Why fascia boards fail
Traditional fascias are painted timber. Once the paint cracks, water gets into the grain, and with a gutter fixed to the front, the board stays damp for long periods. The result is rot, often worst at the joints and corners. Soffits suffer in a similar way, and thin plywood soffits can delaminate and sag. Signs to look for are peeling paint, soft spots you can push a screwdriver into, gutters pulling away and gaps where birds come and go.
What a fascia replacement involves
- Gutters and downpipes are taken down.
- The bottom row of tiles may be lifted slightly to reach behind the fascia.
- Old fascia, soffit and bargeboards are removed.
- Rafter ends are checked; any rot is cut back and treated or repaired.
- New soffit boards go in, with ventilation where the roof needs it.
- New fascia boards are fixed, with an eaves protection tray under the tiles.
- Gutters and downpipes go back up, or new ones are fitted.
That last step is why fascia and gutter work is usually done together. Our gutter replacement page covers choosing a new system.
UPVC fascias and soffits
UPVC boards don't rot, don't need painting and come in white, black, grey, brown and woodgrain finishes. Solid full-replacement boards are thick enough to carry the gutter themselves, and the matching soffit, trims and corner joints give a clean finish. For homeowners tired of repainting every few years, that's the main appeal.
Bargeboard replacement
On a gable end, the sloping bargeboards take the full force of the weather and are often the first boards to rot. They're replaced the same way, with a soffit beneath where there's an overhang. On gables with dry verge systems, the new board needs to line up with the verge units. Dry verges are explained on our dry ridge and dry verge page.
Keeping the roof ventilated
Older lofts were often ventilated through gaps at the eaves. Sealing those with tight new soffits can trap moist air in the roof space and lead to condensation. Vented soffits or over-fascia vents keep air moving, and we fit them where the roof needs them.
Choose the finish after checking what it fixes to
Board colour and shape are only part of a roofline replacement. The rafter ends behind the fascia need to hold the fixings, and the new soffit must suit the ventilation of the roof above. If paint is flaking, establish whether it is simply an ageing finish or a sign of damp timber before choosing a covering board. Ask how concealed damage will be discussed if it becomes apparent when the old boards are removed.
On a gable, the bargeboard and the verge need to meet neatly without blocking the intended drainage or airflow. Around the eaves, retained gutters may need removing and refitting even if replacement is unnecessary. Explain which sides of the property are affected so the scope distinguishes fascia, soffit and gable work. That makes it easier to compare a full roofline proposal with one addressing only deteriorated boards on a single elevation.
Use ground-level photographs to show gaps or peeling areas. Avoid probing timber from a ladder: a visual observation is enough to begin an enquiry.
Quotes and coverage
The cost depends on the length of roofline, the number of storeys, gables and corners, the condition of the rafter ends and whether gutters are replaced at the same time. Our guttering cost guide sets out how these add up. We replace fascias and soffits on homes and commercial buildings across Somerset and Devon, within about 50 miles of Taunton.
