Soffit is an important element in the architecture of many homes. It is an integral part of the interior, and it plays a role in preventing pests and other outside threats from entering your home. It is also an important component in the insulation and ventilation of your home. There are several factors that you need to consider when deciding on the depth of your soffit. These include the type of building, the type of material used, the type of fixings, and the logistics involved.
Soffit boards are usually between 300mm and 400mm deep. They are commonly used under porches and in the main roofing area of a home. They can be plain or vented. They are typically nailed with 25-40mm pins. They should be fixed at 90deg to the wall. The width of the soffit should be measured to ensure the board is wide enough for the width of the roof. A soffit with a wide width can be vented to help with ventilation. A soffit that butts up to the wall should have a seal or mastic. This is because soffit and fascias that do not have a seal can allow airborne moisture to settle and become damp. This can result in condensation and mould issues.
There are various types of soffit boards available in the UK. These include laminated boards and flat boards. The latter are cheaper, but they have visible joining strips. Traditionally, soffit and fascias were made from timber, but now PVC is more popular. The benefits of using plastic soffit and fascias are that they are more maintenance free, easier to clean, and are less likely to rot.
Before deciding on the depth of your soffit, make sure that it meets the building code. If you don’t follow the code, you could end up with a fine. This is especially true if your soffit butts up to the wall.
Once you have decided on the depth of your soffit, you need to find out the type of fixings you need to use. You can either fix directly to the rafter ends or you can use capping boards. If you opt for the latter, you should make sure you have sufficient gable framing in order to securely fix the bargeboards. If you don’t have gable framing, you should install extra fixings at each rafter.
If you decide to fix your soffit to the wall, you should make sure it extends at least 5mm beyond the studwork. This will prevent any gaps from opening, which can allow small insects to enter. In addition, you should make sure the soffit extends at least 40-50mm past the wall.

When installing a soffit, make sure you have the correct tools and materials. It is not worth compromising the integrity of your soffit because of poor fixings. These can cause your soffit to droop and fall. A sharp saw is essential and you should always take lots of measurements.
