Conservatory Roof Replacement Cost in 2025: Your Complete Price Guide
Is your conservatory roof leaking, faded, or turning your space into a sauna in summer and an icebox in winter? Replacing it can transform your conservatory into a year-round haven, but costs vary widely depending on materials, size, and labor. In 2025, a new roof might set you back anywhere from £2,000 to £15,000+. This guide covers everything you need to know about conservatory roof replacement costs—polycarbonate, glass, and tiled options—along with installation fees, hidden extras, and tips to maximize value, so you can plan your upgrade with confidence.
Why Roof Replacement Costs Vary
The price of a new conservatory roof depends on the material (polycarbonate, glass, or solid tiles), the size of your conservatory, and structural changes required. A 10m² lean-to with a basic polycarbonate roof might cost £2,000, while a 20m² Victorian with a tiled roof could hit £12,000 or more. Labor rates—higher in cities like London—brand quality, and extras like insulation or skylights also play a role. Let’s explore the options.
Polycarbonate Roof Replacement Costs
Polycarbonate roofs are lightweight, affordable, and let in plenty of light, making them a popular choice for budget upgrades. For a 10m² conservatory, expect costs between £2,000 and £4,000, including installation. Thicker, multi-wall polycarbonate (e.g., 25mm) with better insulation sits at the higher end, especially from brands like Ultraframe.
| Supplier | Average Cost (10m²) | Cost Including Installation |
|---|---|---|
| Wickes | £1,500 | £2,500 |
| Anglian | £1,800 | £3,000 |
| Ultraframe | £2,200 | £3,800 |
Glass Roof Replacement Costs
Glass roofs offer a sleek, modern look with improved insulation over polycarbonate, ideal for all-season use. For a 15m² conservatory, prices range from £4,000 to £8,000, depending on glazing quality (e.g., double or triple glazing, solar control). Premium suppliers like Everest push costs higher with advanced features.
| Supplier | Average Cost (15m²) | Cost Including Installation |
|---|---|---|
| Wickes | £3,000 | £4,500 |
| Anglian | £4,000 | £6,000 |
| Everest | £5,000 | £7,500 |
Tiled Roof Replacement Costs
Tiled or solid roofs turn conservatories into fully insulated, year-round rooms, blending seamlessly with your home. For a 15m² conservatory, costs range from £6,000 to £12,000, including structural reinforcement (often needed for the extra weight). Lightweight tiles or premium systems from Ultraframe can push prices toward £15,000 for larger setups.
| Supplier | Average Cost (15m²) | Cost Including Installation |
|---|---|---|
| SupaLite | £5,000 | £7,500 |
| Guardian | £6,000 | £9,000 |
| Ultraframe | £7,500 | £11,500 |
Hidden Costs to Watch For
Beyond materials and labor, extras can add up. Structural upgrades for tiled roofs (e.g., reinforced frames) might cost £1,000-£3,000. Building regulation approval—required for solid roofs—runs £200-£800, including inspections. Skylights (£500-£1,500) or internal finishing (plastering, lighting, £500-£2,000) boost functionality but inflate the bill. Old roof removal and disposal typically add £200-£500.
Efficiency and Long-Term Savings
A new roof’s insulation impacts energy bills. Polycarbonate offers basic efficiency (U-value ~2.5 W/m²K), while glass (1.6 W/m²K) or tiled roofs (0.18 W/m²K) slash heat loss, saving £100-£300 yearly on heating/cooling. A £10,000 tiled roof might also add £15,000 to your home’s value, far outpacing cheaper options in resale impact.
When to Replace Your Conservatory Roof
Replace your roof if it’s leaking, cracked, or discolored—common after 10-20 years. Polycarbonate fades and brittles; glass can lose seals; old tiles may slip. If your conservatory’s unusable in extreme weather or repair costs rival replacement, act now. A 25-year-old roof is likely past its prime—upgrade before damage spreads.
Final Thoughts on Conservatory Roof Replacement Costs
In 2025, conservatory roof replacement costs span £2,000 to £15,000+, depending on material and size. Polycarbonate suits tight budgets, glass balances aesthetics and efficiency, and tiled roofs offer premium comfort.
