Does Insulating A Conservatory Roof Add Value

Can I increase the value of my home by insulating my conservatory's roof? This article hopes to answer that question and offer additional useful information about conservatory insulation.

Why Insulate a Conservatory?

Insulation is one of the most important parts of any home. Specific areas of your property may have already been insulated, for example, the walls or the loft. This is done in order to maintain a comfortable living environment throughout the home. As the conservatory will be used as an additional living space, the room is no different.

The usual method of insulating a conservatory is by installing the insulation within the roof. This will make the whole conservatory area usable all year round, or at least usable for more months of the year rather than just summer. That being said, no matter how much insulation and draught-proofing goes into a conservatory structure, it is still made almost entirely of glass.

This means that the room will always be warmer in the summer months and cooler in the winter months, more than anywhere else in your home. You should also keep in mind that if the link between your home and your conservatory is uninsulated when it will have a large impact on the overall efficiency of the room's ability to retain heat. Insulating the link can simply mean using an insulated curtain or some form of a thermal break. This will keep your house staying warm efficiently.


How much Value To Your Home will a conservatory add?

A high-quality and inviting conservatory is almost always everyone's favourite spot in the home.

Conservatories have gorgeous levels of natural light, as well as views of your garden, and they offer a space where you can escape from the commotion of the average family home.

A conservatory is your own little oasis of calm. You can't put a price on the feeling of relaxation you will feel after a long day at work, coming into your conservatory and putting your feet up.

However, you will find that there are genuine substantial benefits of upgrading to a well-insulated conservatory. These are not possible with any other type of home improvement.

The benefits include: 

 Money will be saved on energy bills for both air conditioning and heating

Money can be saved on repairs to polycarbonate conservatory roofs and damage-prone glass

There will be no need to pay for the additional insulation panels

Instead of constructing a whole new room, a conservatory conversion is essentially a cheaper home extension

The property's market value will experience an estimated increase of between 5-12%

The above are just some of the financial benefits and potential savings you can make by having a conservatory roof replacement.

Replacement conservatory roofs

There are many factors that can affect the price of a property, both nationally and locally. Some properties will hit a ceiling where carrying out even more work on the property will not lead to an equivalent rise in value.

In general, though, a replacement conservatory roof will be an upgrade that will add real tangible value to a property.

There are also annual energy bill savings to be made. It is estimated that the average homeowner will save £200 per year if they have a replacement conservatory roof installed. This amount is only a small sum in comparison to the large increase in property value.

Anyone that looks around a house featuring a conservatory with a glass or polycarbonate roof will know that it is a flawed space and detrimental to the overall property.

It could be that the potential buyer attaches zero value to the room, or they could even be mentally trying to figure out how much it would cost to have the roof removed when they are considering their offer on the property. With a home extension, you are gaining the perk of having a brand new usable living space. A conservatory does not always have this appeal.

A replacement conservatory roof will help to bridge the gap between the price of a home with a conservatory and the price of a home with the same extra square footage but with an extension rather than a conservatory. A replacement conservatory roof will make the space as usable as an extension.

Replacement conservatory roofs are available in a range of different styles and colours to keep your conservatory aesthetically appealing. 


 Insulated ceilings will prevent overheating in the summer months

Will assist in retaining much-needed heat in winter

You will no longer need to contend with the irritating glare from the sun

Insulated ceilings can be installed on almost all types of conservatory roofs

An insulated ceiling will not minimise your ceiling size

No change to your interior space whatsoever

How to Insulate a Conservatory Roof

Insulating a roof on a house, if done correctly, will achieve a U-value of no more than 0.16W/m2K. In comparison, on average, you can expect a polycarbonate conservatory roof to have a U-value of around 1.6W/m2K to 2.4W/m2K. This is at least ten times worse than the average house roof.

The best and only efficient way to achieve a better U-value rating when it comes to conservatory roofs is by replacing the polycarbonate roof with a slate or tile. These will usually be plastic slates or tiles in order to save on weight. The same level of insulation that is used on the rest of the house will be installed in this new roof. Commonly this will cost around £10,000 or over.

Insulating a conservatory roof is a highly popular area of the construction industry. There are more companies offering to install solid roofs on conservatories than there have ever been. But, the retrofitting of a solid roof assumes that the frame of a conservatory is strong enough to carry the weight of a new roof. This is something that must be checked before the work is undertaken.

As an alternative, there is a large number of companies that are now offering to install lightweight internal roof insulations on conservatories. These roofs are much cheaper than solid roofs, around less than half the prices, but it will only reduce the U-value to 0.8W/m2K.

Obviously, this is not quite matching the house's U-value, but it will go a long way to making the conservatory suitable all year round.

How Much Does it Cost to Insulate a Conservatory Roof?

Replacing your conservatory's polycarbonate roof with an insulated solid roof will cost somewhere in the region of around £10,000 or even more. It is important to remember that if the construction of a solid roof is done at the same time as the conservatory is erected, then the cost will most likely be half.

This is the best way to achieve a year-round usable space. A lightweight internal roof solution will not achieve the same U-value as a solid roof, but will cost will be at least half or lower. 

How Much Heat Is Saved by Insulating a Conservatory Roof?

An entirely glazed conservatory of around 4 metres by 5 metres will need around 3 kilowatts of heating in the winter months.

  That exact same room with a replacement lightweight insulated roof will need around 2.7 kilowatts. So you should expect a saving of roughly around 10%.

The same room but with a replacement roof will require around 2.5 kilowatts. This means you will be receiving a 16% saving simply just through installing insulation.

The maximum that can be saved by using insulation within a conservatory roof is around 600 kilowatt-hours per year, with a value of just under £40. The benefit that you do gain from insulating a conservatory is smoothing the harsher aspects of the weather. The storms, snow, and hail. The insulation will make the room far more comfortable and usable all year round, even in the colder seasons.
