Polycarbonate conservatory roof prices by size

The cost of a replacement polycarbonate roof for your conservatory depends on a few factors, but is mostly determined by the shape and size of your conservatory roof and the style of polycarbonate roof your choose.

Lean to conservatory roofs

This is Britain’s most popular type of conservatory. That’s not only because it’s the least expensive style available but because lean to conservatories balance space, light, and comfort with a compact and elegant design.

Given this name because the roof “leans to” the edge of the sides of your conservatory, these “sun rooms” or “garden rooms” are ideal for those where price and value are strong considerations.

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

Edwardian conservatory roofs

For an Edwardian conservatory roof replacement, a budget of between £3,350 and £7,400 would be realistic on the most widely-installed sizes.

Victorian conservatory roofs

The most popular of the larger conservatory styles, Victorian conservatories look great on new and old homes. Benefitting from a bay window which lends the view outside a panoramic, widescreen feel, they’re superb at visually framing your back garden and all the effort you’ve put into making it look perfect.

Gable-fronted conservatory roofs

Gable-fronted conservatories are sometimes known as “pavilion conservatories” because of the sweep and the length of the installation at the back of a home. Featuring a beautiful apex roof comprising multiple panes of glass which slope seamlessly and elegantly towards the top of the structure, its minimal detailing and lack of fussiness makes these conservatories feel much bigger than they actually are.

Supalite tiled conservatory roof

Unlike the quotes above where your roof is built from scratch mainly on site on top of your conservatory’s existing structure, Supalite offers something different. Your Supalite conservatory roof is 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 demolished and that the structure of it 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 than any other type of conservatory roof.

Supalite roofs can be installed on lean to, gable, Victorian, P-shaped, Edwardian, or double-hipped conservatories. The installation company you choose to do the work will take all the precise measurements needed for your replacement roof and then send them back to the Supalite factory for production.

Growing in popularity, some of Supalite’s biggest advantages to homeowners are:

  • superb noise and temperature insulation,
  • 20 year guarantee as standard,
  • tiles available in a choice of slates and colours (perfect for matching to your existing wall and house roof),
  • it lets in lots of light (you can choose as many skylights as you want for your installation),
  • it will cost less to heat your conservatory,
  • external and internal lighting options,
  • external flashing if required,
  • fully compliant with Building Regulations.

Standard tiled conservatory roof prices by size

You can also choose to go for the more traditional standard tiled conservatory roof replacement option where, like with the glass and polycarbonate options, the construction and placement of the roof is done on site. For the most standard installations of this type, you would look to pay between £7,250 and £19,200.

Please bear in mind that, depending on the age and construction of your conservatory, that the frame may need to be strengthened to support the weight of the new roof. This may increase the ballpark figures quoted in the table just above.

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 working on a budget, so do ask your installer if you’d like that particular look for your home.
  • composite tiles – the cheapest of the three options, composite tiles are available in a wide selection of different colours and they’re very light.

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 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:

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 unless where you live has been declared 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 any installer.
