Aluminum Siding: A Comprehensive Guide
Aluminum siding, once a dominant force in the residential siding market, offers a compelling blend of durability, affordability, and relatively low maintenance. While it has been somewhat eclipsed by vinyl siding in recent decades, aluminum still holds its own as a viable option for homeowners seeking a long-lasting and aesthetically pleasing exterior. This comprehensive guide delves into all aspects of aluminum siding, providing you with the information necessary to make an informed decision about whether it’s the right choice for your home.
What is Aluminum Siding?
Aluminum siding is exactly what it sounds like: exterior cladding manufactured from aluminum. Typically, it comes in long, horizontal panels that are installed overlapping each other, similar to wood clapboard or vinyl siding. It’s typically coated with a durable finish, often baked-on enamel or a similar protective layer, to provide color and resist weathering. The aluminum itself is usually relatively thin gauge, but the interlocking installation provides structural rigidity.
The popularity of aluminum siding surged in the mid-20th century as a cost-effective and fire-resistant alternative to wood. While vinyl siding eventually became the more dominant choice due to its lower cost and greater resistance to dents, aluminum retains several advantages that make it a worthwhile consideration.
The Advantages of Aluminum Siding
Aluminum siding offers a number of benefits that appeal to homeowners:
Durability and Longevity
One of the primary reasons homeowners choose aluminum siding is its remarkable durability. Aluminum is naturally resistant to rust and corrosion, making it an excellent choice for environments with high humidity or frequent rainfall. Properly installed and maintained aluminum siding can last for 40 years or more, providing decades of protection and aesthetic appeal.
Fire Resistance
Unlike wood and some types of vinyl siding, aluminum is inherently fire-resistant. This can provide a significant safety advantage, potentially slowing the spread of a fire and giving occupants more time to evacuate. This fire resistance can also translate to lower homeowner’s insurance premiums in some cases.
Pest Resistance
Aluminum siding is impervious to insects and other pests that can damage wood siding. Termites, carpenter ants, and wood-boring beetles pose no threat to aluminum, eliminating the need for costly pest control measures.
Relatively Lightweight
Compared to some other siding materials, such as fiber cement or brick, aluminum is relatively lightweight. This can simplify installation and reduce the load on the building’s structure.
Recyclability
Aluminum is a highly recyclable material. At the end of its lifespan, aluminum siding can be recycled and reused, reducing waste and conserving resources. This makes it a more environmentally friendly option than some other siding choices.
Variety of Styles and Colors
Aluminum siding is available in a wide range of styles, colors, and textures, allowing homeowners to customize the look of their homes. Options include horizontal clapboard, vertical board and batten, and even simulated wood grain textures. The baked-on finishes are generally quite durable and resistant to fading.
The Disadvantages of Aluminum Siding
While aluminum siding offers numerous advantages, it also has some drawbacks that homeowners should consider:
Susceptibility to Denting
Perhaps the biggest disadvantage of aluminum siding is its susceptibility to denting. Even relatively minor impacts from hail, tree branches, or even a stray baseball can leave noticeable dents in the siding. While these dents may not compromise the structural integrity of the siding, they can detract from its appearance.
Fading and Chalking
Over time, the finish on aluminum siding can fade and chalk due to exposure to sunlight and weather. Chalking is the formation of a white, powdery residue on the surface of the siding. While fading and chalking don’t necessarily indicate a problem with the siding itself, they can affect its appearance and may require repainting.
Can Be Noisy
Aluminum siding can be prone to making noise, particularly in windy conditions. The panels can rattle or vibrate, which can be bothersome to some homeowners. Proper installation with sufficient insulation can help to minimize this noise.
Can Oxidize
While aluminum is rust-resistant, it can oxidize, resulting in a dull, chalky appearance. Regular cleaning can help to remove oxidation and maintain the siding’s luster.
Higher Initial Cost Than Vinyl
Generally, aluminum siding has a higher initial cost compared to vinyl siding. However, the longer lifespan and lower maintenance requirements of aluminum may offset this higher cost over time.
