Why homeowners replace conservatory roofs
Many conservatories become uncomfortable to use after a few years. Glass and polycarbonate roofs lose heat in winter, let in too much heat in summer, and often suffer from leaks or condensation. For these reasons, many homeowners look at roof replacement as a way to improve comfort and extend the life of their conservatory.
Average cost of a new conservatory roof in the UK
The cost of a new conservatory roof in the UK usually falls between £2,000 and £12,000, depending on the type of roof and the size of the structure. A small lean-to roof is at the lower end of the range, while larger or more complex designs cost more. The choice of material also has a strong influence on price.
Type of roof material and cost differences
- Polycarbonate: The cheapest option, but poor insulation often makes it a short-term fix.
- Glass: Offers better light and appearance but still loses heat quickly.
- Solid insulated panels (such as Cosy Panels): Mid-range cost with strong year-round insulation and minimal disruption during fitting.
- Tiled or solid roofs: The most expensive but can make the conservatory feel more like a full extension.
Each option has its own balance of cost, comfort, and durability.
Size and style of the conservatory
The larger the conservatory, the more material and labour are needed, which increases the cost. Style also plays a role. A simple lean-to is more affordable than an Edwardian or Victorian roof with multiple slopes. Bespoke shapes or unusual frames may add to the price as panels or tiles must be custom-made.
Insulation and energy efficiency considerations
Although better insulation increases the upfront price, it can reduce energy bills over time. A poorly insulated roof allows heat to escape, making the conservatory costly to heat in winter. Solid insulated panels can provide a balance of cost and performance by lowering energy use while keeping the space comfortable throughout the year.

Labour and installation factors
Labour costs depend on how complex the installation is. A straightforward panel replacement may take a few days, while a full tiled roof may take longer. Access to the property also matters. If scaffolding or extra equipment is required, this may add to the overall cost.
Planning permission and regulations
In most cases, replacing a conservatory roof does not require planning permission, but some exceptions exist. For example, changing to a solid tiled roof could affect building regulations. Homeowners should check with their local authority to avoid unexpected costs or delays.
Long-term value versus upfront cost
It can be tempting to choose the cheapest option, but a roof that does not perform well may lead to ongoing heating bills, condensation, or the need for another replacement. Considering the long-term value helps ensure that the conservatory remains a useful part of the home rather than an underused space.
Getting a tailored quote
Every conservatory is different, so the most accurate way to understand cost is to arrange a tailored quote. This will take into account the size, style, existing structure, and choice of material.
