Fascias & Soffits Step by step Installation Guide

If you are planning on installing new fascia boards for the first time or replacing existing ones on a property, here is a step-by-step guide on how to do so correctly.

Preparation of tools is important for any significant build 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.

The sheathing and the board are the first things to be installed. You need 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 event that the rafter is not sufficient.

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.

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.

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.

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.

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.
