UPVC Soffit and Fascia › Caerphilly
Caerphilly sits right at the foot of the valleys, and the weather comes down off the mountain edge with plenty of wind and rain behind it. The boards along your eaves take the worst of that, which is why so many in the town have rotted, split or started to sag away from the rafter ends.
T & T Roofing South Wales is based in Port Talbot and works across Caerphilly and the surrounding villages. We fit UPVC fascias, soffits and bargeboards that are cleaned rather than repainted, with vented soffits so the roof space can breathe, and we deal with the gutters at the same time.

Fascias and soffits on Caerphilly housing
Much of the older housing around the castle and the town centre is terraced, with short eaves runs and boards that have been painted over many times. Water sits behind the gutter and at the board joints, and that is where the rot starts, usually long before anything shows from the pavement.
The large post-war and modern estates are a different job. Longer runs of eaves, bigger gables and more bargeboards mean more boards to take down, and we often find soffits with no ventilation at all. Replacing them with vented boards helps the loft dry out and keeps condensation down. We always check the rafter ends before the new boards go on.
Being on the mountain edge means wind-driven rain gets under loose bargeboards and into open soffit joints. In Bedwas, Machen or Llanbradach the exposure is much the same, so we fix boards firmly along the rafter ends and leave no gaps for weather or birds to use. That wind is the main reason we fix everything firmly and seal the corners.


UPVC roofline jobs we carry out in Caerphilly
- Full fascia and soffit replacement — We strip off the old boards, check the rafter ends and eaves, then fit new UPVC fascias and soffits along the whole roofline of your house.
- Bargeboard replacement — Gable ends on the estates and terrace ends take a beating from wind, so we replace worn bargeboards with UPVC boards fixed securely along the edge.
- Vented soffits and vent strips — Where the old soffit was solid, we fit vented boards or vent strips so air moves through the roof space and the timbers stay drier.
- Gutters replaced alongside — The gutters have to come off to change the fascia, so we fit new gutters and downpipes at the same time, or refit sound ones.
- Capping over or replacing — Where timber is still sound we can cap over it in UPVC, but if the board is rotten we remove it and replace it properly.
- Repairs and partial replacement — A single rotten length or a failed corner can be dealt with without redoing the whole house, if the rest of the boards are sound.
How we approach a roofline job in Caerphilly
We start by looking at the eaves from the ground and, where we can, from the loft, then agree whether the job is a full replacement, a partial one or a cap-over. Access usually means scaffold or similar, which we sort out before the work begins so the boards come off safely.
On older Caerphilly homes we check what the existing soffit boards are made of before they are disturbed, and we handle them accordingly. With the old boards and gutters off, we look at the rafter ends, fit the new UPVC, add ventilation and refit the gutters. Some roofline work may need planning or Building Regulations checks — we advise before work starts.
UPVC Soffit and Fascia Guides for Caerphilly
UPVC Soffit and Fascia in Caerphilly — Common Questions
Can you replace the fascias without touching the gutters in Caerphilly?
Not usually. The gutters are fixed to the fascia board, so they have to come off while the board is changed. We either refit sound gutters afterwards or replace them with new ones, depending on their condition and what you would prefer.
Do UPVC boards need painting?
No. UPVC boards are cleaned down with a cloth and mild soapy water, not painted, which is why they suit exposed homes at the mountain edge. We describe them as very low maintenance, because the gutters still need clearing of leaves and moss.
What colours are available for soffits and fascias?
White is the most common, but darker finishes such as grey and black are available, along with wood-effect finishes. Tell us what your windows and doors look like and we will talk through what sits best on your house.
Will the new soffits stop condensation in my loft?
Vented soffits or vent strips let air move through the roof space, which helps reduce damp air building up. They are not a cure for every condensation problem, but a roof with no ventilation at all will almost always benefit.
Do you cover Bedwas, Machen and Senghenydd as well?
Yes. We work across Caerphilly and the nearby villages, including Bedwas, Machen, Senghenydd, Abertridwr, Llanbradach and Ystrad Mynach. Get in touch with your address and we will look at what the roofline needs.
