There is no single best material for fascia boards. There is a best material for a particular house, and it depends on three questions: how long you need the boards to last before anyone has to think about them again, how much upkeep you will accept, and what the building itself is. A 1990s semi on an estate and a stone cottage in a conservation area are different jobs, even when the length of board is the same.
We compare uPVC, timber and aluminium on life, upkeep, appearance and fit. The lifespan figures come from published guides, and they disagree, which we say where it matters. If you already have boards you are thinking of covering over rather than replacing, read capping over old fascias first. The wider work is on our guttering, soffits and fascias page, and for prices, see fascia, soffit and gutter replacement costs.
What the three materials are, and where each is used
uPVC is a rigid plastic (the "u" stands for unplasticised). Fascia and soffit boards in uPVC are extruded in long lengths, usually white, though black, brown, grey and wood-effect finishes are made. Timber boards are cut from softwood or hardwood, primed and painted or stained. Aluminium boards are formed from sheet and powder-coated, or sometimes wrapped over a core, in a range of colours.
Each is used for the same two jobs: the fascia, which is the outward-facing board at the eaves, and the soffit, the panel shutting off the underside of the overhang. A house does not have to use one material for both. A timber fascia with a vented uPVC soffit is a common mix, and so is a metal fascia above a timber soffit on an older building.
Beyond the boards, the material choice runs through the whole roofline. The gutter fixed to a fascia is usually a different material again, and our guide to uPVC, cast iron or aluminium gutters covers that side.
How long each one lasts
Published lifespans for roofline materials are far from agreed. For uPVC, MyBuilder's 2026 guide says uPVC fascias and soffits are replaced, typically, within 10 to 20 years, with a check recommended roughly every five. The Plastic Centre, a retailer, says high-quality uPVC can last 20 to 40 years. The gap between the two is partly the difference between an average board and a good one, and partly the difference between a seller's view and a roofer's.
We treat the lower figure as typical and the higher as what a good board in a sheltered position might reach. Our guide to uPVC fascia lifespan goes through what shortens it: sun-bleached and brittle boards, warped lengths and failed joints.
Timber and aluminium
Painted timber lasts as long as the paint film and the timber behind it stay sound. A board kept painted can serve for a very long time; one left bare at the bottom edge, where water collects, rots from there. Aluminium does not rot, so its life is governed by the coating, the fixings and the joints rather than the metal. Neither has a published life that we would quote as typical, so judge them by their condition on the day of the survey, with photographs.
Treat every roofline lifespan as a range that depends on position, paint or coating, and how often someone looks at the boards.
Upkeep: what each asks of you
Upkeep is where the three materials differ most.
uPVC
A uPVC board needs washing now and then. It never needs painting, which is its main appeal. What it does need is an occasional look at the joints and the corner pieces, since a joint that opens lets water in behind the board where nobody can see it. If a board does fail, it is replaced as a length, not repaired.
Timber
Timber needs the most attention. It wants repainting or restaining on a cycle that depends on its position, and the bottom edge and the joints deserve a close look each time. The reward is that timber can be repaired. A section of rot can be cut out and a new piece spliced in, which suits a board that is mostly sound.
Aluminium
Aluminium needs little more than washing. It will not rot or need paint, but it can be dented by a ladder, and a scratch through the coating on a cheap board can show bare metal. Joints between lengths and at corners are the points to watch.
All three can hide damage behind them. Our guide to rotten fascia boards explains why the timber behind the board matters more than the board itself.
How each looks, and how it sits on a stone house
Appearance is a matter of proportion as much as colour. A uPVC board is a standard section, often thinner and flatter than the boards a house was built with, and its face is smooth and slightly glossy. On a 1960s or 1980s house that looks right. On a Cotswold stone cottage with deep, shadowed eaves it can look out of scale, which is one reason conservation officers often prefer timber.
