How Much Does Roofline Replacement Cost? (2026 Prices)
A full roofline replacement — fascia, soffit, and guttering — on a typical UK three-bedroom semi-detached house costs between £2,000 and £4,000 in 2026, with the average sitting around £2,800. This includes PVC-U materials, scaffolding, labour, and waste disposal. The biggest variables are the size and complexity of the property, the scaffolding requirement, and whether you are also replacing bargeboards and cladding on gable ends. For bungalows, expect £1,500–2,800. For large detached properties, £3,500–6,000+.
Roofline replacement is one of the best-value home improvements available. It transforms the kerb appeal of a property overnight, eliminates painting and maintenance for 30+ years, protects the roof structure from weather damage, and typically pays for itself through reduced maintenance costs within 8–10 years.
2026 Price Breakdown by Component
Materials
| Component | Price Per Metre | Full House (3-bed semi, ~24m gutter, ~30m fascia/soffit) |
|---|---|---|
| Fascia boards (200mm, 16mm white) | £5–9 | £150–270 |
| Soffit boards (300mm, white) | £5–8 | £150–240 |
| Guttering (112mm half-round + fittings) | £6–10 (system) | £150–250 |
| Downpipes (2 × 68mm, full run) | £5–8 per pipe | £40–80 |
| Bargeboards (if applicable) | £5–9/m | £50–90 |
| Trims, joints, fixings | — | £60–120 |
| Anthracite grey premium | +10–15% | +£50–100 |
| Materials subtotal | — | £600–1,050 |
Labour
| Task | Typical Cost |
|---|---|
| Roofline replacement (2-person team, 1–2 days) | £800–1,600 |
| Additional day for complex roofline | £400–800 |
Scaffolding
| Property Type | Scaffolding Cost |
|---|---|
| Bungalow (may not need scaffolding) | £0–300 |
| Two-storey semi (front and back) | £400–800 |
| Two-storey detached (all four sides) | £600–1,200 |
| Three-storey or complex roofline | £800–1,500+ |
Scaffolding is often the single largest cost in a roofline replacement. It also dictates the project timeline — scaffold goes up, work happens, scaffold comes down. The hire period is typically 1–2 weeks, and overstaying that window attracts additional weekly charges.
Total Cost by Property Type
| Property | Materials | Labour | Scaffolding | Total |
|---|---|---|---|---|
| Bungalow | £350–650 | £500–1,000 | £0–400 | £1,500–2,800 |
| Terraced (2-storey, front only) | £200–400 | £400–700 | £250–500 | £850–1,600 |
| Semi-detached (2-storey) | £500–900 | £800–1,400 | £400–800 | £2,000–3,500 |
| Detached (2-storey) | £700–1,200 | £1,000–1,800 | £600–1,200 | £2,800–4,500 |
| Large detached (4+ bed) | £900–1,600 | £1,200–2,200 | £800–1,500 | £3,500–6,000 |
| Dormer bungalow | £600–1,000 | £800–1,400 | £400–800 | £2,200–3,800 |

What Affects the Price?
Property Size and Complexity
The total linear meterage of fascia, soffit, and guttering is the primary cost driver. A simple rectangular house has four straight runs. A property with bay windows, dormers, multiple roof levels, or a complex L-shaped plan has many more metres and many more fittings, angles, and cuts. Corner-plot properties where three or four elevations are publicly visible tend to have higher costs because homeowners typically want every elevation finished to the same standard.
Access Difficulty
- Standard two-storey house on flat ground → straightforward scaffolding
- House on a slope → specialised scaffolding or extra time
- Conservatory or extension blocking access → additional scaffold sections
- Trees or overhead wires → extra precautions and cost
- Narrow side passages between semi-detached pairs → may need alternative scaffold configurations
Material Choices
| Choice | Impact on Cost |
|---|---|
| White PVC-U (standard) | Baseline |
| Anthracite grey or black | +£50–100 materials |
| Woodgrain (rosewood, oak) | +£50–100 materials |
| Deep-flow or hi-cap guttering | +£50–150 materials |
| Cast-iron-effect guttering | +£80–200 materials |
Kalsi Plastics manufactures a comprehensive roofline range including fascia boards, soffit boards, bargeboards, and all associated accessories. All boards feature through-colour pigmentation and UV stabilisation for genuine long-term performance without fading.
Condition of the Existing Roofline
If the timber rafters behind the fascia are rotten, they need repairing before new PVC can be fitted. This adds labour time and timber costs:
- Minor rafter repairs (1–3 rafter ends): +£100–300
- Extensive rafter repairs (half or more need work): +£300–800
- Full rafter-end replacement (rare, major structural issue): +£500–1,500
A good installer will inspect the timber once the old fascia boards are removed and report any issues before proceeding. This is worth clarifying in the initial quote — ask whether the quote includes for minor rafter-end repairs or whether they will be charged as extras.
Regional Variation
Labour rates vary across the UK:
| Region | Labour Cost Index |
|---|---|
| London and South East | 120–140% |
| Midlands | 100% (baseline) |
| North West | 90–100% |
| North East and Scotland | 85–95% |
| Wales | 85–95% |
| South West | 100–110% |
What’s Included in a Typical Quote?
