UPVC Soffit and Fascia › Cardiff › Guide
Roofline words get used loosely, and a quote can be confusing if you do not know which board is which. Cardiff has a mix of Victorian terraces, villas and 1930s semis, and each shows the three boards in a slightly different way. Here is what they are and what each one does.
The fascia, the board that carries the gutter
The fascia is the board fixed along the ends of the rafters, facing outwards, just under the edge of the roof. It is the board you see when you look up at the front of a house, and it carries the gutter. Because it holds the gutter, it takes the weight of water and often the first signs of rot. It is worth knowing the name when you ask for a quote, so that everyone is talking about the same board.
The soffit, the board under the eaves
The soffit closes the underside of the eaves overhang, running from the back of the fascia to the wall of the house. It stops weather, birds and insects getting into the roof space. On many Cardiff terraces the soffit is solid, but a vented soffit lets air move through the loft, which helps keep the timbers drier. Both boards run the full length of the eaves, so they are usually replaced together.
- Runs between the fascia and the house wall
- Keeps birds and insects out of the roof
- Can be solid or vented to let air in
The bargeboard, the board on the gable edge
A bargeboard, sometimes called a verge board, runs along the sloping edge of a gable end. You find it on semis and villas where the roof ends in a triangle at the side. Some Victorian and Edwardian villas have decorative bargeboards, which need thought when being replaced because plain UPVC will look simpler.
How they fit together on a Cardiff house
On a terrace the roofline is mostly fascia and soffit, running along the front and back eaves. On a semi or villa, the gable edge adds bargeboards, and the corners where these boards meet need careful work. When one board fails, the others around it often follow, so we look at the whole roofline before recommending anything.
- Fascia: faces out, carries the gutter
- Soffit: closes the underside of the eaves
- Bargeboard: follows the gable edge
What replacing them involves
Replacement means taking off the gutters and old boards, checking the rafter ends and eaves, then fitting new UPVC fascias, soffits and bargeboards. On older homes we check what existing soffit boards are made of before they are disturbed. Vented soffits are fitted where ventilation is missing, and the gutters go back or are renewed. Some work may need planning or Building Regulations checks — we advise before work starts.

Common Questions
Is a bargeboard the same as a fascia?
No. A fascia runs along the eaves and carries the gutter, while a bargeboard follows the sloping edge of a gable end. They are often the same material and colour, but they are fixed in different places and do different jobs.
Do all Cardiff houses have all three boards?
No. A mid-terrace usually has fascias and soffits only. A semi, an end-of-terrace or a villa with a gable will also have bargeboards. We look at the roofline of your house and tell you exactly what it has.
Which board rots first?
Usually the fascia, because it sits behind the gutter and takes the water. Soffits come next, especially where gutters leak. Bargeboards rot where wind and rain hit the gable. We check all three before agreeing what needs replacing.
