What You'll Learn
Screw placement
When attaching corrugated roofing panels, it's essential to use the correct type and size of screws. Wood screws with washers are commonly used, and the washers should be made of rubber to provide a tight seal. The screw length should be chosen based on the thickness of the roofing panels and the underlying structure.
The placement of the screws depends on the orientation of the corrugated sheets. If the sheets are horizontal or diagonal, the screws should be placed in the "hills," also known as the ridges or crests of the corrugations. This ensures proper drainage, as water can flow down into the "valleys" between the corrugations and off the roof.
On the other hand, if the corrugated sheets are vertical, it's recommended to place the screws in the "valleys." This provides a solid contact point with the underlying structure, such as the roof sheathing or plywood. Screwing into the valleys helps to keep the panels tight and secure, preventing any flexing or bending of the hills.
For standard corrugated roofing, the screws are typically placed on the ridges, and a foam packer is used where the screws are driven in. This combination ensures a secure hold and allows for any slight variations in the underlying structure.
It's important to note that screw placement can also depend on the specific product and its design. Some manufacturers may specify screw placement instructions, which should always be followed. Additionally, the spacing between screws is crucial, and adding a "pearling" or an extra screw between panels may be necessary to meet local regulations or structural requirements.
Finally, after driving the screws, it's a good practice to apply a small amount of polyurethane sealant on top of each screw head. This adds an extra layer of protection against the elements and helps prevent leaks.

Sealant
Firstly, when joining panels, use a generous amount of silicone sealant along their vertical length. This will ensure that there are no gaps and that the panels are securely joined.
Secondly, seal any visible seams with sealant. This includes the ridge cap, which may require an additional closure strip and sealant.
When using screws, it is important to note that the heads should not be over-tightened, as this can cause the gaskets to weaken and lead to potential leaks. Instead, the screw head should just meet the corrugated panel, holding it securely in place.
Additionally, consider using flashing to improve the seal, especially if your plastic roofing adjoins another building. This will provide extra weather protection and help to prevent leaks.
Finally, be mindful of the placement of the sealant. In some cases, sealing between adjacent sheets may not be necessary, as the overlap should be sufficient for weather protection. Applying sealant in the wrong place could actually cause leaks by damming drainage.

Materials
When it comes to materials, there are several options for corrugated roofing. PVC, polycarbonate, or vinyl roofing are popular choices due to their translucency, allowing daylight to enter through them. These materials are ideal for structures like chicken coops, greenhouses, or low-profile carports. On the other hand, if you prioritise durability and cost-effectiveness, aluminium panels might be a better option. They are lightweight, more durable than plastic (with a lifespan of up to 50 years), and often more affordable than other metal panels. Additionally, aluminium won't rust, making it suitable for humid, salty environments. However, its lightweight nature also makes it more prone to dents and divots.
For those seeking even greater durability, corrugated terne (stainless steel pressed between layers of tin) is an excellent choice. This material can withstand extreme weather conditions and can last over a century. However, terne tends to be the most expensive option and is generally more challenging to work with.
When installing corrugated roofing, you will also need screws or nails with rubber washers or seals to secure the panels. It is recommended to follow the manufacturer's instructions for screw placement to ensure proper drainage and avoid leaks. Additionally, you may require materials like flashing, peak seals, closure strips, edging, and finishing components, which are sometimes included with the roofing panels. An underlayment is also necessary to provide a base for the roofing.
To enhance the durability and longevity of your roof, consider using a sealant. A coat of clear polyurethane, for example, can provide increased UV protection and delay degradation. Additionally, some roofing manufacturers offer contoured mounting blocks that can be installed under the roofing to ensure the material is always in contact with something and to keep bugs out. These blocks can be made of foam or sturdy wood, depending on your needs.

Cutting panels
Cutting the panels for corrugated roofing is a straightforward process, but it requires careful measurement and the right tools. Here is a step-by-step guide to cutting panels for corrugated plastic roofing:
Firstly, measure the area of your roof. Use a ladder to safely access the roof and take measurements of its dimensions. Make sure to measure the length and width of the roof, as well as the angle or pitch of the roof if applicable. Take note of any specific requirements or challenges presented by your roof's design.
Next, you will need to transfer these measurements to your corrugated panels. Mark the panels with the required dimensions, using a straight edge if necessary, to ensure a straight cut. It is important to measure twice and cut once to avoid mistakes.
When it comes to cutting the panels, an angle grinder is the tool of choice. Angle grinders can be equipped with different cutting discs, so select an appropriate disc for cutting corrugated plastic. Carefully cut along the marked lines on the panels, taking your time to ensure a straight and precise cut. Wear appropriate safety gear, including eye and ear protection, and consider using a respirator to avoid inhaling plastic dust.
Depending on the complexity of your roof design, you may need to make additional cuts or adjustments. For example, you may need to cut holes for vents or skylights, or trim the panels to fit around obstacles like chimneys or pipes. These additional cuts should be measured and marked accordingly, and you may need to use a jigsaw or hand saw for more intricate cuts.
Finally, it is important to handle and store the cut panels with care. Corrugated plastic panels can be lightweight and relatively fragile before installation, so avoid stacking them too high or placing heavy objects on top. Store them in a safe area where they won't be damaged by strong winds or falling debris before you're ready to begin the installation process.

Installation
To install corrugated plastic roofing, you will need to take some measurements, cut the panels to size, and then fasten them in place. Here is a step-by-step guide:
Measure and Cut the Panels
First, measure the area of your roof using a ladder and a tape measure. Then, use an angle grinder to trim the corrugated panels to size.
Prepare the Roof
Roll out an underlayment and install flashing on the eaves of the roof. Flashing is a thin, continuous piece of material that is installed to prevent water intrusion at joints.
Install the Panels
Attach the roofing panels starting from the eaves, overlapping them by about 3 to 4 inches (7.6 to 10.2 cm). This overlap is achieved by placing the panels onto closure strips, overhanging the edge by about 4 inches (10 cm).
When screwing the panels in place, use 1.5-inch (3.8 cm) wood screws with washers. Drive the screws so that the head of the screw just meets the corrugated panel to hold it securely, but do not overtighten as this may dent or dimple the panels.
Complete the Installation
Continue installing panels, overlapping each row by 4 inches (10 cm), until the entire roof is covered, leaving the peak exposed. Then, install peak caps on top of the panels and seal any visible seams with a sealant.
It is important to follow the manufacturer's instructions for screw placement and to check local regulations, as these can vary. Additionally, some regions may require paper and wire mesh to be fitted under the roofing material for condensation control.
