Summary
Fascia, soffit and gutter renewal ("FSG") is high-volume work for roofers, carpenters and small builders. The customer perception is "just replacing some boards", but the job involves access (scaffold/tower), proper stripping of existing materials (which may contain asbestos in pre-2000 buildings), correct over-fascia vent provision for roof void ventilation, and lead-free, weatherproof gutter joints.
The single biggest pricing trap is quoting per linear metre on the assumption that everything is straightforward, then finding rotted rafter feet, blocked gutter outlets, or that the existing soffit is asbestos cement on a 1960s property. Always do a measure-up site visit and lift the existing soffit at one corner to check what's underneath.
The second pricing trap is "capping over" — overcladding existing rotten timber with UPVC. It looks neat and saves a day's labour but traps moisture, accelerates rot, and is the source of most "the new fascia is failing already" callbacks. Quote full strip-and-replace as standard; offer overcladding as a clearly-flagged budget option.
Key Facts
- Fascia — the vertical board at the eaves where the gutter is fixed, covering the ends of the rafters.
- Soffit — the horizontal board on the underside of the eaves overhang.
- Bargeboard — the angled board on the gable end (not strictly fascia, but usually replaced at the same time).
- Drip / fillet board — narrow board behind the fascia, in some designs.
- Roofline materials — UPVC dominates (>80% market). Other options: aluminium, fibre cement, timber.
- UPVC thickness — fascia 18mm minimum (replacement), soffit 9-10mm.
- Soffit width — typically 200mm, 250mm or 300mm to match overhang.
- Over-fascia vent — required when replacing fascia to maintain Part F roof void ventilation (10mm continuous slot equivalent).
- Asbestos risk — soffits in 1950s-1980s housing may be asbestos insulating board (AIB) or asbestos cement. Test before stripping (CAR 2012 duty).
- Ventilation requirement — minimum 10mm continuous opening at eaves for cold roofs (BS 5250). Achieved via over-fascia vent or soffit vent strips.
- Roofing felt — old felt usually replaced or extended over new fascia with a felt support tray ("Eaves Support Tray") to direct water into the gutter.
- Gutter sizing — domestic standard 112mm half-round or 110×80mm square. Bigger houses often need 125mm or deep-flow.
- Downpipe sizing — 68mm round or 65mm square standard. One downpipe per 25m² roof catchment area minimum.
- Fixings — stainless steel or polymer-coated nails/screws. Galvanised steel fails within 5 years.
- Lead flashing interface — fascia replacement must respect existing lead flashings into the wall; lift, clean, redress.
- Scaffold or tower — required for safe working above 2m (Working at Height Regulations 2005). Tower hire £80-£150/day; scaffold £400-£1,200 for a typical house.
- Warranty — 10-year manufacturer guarantee on UPVC profiles standard from major brands.
- Lifespan — UPVC fascia/soffit 25-35 years with annual gutter clearing.

Pre-quote site visit checklist
SITE VISIT CHECKLIST — FASCIA/SOFFIT
====================================
□ Property age — pre-2000 = asbestos risk
□ Existing material — timber, asbestos, UPVC
□ Lift one section of soffit to inspect rafter feet
□ Check gutter falls, joints, current performance
□ Measure linear metres (separate eaves vs gable)
□ Check eaves height for access (scaffold vs tower)
□ Check for lead flashings, leadwork interface
□ Roof felt condition — overhanging, holed, sagging
□ Solar panels / TV aerial / satellite — relocation cost
□ Boxed-in soffits hiding cables, vents, lights
□ Number of downpipes and discharge points
□ Tree overhang — annual gutter clearing implication
A 30-minute site visit prevents 80% of post-quote disputes.
Pricing model
Most installers price per metre supplied-and-fitted, with line items for access and extras:
| Line | Price |
|---|---|
| Fascia, soffit and gutter, supplied and fitted per linear metre | £40–£75 |
| Bargeboard per metre (often higher per-m than eaves due to access) | £55–£90 |
| Lifting and replacing roof tiles to install support trays (per m) | £10–£15 |
| Scaffolding (where required) | £400–£1,200 |
| Asbestos removal (per linear m of asbestos soffit) | £35–£70 |
| Waste removal and skip | £180–£350 |
| Removing/refitting solar PV panels | £200–£400 |
For a typical 3-bed semi: 25m eaves + 8m gable = 33m × £55 = £1,815 + £600 scaffold = £2,415.
