How To Install Fascias

If you choose to install a fascia onto your property rather than hire a professional company, you need to have a clear idea of what to do. Securing a new fascia board into place is not a difficult job and can be done well as long you do it safely and carefully.

To help you along we have put together a guide on how to install a fascia onto your home. This will help with the ongoing protection of your property while also improving its overall kerb appeal.

Step-By-Step Guide

If you are planning on installing new fascia boards for the first time or replacing existing ones on a property you have just moved into, here is a step-by-step guide on how to do so correctly. It’s important to find the right fascia for your home and the Homeline Flat Board White comes highly recommended. There is a choice of widths between 150-250mm and at 5m long.

  1. Preparation of tools is important for any significant DIY job. Have everything you need to hand before you begin working on the fascia board. This will save you time and stop you from having to go back and forth collecting the tools as and when you need them.
  2. The sheathing and the board are the first things to be installed. You have the preference to decide which one comes first although try to get into the habit of fixing the sheathing and fascia board first to make the job more efficient. The reason is this will ensure they fit perfectly into the roof. Sub-fascias are also a good idea, which act as boards behind the fascias. These help to straighten the main fascia in the even the rafter is not sufficient.
  3. White fascias should be fixed with a minimum of 600mm centres, while foiled fascias require a 40mm centre. Marine grade stainless steel plastic headed nails are the products to use for this.
  4. Leave a gap of 10mm between joints to allow for any expansion within the building. Use superglue to secure the joints on just one side of the fascia. If this is not done they detach over time.
  5. If you are installing ventilation this needs to go directly on top of the fascia board to create an air pathway in order to comply with current building regulations.
  6. Be aware of the type of roof you are working with. This will affect how you will install the fascia board onto the roof. For example, hip roofs allow you to quickly attach the fascia onto the rafter. On the other hand, a gabled roof may require you to create markings on the board to ensure you get the right fit.
  7. The depth of the fascia board plays a key role in ensuring the installation goes correctly. On tiled roofs, there will be extra weight pushed up against the fascia, and without the right amount of depth, it could eventually collapse.

Health and Safety Tips

Anytime you are carrying out a DIY job safety is always of the utmost importance. This is especially true when you are working height up a ladder. Below are some basic health and safety tips to follow so you remain safe at all times.

  • Fall hazards

When you are up a ladder for any length of time always take care to ensure the ladder is in good working condition and firmly secured before going up. It should be able to support your weight along with that of any of the tools you will be using. Check the floor before placing the ladder into position to check it is level and not uneven. If possible, it may be a good idea to have someone else at the bottom of the ladder holding it in place while you work.

  • Tool safety

Whether it’s a power or standard tool you are using, care has to be taken every time you are preparing to use them. When not handled properly it can lead to serious damage to yourself and the property and even make you slip and fall.

  • Outdoor temperatures

Working on the roof to install a fascia could mean being exposed to the sun for long periods of time. During the summer there is a likelihood there may not be any shade and it helps to take regular breaks to drink water. Step out of the intense heat that will also be reflecting back off the tiling to avoid damaging your skin from exposure to excessive UV rays.

  • Keep the workspace tidy

You will require a number of tools to install a fascia onto the roof and you need to know where they are at all times. You do not want to step back off a ladder and onto a tool of some kind. Always keep children and pets away from the workspace. This is a small but important rule that should be followed at all times.
