Whether it’s for a barn, garage, or even a modern home exterior, vertical metal siding offers long-lasting protection and a sleek look. They’re low maintenance and available in a variety of colors, accessories, and trim. This vertical metal siding installation guide walks you through the must-know information, the steps, and more so you can make the best decision for your building’s appearance and care.
What Is Vertical Metal Siding?
Vertical metal siding is an exterior cladding that runs from top to bottom on a structure’s walls. Although it’s generally considered a commercial product, it’s also popular for agricultural buildings, workshops, and homes.
Known for its durability, weather resistance, and pest resistance, vertical metal siding can last decades when properly maintained. Plus, this type of siding is easy to clean and doesn’t require much repainting.
Types of Vertical Metal Siding
There are various styles of vertical metal siding available, each offering its own unique characteristics:
- Corrugated panels feature wavy patterns that boost strength, add flexibility, and provide reliable protection against harsh elements.
- Standing seam siding has a sleek design and uses concealed fasteners, giving the structure a smooth and modern appearance.
- Board and batten incorporates alternating wide and narrow panels to add texture, reminiscent of traditional designs.
- Ribbed panels are one of the more popular options. The raised ribs create a unique design and provide strength to the siding.
Vertical Metal Siding Installation Guide
Installation techniques vary depending on the material. Some manufacturers require special procedures and fasteners for the system to work as intended. In this guide, we focus on standard materials and traditional installation methods for vertical metal siding.
Before starting, inspect the existing wall for any damage or unevenness, repair issues, and clean the surface. An even, clean, dry wall results in a better installation process.
We recommend recruiting help. In addition to the siding, you’ll need:
- Chalk line
- Drywall square
- Fasteners
- Hammer
- Level
- Marker
- Measuring tape
- Metal Shears
- Pneumatic nibbler
- Pneumatic shears
- Safety gear
- Trim and J-channel
If your building doesn’t require home wrap, you can use grommeted, metal roofing screws as fasteners. Self-tapping, they don’t need pilot holes. If the structure does have house wrap, use an air-powered tool, such as a pneumatic nailer.
Install vertical siding from the bottom of the structure up, overlapping each course. Work on one wall at a time.
Strike a straight, level line along the bottom of the wall to establish a reference for accurate panel alignment. Use a framing level to mark a plumb line on each corner for the outside corner trim. Install J-channel trim or similar around any obstructions, such as a door or window, to protect the building and siding from water intrusion.
Start with a half sheet so the horizontal joints don’t overlap and to keep water out of the siding. Set the first panel into place, aligned with the plumb and level lines. Secure it to the wall with a galvanized fastener.
The side of the next panel should overlap the previous panel using the rib. Repeat this process around the building.Work left to right or vice versa to attach the next panels. Never go left and right—you could create confusion. Keep each panel plumb and level as you work.
Install the second course over the first course. Each course should overlap the preceding course by at least 2 to 6 inches. This prevents rain and water from infiltrating the panels.
Professionals rarely work alone, as metal siding is awkward to work with and sometimes heavy. A typical installation crew will have one person doing the cutting (often the job foreman) and two laborers performing the installation.
Where possible, use a single fastener for two panels. For example, since the bottom edge of the panel on the second course overlaps the top of the first course, installing an additional fastener into the first course creates a bump and an unnecessary second hole.
Trim the panel to work around obstructions. Insert it into the J-channel or other trim.
Continue this process until all of the siding’s borders are securely inside a channel or overlap the ribs of the adjacent panel.
Once all panels are in place, use a 4-foot level to make another plumb line on the siding. Install the outside corner trim to cover the edges where the walls meet.
Depending on the manufacturer, design, and structure’s purpose, you might want to install a base strip to the bottom panels. The base strip caps off the panels, connects them together, and gives the siding a crisp look. Back out the screws along the bottom edge of the first course and slide the base strip under the panels.
If the structure has a concrete pad, install foam blocks between the bottom of the wall and the back of the siding to fill the gaps between the panel and the wall. This step helps to keep pests out and improve energy efficiency.
Tips for a Successful Installation
For the best results when installing vertical metal siding, keep these tips in mind:
- Work with a partner for added safety and accuracy. Installing large panels alone can be challenging.
- Always wear gloves, goggles, work boots, and other safety equipment.
- Double-check all measurements before cutting to minimize material waste and errors.
- Regularly check for level and plumb for straight panels.
- Metal panels can expand and contract with temperature changes. Fasten them with this in mind to avoid buckling.
- Add house wrap before adding panels for additional energy efficiency and moisture protection. Homeowners often skip this step if the structure is for livestock.
Vertical Metal Siding Designs
Vertical metal siding also offers opportunities for creative expression. To bring personality to the structure, use complementary colors, such as forest green and red or shades of brown. Experts generally recommend a 60/40 split to break up the symmetry.
Choose transition trim to emphasize the building’s features. In addition, you can mix panel styles or orientations for a distinctive look or incorporate other materials to add depth and texture.
How Do I Maintain Vertical Metal Siding?
One of the main advantages of vertical metal siding is its low maintenance requirements. To keep it looking its best and to extend its lifespan, pressure wash the siding annually with mild detergent and water.
Conduct periodic checks for damage or loose fasteners and address any issues promptly to prevent further problems. Keep nearby vegetation trimmed to avoid moisture buildup and potential damage from contact with the siding.
Final Thoughts About Vertical Metal Siding Installation
Metal siding can last decades with minimal attention, which makes it attractive to ranchers, farmers, and commercial builders. However, it’s also ideal for homes and other structures, such as sheds and workspaces. If you decide vertical metal siding is right for your building, always follow the manufacturer’s instructions.
