Lean-to Conservatory Roof Replacement Cost
How Much Does a Lean-to Conservatory Roof Replacement Cost?
In the current market, online prices for Lean-to conservatory roof replacement cost are averaging anything from £2,500 to £5,500 for a 3×3 conservatory, depending on the material you choose to fit.
In general, conservatory owners go for one of three options, which are:
- Tiles or slates
- Double glazed
- Poly-carbonate sheets
Tiled lean to conservatory roofs are probably the costliest with costs ranging from £250 right up to £900 per square metre. That means a solid tiled 3×3 conservatory roof could cost as much as £8,100 or as low as £2,250.
Double glazed lean to conservatory roofs on average cost less than tile versions. A decent quality glass roof for a 3×3.5 lean-to can cost around £2,500 – £3,500.
Poly-carbonate conservatory roofs are the cheapest option. However, be careful not to use sheets that are too thin. 35mm twin or triple wall panels are best for this job. You could expect to see polycarbonate lean to conservatory roof prices in the range of £1,900 to £2,500 for a 3×3 conservatory.
As you can see, there is quite a bit of variation in costs. Taking some time to think about the type of roof you want to put on your lean-to conservatory is going to be time well spent – especially if you are going to be replacing your old conservatory roof.
In this article, we will be looking at the advantages, disadvantage, features and costs involved of each type of lean to conservatory roof in turn.

Tiled lean to conservatory roof replacement costs and options.
A lot of times we get asked “Can I put a solid roof on my conservatory?” and “How much does it cost to put a solid roof on a conservatory?” and the answer to the first question is a simple “yes”, but the answer to the second question is not quite so clear cut.
There are no real restrictions about putting a tiled roof on a conservatory, other than you need to be aware of any planning permission & building regulations for replacement conservatory roofs that you could be subject to (more on that later in the article – so read on).
How much does it cost to put a solid roof on a conservatory? Is more complex to answer because there are quite a lot of options when it comes to tiled lean-to conservatory roofs, with tiles being made in a wide variety of materials and designs.
The different type of tile you choose will not only have a different price per square metre for the tile itself, there are also structural considerations that may come along with certain types of tiles.
As an example, you may already have a polycarbonate roof and are changing to a tiled roof. Poly-carbonate is very light, however, certain tiles can be very heavy.
If you do a check online, you may see that the weight for concrete or cement tiles can run up to as much as 45kg per square metre for a Marley Ludlow Major 420mm x 330mm tile.
Heavy tiles need stronger support, and this could lead to extra expenses due to having to strengthen the frame of your existing conservatory. Bear this in mind.
Slates are somewhat lighter and more recent entries into the market include lightweight conservatory roof tiling systems such as Tapco, Metrotile & Ultraframe at around 12kg per square meter. These tiles can be made from limestone and polypropylene.
Have your conservatory properly surveyed before adding a new heaver roof.
How much does a tiled lean-to conservatory roof cost?
Based on a price band of from £250 up to £900 for tiled conservatory roof prices per square metre.
- 3000mm x 3000mm from £2250 to £8,100
- 3000mm x 3500mm from £2,625 to £9,450
- 4000 x 4000 from £4,000 to £14,400
We would say that you should keep a budget set aside of at least £4,000 to £6,000 for the average tiled conservatory roof replacement.
Tapco lightweight tiles need about 20 per square metre, so for a 3×3 lean to conservatory you would need about 200 tiles – you can buy these tiles for about £490 supply only.
You would then need to add labour and materials for the roof frame.
Double Glazed Lean to conservatory roof prices and options.
Once again, if you are moving from a polycarbonate roof to a double glazed roof, you will need to consider the impact of additional weight loading. Double glazed units are far heavier that polycarbonate sheets.
Double glazed panels come in different configurations. These are usually referring to the width of the gap between the inner and outer panes, usually from 14mm to 28mm.
Having a lot of clear glass in the conservatory roof can often mean glare from the sun leading to heat build-up. You can combat this by using the most energy efficient units that you can afford, using low emissivity coatings on the glass and installing roof blinds.
A useful option is to have self-cleaning glass – no need to stress out about getting on top of the room to clean it.

Poly-carbonate Lean to conservatory roof replacement costs and options.
A lean-to roof using polycarbonate panels is probably the cheapest conservatory roof in the market.
Having said that, a lot of conservatory owners opt to change to either glass or tile if & when the roof needs to be fixed or replaced.
Poly-carbonate is not the most energy efficient, quiet or visually appealing of roofing materials after some years in place.
It’s often the case that homeowners have polycarbonate conservatory roofs fitted when they buy a new conservatory – it’s seems to be almost the “default” position for installers to fit polycarbonate roofing.
If you are just doing a like-for-like roof replacement, then we would recommend that you look to use the best quality panels that fit within your budget. At least use a twin or triple walled product, that is no less than 16mm thick – however you can go up to 35mm
Having coloured panels will help with managing overhead glare. Bronze or Opal panels are better than clear for this.

Get Free QuotesPlanning permission & building regulations for conservatory roofs.
If you are going to change from a clear to a solid conservatory roof design, then apart from considering the impact of the added weight and loss of natural light (and the costs!), you should also consider local planning permission & building regulations requirements.
If, when you built your existing conservatory you required planning permission, then you need to consult with the local planning department before starting work on the new one. This is because you may need permission and building regulation approval to switch from clear to solid roofing.
If you are going for a tiled roof, local building control (LBC) will require ventilation in the roof such as roof vents, some form of window (Velux) or window trickle vents.
You may find this article “How Big Can A Conservatory Be Without Planning Permission?” or this link useful: Find your local building control team(LABC): https://www.planningportal.co.uk/findyourlabc
