- Ladder or Scaffolding: For safe access to higher areas.
Safety First: Protecting Yourself During Installation
Working with metal involves sharp edges and power tools. Always prioritize safety.
- Wear sturdy work gloves to protect your hands from sharp edges.
- Always wear safety glasses to shield your eyes from metal shavings.
- Use hearing protection when operating power tools like circular saws.
- Ensure your ladder or scaffolding is stable and properly set up.
- Be mindful of electrical hazards, especially if working near power lines.
- Lift panels carefully to avoid strains or dropping them.
Measuring and Ordering Your Corrugated Panels
Accurate measurements prevent costly material shortages or waste. Take your time here.
Measure the height and width of each wall section you plan to cover. Account for windows, doors, and other openings. Add 10-15% extra for waste, especially if you have complex cuts.
Corrugated metal comes in various lengths and widths. Choose a panel length that minimizes horizontal seams where possible. Consult with your supplier about available profiles and finishes.
Preparing Your Wall for Corrugated Metal Siding
A solid foundation is crucial for a long-lasting siding job. Don’t skip these prep steps.
Substrate and Furring Strips for Proper Ventilation
Corrugated metal siding requires a flat, stable surface. It also needs an air gap for ventilation.
First, ensure your existing wall sheathing is sound and free of rot. Repair any damaged areas. Install a vapor barrier or house wrap over the sheathing.
Next, attach vertical furring strips to your wall studs. Use 1×3 or 1×4 pressure-treated lumber. Space them according to your panel width, typically 24 inches on center. This creates the necessary air gap and provides a nailing surface.
Flashing and Moisture Management
Water is the enemy of any exterior. Proper flashing directs water away from your structure.
Install appropriate flashing around all windows, doors, and at the base of your walls. Z-flashing is common above windows and doors. J-channel or specific trim pieces are used around openings.
Ensure all flashing is installed in a shingle-lap fashion. This means upper pieces overlap lower pieces. This directs water downwards and away.
Cutting and Handling Metal Panels
Working with metal requires specific techniques to get clean cuts and avoid damage.
Safe Cutting Techniques for Corrugated Metal
You have a few options for cutting corrugated panels. Choose the right tool for the job.
For short, intricate cuts or notching, metal snips are ideal. They offer good control. For longer, straighter cuts, a circular saw with a metal-cutting blade is fastest.
When using a circular saw, wear eye and ear protection. Clamp the panel securely to prevent movement. Cut slowly and steadily.
Avoiding Damage to Panels During Handling
Corrugated metal can bend and scratch easily if not handled with care.
Always carry panels vertically if possible. This reduces the chance of bending. Avoid dragging panels across surfaces.
Store panels flat on a clean, level surface. Protect them from moisture and debris. Handle them gently to prevent dents or scratches.
How to Install Corrugated Metal Siding: Step-by-Step
Now for the main event! Follow these steps for a professional installation.
Starting the First Panel: Level and Plumb
The first panel sets the tone for the entire wall. Get it right.
Begin in a corner, typically the bottom left or right. Use your level to ensure the first furring strip is perfectly plumb. Mark a plumb line on your house wrap.
Position your first panel against this line. Make sure it’s level along its bottom edge. Use temporary fasteners if needed to hold it in place.
Overlapping and Fastening Corrugated Panels
Proper overlap and fastening are key to a watertight installation.
Fasten the first panel to the furring strips using self-tapping screws with neoprene washers. Place screws in the flat valleys of the corrugations, not on the ribs. This ensures a tight seal.
Space screws every 12-18 inches vertically along each furring strip. Place them every other corrugation horizontally along the bottom edge.
Overlap the next panel over the first by one full corrugation. Ensure the overlap is tight. Fasten the overlapping edge to the furring strip below. Continue this process across the wall.
Working Around Openings (Windows, Doors)
Windows and doors require careful trimming and flashing.
Measure and mark the openings on your panels. Cut the panels to fit precisely around the openings. Use metal snips for intricate cuts.
Install J-channel or trim pieces around the window and door frames before the siding. Slide the cut corrugated panels into these channels. Seal any gaps with exterior-grade sealant.
Trim and Finish Details
Finish your project with appropriate trim for a polished look.
Install corner trim pieces at all exterior and interior corners. These cover exposed panel edges. Use matching screws to fasten them.
Install ridge caps or closure strips along the top edge of the siding. This prevents pests and moisture from entering behind the panels. Ensure all exposed edges are covered and sealed.
Common Pitfalls and Troubleshooting
Even experienced DIYers encounter issues. Here’s how to tackle common problems.
Preventing Leaks and Water Infiltration
Leaks are usually due to improper flashing or fastener installation.
If you notice a leak, first check the flashing around windows and doors. Ensure it’s correctly overlapped and sealed. Reapply sealant where necessary.
Inspect screw locations. If a screw is placed on a rib, it might not seal correctly. Consider adding a dab of sealant over problematic screws.
Dealing with Uneven Panels
Uneven panels often stem from an unlevel starting point or warped furring strips.
If panels appear wavy, check the plumb and level of your initial furring strips. You might need to shim out certain areas behind the furring strips to create a truly flat plane.
When installing, use a long level frequently. This helps catch minor deviations before they become major problems.
Rust Prevention and Panel Maintenance
Corrugated metal is durable, but rust can still be a concern in some environments.
Use only galvanized or coated screws to prevent rust streaks. Ensure all cut edges are sealed or painted with a rust-inhibiting primer if exposed.
Regularly inspect your siding for scratches or damage. Touch up any deep scratches with appropriate metal paint to prevent rust formation.
Maintaining Your New Corrugated Siding
Once installed, corrugated metal siding is relatively low maintenance. A little care goes a long way.
Periodically wash your siding with a mild detergent and water. A soft brush or pressure washer (on a low setting) works well. This removes dirt and grime buildup.
Inspect fasteners and sealant annually. Replace any loose screws or reapply sealant to gaps. Address any minor damage promptly to prevent it from worsening. With proper care, your corrugated metal siding will look great and protect your home for decades.
Frequently Asked Questions About Installing Corrugated Metal Siding
Here are answers to some common questions DIYers have about this project.
Can I install corrugated metal siding directly over old siding?
While technically possible in some cases, it’s generally not recommended. It’s best to remove old siding, inspect the sheathing, install a house wrap, and then add furring strips. This ensures a proper air gap, drainage, and a flat, secure base for your new metal panels.
What’s the best way to cut corrugated metal without specialized tools?
For occasional cuts, heavy-duty metal snips (aviation snips) can work, though they can be slow and tiring for long cuts. A jigsaw with a metal-cutting blade is another option for more intricate shapes. Always wear appropriate PPE, regardless of the tool used.
How do I prevent noise from corrugated metal siding in windy conditions?
Noise typically occurs if panels are not securely fastened. Ensure all screws are tight and properly installed in the valleys with neoprene washers. Using a good quality house wrap and furring strips can also help dampen vibrations. Sometimes, adding a foam backer rod in the panel valleys before fastening can also reduce rattling.
Is corrugated metal siding energy efficient?
Corrugated metal itself has a low R-value. However, when installed with furring strips, it creates a ventilated rainscreen system. This air gap can improve energy efficiency by allowing moisture to escape and reducing heat transfer through convection. Pairing it with good wall insulation is key for overall energy performance.
Do I need to ground corrugated metal siding?
For residential applications, grounding is typically not required by code for non-electrical components like siding. However, if your structure has a lightning protection system or if local codes specify, consult a qualified electrician. It’s usually a non-issue for standard siding installations.
