Aluminum siding is a popular choice for homeowners because it is durable, low-maintenance, and energy-efficient. However, installing aluminum siding can be a challenging task, especially for first-timers. In this article, we will provide step-by-step instructions on how to hang aluminum siding, including how to prepare your home, install the siding, and finish the job. By following these instructions carefully, you can ensure that your aluminum siding is installed correctly and will last for many years to come.
Before you begin installing aluminum siding, it is important to prepare your home. This includes removing any existing siding, repairing any damaged sheathing, and installing a moisture barrier. Once your home is properly prepared, you can begin installing the siding. Start by installing the starter strip at the bottom of the wall. The starter strip provides a level surface for the first course of siding. Next, install the corner posts at each corner of the house. The corner posts will help to keep the siding in place and prevent it from buckling. Finally, install the siding panels, starting at the bottom of the wall and working your way up.
Once the siding is installed, you will need to finish the job by installing the trim. The trim will help to seal the siding and give your home a finished look. Start by installing the J-channel around the windows and doors. The J-channel will help to keep the siding in place and prevent water from leaking into your home. Next, install the soffit and fascia boards. The soffit and fascia boards will help to protect your roof from the elements. Finally, install the gutters and downspouts. The gutters and downspouts will help to channel water away from your home and prevent flooding.
Preparing Your Home for Siding Installation
2. Removing Existing Siding
If your home already has siding, you’ll need to remove it before installing the new aluminum siding. This can be a time-consuming and labor-intensive process, but it’s essential to do it properly to ensure that the new siding is installed correctly and looks its best.
To remove existing siding, you’ll need to use a pry bar or a siding removal tool to gently pry off the siding panels. Be careful not to damage the underlying sheathing or framing. Once you’ve removed all of the siding panels, you’ll need to inspect the sheathing for any damage. If there’s any damage, you’ll need to repair it before installing the new siding.
| Type of siding | Removal method |
|---|---|
| Vinyl siding | Use a utility knife to score the siding along the seams. Then, use a pry bar to gently pry off the siding panels. |
| Wood siding | Use a pry bar to gently pry off the siding panels. Be careful not to damage the underlying sheathing or framing. |
| Aluminum siding | Use a siding removal tool to gently pry off the siding panels. Be careful not to damage the underlying sheathing or framing. |
| Stucco siding | You’ll need to hire a professional to remove stucco siding. |
Once you’ve removed the existing siding and inspected the sheathing, you’re ready to start installing the new aluminum siding.
Installing the Starter Strip
The starter strip, also known as the foundation strip, is the first piece of siding you’ll install. It creates a base for the rest of the siding and ensures it’s installed straight and level. Follow these detailed steps for a successful starter strip installation:
1. **Measure and Mark:** Measure the length of the wall where you’ll be installing the siding. Mark the starting point for the starter strip using a level and chalk line.
2. **Install the J-Channel:** Install the J-channel along the bottom edge of the wall, aligning it with the chalk line. Secure it using screws or nails.
3. **Install the Starter Strip:**
a. **Cut the Starter Strip:** Cut the starter strip to the measured length. Ensure it’s straight and has a clean edge.
b. **Apply Caulk:** Apply a bead of caulk to the back of the starter strip, focusing on the areas where it will overlap the J-channel and the siding.
c. **Insert into the J-Channel:** Slide the starter strip into the J-channel, aligning its top edge with the bottom edge of the J-channel.
d. **Nail the Starter Strip:** Secure the starter strip using nails or screws. The fasteners should penetrate through the starter strip, J-channel, and into the wall sheathing. Ensure they’re spaced evenly and not driven in too tightly.
The starter strip should now be securely installed, providing a stable base for the rest of the siding.
Nailing Aluminum Siding Panels
To nail aluminum siding panels, follow these steps:
- Drive the starting nail. Place the first panel at the corner of the house and align it with the chalk line. Drive a nail through the nail hole at the top of the panel, about 1 inch from the edge.
- Nail the top and bottom of the panel. Drive nails through the nail holes at the top and bottom of the panel, spacing them about 12 inches apart.
- Nail the field. Drive nails through the nail holes in the field of the panel, spacing them about 16 inches apart.
- Nailing Tips
Nail Size Nail Type Nail Spacing 1-inch Ring-shank nails 16 inches on center It is important to use the correct type and size of nails when installing aluminum siding. Ring-shank nails are specially designed to hold siding in place and prevent it from pulling out. Nails should be driven straight into the studs, not into the sheathing.
