Fascia & Soffits
Fascia board carries the guttering along the eaves and closes the gap above the wall, taking the weather off the rafter ends. uPVC fascias and soffits come in 9mm and 16mm at 3m and 5m, in widths from 100mm to 405mm. For full replacement thickness, see 16mm fascia board.

Choosing Fascia & Soffits
Frequently Asked Questions
9mm board is capping: it is fixed over sound existing timber to smarten the roofline without stripping back. 16mm is the full replacement thickness, strong enough to carry the guttering on its own once the old timber is off. If the timber behind is soft or rotten, capping over it only hides the problem.
A pitched roof needs continuous airflow at the eaves, so unless ventilation comes from somewhere else — over-fascia vents or a ventilated ridge — the soffit should be vented. Hollow soffit has the gap built into each joint. Flat soffit is unvented, so pair it with a vent strip or circular vents.
Fascia brackets are normally fixed at 800mm to 1000mm centres, closer where snow load is likely, with a bracket within 150mm of every union, angle and outlet. Set a fall of roughly 1:600 towards the outlet, about 3mm per metre, so water runs off rather than standing in the bottom of the gutter.
Look at the front edge from the ground. A plain curve is half round, a flat face with a square shoulder is square, and a moulded, shaped front is ogee. Then measure across the top of the gutter: 112mm and 114mm are the common domestic sizes, with 125mm, 130mm and 170mm on deeper and commercial systems.
