Conservatory Roof Replacement Cost by Material

Let’s take a deeper look at the three main roofing materials and how they affect conservatory roof replacement costs.

Polycarbonate Conservatory Replacement Roof Costs

Once again, polycarbonate is more affordable than the other two conservatory roofing materials. However, it also has more weaknesses. Mainly, it has relatively poorer heat insulation and noise reduction.

You can find ways to improve these two attributes, which will involve more expenses, thereby increasing conservatory roof replacement costs. Here is a table of polycarbonate replacement roof costs for lean-to, Edwardian and Victorian conservatories of 9 and 25 square metres.  

Roofing material	Conservatory type	Conservatory size	Conservatory replacement roof cost
Polycarbonate	Lean-to	3m x 3m	£2,200-£2,600
Polycarbonate	Lean-to	5m x 5m	£3,000-£3,600
Polycarbonate	Edwardian	3m x 3m	£3,850-£4,400
Polycarbonate	Edwardian	5m x 5m	£5,200-£5,700
Polycarbonate	Victorian	3m x 3m	£3,400-£4,200
Polycarbonate	Victorian	5m x 5m	£4,500-£5,500

Glass Conservatory Replacement Roof Costs

Glass is a more expensive conservatory roofing material compared to polycarbonate. However, it also has better thermal efficiency and noise reduction. In fact, glass is better in so many other ways. For example, natural light supply is higher and there are high-tech options like self-cleaning glass.

These features are why glass is the most common conservatory roofing material. Here is a table showing glass replacement roof costs for lean-to, Edwardian and Victorian conservatories of 9 and 25 square metres.

Roofing material	Conservatory type	Conservatory size	Conservatory replacement roof cost
Glass	Lean-to	3m x 3m	£2,500-£3,200
Glass	Lean-to	5m x 5m	£4,000-£4,600
Glass	Edwardian	3m x 3m	£4,700-£5,500
Glass	Edwardian	5m x 5m	£5,200-£6,000
Glass	Victorian	3m x 3m	£4,600-£5,200
Glass	Victorian	5m x 5m	£5,000-£5,700

Tile Conservatory Replacement Roof Costs

Conservatory roof replacement costs are highest when using tiles. However, there are many benefits, which is why many people are now choosing this material. Such benefits include good thermal efficiency, privacy, durability, and noise reduction. Tile also has a unique aesthetics and is low maintenance.

However, high conservatory roof replacement cost is not the only reason to think twice about roofing tiles. As a solid material that doesn’t allow light to pass through, tile roofing takes away some of that unique conservatory aesthetic. Condensation is also an issue.  

Finally, there could be complications when using a heavy material like tile to roof a conservatory. Tile is just much heavier than glass and polycarbonate. The issue is even more significant if the tile roof replaces a glass or polycarbonate roof. Therefore, the conservatory must meet building regulations.

Finally, upon installing a tile replacement roof, the conservatory no longer qualifies as a temporary structure. It becomes a permanent one that needs planning permission. The cost of passing planning permission and building regulations will further increase conservatory roof replacement costs.

Here is a table showing tile replacement roof costs for lean-to, Edwardian and Victorian conservatories of 9 and 25 square metres.

Roofing material	Conservatory type	Conservatory size	Conservatory replacement roof cost
Roof tiles	Lean-to	3m x 3m	£5,000-£6,200
Roof tiles	Lean-to	5m x 5m	£7,000-£8,200
Roof tiles	Edwardian	3m x 3m	£8,000-£9,500
Roof tiles	Edwardian	5m x 5m	£10,000-£11,000
Roof tiles	Victorian	3m x 3m	£7,500-£8,200
G Roof tiles	Victorian	5m x 5m	£9,500-£9,800

Factors Affecting the Cost of a Conservatory Roof Replacement

Here are the four factors that determine conservatory roof replacement costs.

Conservatory Roof Size

Size is easily among the top 3 factors that affect conservatory roof replacement costs. The bigger the roof, the more it will cost. Material costs will increase, and so will labour costs. Therefore, it’s only natural for the entire project’s cost to increase.

Conservatory Roof Material

This article has a section dedicated to how the choice of roofing material affects conservatory roof replacement costs. So, there is no need to write an epistle here. Let’s do comparisons instead. Polycarbonate is the cheapest conservatory roofing material. Glass is next in line, while tile is the most expensive.

These price differences aren’t just caused by the individual cost of the materials themselves. In the case of roofing tiles, the higher cost is also due to the complexity of using a heavy material like tile on a glazed building like a conservatory. Either way, your choice of roofing material will affect conservatory roof replacement costs.

Conservatory Style

There is also a dedicated section exploring how conservatory style affects conservatory roof replacement costs. So, let’s forgo another epistle in favour of price comparison. Here is the order of replacement roof costs according to conservatory style.

A lean-to conservatory’s replacement roof is the cheapest. Next are Victorian, Edwardian, Georgian, and finally, lantern and uniquely-shaped conservatories. A lean-to conservatory’s roof replacement costs the least because of design simplicity. Conversely, replacement roofs for uniquely-shaped and lantern conservatories caused the most because of design complexities. Examples of uniquely shaped conservatories are P-shaped and L-shaped ones.  

Your Location

Your location also affects conservatory roof replacement costs. It does this in three ways. Firstly, big cities and southern parts of the UK have higher living standards, so labour costs tend to be higher. Secondly, conservatory installers might want higher rates if they have issues accessing the site.

Finally, installers could also charge more money if they come from afar. All these three reasons allow location to affect conservatory roof replacement costs.

Do I need Planning Permission For A Replacement Conservatory Roof?

How long does a conservatory roof replacement take?

On average, for the small, simple reroofing of a lean-to conservatory, it could take just a day, but it could take about 3-5 days for a more complex reroofing. The extra days are due to the extra work that goes into the structural work, especially if you are replacing it with a solid roof.

If you are to consider the amount of time it takes before the roof arrives at your property, you should add an extra 3-5 weeks.

Is it possible to fix a leaking conservatory roof myself?