Labour day rates
| Crew | Day Rate (2026) | Productivity |
|---|---|---|
| Roofer + labourer | £450–£650 | 15-20m fascia/day on a typical job |
| Specialist roofline gang (2-man) | £550–£800 | 25-35m/day with prepared scaffold |
| Subcontracted roofliner (per metre rate) | £25–£35/m labour-only | Variable productivity |
A semi-detached house typically takes 1.5–2.5 days for a 2-person crew.
Where the margin sits
- Materials markup — 30–50% on UPVC profiles, brackets, fixings. Customers won't price-compare these.
- Day rate — full day rate, never hour-based. Access setup eats half the morning regardless of job size.
- Access — scaffold hire often passed at cost-plus-15%; this is a soft markup that doesn't trigger complaints.
- Asbestos disposal — high-margin line. Charge correctly for licensed disposal.
- Aftercare — annual gutter clearing contract at £80–£140/year is recurring revenue.
Asbestos awareness
Soffits in housing built between 1950 and 2000 may contain:
- Asbestos cement (AC) soffits — most common. Lower-risk material but still requires controlled handling under CAR 2012.
- Asbestos insulating board (AIB) soffits — higher-risk, must only be removed by a licensed contractor under HSE notification.
- AC gutters — rare but seen in older properties.
If suspected, do not strip. Send a sample to a UKAS-accredited lab (£20-£40 turnaround) and quote the disposal route based on the result. Never use power tools on suspected asbestos materials — wet stripping by hand only.
Common quote-padding errors that lose work
- Adding scaffold to every quote when a tower would do — for single-storey or simple two-storey, an alloy tower is often adequate and £600 cheaper.
- Pricing for over-fascia vent on jobs that already have soffit vents — duplicates ventilation, not required.
- Quoting bargeboards as eaves rate — gable access is harder; price separately.
- Forgetting bracket replacement — old timber brackets often fail with new gutters; allow £80–£140 in fixings.
Common quote-cutting errors that cause callbacks
- Capping over rotten timber — saves a day, fails in 3-5 years. Don't.
- Reusing old gutter brackets — old timber brackets in rotten fascia will fail.
- Skipping over-fascia vent — blocks roof ventilation, causes condensation in the void, customer calls back about damp.
- Stainless steel nails replaced with galvanised — galvanised fails in 5-7 years; cost difference is £30 a house.
Frequently Asked Questions
Do I need scaffold or will a tower do?
For most 2-storey houses, an alloy tower (working platform 4-5m high) is adequate and saves £400-£700 vs full scaffold. Scaffold is required where: roof pitch makes leaning over the fascia unsafe, the eaves height is over 6m, the gable ends are inaccessible from a tower, or the property is on a slope. Always check the access decision is supported by a Working at Height Regulations 2005 risk assessment — and document it in the job pack.
What if the customer's existing soffits contain asbestos?
Stop work. Tell the customer immediately. Get the soffit tested by a UKAS lab (£20-£40 per sample). If positive for asbestos cement, plan removal under CAR 2012 with water suppression, full PPE, double-bagged disposal at a licensed transfer station. If positive for AIB, hand off to a licensed asbestos removal contractor — you cannot legally remove AIB without a license. Add £35-£70 per metre to the quote for the disposal route, and provide the customer with the consignment note.
Do I need to notify Building Control?
In isolation, no — fascia/soffit replacement is not notifiable. But if the work involves any roof structure modification (new bargeboards on a new gable, alteration to roof ventilation, lifting a section of tiles for new felting), Building Control may apply. Notify when in doubt — a Building Notice is cheap insurance against an enforcement notice.
How do I ventilate the roof void with the new fascia?
Use over-fascia vent strips — these provide a 10mm continuous opening between the fascia top edge and the roof tile. Required by BS 5250 to prevent roof void condensation. Alternative: soffit vent strips (usually 25mm continuous) in the soffit instead. Either is acceptable; over-fascia is now more common because soffit vents are visible from below.
Should I include gutter clearing in the quote?
For the install year, yes — clearing within 12 months should be included. After that, offer an annual contract at £80-£140 depending on property height. This is the most repeatable trade work in the FSG sector — every house needs clearing every 12-18 months. Customers who paid you to install will usually take the maintenance contract if you offer it at install time.
