We take a look at conservatory roof replacement costs based on the most popular designs and sizes below.

Lean to conservatory roofs

This is the UK’s most popular type of conservatory and no wonder as it’s usually the least expensive style available, and these conservatories balance space, light, and comfort with a compact and elegant design.

On a straight-forward installation, a lean to conservatory roof replacement should cost you between £2,050 and £3,150 on typical standard-sized conservatories.

Edwardian Conservatory Roofs

Edwardian conservatories’ pitched apex roof give a sense of both style and space with a classic style that works well even though a conservatory might only be a decade or two old. This timeless and aesthetically-pleasing style is popular for large homes and period properties.

For an Edwardian conservatory roof replacement, a budget of between £3,350 and £7,400 would be realistic on the most widely-installed sizes depending on whether you’re choosing a glass conservatory roof or a polycarbonate conservatory roof.

Victorian Conservatory Roofs

The most popular of the larger conservatory styles, Victorian conservatories look great on new builds and old properties. Benefitting from a bay window, they create a panoramic vista and are superb at visually framing your back garden.

If you’re looking for a Victorian conservatory roof replacement, you should budget between £3,350 and £6,950 depending on the size and whether you want a glass roof or a polycarbonate roof.

Georgian Conservatory Roofs

Georgian conservatories are one of the UK’s five most popular types of conservatory installation. Square or rectangular in form, Georgian conservatories feature an elegant pitched roof with three or four sides. Expect to pay between £3,350 and £7,440 for a Georgian conservatory roof replacement although the price will go higher for larger installations.

Gable-fronted conservatory roofs

Gable-fronted conservatories feature a beautiful apex roof with multiple panes of glass which slope seamlessly and elegantly towards the top of the structure. The minimal detailing and lack of fussiness makes these conservatories feel much bigger than they actually are.

Quotes for standard size gable-fronted conservatory roof replacements will generally vary between £3,400 and £7,400 depending on the size and your choice of roof material.

Double Hipped Conservatory Roofs

Double-hipped conservatories avoid the characteristic sloped roof of lean to conservatories and feature a symmetrical design that slopes on all sides. Popular for both contemporary and traditional properties, double-hipped roofs offer an open appearance whilst maximising natural light.

Expect quotes of between £3,850 and £7,850 from your installers for a double hipped replacement for your existing roof.

Lantern Conservatory Roofs

Lantern conservatory roofs offer a statement feature to any home with stylish glass walls and a lantern-shaped sloping roof finish. There are numerous styles and designs to choose from plus this type of roof offers a level of personalisation so homeowners can really create something unique.

Lantern conservatory roof replacements will vary more than other types of conservatory because of the additional costs due to the high degree of personalisation available. However, typical costs vary from £3,850 to £7,800.

What Other Factors Influence How Much It Will Cost For Conservatory Roof Replacement?

Size isn’t everything when it comes to the cost of replacing a conservatory roof. The cost of your conservatory roof will vary depending on the size but there are other factors which can influence what you pay.

You may decide energy efficiency is high on your list of priorities with rising energy bills and opt for a more expensive glass that offers better thermal efficiency.

There are other types of glazing upgrades which may not have been available when your current conservatory was installed. These include self-cleaning glass and glass with special sound insulation technology, ideal if your home is in a busy area with a lot of external noise. Triple glazing is the glass of choice for many people with the savings you can make on energy bills well worth the additional costs.

If you decide you would like a solid conservatory roof instead of your existing double glazed roof, then you may need to strengthen the foundation of the structure; this will increase the labour costs. However, even if your new conservatory roof is higher than the average price in our tables, you can be absolutely certain that it’s going to be cheaper than the cost of replacing your entire conservatory.

Comparing Conservatory Roof Prices

Replacing a conservatory roof doesn’t need to be expensive. A polycarbonate conservatory roof will be the cheapest of all the conservatory roofs, with glass roofs coming in next and a solid roof generally being the more expensive.

Tiled conservatory roof cost can skyrocket depending on the design and type of tile used for a solid conservatory roof. When replacing a roof on a conservatory, you need to consider roof style and materials besides just the size.

