How to Price Fascias, Soffits and Guttering Replacement: uPVC, Aluminium and Wood

Quick Answer: A complete UK roofline replacement (fascias, soffits, bargeboards, guttering and downpipes) on a 3-bed semi typically costs £2,800–£5,500 in 2026, fitted in uPVC. Aluminium upgrades add 25–40%; cedar or hardwood adds 60–100%. Material costs are roughly £20–£35 per linear metre uPVC fascia + soffit; £75–£150/m aluminium; £45–£90/m cedar. Labour is £200–£350 per day per fitter, with a typical 3-bed taking 2–3 days plus scaffold. BS 7619 / BS 6915 covers timber roofline; uPVC products typically work to BBA-certified manufacturer specs.

Summary

Roofline (fascias, soffits, bargeboards, gutters, downpipes) is one of the most common refurb jobs because uPVC products from the 1990s and 2000s are now reaching end-of-life. Discoloration, cracking, brittleness in cold weather, and gutter joint failure are the typical drivers. Customers frequently ask "just replace the gutters" but a sound quote covers fascias and soffits at the same time — the real labour cost is the scaffold and ladder access, and doing only gutters means doing it again in 5 years for the rest.

The product split has changed in the last decade. uPVC remains the volume leader (60%+ of UK roofline) because it's cheap, low-maintenance and weather-resistant. Aluminium roofline (especially seamless aluminium gutters formed on site) has grown rapidly — better aesthetics, longer life, eligible for higher-end aesthetic on extensions and architect-led builds. Cedar fascias and hardwood roofline remain niche, mostly heritage and conservation work.

Quoting accurately requires three measurements: total fascia run (linear m), bargeboard run (gable ends), and downpipe count and route. Soffits follow fascia length and depth (typical 200–250 mm). Add 10% for waste and trim. The single most-missed cost is the scaffold; a two-storey UK semi needs 1–2 days of edge-protection scaffold (£500–£1,200), not "we'll work off ladders".

Detailed Guidance

Scope Definition: What's Included

A "full roofline" job typically includes:

  1. Fascia boards — vertical board behind the gutter
  2. Soffit — horizontal underside of the eaves
  3. Bargeboards — fascia equivalent on gable ends
  4. Gutter — half-round, ogee or square, with brackets and joints
  5. Downpipes — verticals connecting gutter to drainage
  6. Hopper heads (where applicable, on ornate or older properties)
  7. Vent insertion — soffit ventilation for roof breath
  8. Strip-out and disposal — old materials to skip/disposal site
  9. Decoration — paint or stain finish for timber roofline

Strip-Off and Make Good

Existing roofline removal needs:

Make-good costs are the variable that catches inexperienced quoters. Always include a £200–£500 contingency for unexpected rot or pest damage.

Installation Sequence

  1. Erect scaffold or edge protection
  2. Remove old gutters and downpipes
  3. Strip old fascias and soffits, dispose to skip
  4. Inspect and repair rafter ends
  5. Install new continuous eaves vent (under fascia top edge)
  6. Install new soffit board (often vented) into rafter housing
  7. Install new fascia boards, fixed through to rafters
  8. Install gutter brackets at 600 mm centres, set to fall (1:600 to outlet)
  9. Hang new gutter sections, joint with sealant gaskets
  10. Install downpipes, fixed to wall with brackets at 1.8 m centres
  11. Connect downpipes to drainage (gulleys, soakaways)
  12. Final visual inspection, leak test with hose

Soffit Ventilation: The Forgotten Detail

A cold roof needs ventilation under the eaves to prevent condensation. Standards:

Without proper eaves ventilation, the loft becomes humid and mineral wool insulation under-performs. Customers complain of "damp loft" or condensation marks on bedroom ceilings — both often traced back to blocked eaves ventilation.

Downpipes and Drainage

Downpipe sizing:

Connection to drainage:

Always inspect existing drainage during a roofline replacement. Blocked or collapsed pipework underground frequently shows up as gutter overflow that customers blame on the new gutter.

Quoting: The Right Way

A defensible quote includes:

  1. Linear metres of fascia, soffit, bargeboard
  2. Number of downpipes and route
  3. Material specification (brand, colour, vented soffit y/n)
  4. Scaffold or access method
  5. Strip-off and waste disposal
  6. Repairs allowance (state contingency)
  7. Soffit ventilation provision
  8. Make-good of any cut-back roof felt
  9. Rainwater drainage tap-in
  10. Decoration finish (if timber) — separate or included
  11. Workmanship warranty period
  12. Programme

A vague quote ("complete roofline replacement, £4,000") leads to disputes. Itemise.

Frequently Asked Questions

Should I quote scaffold or work off ladders?

For two-storey domestic, scaffold is the only legally-compliant access method for the duration of the work (Work at Height Regulations 2005 — see roof safety and edge protection for the full WAH framework). Include the scaffold cost; it's typically £900–£1,800 for a week's hire on a 3-bed semi.

What about asbestos in old soffits?

Some 1960s–80s housing has asbestos cement soffits. Pre-1985 housing is the highest-risk period. If the existing soffits are cementitious, do not disturb without sampling. See asbestos in roofing for survey and removal requirements.

Can I just replace the gutters?

You can — and customers often request this — but if the fascias are 25+ years old uPVC, they're approaching end-of-life. Doing gutters now and fascias in 5 years means a second scaffold cost. Quote both options and let the customer decide; many opt for full roofline once they see the marginal cost difference.

How often should rooflines be cleaned?

uPVC and aluminium need a soft-brush wash with mild detergent twice a year. Gutters need clearing of leaves at least annually (autumn) and after heavy storms. Customers can do this themselves with safe ladder use, or pay £80–£140 annually for a maintenance contractor.

What about colour matching to existing windows?

uPVC roofline is available in matching colours to most uPVC window finishes (white, anthracite grey, black ash, woodgrain). Confirm the customer's window finish (often visible on the rebate) and quote matching products. Aluminium roofline can be powder-coated to RAL number — almost any colour is possible at no premium.
