    Replacement Conservatory Roof Cost

    How Much Would a Replacement Conservatory Roof Cost?

    If you are trying to find out the replacement conservatory roof cost for your conservatory, you have come to the right place. You might need a replacement conservatory roof because your old one has become damaged. It could also be because it is not performing as well as it used to.

    replacement conservatory roof cost

    Whatever the reason, you have decided to replace it and now want to know what it will cost you.

    The bad news is, there is no simple answer to this question. You need to consider multiple factors, all of which affect the replacement roof cost.

    However, the good news is that it’s quite simple to find out the factors. You can analyse them to determine your tentative replacement conservatory roof cost.

    Understanding the different aspects of replacement conservatory roofs also means you will make a better choice. Once you have understood the various aspects of roof replacement, you will be able to assess your needs better. As a result, you will be able to determine the best option for you.


    What Do You Need to Consider For Your Replacement Conservatory Roof Cost?

    A conservatory roof serves a very important function. It is obviously very important in protecting the occupants and the objects in the room from the elements. However, it also helps the conservatory in performing optimally. As a result, the features you want make a difference in your replacement roof cost.

    First, you need to ask yourself what you need from your conservatory roof. What are the stylistic requirements? This will affect the shape and size of your replacement roof. Both the shape and size are factors that will affect the cost.

    Second, do you want a solid roof or a glass roof? A solid or a tiled roof gives you more privacy, security and permanence.

    However, it does not let in as much light. If it’s natural light you want, you should consider a glass roof. If you want limited natural light, you can even choose a polycarbonate roof. This lets in a limited amount of filtered light.

    Conversely, you can illuminate your conservatory with roof lanterns or windows. These are ideal if you want the features of a solid roof but also illumination.

    All these factors will have a bearing on your replacement conservatory roof cost!


    How do these factors affect your roof cost?

    How Does Size Affect Your Replacement Conservatory Roof Cost?

    The size of your conservatory roof is a major factor in determining the replacement cost. Obviously, the larger the roof, the more material the roof requires.

    In addition to the large size of the roofing material, you also have to consider the support it will need. A larger area will need more frames and support. A smaller area, on the other hand, might not need any additional support.

    A larger replacement roof will also take longer to install. As a result, your installation cost will be affected.

    Does the Roof Style Influence the Replacement Conservatory Cost?

    Conservatories come in different styles and materials. As a result, the different styles also have different roof designs. Consequently, the intricacy and complication of the design affects the replacement conservatory roof cost.

    What do we mean?

    Let’s take an lean-to conservatory. This style has a basic single-sloped roof. A 3000mm x 3500mm roof made out of polycarbonate will cost you about £2,345 to £2,865.


    Compare that with an Edwardian roof of size 4000mm x 4000mm. Even though there is a relatively small difference in size, there is a significant difference in price. A replacement roof made out of polycarbonate will cost between £4,480 and £5,120.


    Changing the style of the roof is a cheap and effective way of revamping the look of your conservatory. If you have a basic rectangle shaped conservatory, you can easily give it a new look with a different roof.

    Lean-To Conservatory Roofs

    lean-to aluminium conservatory roof - replacement conservatory roof cost

    A lean-to conservatory is a simple rectangle or square shaped extension with a single-sloped roof. The highest point of the roof sits against the wall of your property. This gives the conservatory the impression of leaning against the house. This is what gives the style its name.

    This style has the least complicated roof design. It is a flat roof with no fancy design features. The structure is held in place with regularly spaced support frames.

    This obviously translates to the lowest replacement conservatory roof cost. Out of all the different roof styles, this one will cost you the least.

    As mentioned earlier, a polycarbonate roof of size 3000mm x 3500mm is about £2,355 to £2,705. A similarly sized glass roof would be about £2,610 to £3,175.

    Victorian Conservatory Roofs

    replacement conservatory roof cost - victorian conservatory

    The Victorian conservatory is characterised by the bay window on one wall. The 3 or 5 faceted window gives the wall a ‘curved’ shape.

    As a result, the roof on this end of the conservatory is broken up into the same number of triangular panels as there are facets. This translates to a higher replacement roof cost than a simpler roof style.

    Just as a basic cost estimate, the replacement conservatory roof cost of a 4000mm x 4000mm polycarbonate Victorian roof would be around £4,345 to £5,005.

    In comparison, a glass roof in the same size would cost you anything between £4,740 and £4,345.

    Edwardian Conservatory Roofs

    The Edwardian conservatory is defined by its beautiful double-hipped roof. You can play around with the angle of the pitched roof to make your conservatory taller and more impactful.

    The spectacular pitched roof is great for elegant style, but also means a higher cost. This is due to the multiple facets and the frame that go into creating the double hipped shape.

    To give you a rough idea, a polycarbonate roof that is 4000mm x 4000mm would cost you around £4,480 to £5,120. Similarly, the glass replacement conservatory roof cost of the same size would be anything from £4,875 to £5,570.