Timber can be made to a profile, with the thickness and bead of the original. Painted in a dark or traditional colour, it reads as part of the house, not an addition to it. Aluminium sits in between: it is thin, crisp and available in dark colours, which suits modern and extended houses, though it is rarely a match for old work.
Black and dark colours
Dark roofline colours have become popular. The effect depends on the surrounding stone and slate, and on whether the house sits in the sun or the shade of a valley side. We look at that in black rooflines.
Soffits are a slightly different choice
The soffit is out of sight from most angles, so the decision turns on function more than looks. A soffit has to resist damp, let the eaves breathe where the roof needs it, and stay fixed to the rafters over the years without sagging. It also tends to be where birds and wasps try to get in, so the boards need to meet the fascia tightly all the way along.
Ventilated or plain
Venting means slots, or a continuous strip, cut into the board so air can pass into the loft. uPVC soffits are made in vented and unvented forms, which makes it simple to add airflow to a roof that lacked it. Timber soffits can be drilled or fitted with a vent strip. Whatever the board, the ventilation must stay open: paint, loft insulation pushed too far to the eaves and nests are the usual causes of blockage. Our guide to soffit ventilation looks at what a loft needs.
Older soffits of unknown board
Boards fitted in the middle of the last century may be asbestos cement. We do not drill, cut or break an old board until we know what it is; see asbestos soffits.
Conservation areas, listed houses and the planning team
The material question has an extra layer on a protected building. Stroud District has 41 conservation areas, and five of those carry Article 4 Directions, among them Bisley and Frampton on Severn. Whether the directions reach roof edges is not stated on the council's page, which recommends asking the planning department.
Listed buildings are different again. The council describes listed status as full legal protection, inside and out, for the entire building, whatever its grade. Replacing a timber fascia with plastic may be an alteration that affects character, and so a matter for the council. We would not start without asking.
Like-for-like replacement is also our rule on older roofs: timber stays timber, and a cast iron gutter stays cast iron where the house calls for it. For the rules and the typical outcomes, see roofline work in conservation areas, and for cast iron on its own, cast iron gutters.
Replacing now or later: a way to think about the cycle
A material choice is also a choice about when you will next be standing under the eaves with a ladder. A board that lasts the 10 to 20 years MyBuilder gives as typical for uPVC means a second replacement within the time many people own a house. A timber board kept painted asks for smaller jobs more often and a replacement less often. Neither is wrong; they suit different owners.
If you plan to sell in a few years, a clean, sound board in a style that suits the house is what a buyer sees. If you plan to stay, the question is how much of your own time the boards will take. Either way, the best moment to change a fascia is while a scaffold stands for another job, such as a re-roof or chimney repair, because access is the largest single cost.
That is also the time to look at the gutters. A new fascia with an old, tired gutter fixed to it is a missed opportunity, and the material of the gutter should be chosen with the board in mind.
Choosing between them: a side-by-side view
| Material | Published life | Upkeep | Best suited to |
|---|---|---|---|
| uPVC | 10 to 20 years typical (MyBuilder, 2026); 20 to 40 for high quality (Plastic Centre) | Wash; inspect joints about every five years | Modern and mid-century houses outside protected areas |
| Timber | Depends on paint and position | Repaint on a cycle; repair rot in sections | Period and listed houses; conservation areas |
| Aluminium | Depends on coating and fixings | Wash; watch the joints | Extensions and contemporary houses; dark colours |
On cost, MyBuilder's 2026 guide gives £80 to £150 per metre for a replacement fascia and £100 to £180 per metre for a soffit. It does not split those by material, so treat the range as a guide. Coloured, wood-effect and aluminium boards tend to sit towards the top of it.
What we ask at the survey
We ask what is behind the board, how the house is protected, and how often you intend to look at it. Where the choice is close, the written quote can show two options for the same length, which puts the difference in pounds next to the difference in appearance. If your boards are sound and only worn on the face, capping may be an alternative; the fascia capping guide weighs it up.
