Visual Guide to Siding Installation
This section provides a visual representation of correctly installed siding, common installation problems, and the visual differences between high-quality and low-quality installations. Understanding these aspects is crucial for ensuring a long-lasting and weatherproof exterior for your New Zealand home. A well-installed siding system protects your home from the elements and significantly enhances its aesthetic appeal.
Correct Siding Installation
Imagine a section of horizontally installed weatherboard siding. The bottom edge of each piece of siding is overlapped by the top edge of the piece below it, creating a continuous, water-shedding surface. This overlap should be consistent throughout the installation, typically around 1-1.5 inches. Each piece of siding is fastened securely to the underlying sheathing with galvanized nails or screws, spaced appropriately to allow for expansion and contraction due to temperature changes.
Critically, a layer of flashing, a waterproof membrane, is installed under the bottom edge of the bottom course of siding, extending up and over the top edge of the bottom course, and tucked underneath the next course of siding. This flashing prevents water from penetrating behind the siding and into the wall cavity. At corners, J-channels or similar trim pieces are used to neatly finish the edges and maintain a weathertight seal.
Water Leakage During Siding Installation
A common problem is water leakage caused by inadequate flashing or insufficient overlap between siding pieces. Visualize this: Rainwater is driven by wind behind the siding, particularly at the bottom edge of each course. If the flashing is improperly installed or missing entirely, water will penetrate the wall sheathing. Similarly, insufficient overlap allows water to seep through the gaps between the siding pieces.
The result is water damage to the underlying wall structure, potentially leading to rot, mold, and structural issues. Solutions include carefully reinstalling the flashing, ensuring complete coverage and proper overlap, and re-installing siding sections with insufficient overlap. In some cases, it might necessitate removing sections of damaged siding and sheathing to repair water damage before reinstalling new siding.
High-Quality vs. Low-Quality Siding Installation
High-quality siding installations exhibit consistent overlaps, straight lines, and neatly finished corners. The siding sits flush against the wall, without gaps or significant bowing. Fasteners are evenly spaced and hidden, and flashing is visible only where necessary, indicating a careful and professional installation. In contrast, low-quality installations often show uneven overlaps, gaps between siding pieces, and poorly aligned corners.
The siding might be bowed or warped, and fasteners may be visibly protruding or inconsistently spaced. Flashing might be missing or improperly installed, leaving vulnerable areas for water penetration. A high-quality installation reflects a meticulous approach to detail and adherence to best practices, leading to a durable and aesthetically pleasing result. A low-quality installation, conversely, may lead to early deterioration and require costly repairs.
