Metal siding is gaining popularity due to its durability, weather resistance, and aesthetic appeal. Installing metal siding can be a rewarding project for homeowners and professionals alike, provided it is done correctly. This article details the process of metal siding installation, covering surface preparation, tool requirements, installation steps, and finishing touches, based on available documentation.
Preparing the Wall Surface
Proper preparation of the wall surface is critical for a successful and long-lasting metal siding installation. The process begins with removing any existing siding materials and nails. Following removal, the underlying sheathing should be inspected for damage and leveled as needed. A moisture barrier, such as house wrap, should then be installed to prevent moisture buildup behind the siding panels. For uneven surfaces, particularly brick, the installation of furring strips is recommended to create a level mounting surface. This ensures a clean, dry, and level area for the metal siding.
Tools and Materials
A specific set of tools and materials are required for metal siding installation. Essential tools include a power drill or impact driver, metal snips or a circular saw with a metal-cutting blade, a level, a measuring tape, a chalk line, safety glasses, gloves, and hearing protection. A sturdy ladder or scaffolding is also necessary for reaching higher areas of the wall.
The required materials consist of the siding panels themselves (steel, tin, or aluminum are common choices), a starter strip, J-channel and corner trims, furring strips (if needed), house wrap, screws specifically designed for metal siding installation, and flashing.
Installation Steps
The installation process is typically completed in a series of steps, starting from the bottom and working upwards.
Step 1: Install the Starter Strip & Trim
The starter strip is attached along the base of the wall, providing a secure foundation for the siding panels. J-channel is installed around windows, doors, and other openings, while inside and outside corner trims are added to lock the siding panels in place and prevent moisture intrusion. These trim pieces are essential for a weather-tight installation.
Step 2: Hang the Metal Panels
Installation of the metal panels begins in one corner, working outward. Each panel is slid into the starter strip and leveled before being secured with screws every 12–16 inches. It is important not to overtighten the screws, as metal expands and contracts with temperature changes. When installing vertical metal siding, precise alignment is particularly important, as even slight misalignments can be noticeable. Overlap between panels is necessary for proper coverage.
Step 3: Flash and Seal
After the panels are hung, flashing is applied over windows, doors, and roof-to-wall intersections to prevent water penetration. Weather-resistant caulk is used to seal all joints and edges, including corners and trims. This step is crucial for protecting the structure from moisture damage.
Step 4: Finishing Touches
The final step involves a thorough inspection and cleanup. All screws should be checked to ensure they are tight (but not overtightened). Any small scratches on the panels can be touched up with appropriate paint. Finally, the panels should be washed down to remove dust or fingerprints, resulting in a polished and professional appearance.
Considerations and Factors Affecting Cost
Several factors can influence the cost of a metal siding installation project. The type of metal used (steel is generally more expensive than aluminum) impacts the overall price. Panel style, with fancy profiles or corrugated metal commanding a premium, also contributes to the cost. The orientation of the panels—vertical siding often requires more planning and support—and the number of corners (which dictates the amount of trim needed) are additional cost factors.
Labor costs vary depending on whether the installation is a DIY project or performed by professionals. DIY installations are cheaper but require significant time and effort. The condition of the wall also plays a role; damaged sheathing or uneven walls necessitate additional preparation work, increasing the overall expense. Climate considerations may also require special coatings or sealants for regions with harsh weather conditions.
Advantages and Disadvantages of Metal Siding
Metal siding offers several benefits, including exceptional durability (lasting 40 to 70 years), low maintenance requirements (no rotting, peeling, or repainting), fire resistance, and environmental friendliness (recyclability and often made from recycled materials). Its sleek design, particularly with vertical installations, enhances curb appeal, and its reflective properties can help regulate building temperature.
However, metal siding also has some drawbacks. It is generally more expensive upfront than vinyl siding and can dent easily, especially aluminum. It can also be noisy during rain or hailstorms and may be more challenging for beginners to install, particularly steel siding.
Factors to Consider Before Installation
Before embarking on a metal siding installation project, several factors should be considered. The type of metal—steel, tin, or aluminum—should be chosen based on budget, aesthetic preferences, and climate conditions. The panel style and orientation should be carefully planned to achieve the desired look and ensure proper installation. The trim requirements, determined by the number of corners and openings, should be accurately calculated. Finally, the decision between DIY installation and professional assistance should be made based on skill level, time availability, and budget constraints.
Conclusion
Installing metal siding is a significant undertaking that requires careful planning, preparation, and execution. By following the steps outlined in this guide and considering the factors that affect cost and performance, homeowners and professionals can achieve a durable, attractive, and long-lasting siding solution. Proper installation ensures protection against the elements, enhances curb appeal, and adds value to the property.
