    How Much Does Replacing a Conservatory Roof Cost?

    A professionally installed conservatory will last for decades and will be relatively trouble-free, however, the roofs tend to be the weakest link! If you spot any signs of leaking or water damage in your conservatory, you need to replace the roof as soon as possible to prevent any further damage.

    Leaking roofs are likely caused by damage that has been building gradually over the years due to slipping or warping panels, loose cappings, leaking vents or simply sealant problems around the panels.

    Sometimes a temporary repair can be made to solve the immediate problems, but the only long-term course of action is to either replace the roof or get a new conservatory! But even if the roof is not leaking, if you have a cheap conservatory polycarbonate roof, this can lead to condensation problems over time which in turn can cause mould which is harmful to the lungs, so this may be another reason to consider getting yourself a new conservatory roof.

    Getting a new roof is obviously a lot cheaper than getting a whole new conservatory, but it is still far from cheap! There a number of factors that can affect the price you pay, the two biggest ones being the size of your conservatory and the type of roof material you want.

    Glass roofs are typically more expensive than polycarbonate roofs, but are more energy efficient and let lighter in. As an example, for a small lean-to conservatory, the price to have a replacement polycarbonate conservatory roof fitted is on average around £1900-£2600, whereas a glass roof on the same sized conservatory would cost on average around £2000-£2800.

    Conservatory Roof Prices

    The table below lays out the various costs for different bifold door materials and sizes:

    Roof Type Roof Size Price
    Lean-To Conservatory + Glass Roof Small (up to 8ft x 10ft) £2000-£2800
    Lean-To Conservatory + Glass Roof Medium (up to 10ft x 10ft) £2300-£3000
    Lean-To Conservatory + Glass Roof Large (up to 10ft x 12ft) £2500-£3500
    Lean-To Conservatory + Poly-Carbonate Roof Small (up to 8ft x 10ft) £1900-£2600
    Lean-To Conservatory + Poly-Carbonate Roof Medium (up to 10ft x 10ft) £2200-£3000
    Lean-To Conservatory + Poly-Carbonate Roof Large (up to 10ft x 12ft) £2300-£3200
    Victorian Conservatory + Glass Roof Small (up to 10ft x 10ft) £3000-£4200
    Victorian Conservatory + Glass Roof Medium (up to 13ft x 13ft) £4500-£5800

    Labour Costs and Timescales

    Fitting a new roof on a conservatory requires a minimum of two people to complete the job. With this in mind, the labour costs for fitting a new roof on your conservatory usually fall on average between £300-£500 per day.

    To complete the job of replacing the roof on your conservatory, it will usually take between 1-3 days. The length of time depends on how many people are working on the job, the type of roof that you’re having installed, and the size of your conservatory.

    The roof replacement on a small lean-to conservatory can usually be completed within a day, whereas a replacement on a large Victorian conservatory can take up to three days or sometimes even longer to complete.

    Supply Costs Only

    If you are looking to replace your conservatory roof yourself, or if you wish to buy the supplies and conservatory roof panels in advance before looking into hiring labour to carry out the job, you may be interested in the costs of materials alone.

    The cost for a glass roof on a lean-to conservatory is usually around £2000-£3500 depending on the size of your conservatory. You can expect to pay more for materials if your conservatory is on the larger size than you would for a small conservatory roof. If you were looking to purchase a poly-carbonate roof for a lean-to conservatory, this would cost around £1900-£3200 depending on the size of the conservatory.

    If your conservatory is a traditional conservatory such as a Victorian conservatory, you will pay around £3000-£8500 for the materials of a glass roof and around £3000-£8500 for a poly-carbonate roof on this style of conservatory. Again, these prices range from small conservatories to large ones and you can expect to pay closer to the higher price for larger conservatories and closer to the lower price for smaller conservatories.

    Additional Costs

    There are a few additional costs that you may want to think about when having your conservatory roof replaced. Below are some of those additional costs that you may need to be aware of when having this type of job done.