- Overlapping the Panels. When installing aluminum siding panels, it is important to overlap the panels by at least 1 inch. This will help to prevent water from leaking behind the siding.
Overlapping and Interlocking Siding Panels
Aluminum siding panels can be overlapped or interlocked. Overlapping panels are installed with one panel overlapping the edge of the next panel. Interlocking panels have a tongue and groove design that fits together, creating a tighter seal. Both methods have their own advantages and disadvantages.
Overlapping Siding Panels
Advantages:
- Easier to install than interlocking panels
- Less expensive than interlocking panels
- Can be used on uneven surfaces
Disadvantages:
- Not as airtight or watertight as interlocking panels
- Can be more susceptible to wind damage
Interlocking Siding Panels
Advantages:
- More airtight and watertight than overlapping panels
- Less susceptible to wind damage
- Can create a more finished look
Disadvantages:
- More difficult to install than overlapping panels
- More expensive than overlapping panels
- Not as easy to use on uneven surfaces
Factors to Consider When Choosing Between Overlapping and Interlocking Panels
There are several factors to consider when choosing between overlapping and interlocking siding panels, including:

Trimming and Installing Siding Accessories
6. Installing Siding Trims and Accessories
Once the siding panels are in place, you will need to install various trims and accessories to complete the siding system. These trims and accessories serve both functional and aesthetic purposes, providing a finished and professional look to your home.
Here are some common siding trims and accessories:
| Trim/Accessory | Purpose |
|---|---|
| J-channel | Seals the edges of siding panels, preventing water infiltration |
| Soffit | Covers the underside of roof overhangs, providing ventilation |
| Fascia | Covers the exposed rafters at the roofline, protecting them from weather and pests |
| Corner posts | Protects and reinforces exterior corners, preventing damage |
| Drip edge | Directs water away from the siding and prevents it from flowing behind it |
| Starter strip | Provides a straight and secure starting point for the first row of siding panels |
When installing trims and accessories, follow the manufacturer’s instructions carefully. Use proper fasteners and sealants to ensure a weathertight and durable installation.
Finishing Touches and Caulking
Inspecting and Altering the Siding
Once the siding is in place, it’s crucial to thoroughly inspect it for any damages or imperfections. Use a flashlight to reveal any irregularities and address them promptly.
Installing Outside Corners
Outside corners are necessary to hide the edges of the siding and create a seamless look. Measure and cut J-channels or outside corner posts to fit the corners and install them securely.
Installing Mitered Corners
Mitered corners are essential for inside corners or any angles other than 90 degrees. Cut the siding at a 45-degree angle and overlap the pieces to create a smooth transition.
Applying Window and Door Trim
Window and door trim provides an aesthetic finishing touch and helps keep water out. Measure the trim pieces to fit the openings and install them around the windows and doors, using nails or screws.
Installing Fascia and Soffit
Fascia refers to the trim that conceals the ends of the roof rafters, while soffit covers the underside of the roof. Install both fascia and soffit to complete the exterior and enhance the overall appearance.
Caulking
Caulking is indispensable for sealing any gaps around windows, doors, corners, and other potential entry points for water. Use a high-quality exterior-grade caulk and apply it meticulously to prevent leaks and improve the durability of the siding.
Gutter Installation
Gutters are an essential element for diverting rainwater away from the siding and protecting the foundation. Choose a suitable gutter system, measure and cut the gutters to length, and install them using brackets and hangers.
Maintaining Aluminum Siding
Maintaining aluminum siding is relatively easy and can help extend its lifespan.
Keeping it Clean
Regular cleaning is essential to prevent dirt and grime buildup. Use a mild detergent and water and avoid harsh chemicals that can damage the finish.
Checking for Damage

High-pressure washing can damage the siding, so use a gentle spray instead.
Repainting
Aluminum siding typically does not require painting, but it can be done to restore its color or enhance its appearance. Use a high-quality paint specifically designed for aluminum.
Cleaning Gutters
Clean gutters regularly to prevent water from overflowing and damaging the siding.
Checking for Loose Screws
Loose screws can allow siding to sag or detach. Tighten them as needed.
Preventing Rust
Avoid using metal objects on the siding, as they can scratch and lead to rust. If rust occurs, remove it with a mild abrasive cleaner and touch up the finish.
Maintaining a Protective Layer
Aluminum siding often comes with a protective layer that helps it resist corrosion and fading. Inspect this layer regularly for any damage and repair as needed.