Supalite Tiled Conservatory Roof

Our guide tables above give average prices for different types and sizes of conservatory roofs. Typically the roof is built from scratch mainly on site by your installation company on top of your conservatory’s existing structure. Supalite offers something different. Supalite conservatory roofs are actually built in the company’s factory and delivered as a whole unit to your property.

Many roof replacement projects require that part of your existing conservatory is dismantled and the structure is remodelled and strengthened to cope with the weight of a new roof. Supalite is designed to be so lightweight that no other modification to your existing conservatory is needed. It takes a lot less time to install a Supalite roof which will save money on labour costs compared to almost any other type of conservatory roof replacement.

Supalite roofs can be installed on lean to, gable, Victorian, P-shaped, Edwardian, or double-hipped conservatories. The installation company you choose takes precise measurements for your replacement conservatory roof and then sends them to the Supalite factory for production. Who knew that replacing a conservatory roof could be so easy!

Growing rapidly in popularity, Supalite offers many advantages to homeowners including:

• superb noise and temperature insulation with impressive thermal efficiency
• a 20-year guarantee as standard
• tiles available in a choice of colours to match or contrast with the walls and roof of your home
• plenty of natural light with unlimited skylights
• reduced costs to heat your conservatory
• external and internal lighting options
• external flashing if required
• fully compliant with Building Regulations.

Standard Tiled Conservatory Roofs: Prices By Size

Another option is a traditional tiled conservatory roof replacement; like the glass and polycarbonate roof options, the construction and placement of the roof is done on site. For most standard installations of this type, the average conservatory roof cost would range from £7,250 to £19,200.

Bear in mind that, depending on the age and construction of your conservatory, the frame may need to be strengthened to support the weight of a solid roof, increasing the figures in this table.

There are three types of tile you can choose for your replacement conservatory roof:

• Concrete – the heaviest of the three options and your tiles actually become heavier over time because the concrete absorbs rainwater. There is a wide range of styles and colours available for you to choose from so make sure you ask your installer to see their suppliers’ catalogues.
• Slate – slate looks stunning but it is a very expensive option. Synthetic slate tiles have recently been introduced to the market for homeowners looking for an attractive roof on a budget so check out whether your installer can offer both natural and faux slate options to achieve the look without the price tag.
• Composite tiles – the cheapest of the three options, composite tiles are available in a wide selection of different colours and they’re very light so your conservatory won’t usually require any additional structural work compared to some other tiled roof options.

The main benefits of installing a tiled conservatory replacement roof are:

• condensation reduction – tiled conservatory roofs provide much greater protection against condensation thanks to the multiple layering which lies between the tiles and the new ceiling of your conservatory.
• energy bill savings – a tiled conservatory roof is up to 10 times more energy efficient than a conservatory with a glass or polycarbonate roof, according to the latest industry tests.
• noise insulation properties – many homeowners find it too noisy to sit in a conservatory with a glass or polycarbonate roof when it’s hailing or raining outside. This, and nearly every other outside noise, is no longer a problem with a tiled roof.
• rooflights – less light will get into your conservatory with a tiled roof but one or more rooflight installations will mitigate the loss of light greatly. Even without rooflights, industry tests have shown that a conservatory with a tiled roof receives 95% of the light that a conservatory with a glass or polycarbonate roof receives.

Should my installer belong to certain trade bodies?

Whether you choose a polycarbonate, glass, tiled, or Supalite conservatory replacement roof, we strongly recommend that you only work with companies approved by one or both of the following:

• The Fenestration Self-Assessment Scheme (FENSA)
• Certification and Self-Assessment (CERTASS)

Do I need planning permission from the council for my replacement conservatory roof?

Conservatory roof replacements are generally considered as permitted developments under the Building Regulations code. Unless your home has recently been listed or you live in either a Directive 4 area or a conservation area, you will probably not need planning permission for a polycarbonate, glass, tiled, or Supalite conservatory replacement roof.

However, it is always best to speak with the local authority’s Planning Department prior to committing to any work with your installer.