    Garden Waste Removal Cost

    Depending on the amount of waste that you have and the amount of time it takes to be removed, garden waste removal should cost on average between £100-£200.

    Skip Hire Cost

    Hiring a skip to get rid of the old roof waste and any other waste materials will cost around £120-£300.

    Outdoor Lighting Cost

    Outdoor lighting can come in a number of different styles to suit your personal taste and the average cost range from £10-£100.

    Conservatory Seating Cost

    Conservatory seating comes in a range of different styles to suit your taste and price can range on average between £50-£800.

    Laying Garden Turf Cost

    The cost of laying garden turf averages out at around £12-£20 per square metre.

    Maintenance Gardener Cost

    The cost to have your garden maintained by a gardener is around £20-£40 per hour.

    Timber Decking Cost

    The cost of timber decking ranges depending on the style that you choose, however, this usually costs around £50-£100 per square metre.

    Conservatory Roof Insulation Cost

    Conservatory roof insulation cost is usually around £30-£40 per square metre.

    Cost Factors of Replacing a Conservatory Roof

    There are a number of factors that can affect the cost of having your conservatory roof replaced. Below is a list of the main things that can affect your conservatory roof replacement cost.

    Size of Conservatory

    The size of your conservatory can greatly affect the cost that you will pay for your conservatory replacement. A small lean-to conservatory roof can cost as little as £2000 to replace whereas a large Victorian conservatory roof replacement can cost £8500+.

    The larger your roof is, the more it is going to cost to replace as you will need more materials to cover the entire roof and the job will also take longer so you will end up paying more in labour also.

    Material of Roof

    The material of the roof can make a difference to the amount you can expect to pay for your conservatory roof replacement. As an example, for a small lean-to conservatory, the price to have a polycarbonate roof fitted is on average around £1900-£2600, whereas a glass roof on the same sized conservatory would cost on average around £2000-£2800.

    Location of Property

    The location of your property can also make a difference to the overall cots that you pay for your conservatory roof replacement. Those who live in London can expect to pay anywhere from £30-£100 more per day for labour than those in the North area of the UK.

    What's Involved in Replacing a Conservatory Roof?

    This guide is based on replacing a traditional Victorian style of conservatory roof. This is a big job and should be completed with care to avoid leaks or breakages. Be sure to fully remove your current roof before undergoing the steps below.

