Why Replace A Conservatory Roof?

There are many reasons why people opt to replace their conservatory roof. Some people desire a new roof purely for aesthetic reasons, and others decide on replacing their roof as they want to benefit from the improved insulation and soundproofing qualities certain roofs can provide. No matter what your reason is, we are here to help make the process easier and inform you of all the costs involved.

If you have already done some research, you’ll have noticed that some roofs are considerably cheaper than others. While we understand that the lower-priced roofs may be tempting, they are not always the best option. A roof is the bare minimum requirement for a shelter, so you want to ensure yours is durable, high-quality and protective of the interior. If you make a spur-of-the-moment decision to buy the cheapest roof you can find, you are at risk of receiving a low-quality replacement that could become a financial burden in the future.

How Much Does A Replacement Conservatory Roof Cost?

So, how much does a replacement conservatory roof cost? Below, we have explored the different types of traditional conservatory roofs available and outlined how much you can expect to pay to have them replaced.


Inspired by the architectural style of the Victorian era, Victorian conservatories are one of the most popular styles available as they offer ornate high roofs and a faceted/rounded appearance. Although an aesthetically pleasing quality, the curved structure of this conservatory style means the cost of replacing the roof is higher than other conservatory types. On the rounded side of the conservatory, the roof requires triangular panels, and this additional complication is what makes the replacement slightly more expensive. We would estimate a replacement roof cost for a Victorian conservatory to be anything between £4,345 and £5,005. This is an estimate for a 4m x 4m polycarbonate roof, but of course, the price will vary if you opt for a different type of roof or if your conservatory is larger.


Another period conservatory that still remains to be a popular style for both contemporary and traditional homes today is the Edwardian conservatory. The objective of an Edwardian conservatory is to be a room with clean lines and a regular shape that lets in a significant amount of natural light. Characterised by their pitched roofs, Edwardian conservatories are typically made of 3 sections, which slope upwards from the outer edge and meet at the centre, forming an inverted V shape. This is advantageous as your roof can be as high as you want just by altering the angle of the pitch. Having installed many conservatories in Berkhamsted and the surrounding areas, we know all about the Edwardian style and are able to suggest a practical cost for a roof replacement. For a basic Edwardian polycarbonate roof sized 4m x 4m, you will be looking to pay around £4,480 to £5,120.


Resembling the gable end of a house, gable-fronted conservatories are inspired by Georgian architecture, with the roof being one of its most notable features. This type of conservatory is normally square or rectangular, has minimal detailing and features large glazed sections, which allow for a considerable amount of natural light to enter the room. The roof of a gable conservatory is unique as it consists of two inclined panes which meet in a triangular shape at the front of the structure. The design of the roof varies as some people choose to decorate it with a dramatic sunburst pattern while others opt for simple vertical panels. How you have decided to decorate your roof will impact the replacement cost. For a small-sized gable roof replacement, prices start from around £2,400 and could go up to £5,800, depending on what material you choose.


A P-shaped conservatory combines structural elements from both a lean-to and Victorian conservatory. You can choose to have both segments equal in size, or one can be bigger than the other; it is entirely dependent on your preference. The cost of a small lean-to conservatory roof replacement will be between £2,355 and £2,705, but in factoring in the Victorian element, you can expect to pay a little more, with prices starting at around £4000.

How Much Does A Conservatory Solid Roof Replacement Cost?

While conservatories are traditionally built with transparent roofs to allow sunlight in, many people also opt for a solid, opaque roof, known as a Guardian tiled roof. This is a good option if you would like your conservatory to be especially well insulated, durable and feel like part of the rest of the house, as from the inside, it will be indistinguishable from the main house. However, these advantages do come with an added cost when compared to glass or polycarbonate roofs since more materials are required to make a solid, insulated tiled roof. According to Checkatrade, you can expect to pay between £16,000 and £30,000 to replace your existing 4m x 4m conservatory roof with a tiled Guardian one. It is entirely up to you to decide whether the added durability, insulation and cohesiveness of this style of roof is worth the extra money.

How Can I Save On My Conservatory Roof Replacement?

Finding the right price for your conservatory roof replacement requires some patience and a lot of research. As mentioned before, you don’t want to pick the cheapest option you see, as the small cost may be reflected in the quality of the roof.

Similarly, if you are thinking about picking the most expensive option because you believe you are guaranteed the best roof and service on the market, you would be mistaken. To get the most cost-effective price for the results that you are hoping for, you should do the following:

Compare at least 3 quotes

Getting one quote is not enough to make an informed decision as to whether you are getting the best price for the job. By using online tools, you can easily find reputable companies that will be able to replace your conservatory roof at an affordable price.

Compare local and national installers

Local and national installers will likely use different products for their roof replacement services, which will impact the price. By comparing both, you can decide which products you would prefer, and you will be able to easily identify which installer quotes a fairer price.

Get quotes in writing

A quote in writing is far more beneficial than a spoken word as you can request a full breakdown of the costs. When retrieving quotes from several companies, it is easy to forget who said what, so a physical written document of costs would prevent any confusion.

Make access to your conservatory easy

It is not uncommon for installation companies to quote a higher price if your conservatory is difficult to get to. So, for the lowest price possible, make sure the route to your conservatory is clutter-free.
