree hand seamer comes in three different jaw widths, so you can pick the right tool for the job. The available sizes are 1 1/2 inches, 2 3/8 inches, and 3 1/8 inches. The narrower jaw is perfect for detailed work, tight corners, or smaller pieces of flashing where precision is key. The wider models are your workhorses for seaming long, straight runs on panels, letting you cover more ground with each squeeze. Having the right size makes the work faster and ensures a more uniform, professional finish across the entire project.
A Look at Price and Value
A good tool is an investment in your craft, and the Stortz 90-Degree Hand Seamer is no exception. Depending on the size you choose, the price ranges from about $75.00 to $180.00. While you can find cheaper options out there, you’re paying for quality that lasts. This isn’t a tool you’ll be replacing season after season. The durable construction and reliable performance mean fewer frustrations on the job and better results for your clients. When you consider the time saved and the quality of work it produces, it’s a valuable addition to any professional’s tool bag.
How Professionals Use the 90-Degree Hand Seamer
On any given job site, a versatile tool is a valuable tool. The Stortz 90-Degree Hand Seamer is more than just a one-trick pony; it’s a go-to for a variety of tasks that require precision and strength. From forming perfect seams to making quick work of panel removal, this is how experienced roofers put the 90-degree hand seamer to work. It’s an essential part of any professional’s kit for handling detailed metal work efficiently and accurately.
Perfecting Standing Seams
When it comes to standing seam roofing, clean, tight folds are non-negotiable. The 90-degree hand seamer is specifically designed for making these crisp bends. Its angled jaws give you the control needed to form a perfect 90-degree angle on the first pass, setting you up for a clean double lock. But it’s just as useful in reverse. If you need to perform a repair or replace a panel, this tool is ideal for carefully opening standing seams without damaging the surrounding metal. It’s a fundamental piece of equipment for anyone working with metal seaming tools on a regular basis.
Handling and Shaping Panels
Beyond just seaming, this tool is a workhorse for general fabrication and panel manipulation. The design provides excellent leverage, which means you can make tight bends and shape metal panels with less effort. Whether you’re creating a drip edge, hemming a panel, or making a custom flashing detail on the spot, the 90-degree seamer gives you the control to do it right. This ability to handle detailed shaping makes it one of the most versatile metal bending tools you can have in your bag. It saves you trips back to the brake and lets you handle custom adjustments right on the roof.
Creating Double-Seamed Mechanical Locks
Removing double-seamed mechanical lock panels can be a tough job, but the 90-degree hand seamer makes it much more manageable. The tool’s precise jaws allow you to get a firm grip on the seam, making it easier to carefully pry it open. This is especially useful during repair jobs where you need to remove a single damaged panel without disturbing the rest of the roof. Using the right tool prevents you from accidentally creasing or tearing the metal, saving you time and material. For anyone working with mechanical lock seamers, having a reliable way to disassemble them is just as important as putting them together.
Other Smart Uses on the Job
Experienced roofers know that the best tools can handle more than just their primary function. The 90-degree hand seamer is no exception. Many professionals use it for detailed flashing work around chimneys and skylights, where precision is key. It’s also great for fabricating and installing custom gutter tools and downspout components. Because of its compact size and powerful leverage, it’s often the perfect solution for working in tight spaces where larger equipment won’t fit. It’s no surprise that so many pros consider it a “must-have” for its ability to solve problems and handle detailed metal work across the entire job site.

The precoated handles on the Stortz 90° Hand Seamer are designed to enhance your grip, giving you better control and confidence with every move.

