The Easy Guide To Installing Plastic Barge Boards

Installing plastic barge boards, also known as uPVC fascia boards, is a manageable DIY project that can improve the aesthetics and durability of your home's roofline. uPVC fascia boards are lightweight, easy to handle, and highly resistant to moisture, rot, and insects, making them a low-maintenance and cost-effective alternative to traditional wooden fascias. With the right tools and materials, and by following the correct steps and avoiding common mistakes, you can achieve a professional finish when installing uPVC fascia boards yourself.

Gather tools and materials

Before you begin fitting plastic barge boards, it's important to gather all the necessary tools and materials to ensure a smooth installation process. Here's a detailed list of what you'll need:

Firstly, you'll require various tools for measuring and cutting. These include a measuring tape to ensure accurate measurements, and a hand saw or power saw for cutting the barge boards to the required size. Additionally, a cordless drill will come in handy for fixing the boards in place. It's also important to have a spirit level to ensure the boards are installed straight and flush with the roofline.

For your safety, it's crucial to wear protective gear, such as safety glasses and gloves, when handling power tools and during the installation process. You may also need a ladder or scaffolding to safely reach the installation area.

In terms of materials, you'll need uPVC fascia boards, fixing nails or screws, and fascia brackets. If you're installing soffit boards along with the barge boards, don't forget to get those as well. Gutter brackets will be necessary if you're reinstalling gutters. If you're replacing existing wooden fascia boards, you'll need a crowbar or hammer for careful removal, ensuring you don't damage the rafter ends which will support the new uPVC barge boards.

Lastly, silicone sealant will be required to seal and protect the installed barge boards. End caps and joint covers are optional but recommended for a polished and professional finish. End caps protect the exposed ends of the fascia boards, while joint covers ensure a seamless look where two boards meet.

Prepare rafters

Preparing rafters for plastic barge boards is a crucial step in ensuring the stability and longevity of your roof. Here are the detailed instructions for preparing rafters:

Mark and Cut the Rafters:

Begin by marking the plumb cuts on the rafter tails. You can do this either from above, standing on the top plate of the wall, or from a ladder or scaffolding below. Ensure the truss tails are straight before cutting and installing the fascia or gutter boards. If they're not straight, snap a line across the top or bottom edges and mark the cuts accordingly.

Install Lookouts:

Snap a line from the eave to the ridge and cut the lookouts in place. This technique ensures a straight barge rafter. If you're working with rafters instead of trusses, you can let the ridge board run long at this stage.

Match the Barge Peak to Ridge Board:

Align the peak of the barge rafter with the centre point of the ridge board. Nail the rafter to the interior board of the barge, spacing the nails approximately every 12 inches.

Measure and Cut the Bottom Rafters:

From the bottom end of each barge, measure the remaining length needed to reach the rafter tail. Cut the bottom rafter sections with the pitch angle to match the opposing rafters. For houses with flat ceilings, secure the bottoms of the opposing rafters together with ceiling joists (rafter ties).

Install the Barge Rafters:

Place the barge rafters on each side of the ridge at the top of the roof. The barge rafter is the outermost rafter on a sloped roof, providing support and framing the gable end. Ensure the rafters are securely fastened to the ends of the rafter tails to avoid rust and weather damage over time.

By carefully following these steps, you will have prepared the rafters for plastic barge boards, contributing to the structural integrity and aesthetic appeal of your roof.

Fix boards with nails or screws

Fixing barge boards with nails or screws is a straightforward process. You can use either fixing nails or stainless steel screws for this process. If you opt for screws, use a cordless drill to fix the boards in place at 600mm intervals. This will ensure a secure fit for your barge boards.

Before you begin the installation, it is essential to have the right tools and materials. In addition to the drill, you will need a spirit level, a hammer, safety gear, and a ladder or scaffolding. It is also recommended to have fascia brackets, silicone sealant, and soffit boards if you are installing them alongside your barge boards.

One important tip to keep in mind is to pre-drill holes into the barge boards to prevent splitting. This will make the installation process easier. If you are installing soffit boards, do so before fully fixing the barge boards in place. Soffit boards provide additional protection and ventilation and should be attached to the underside of the rafters with brackets or fixings. Ensure they fit snugly before securing them.

Finally, you can add end caps and joint covers to create a polished and professional finish. End caps protect the exposed ends of the barge boards, while joint covers are used where two boards meet to ensure a seamless appearance. Following these steps will help you securely fix your barge boards in place and achieve a neat and durable finish.

Install soffit boards

If your home requires soffit boards, it is recommended to install them before fixing the fascia boards completely in place. Soffit boards are placed underneath the fascia, offering additional protection and ventilation to your roof.

To install soffit boards, you will need the following tools and materials:

• Appropriate brackets or fixings
• Measuring tape
• Hand saw or power saw
• Cordless drill
• Hammer

First, use the measuring tape to measure the length of the rafters and cut the soffit boards to size using a hand or power saw. Next, use a cordless drill to make holes in the soffit boards. Then, attach the soffit boards to the underside of the rafters using brackets or fixings. Ensure the soffit boards fit snugly before securing them in place with a hammer.

Ventilated soffit boards are recommended as they improve airflow, reducing condensation in the roof space. You can also install end caps and joint covers to achieve a polished and professional finish. End caps should be applied to the edges of the fascia boards to seal and protect the exposed ends. Meanwhile, joint covers are used where two fascia boards meet, ensuring a seamless look.

Apply end caps and joint covers

End caps and joint covers are essential components that contribute to the overall aesthetics and functionality of your plastic barge boards. Here's a detailed guide on applying them:

Prepare the Fascia Boards: Before applying the end caps and joint covers, ensure that your fascia boards are securely fixed in place. Use a cordless drill to fasten the boards with stainless steel screws or fixing nails at 600mm intervals for a sturdy installation. Remember to pre-drill holes in the fascia boards to prevent any unwanted splitting during the drilling process.

Install Soffit Boards (Optional): If your project requires soffit boards, now is the time to install them. Soffit boards provide additional protection and enhance airflow and ventilation in your roof space. Position them snugly underneath the fascia boards, using appropriate brackets or fixings to secure them to the underside of the rafters.

Apply End Caps: End caps are designed to seal and protect the exposed ends of your fascia boards. They should be applied to the edges of each fascia board. This step ensures that the ends of the boards are protected from the elements and gives your installation a more finished appearance.

Utilize Joint Covers: Joint covers are essential when two fascia boards meet, ensuring a seamless and continuous look to your installation. They provide a sleek finish, hiding any gaps or joints between the boards and creating a professional appearance.

Ensure a Secure Fit: Once you have applied the end caps and joint covers, carefully inspect your work. Ensure that all components are securely fastened and fitted correctly. Use your cordless drill to make any necessary adjustments or to tighten any loose screws or nails.

By following these steps, you will achieve a polished and professional finish to your plastic barge boards, enhancing the durability and visual appeal of your installation.