    replacingconservatoryroofcosts2
    1. Fit the first section of the ring beam into the correct positioning. Be sure that it’s in the right location before securing. Remember to fit the external trim before positioning the ring beam.
    2. Join the remaining sections of ring beam together using the pressed and flat steel cleats.
    3. From the inside of the windows, fit the ring beams to the window frames. Do this with self-tapping screws at a maximum of 600mm between each fixing.
    4. Hook into position on the ring beam variable support and the ring beam. Slide the appropriate number of studs and single studs along the ring beam variable support. The studs need to be fitted to each of the individual ring beam variable support as they are fitted.
    5. At floor level, ensure that the nylon thread bar has been fitted to the spider bracket and that the ridge variable support and the ridge glazing trim has been positioned within the ridge. Slide the appropriate number of double studs along the ridge variable support for rafter and single studs for gable rafter.
    6. Raise this assembled ridge up to its correct positioning and temporarily support it there. Loosely fit the gable rafters and wall rafter gutter to the ridge and ring beam.
    7. Fix the hips to the spider bar moulding on the spider bar and fix the hips on to the ring beam using single studs. Align the centre of the spider rafters stud hole with the centre line of the hips. Once these have been aligned, tighten up the grub screws.
    8. Fix the gable rafters to the wall with the appropriate fixings. Use a minimum of 3 places per rafter.
    9. Cut to length and fit the eaves beam seal into the ring beam variable support. Be sure not to remove any protective tape just yet.
    10. Complete the lead flashing. The flashing should finish inside the wall rafter gutter. Be sure not to flash around the ridge just yet.
    11. Fit an end cap and a glazing stop to each of the glazing bars with screws.
    12. Fit the glazing end trim to the glazing. If you are fitting polycarbonate roofing, peel back the protective film to enable fitting of the end trim. Seal the end trim with a suitable silicone sealant.
    13. The glazing should be installed in order starting with the ones sat on a hip.
    14. The correct way to glaze involves sliding the glazing panel on the hips or rafters and sliding into the ridge glazing trim if necessary. Remove the protective tape from the eaves beam seal and pull back the glazing sheet to the glazing stop. Then, seat it onto the seal. Pull back the tape film by 1-2 inches and fold to the inside of the conservatory. Position the glazing and ensure that it is sealed down on the glazing stops. Peel away the tape film and pat the glazing down from the outside.
    15. Once you have the glazing in the right position, the hip top caps can be fitted. Make sure they butt unto the ridge end sealing assembly.
    16. Fit the ridge end sealing assembly.
    17. Before you fit the ridge top cap, apply a continuous bead of gap filler to all of the areas of the ridge flashing trim where the top cap will be placed. Then, slide the flashing trim onto the ridge top cap.
    18. Apply a continuous bead of the gap filler also into the opposite end of the ridge top cap where the ridge end top cap will be placed. Slide the ridge end top cap onto the ridge top cap and fix it in place using poly top screws.
    19. Fit the assembled ridge top cap onto the ridge. Before you position it, apply a silicone sealant to the areas of the ridge flashing trim that butt up to the wall. Then you can secure the top cap into position.
    20. Complete all of the lead flashing around the ridge flashing trim.
    21. The crestings and finial can now be slid on to the ridge channel.

    Can I Replace a Conservatory Roof Myself?

    Although replacing a conservatory roof could be completed by a couple of DIY enthusiasts, it is highly recommended that you hire a professional company or labourer to complete the work for you.

    replacingconservatoryroofcosts3

    If the work is not carried out correctly and effectively, the conservatory roof could be prone to damage or leaks.

    A leaking conservatory roof could lead to much worse problems down the line and could result in some hefty costs.

    Choosing a Conservatory Roof

    The two main types of conservatory roof are glass roofs and polycarbonate roofs. Below is a little bit of information on each of these types of roof.

    Glass Conservatory Roof Cost

    A glass conservatory roof is perfect for letting a lot of light into the room. If you really want to brighten up your conservatory space, then a glass roof is definitely the way to go.

    replacingconservatoryroofcosts4

    A glass conservatory roof is a little bit more expensive than a polycarbonate roof. You can expect to pay around £200-£1000 more for a glass conservatory roof depending on the size and style of your conservatory.

    Pros:

    ✔ Let’s in a lot of light

    ✔ Strong

    ✔ Durable

    ✔ Easy to clean

    ✔ Great aesthetic

    Cons:

    ✖ More expensive than other options

    ✖ Can make the room very hot in summer

    ✖ Can make the room very cold in winter

    Polycarbonate Conservatory Roof Cost

    A polycarbonate conservatory roof is a great budget-friendly option for those who want to replace their existing roof.

    replacingconservatoryroofcosts5

    It is strong and durable and can save you around £200-£1000 in installation and materials cost when compared to a glass conservatory roof.

    Pros:

    ✔ Budget-friendly option

    ✔ Strong

    ✔ Durable

    Cons:

    ✖ Not as aesthetically pleasing as glass

    ✖ Can develop grime over years if not well maintained

    Tiled Conservatory Roof Cost

    Some people choose to completely remove their conservatory roof and replace it with a tiled roof. This is a more modern approach and removes the aesthetic of the conservatory.

    replacingconservatoryroofcosts6

    Since a conservatory was originally designed as a room to grow plants, the tiled look takes away the tradition of a conservatory and makes it more like just an extension on the home.