A reputable installer’s quote for roofline replacement should include:
- ✅ Removal of existing timber fascia, soffit, and guttering
- ✅ Inspection and minor repair of rafter ends
- ✅ Supply and fitting of new PVC-U fascia boards
- ✅ Supply and fitting of new PVC-U soffit boards (vented where required)
- ✅ Supply and fitting of new PVC-U guttering and downpipes
- ✅ All trims, joints, corners, and fixings
- ✅ Waste disposal (old timber and guttering)
- ✅ Scaffolding (or clearly stated as separate)
Watch Out For
- ❌ Scaffolding quoted separately and at inflated prices
- ❌ “Extras” for rafter repairs not mentioned upfront
- ❌ No mention of ventilation (vented soffit) — a red flag for compliance
- ❌ Very low quotes that use 9mm capping board over rotten timber instead of proper replacement
- ❌ No written guarantee on materials and workmanship
Capping vs Full Replacement
One important distinction: capping means fitting thin PVC boards over the existing timber, while full replacement means removing all old timber and fitting new, thicker PVC-U boards directly to the rafter ends. Capping is cheaper (roughly 30–40% less) but carries risks:
- Hidden rot behind the capping worsens unseen
- Capping boards are thinner (typically 9 mm vs 16–18 mm for full replacement)
- Less durable in strong winds
- Does not address underlying structural issues
Full replacement with quality fascia boards is the industry-recommended approach for any property where the existing timber is more than 15–20 years old. The modest extra cost buys genuine long-term protection.
DIY vs Professional: Is It Worth the Saving?
| Factor | DIY | Professional |
|---|---|---|
| Materials cost | £500–1,000 | £500–1,000 (same) |
| Scaffold tower hire | £100–200 (1 week) | Included in scaffolding |
| Full scaffolding | — | £400–1,200 |
| Labour | Your time (2–4 days) | £800–1,800 |
| Guarantee | None | Typically 10–20 years |
| Insurance | Your own home insurance | Installer’s public liability |
| Total | £600–1,200 | £2,000–4,500 |
The DIY saving is roughly £1,400–3,000 — significant. But it requires:
- Confidence working at height for extended periods
- Basic carpentry skills
- Time (a full weekend minimum for one elevation)
- Your own insurance cover if something goes wrong

How to Get Value for Money
1. Get Three Quotes
Always get at least three quotes from different installers. Specify exactly what you want (full replacement, not capping; vented soffit; specific colour) so quotes are comparable.
2. Bundle Guttering with Roofline
Replacing guttering at the same time as fascia and soffit adds minimal cost (the scaffolding is already there, and the gutter has to come off anyway). Doing it separately later means paying for scaffolding twice.
3. Choose a Reputable Manufacturer
Cheap PVC boards may save £50–100 but risk early failure, colour fade, and brittleness. Kalsi Plastics’ roofline range is manufactured in the UK with UV stabilisation and through-colour pigmentation for genuine long-term performance.
4. Consider the Full Roofline
While the scaffolding is up, consider also replacing bargeboards, window trims, and any cladding on gable ends. The incremental cost is modest compared to the savings on a future separate scaffold hire.
5. Off-Peak Discounts
Autumn and winter are quieter for roofline installers. You may get better prices and faster availability than during the busy spring/summer season.
6. Use the Kalsi Roofline Calculator
Our roofline calculator helps you estimate material quantities for your specific property — useful for checking installer quotes and ensuring nothing has been missed.
Frequently Asked Questions
How much does new fascia and soffit cost?
For a typical three-bedroom semi-detached house in 2026, expect £2,000–3,500 for a full roofline replacement including fascia, soffit, guttering, scaffolding, and labour. Bungalows are cheaper (£1,500–2,800) and large detached houses are more expensive (£3,500–6,000+).
Is roofline replacement worth it?
Yes. PVC-U roofline eliminates painting (saving £500–1,000 every 5–7 years), protects the roof structure from water damage, and significantly improves kerb appeal. Most installations pay for themselves in reduced maintenance within 8–10 years, and then save you money for the remaining 20+ years of their life.
How long does roofline replacement take?
A professional two-person team typically completes a standard semi-detached house in 1–2 days. Larger or more complex properties may take 3–4 days. Add half a day each for scaffold erection and dismantling.
Should I replace fascia and soffit at the same time?
Absolutely. The soffit has to be disturbed to replace the fascia anyway, and the cost of the soffit boards is a small fraction of the total project. Replacing both ensures a consistent appearance and eliminates the risk of old soffit boards failing shortly after new fascia is fitted.
Can I get roofline replacement on finance?
Many installers offer finance options (0% interest for 12 months, or low-rate over 3–5 years). Check that the finance is from a regulated provider and compare the total cost including interest with a cash payment.
What is the difference between capping and full replacement?
Capping fits thin PVC boards over existing timber; full replacement removes the timber and fits thicker boards directly to the rafter ends. Full replacement costs 30–40% more but addresses hidden rot, uses more durable boards, and provides a better long-term result. Full replacement is recommended on any property where the existing timber is deteriorating.
