The cost to replace a conservatory roof ranges from £2,000 to £8,000. The price is dependent on the size of the roof, the style and the material.
For example, a glass conservatory roof will cost more than a polycarbonate roof. Similarly, a classic Victorian-style roof will cost more than a lean-to. While it is difficult to give an average, homeowners should set aside around £3,000 to £5,000 for a small to medium-sized roof and £6,000 to £8,000 for a large roof.

Cost to replace conservatory roof
The cost to replace a conservatory roof comes down to the following factors:
- Location: Labour costs vary across the country, with London and the south-east charging more than the north.
- Size of the roof: The bigger the roof, the more materials, labour and time required, resulting in a higher price.
- Style of roof: The style of roof plays a big role in the cost of the work; for example, a lean-to conservatory roof is cheaper than a Victorian or Edwardian style roof.
- Roofing material: The biggest cost driver is the material you opt for. The cheapest material is polycarbonate. Glass is a more expensive choice and roofing tiles are the most costly.
Another cost driver to consider is the company. A large firm with an established reputation will charge more than a small company with fewer overheads and a smaller client base. Moreover, smaller companies are often under the VAT threshold, meaning they don’t add 20% to the cost.
As for roof style, there are three main types of conservatory roof.
- Lean-to: A lean-to is a single slope roof with three straight sides and its upper edge adjoining or ‘leaning’ against an existing house wall.
- Victorian: A Victorian roof is a classic style with a faceted appearance and high, ornate roofs. A typical example will have a bay fronted shape with three or five sides and an angled roof with detailing.
- Edwardian (or Georgian): A classic style roof with a more understated appearance than a Victorian style. The main difference is the square or rectangular design of the Edwardian conservatory.
Polycarbonate conservatory roof
Polycarbonate is the most affordable conservatory roof material. However, the low cost is reflected in its thermal efficiency.
Polycarbonate roofs are renowned for creating an almost uninhabitable environment – being too cold in the winter and too warm in the summer. While its efficiency has been improved upon, it continues to be outperformed by glass or solid options.
Another downside is the loud, disruptive noise it makes during rainfall. Nevertheless, it continues to be a popular choice for a low budget.
|Lean-to||3m x 3m||£2,000 – 2,500|
|Lean-to||4m x 4m||£2,500 – 3,100|
|Lean-to||5m x 5m||£2,700 – 3,300|
|Victorian||3m x 3m||£3,500 – 4,000|
|Victorian||4m x 4m||£4,300 – 5,000|
|Victorian||5m x 5m||£4,600 – 5,300|
|Edwardian||3m x 3m||£3,800 – 4,200|
|Edwardian||4m x 4m||£4,400 – 5,000|
|Edwardian||5m x 5m||£5,000 – 5,500|
Glass conservatory roof
A glass conservatory roof is by far the most popular material – and understandably so. Often referred to as an ‘extension of nature’, it floods the conservatory with natural light, offers an unmatched connection to the outside world and is aesthetically pleasing.
While specialist options are available, including self-cleaning and energy-efficient panels, a standard glass finish will resolve the issues of noise pollution and energy efficiency presented by a polycarbonate roof and offer a room that can be enjoyed year-round. The only real drawback of a glass roof is the price, with it being considerably more expensive.
|Lean-to||3m x 3m||£2,600 – 3,100|
|Lean-to||4m x 4m||£3,000 – 3,500|
|Lean-to||5m x 5m||£4,000 – 4,500|
|Victorian||3m x 3m||£4,500 – 5,000|
|Victorian||4m x 4m||£4,800 – 5,300|
