How long do conservatory roofs last?

Last Updated: 28 September 2023

The lifespan of a conservatory roof is dependent on a range of variables. The materials used to build a conservatory have the most significant influence, but the positioning, climate, and craftsmanship also have a big say. We have looked at these various factors to help you learn more about conservatory lifespan.

Polycarbonate conservatory roofs

You can expect polycarbonate roofs to last for about 20 years. However, if you have a polycarbonate roof which is between 10-20 years old, it is highly likely that it fails to maintain a comfortable temperature in the conservatory. So, we recommend replacing it sooner rather than later.

Glass conservatory roofs

Tiled conservatory roofs

While some are made to last, even the best-built conservatories need to be repaired or replaced eventually.

How to know that your roof needs replacing

If your conservatory roof is older than the standard lifespan, you should consider replacing it. This is true even if it still manages to keep the weather out because its thermal performance will not be able to compete with the conservatory roofing solutions available today.

There could also be underlying damage or wear and tear of crucial aspects of the roof. Some other things to look out for are:

  • Damaged tiles
  • Moss and algae growth
  • Leaking, draughts or cold spots

What factors cause a conservatory to deteriorate quicker?

Conservatories that are continually exposed to strong winds, heavy rain and other extreme weather conditions will deteriorate more quickly. Continuous UV exposure also hastens the rate of deterioration, an issue that is more prevalent with south-facing conservatories.

Failing to perform periodic maintenance is another big factor, so we would always suggest repairing and replacing old/broken components when necessary.
