What You'll Learn
Planning and preparation
Firstly, check your local building code for any restrictions or requirements specific to plastic roofing panels. This is an important step to ensure your project complies with local regulations.
Next, gather all the necessary tools and materials. You will need items such as polycarbonate panels, closure strips, screws, washers, a suitable drill bit, a measuring tape, a saw, and safety gear like gloves and goggles.
Before beginning installation, ensure your supporting structure is level and sturdy. Any inconsistencies can lead to improper sealing and water leakage. The structure can be made of wood, metal, or aluminium, depending on your specific project. It is also important to choose the right type of polycarbonate sheet for your project, considering factors such as UV protection, light transmission, and impact resistance.
When designing your roof, account for the width of the sheets and the corrugation overlap. The minimum slope for a plastic roof should be one inch per foot, or a minimum of 10 degrees, to allow for proper water drainage. If your roof has a shallower pitch, additional weatherproofing measures may be necessary.
If installing in summer, remember that the plastic roofing will expand in the heat and shrink in colder temperatures. Therefore, factor in temperature changes and adjust the expansion gap accordingly.
Finally, prepare the panels by removing any protective films and stickers from their surface. This will ensure your panels are clean and clear. To determine the cut length of the panels, measure from the top of the top purlin to the bottom of the bottom purlin. Generally, the only necessary cuts are straight cuts to trim the length.

Transporting and storing panels
Transporting and storing plastic roofing panels is an important step in the installation process, as improper handling can lead to damage and increased installation difficulty. Here are some detailed guidelines for safe transportation and storage:
Transportation:
When transporting roofing panels, it is crucial to handle them with care to prevent kinks, dents, bends, or scratches. Ensure that the panels are securely fastened during transportation to avoid panels rubbing against each other or other objects, which could damage the paint system. Secure the panels above ground level to prevent contact with the ground, as this could scratch or damage the panels.
Storage:
Proper storage of plastic roofing panels is essential to maintaining their quality and integrity. Firstly, store the panels under a covering or roof to protect them from the elements. If storing outdoors, cover them with a loose-fitting, waterproof tarp to shield them from rain, snow, direct sunlight, and debris. Ensure the tarp allows for adequate air circulation to prevent moisture buildup.
When placing the panels, lay them on a flat surface, such as a pallet or two-by-fours, ensuring the surface supports the entire length of the panels to prevent warping. Avoid stacking panels directly on the ground, as this can lead to scratches or negative reactions with the paint. Additionally, be mindful of the panels' sharp edges when storing, keeping them away from active work areas to prevent safety hazards and ensure they don't obstruct daily tasks.
By following these transportation and storage guidelines, you can help ensure the panels remain in optimal condition and facilitate a smoother installation process.

Fastening and sealing
Fastening plastic roofing panels requires careful planning and consideration of the materials used. Before beginning the installation, it is crucial to understand the key factors, such as proper alignment, securing methods, and drainage optimization, to achieve a durable and effective installation.
When it comes to fastening the panels, it is recommended to use typical fasteners like weatherproof nails or wood screws with neoprene washers. Self-tapping screws and grommet-type fasteners are also suitable options. The choice of fastener depends on the type of corrugation and understructure material. It is essential to follow the manufacturer's recommended procedures when using tools, fasteners, sealants, and adhesives. Additionally, appropriate safety equipment, such as safety glasses and filter masks, should be worn during the installation process.
To ensure a secure fastening, the panels should be pre-drilled before installing. The pre-drilled holes should be a minimum of 1/16" larger than the fastener diameter. For panels longer than 3.6m (12'), it is recommended to pre-drill with a 10mm (3/8") hole to accommodate for increased expansion and contraction due to their longer length. BDN Fasteners offer products like POLY-FAST™ and POLYXPAND™, which eliminate the need for pre-drilling and provide a thermal expansion hole, fixing plastic sheets in one go.
Sealing the plastic roofing panels is another critical aspect of the installation process. To achieve an effective seal, vinyl lap seal and/or mastic should be used on side-laps and end-laps. Overlapping the panels is also essential for proper sealing. The recommended overlap is 2.67" x 9/16", as this provides the best protection against leakage and air infiltration. For multi-panel runs, it is advisable to start installing the sheets on the side away from the wind and rain direction. Additionally, the corrugated channels of the panels should be installed sloping downwards to reduce the accumulation of dirt and moisture.
