How Much Replacement Conservatory Roof Cost by Roof Type
The biggest factor influencing cost is the type of roof you choose.
Polycarbonate Roof Replacement
Polycarbonate roofs are the cheapest option and are often chosen for budget upgrades.
-
Typical cost: £2,000–£5,500
-
Pros: Affordable, lightweight, quick to install
-
Cons: Poor insulation, noisy in rain, shorter lifespan
This option is best if cost is your main concern and you mainly use the conservatory seasonally.
Glass Conservatory Roof
Glass roofs are a popular mid-range choice, offering more light and better temperature control.
-
Typical cost: £3,000–£8,000
-
Pros: Bright interior, improved thermal efficiency, modern appearance
-
Cons: More expensive than polycarbonate, can still overheat without solar control glass
Modern glazing options significantly improve comfort compared to older glass roofs.
Solid or Tiled Conservatory Roof
Solid and tiled roofs are the most expensive but also the most transformative.
-
Typical cost: £5,000–£15,000+
-
Pros: Excellent insulation, quieter, makes the conservatory feel like a true extension
-
Cons: Higher upfront cost, may require structural assessment
If you want year-round usability, this option often delivers the best long-term value.
Key Factors That Affect the Final Price
When asking how much replacement conservatory roof cost in practice, several variables come into play.
Size and Shape
Larger conservatories require more materials and labour. Complex designs such as Victorian, Edwardian, or bespoke shapes increase costs compared to simple lean-to structures.
Structural Requirements
Some roof types, especially tiled systems, may require additional strengthening of the existing frame. This can add to labour and material costs but is essential for safety and compliance.
Insulation and Energy Performance
Higher-performance insulation increases upfront cost but improves comfort and reduces heating bills. Many homeowners see this as a worthwhile investment.
Labour and Installation
Labour costs vary depending on location in the UK and the complexity of the job. Experienced installers may charge more, but quality workmanship can prevent future issues.
Optional Extras
Features such as roof vents, skylights, internal plastered ceilings, or integrated lighting can all increase the final price.
Is Replacing a Conservatory Roof Worth the Cost?
For many homeowners, replacing the roof is far cheaper than building a new extension and delivers excellent results. A well-insulated roof can:
-
Make the conservatory usable all year
-
Reduce heating and cooling costs
-
Improve noise reduction
-
Increase property appeal and resale value
If your existing frames and base are in good condition, roof replacement is often a cost-effective upgrade.
So, how much replacement conservatory roof cost in the UK? In most cases, homeowners should expect to pay anywhere from £2,000 to £15,000+, depending on roof type, size, and specification. While budget options exist, investing in better materials and insulation often pays off in comfort, energy efficiency, and long-term value.
Choosing the right roof isn’t just about price — it’s about how you want to use your conservatory and how long you plan to stay in your home.