    Gable End Roofs

    gable conservatory - replacement conservatory roof cost

    This style is a spectacularly dramatic conservatory style which is instantly recognisable by its roof. The Gable end roof is made up of two inclined planes. These planes meet at their highest point in the centre to create an inverted V.

    As a result, the front of the roof is a triangle formed in the cross-section.

    This triangle can be embellished with designs. These can be as simple as vertical panels, or as elaborate as a multi-segmented sunburst pattern. The more elaborate the design, the higher the replacement conservatory roof cost.

    This roof can be so varied in design that its cost spans from £2,400 for a small sized roof to £5,800 for a glass roof. In general, you can expect a figure that falls between these two. However, it will depend on the style you want and who you get to install it.

    P-Shaped Roofs

    A P-shaped conservatory is made by combining a rectangle or square shaped conservatory with a Victorian conservatory. The shape would be an L-shape but for the curved bay window, which makes it more of a P shape.

    Since there is no fixed size or proportions in this combination, the size and shape of the roof can vary greatly.

    As a result, there is no way to accurately estimate the replacement conservatory roof cost without knowing the measurements. Suffice to say, the size and the detailing in the design will add to your total cost.

    T-Shaped Roofs

    t-shaped conservatory - replacement conservatory roof cost

    A T-shaped conservatory can be made by combining two rectangular shaped conservatory styles. For example, you can have a large lean-to conservatory against the wall of the property. If you have an Edwardian, Gable end, or even a Victorian style projecting from its centre, you get a T shape.

    As with the P-shaped conservatory, the replacement conservatory roof cost of this style depends on the size and intricacy of the design. Of course, the material used will also affect the price.

    In What Way Do Different Materials Affect the Replacement Conservatory Roof Cost?

    Conservatory roofs are made up to two components. These are the roof itself and the frame that holds it. The frame of the roof can be uPVC, timber, or aluminium. The roof material can be polycarbonate, glass, or solid. Each of these materials affects the replacement conservatory roof cost.

    uPVC Replacement Conservatory Roof Cost

    uPVC frames are extremely durable and easy to care for. They are also the cheapest frame material. The biggest advantage you get with these frames is thermal efficiency. These frames are great for insulation.

    Moreover, they are available in a stunning selection of colours and finishes. uPVC frames are also exceedingly strong and secure.

    In short, they are a cost-effective option that offer great performance.

    Timber Replacement Conservatory Roof Cost

    Timber frames are more about 50% more expensive than uPVC frames. They also require a greater degree of care and upkeep. However, they are long lasting and quite heat efficient.

    The timber frames are also the preferred option for heritage properties as well as houses in conservation area.

    Aluminium Replacement Conservatory Roof Cost

    Aluminium frames for conservatory roofs cost about 30% more than uPVC frames. However, they are slimmer and much more elegant looking. They are immensely robust, and can withstand the ravages of the elements much more effectively.

    Like uPVC, they are easy to care for, but may not be as thermally efficient.

    Polycarbonate Replacement Conservatory Roof Cost

    Polycarbonate is the cheapest replacement roof option. It is light-weight, and does not require much work in the foundation. It is also easy to clean, and great for south or south-west facing conservatories. This is because it is not as clear as glass, and therefore limits the amount of sunlight.

    However, it is not a durable material and may need to be replaced quite frequently. Also, it is not as silent as the glass or tiled alternatives. If the sound of rain on your roof bothers you, this might not be the right material for you.

    Glass Replacement Conservatory Roof Cost

    A glass roof will cost you more than a polycarbonate one. However, you will get better performance and a longer life. Double glazed roofs will give you better heat retention and sound proofing. They will also give you better security.

    However, unless you get tinted glass or roof blinds, you will not have much control over the amount of sunlight you get. As a result, your conservatory might become hot on warm and sunny days.

    Tiled or Solid Replacement Conservatory Roof Cost

    Tiled or solid roofs are the most durable roof options for your conservatory. They are also great for heat efficiency and security.

    However, they cost much more than glass or polycarbonate. They also limit the amount of light you get, which might be a consideration if you wanted a conservatory for the extra sunlight.

    Moreover, if your conservatory foundation was not designed for extra weight, this might not be a very feasible option.

    How do Roof Features Affect Your Replacement Conservatory Roof Cost?

    If you want additional features on your conservatory roof, they will end up adding to the total cost. These features include roof lanterns, which you might want for extra light in case of solid roofs. Roof lanterns may be flat along an incline or pitched.

    Again, the size, material and the number of windows will affect the total replacement conservatory roof cost. Also, there may be other considerations that might affect your choice of design.

    How Can Your Choice of Installer Affect Your Replacement Conservatory Cost?

    Finding a reliable installer can be very important. A trustworthy installer would follow building regulations and industry standards to give you a high quality installation. On the other hand, an unreliable installer might give you a good-looking conservatory roof that starts giving you problems a few months down the line.

    In such a situation, you may not want to go with the cheapest installer. However, you don’t have to choose the one who gives you the highest replacement conservatory roof cost estimate either. Look for local accredited installers, preferably certified by FENSA or CERTASS.

    Get quotes from at least three such installers before making your choice to get the most competitive rate for your roof replacement.
