How Much Does a New Conservatory Roof Cost?

How Much Does a Conservatory Roof Cost

Prices start from around £2,500 for an average-sized conservatory if you want to replace your conservatory roof with polycarbonate panels.

This is the cheapest material you can use, however with the low price come drawbacks. The life expectancy of a polycarbonate conservatory roof replacement is relatively short compared to other options. Polycarbonate conservatory roofs also do little to tackle the issues of heat in summer and cold in winter that plague many conservatory owners.

Our customers often ask us how much one of our replacement conservatory roofs will cost before we’ve been able to visit and measure up. They often ask for a ballpark figure or a guide price, based on the footprint of the conservatory or the number of panels in the roof.

There are so many different factors that affect the price. Read on and we will try to give you an idea about replacement conservatory roof prices…

Replacement Conservatory Roof Prices

Since planning regulations were changed in 2010, lots of different roofing options for conservatories have become available. Most of our customers get quotes for some or all of these, in fact, we encourage it, as all have their merits. Your decision will come down to what you want to achieve and the quality of installation or service you would like.

Listed below are the various options and rough prices in relation to a GreenSpace replacement conservatory roof.

Polycarbonate Replacement Conservatory Roof Cost

The cheapest option (for a reason)

By far the cheapest way to put a roof on your conservatory. The lightweight plastic provides little or no insulation, so your conservatory will still be too hot in summer, cold in winter, and noisy in bad weather. Naturally, a GreenSpace roof is usually more expensive, and eight times more efficient at insulating.

Double Glazing Cost

More expensive than polycarbonate, usually cheaper than a Green Space roof.

More expensive than polycarbonate, much stronger and heavier, but won’t solve the overheating in summer and won’t keep the heat in during winter.

Tinted Glass / Self-Cleaning Glass Cost

More expensive than double glazing. Usually cheaper than a Green Space roof (though we have seen some quotes have come in more expensive).

While this option reduces glare in your conservatory, we’ve had varying reports from customers as to the effect it has on temperatures and actually replaced quite a large number of these roofs that haven’t been in situ that long at all.

Internal cladding Cost

Probably the cheapest non-transparent option.

There are numerous companies now offering this option. It’s simple. A thin layer of insulation is applied to the underside of your existing roof, then PVC cladding is applied under that. It’s the cheapest way to make your roof non-transparent and insulated. You need to consider longevity, as this fixes to the underside of a roof that is often at the end of its life and it does nothing to address the exterior.

Tiled roof conversion Cost

Similar price to a Green Space Roof.

Lightweight tiles are applied to the outside of your roof. Sometimes the frame is replaced or reinforced to take the extra weight. Insulation is applied underneath and a plasterboard ceiling is put up. This is then plastered and decorated. It’s a big job and often takes 3 or 4 days. You also need to be certain that the conservatory will take all of that extra weight and check guarantees offered.

This option offers a good level of noise and heat insulation and (depending on the quality of tradesman who installs it) a nice-looking finish.

We have found that these roofs are often a similar price to a Green Space roof. Sometimes they are slightly more expensive, other times slightly cheaper. There are many variables that affect both prices.

It’s safe to say that the tiled roof conversion and Green Space roof are the most comprehensive ways to transform your conservatory into a room you can use all year round. They come in at a similar price point, so your decision (once you’ve gathered your quotes) will come down to three main factors:

  1. The look of the roof when installed.
  2. The amount of disruption you are willing to put up with during installation.
  3. The trust you have in the company to deliver what they have promised.

Conservatory insulation costs

As you might expect a Green Space roof isn’t the cheapest option but we strongly believe it is the best option. If you compare conservatory insulation costs to the amount you could save on heating your conservatory during the winter and the space you can reclaim by having a working conservatory we believe the initial outlay is a no brainer.