Keep Your Hand Seamer in Top Shape
Your tools are an investment, and like any good investment, they need a little care to perform their best. The Stortz 90° Hand Seamer is built tough, but a few simple habits can extend its life and ensure it delivers the clean, precise bends you rely on. Taking a moment for maintenance not only protects your tool but also ensures safety and quality on every job. Think of it as a quick end-of-day routine that pays off for years to come. Here’s how to keep your hand seamer in prime condition, from proper handling to quick inspections.
Handle It Right
Using your hand seamer correctly is the first step to keeping it in great shape. These pliers are specifically designed to give you extra leverage for making tight bends. They’re your go-to for opening standing seams or carefully removing double-seamed mechanical lock panels without damaging the metal. When you let the tool do the work as intended, you avoid putting unnecessary stress on the joints and jaws. This not only preserves the seamer but also helps you work more efficiently and produce cleaner results. Proper technique is key to getting the most out of its powerful design.
Simple Cleaning and Storage Tips
A little cleanup goes a long way. After a day on the roof, take a minute to wipe down your hand seamer. The coated handles are designed for a firm grip and are easy to clean with a simple cloth. Getting rid of any dirt, grime, or moisture is the best way to prevent rust from setting in. Once it’s clean, find a dry spot for it in your truck or workshop. Storing your seamer properly protects it from the elements and keeps it ready for the next job. This simple habit is one of the easiest ways to ensure your tool remains a reliable part of your kit for years.
What to Look For: Quick Inspections
Get into the habit of giving your hand seamer a quick once-over before you start a job. This isn’t about a deep dive; it’s a fast check for any potential issues. Look at the jaws—are they aligned properly? Check the handles and the joint for any signs of excessive wear, cracks, or damage. The Stortz 90° Hand Seamer is constructed for durability, so you likely won’t find issues often. But catching a small problem early can prevent it from becoming a bigger one down the line. A quick visual inspection helps ensure your tool is safe and ready to perform at its best.
Stay Safe on the Job
Your safety on the job is always the top priority. When you’re working with any hand tools, including your seamer, always wear the right personal protective equipment (PPE), especially gloves to protect your hands. Before making a bend, make sure your hands are dry and your grip is secure. The coated handles are designed to help with this, but it’s always good practice to be mindful. Taking these simple precautions helps prevent slips and accidents, allowing you to focus on the task at hand and maintain a smooth, safe workflow throughout the day.
Get the Most Out of Your Tool
Your 90° hand seamer is a workhorse, but even the best tool is better with the right support system. Getting the most out of your investment means pairing it with other quality tools, storing it properly, and knowing you have solid support when you need it.
Tools That Work Well Together
A hand seamer rarely works alone. On any job, you rely on a team of tools to get the project done right. Before bending a seam, you need precise cuts from quality snips or other metal cutting tools. For larger adjustments or creating initial bends, you’ll want reliable metal bending tools on hand. Thinking of your tools as a complete system helps streamline your workflow and ensures every step is clean and professional.
Our Favorite Tool Pairings
For a perfect double-lock standing seam, the 90° hand seamer is your essential first step. After that initial bend, follow up with a double seamer to complete the 180-degree fold for a weathertight seal. This one-two punch is a classic pairing for any roofer. We also recommend keeping a straight hand seamer for hemming edges and a seam opener for adjustments. Having a full set of mechanical lock seamers ensures you’re prepared for any situation.
Smart Storage for Your Tools
A quality tool deserves quality care. Proper storage is the easiest way to extend your hand seamer’s life. After a long day, it’s tempting to toss it in the truck, but taking a moment to wipe it down and keep it dry prevents rust. Store your seamer in a dedicated tool bag to protect it from getting banged up. A company making tools since 1853 knows about longevity, and a little care ensures your tools perform reliably job after job.
Warranty and Support

Frequently Asked Questions
What’s the real difference between this 90-degree seamer and a standard straight one? The main advantage of the 90-degree angle is access. It’s designed to let you get into tight corners and make clean folds right up against a wall or another surface where a straight seamer simply can’t fit. Think of it as your specialist for detailed work around chimneys and skylights, while a straight seamer is your go-to for hemming long, open edges.
I’m not sure which size to buy. Any advice? If you can only add one to your tool bag, the 2 3/8-inch model is a fantastic all-around choice that handles most common tasks with ease. The narrower 1 1/2-inch jaw is perfect for intricate flashing or tight detail work, while the wider 3 1/8-inch model is a real time-saver on long, straight panel seams. Your best choice really depends on the bulk of the work you do day-to-day.
Can this tool be used for anything besides roofing? Absolutely. While it’s a must-have for metal roofing, its precision makes it incredibly useful for other sheet metal tasks. Professionals use it for fabricating custom gutter components, forming HVAC ductwork, and creating detailed flashing for siding and window installations. It’s a versatile bending tool for any job that requires clean, accurate folds in sheet metal.
What kind of metal thickness can this hand seamer handle? This hand seamer is designed for the common gauges of steel, aluminum, and copper used in roofing and architectural sheet metal. The tool’s leverage makes it effective on standard 24-gauge steel and similar materials. For extremely heavy-gauge industrial metals, you would likely need a larger bench brake, but for everyday roofing and flashing, this tool has the strength you need.
Why would I use this manual tool instead of a power seamer? Control and precision are the biggest reasons. A manual tool gives you a direct feel for the metal, allowing you to make small adjustments on the fly for a perfect seam. It’s also lighter, requires no power source, and is ideal for repairs or working in areas where you can’t bring in larger equipment. Power seamers are great for speed on long runs, but this hand tool gives you unmatched control for detailed work.