    Pros:

    ✔ Strong

    ✔ Durable

    ✔ Blends in with the rest of the house

    ✔ Doesn’t get too overheated or too cold during summer and winter months

    Cons:

    ✖ Not traditional

    ✖ Doesn’t look like a conservatory

    ✖ Pricey

    Benefits of Replacing a Conservatory Roof

    There are a number of benefits to replacing your conservatory roof. Below is a list of the main benefits that a replacement conservatory roof may bring to you and your home.

    Prevent Leaks and Damage

    A major benefit of replacing your conservatory roof is that your new roof will be free from any leaks or damage. If you are replacing your roof for the purpose of fixing a leak, a major benefit is that your new roof will prevent those leaks from happening.

    replacingconservatoryroofcosts7

    More Likely to Last

    A brand-new roof will be more likely to last a long time than your older roof. Over time, your roof can develop damage from things such as the weather. Modern roofs are built to last and so having a new roof put on your conservatory will ensure that your conservatory lasts for a very long time without issues such as damage or leaks.

    Aesthetically Pleasing

    Anything that is brand new looks great and a new roof on your conservatory is no exception to this. There are many great styles of roof available and you can even get tinted or coloured roofs that will make your home look great. A new modern-looking roof can completely transform the look of your conservatory.

    Building Regulations for Replacing a Conservatory Roof

    Most of the time you will not need any buildings regulation approval to replace your conservatory roof. As long as there is ‘thermal separation’ between the conservatory and the rest of your home, you can replace your conservatory roof without any restrictions.

    This means that you need a door separating the conservatory from the rest of the house. The majority of conservatories already have this in place as a conservatory is known for getting quite hot in the summer months and cold in the winter months.

    It is also important to ensure that your new conservatory roof is strong enough to withstand weather conditions and is strong enough to carry snow if the situation arises that there is a heavy snowfall. Most modern conservatory roof materials are fully built ready for this and will come with the appropriate building regulation approval already.

    replacingconservatoryroofcosts9

    The only time that buildings regulations may come into play is if you are replacing your conservatory roof with a solid roof such as having a tiled roof put on rather than a glass or polycarbonate roof.

    In this case, your conservatory may be seen as being an extension rather than a conservatory. The company that carries out the work on your new roof will be able to provide you with the appropriate guidance regarding your particular conservatory and whether any building regulations rules may need to be approved for your specific roof replacement.

    Planning Permission for Replacing a Conservatory Roof

    Planning permission is concerned with any changes to your home that may affect your neighbours or the wider environment. Since your conservatory is already there, and you’re simply replacing the already existing roof, you do not need to worry about planning permission to change your roof.

    It doesn’t matter what the type of roof is that you are replacing or that you are having put on your conservatory, you don’t need to worry about planning permission to have your conservatory roof replaced.

    Removing a Conservatory Roof Cost

    If you are looking at replacing your conservatory roof, you may be interested in removing the original roof to save some time or costs. Most companies that offer conservatory roof replacements will remove and dispose of the old roof as part of the job. However, you may want to remove the roof yourself if you would prefer to do so.

    This can be done as a DIY project, but great care should be taken as removing a roof can be dangerous. You need to be aware of objects that may drop as you’re removing the roof, and so appropriate safety wear including a hard hat and safety glasses should be worn when carrying out this job.

    replacingconservatoryroofcosts8

    There is likely to be a lot of waste generated when removing the roof. In this case, it is recommended that you hire a skip to dispose of the waste materials.

    A skip hire will cost somewhere between £100-£300 on average for this type of job and the size of skip that you hire will depend on the size of your conservatory roof and the amount of waste that you anticipate the job is going to create.

    Hiring a Conservatory Roof Replacer Checklist

    There are a number of things that you should consider when hiring a roof replacer. Below is a list of things that you may want to think about when choosing someone to carry out the work of replacing your conservatory roof.

    • How much experience does the person/company have in removing and replacing a conservatory roof?
    • Does the person/company offer any guarantees with their work?