Aluminum Siding Installation
Proper installation is crucial to the performance and longevity of aluminum siding. It is highly recommended to hire a qualified and experienced contractor to install aluminum siding. Here’s a general overview of the installation process:
Preparation
The first step is to prepare the surface to which the siding will be attached. This may involve removing old siding, repairing any damage to the sheathing, and ensuring that the surface is clean and dry. It’s also crucial to ensure the walls are properly insulated before installing siding.
Installation of Underlayment
An underlayment, such as house wrap, is typically installed over the sheathing to provide a moisture barrier and improve energy efficiency. This helps to protect the wall structure from water damage and reduce air infiltration.
Installation of Starter Strip
A starter strip is installed along the bottom of the wall to provide a secure base for the first row of siding. This strip is typically made of aluminum or vinyl.
Cutting and Fitting the Siding
The aluminum siding panels are cut to the appropriate length and fitted around windows, doors, and other openings. Careful measurements and precise cuts are essential to ensure a professional-looking installation.
Attaching the Siding
The siding panels are attached to the wall using nails or screws. It’s important to use corrosion-resistant fasteners to prevent rust and ensure a secure attachment. The panels are installed with a slight overlap to allow for expansion and contraction due to temperature changes.
Installing Trim
Trim pieces are installed around windows, doors, corners, and other areas to provide a finished look and seal out moisture. These trim pieces are typically made of aluminum or vinyl.
Sealing
Caulk is applied to seal any gaps or seams to prevent water infiltration. High-quality caulk that is specifically designed for exterior use is essential.
Aluminum Siding Maintenance
Aluminum siding is relatively low-maintenance, but some basic care is required to keep it looking its best:
Regular Cleaning
Aluminum siding should be cleaned periodically to remove dirt, grime, and mildew. A mild soap and water solution is usually sufficient. You can use a soft brush or sponge to scrub the siding. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish. A pressure washer can be used, but exercise caution to avoid damaging the siding. Use a wide fan nozzle and keep the pressure low.
Inspecting for Damage
Regularly inspect the siding for dents, scratches, or other damage. Minor scratches can often be touched up with paint. More significant damage may require replacing the affected panel.
Removing Mildew
Mildew can be a problem in damp or shady areas. To remove mildew, use a solution of water and bleach. Test the solution on an inconspicuous area first to ensure that it doesn’t damage the finish.
Clearing Gutters
Keep gutters and downspouts clean to prevent water from overflowing and damaging the siding. Clogged gutters can also provide a breeding ground for mildew.
Trimming Vegetation
Trim back any trees or shrubs that are touching the siding. Branches rubbing against the siding can cause scratches and dents.
Repainting
Over time, the finish on aluminum siding may fade or chalk. If this happens, you can repaint the siding to restore its appearance. Use a high-quality exterior paint that is specifically designed for aluminum siding. Before painting, thoroughly clean the siding and remove any loose paint or rust. Applying a primer is generally recommended to improve adhesion.
Aluminum Siding Cost
The cost of aluminum siding varies depending on several factors, including the quality of the siding, the size of the house, and the complexity of the installation. Generally, aluminum siding is more expensive than vinyl siding but less expensive than brick or fiber cement siding.
Here’s a breakdown of the costs associated with aluminum siding:
Materials
The cost of the aluminum siding itself will depend on the gauge of the aluminum, the finish, and the style. Expect to pay more for thicker gauge siding and more elaborate finishes.
Installation
Labor costs will vary depending on the contractor and the region. Be sure to get multiple quotes from different contractors before making a decision.
Removal of Old Siding
If you need to remove old siding, this will add to the overall cost. The cost of removal will depend on the type of siding and the complexity of the job.
Additional Costs
Other potential costs include permits, scaffolding, and disposal fees. Be sure to factor these costs into your budget.
As a rough estimate, you can expect to pay anywhere from $3 to $7 per square foot for aluminum siding, including materials and installation. This is just an estimate, and the actual cost may vary depending on the specific circumstances.
