The Ultimate UK Guide to the Conservatory Roof Cost Calculator
For homeowners across the UK, a conservatory can be a wonderful addition, bridging the gap between home and garden. However, many older conservatories suffer from a common problem: an outdated roof. A classic polycarbonate roof often leaves the room too hot in summer, freezing in winter, and deafeningly loud in the rain. Replacing your conservatory roof is one of the single best investments you can make to transform this space into a year-round, usable room. But what does it cost? Our **Conservatory Roof Cost Calculator** is here to demystify the pricing and provide you with a detailed, realistic estimate for your project.
Why Replace Your Conservatory Roof? The Benefits
Upgrading your roof is more than just an aesthetic choice; it’s a functional one that dramatically improves your home.
- Year-Round Usability: The primary benefit is improved temperature regulation. A modern glass or solid tiled roof provides far superior insulation, keeping the room warm in winter and cool in summer.
- Energy Efficiency: Better insulation means less heat escaping in winter and less need for expensive air conditioning in summer. This translates directly to lower energy bills.
- Noise Reduction: Tired of the rain sounding like a drum solo? A glass or tiled roof offers a massive reduction in noise from rain and weather compared to polycarbonate.
- Increased Property Value: Transforming your conservatory from a seasonal room into a permanent, year-round living space is a significant upgrade that adds tangible value to your home.
- Improved Aesthetics: A new roof can modernise the look of your conservatory, both inside and out, making it feel more like a seamless extension of your home.
The Main Types of Conservatory Roofs: A Cost and Performance Comparison
The biggest factor in your **conservatory roof replacement cost** is the material you choose. Our calculator lets you compare these options directly.
1. Polycarbonate Roof (The Budget Option)
This is the traditional choice. It consists of multi-wall plastic sheets. While it's the cheapest option, it has significant downsides.
- Pros: Lowest cost, lightweight (often doesn't require strengthening the existing frame).
- Cons: Poor thermal insulation, very noisy in rain, can discolour over time, shortest lifespan.
- Estimated Cost: £100 - £200 per m².
2. Glass Roof (The Bright & Modern Option)
A double-glazed glass roof is a huge step up from polycarbonate, offering excellent light transmission and a modern feel. The type of glass is crucial.
- Standard Glass: Offers better insulation and noise reduction than polycarbonate.
- Solar Control Glass: This is a highly recommended upgrade. It has a special coating that reflects a large portion of the sun's heat, keeping the conservatory cooler in summer without sacrificing much light. Our calculator allows you to compare the cost.
- Pros: Excellent natural light, much quieter, modern look, good lifespan.
- Cons: More expensive than polycarbonate, can still get warm without solar control glass.
- Estimated Cost: £250 - £500 per m² (depending on the glass specification).
3. Solid Tiled Roof (The Ultimate Extension Feel)
This option transforms your conservatory into what feels like a proper home extension. It involves building a lightweight tiled roof structure.
- Pros: The very best thermal performance, making the room usable in all weather. Extremely quiet. Aesthetically pleasing, blends with your home.
- Cons: Highest cost, results in a loss of natural light (often mitigated with Velux-style roof windows), may require Building Regulations approval.
- Estimated Cost: £400 - £700+ per m².

- Select Optional Extras: Tick the boxes for any additional work you require, such as internal plastering (common with solid roofs), Velux windows, or new guttering.
- Adjust Cost Assumptions (Advanced):** For a more tailored estimate, you can change the default daily labour rate and skip hire cost to match prices in your local area.
- Analyse Your Results: The calculator instantly provides a total estimated cost range and a detailed breakdown of where that money goes.
Understanding Building Regulations (A UK-Specific Guide)
One of the most important considerations, especially for solid roofs, is Building Regulations. Here’s a simple guide:
- Like-for-Like Replacement: If you are replacing an old polycarbonate or glass roof with a new one of the same type, you generally do **not** need Building Regulations approval.
- Changing to a Solid Roof: If you are changing from a transparent roof (glass/polycarbonate) to a solid tiled roof, this is considered a "change of use." In almost all cases, you **will** need to apply for Building Regulations approval from your local council. A reputable installer will handle this process for you. The structure must be proven to be strong enough to support the new (albeit lightweight) roof.
Frequently Asked Questions (FAQs)
How long does it take to replace a conservatory roof?
This depends on the material and complexity. A simple polycarbonate replacement can take 1-2 days. A glass roof might take 2-3 days. A full solid tiled roof replacement, including internal plastering, is a more involved project and can take 5-7 days.
Is a tiled conservatory roof worth the extra cost?
For most people, yes. While the initial investment is higher, a solid tiled roof provides the best insulation and usability, effectively giving you a new, comfortable room that you can use every single day of the year. This often provides the best long-term value and return on investment.
Can I put a solid roof on my existing conservatory frame?
In many cases, yes. Modern lightweight tiled roof systems are specifically designed to be installed on existing conservatory frames. However, your installer will need to conduct a survey to ensure your frames are structurally sound enough to support the new roof.
