Upgrade Your Conservatory Roof: Calculate Costs Easily, No Sales Pressure

Conservatories are a beloved feature in many UK homes, offering a bright and inviting space to relax while enjoying views of the garden. However, a conservatory is only as functional and comfortable as its roof allows it to be. The type of roofing you choose can significantly impact the insulation, energy efficiency, and year-round usability of your conservatory. Selecting the right conservatory roof isn’t just about aesthetics; it’s an essential investment in the comfort and value of your home.


Choosing the right roof can make a conservatory a four-season space that remains comfortable in both summer and winter. In this guide, we’ll explore the types of conservatory roofing available, factors to consider, costs, and benefits to help you make an informed choice.

Planning Permission for Conservatory Roofing

When is planning permission required?
In the UK, planning permission for a conservatory depends on several factors, including the size of the conservatory and its proximity to your boundary lines. If your conservatory falls within permitted development rights, it may not require planning permission. However, when it comes to replacing or adding a roof to an existing conservatory, the rules can vary.


Do you need planning permission to put a roof on a conservatory?
In most cases, adding a solid roof to an existing conservatory does require planning permission because it can change the building’s classification from a ‘temporary’ to a ‘permanent’ structure. Local regulations ensure that any roof modification meets thermal efficiency standards and structural integrity requirements, protecting your home from potential issues down the line.


What are the new conservatory laws in the UK?
Recent changes in UK conservatory laws focus on improving energy efficiency. For example, new solid conservatory roofs must adhere to strict U-value (thermal performance) standards to ensure that they provide adequate insulation, making them usable all year round.

Types of Conservatory Roofing

Glass Conservatory Roofing

Glass roofs are a classic choice, known for letting in maximum sunlight and creating an open, airy feel. Many homeowners prefer glass roofs for their ability to bring the outdoors in, making them ideal for sun-filled mornings or evening stargazing.

  • Pros: High light transmission, modern aesthetic, range of glazing options
  • Cons: Potential for heat buildup in summer, can be harder to insulate
  • Maintenance: Regular cleaning to maintain clarity and avoid algae buildup

Modern glass roofs often come with advanced glazing options that improve insulation and UV protection, reducing glare and keeping the conservatory cooler in summer and warmer in winter.

Polycarbonate Conservatory Roofing

Polycarbonate roofs are a popular budget-friendly option. This material is lightweight, making it easy to install, and it’s known for its durability.

  • Pros: Affordable, strong and weather-resistant, easy to install
  • Cons: Less insulation than other materials, may be noisy during rain
  • Energy Efficiency: Somewhat limited, but still effective for seasonal use

Polycarbonate is especially suitable for households looking for a cost-effective solution or those who don’t use their conservatories year-round. However, newer polycarbonate materials have improved thermal insulation compared to older options.

Solid Tiled Conservatory Roofing

Solid tiled roofs are the go-to choice for homeowners who prioritize insulation and privacy. These roofs use materials similar to those on the main house, like tiles or shingles, and are highly effective at retaining heat

  • Pros: Excellent insulation, strong soundproofing, can blend with main home’s roof
  • Cons: Reduced natural light, higher cost, heavier installation process
  • Design Flexibility: Can be customized with skylights or glass panels for added light

Solid roofs make conservatories suitable for use throughout the year and provide a more consistent temperature, helping to transform a seasonal conservatory into a true extension of the living space.

Hybrid Conservatory Roofing

Hybrid roofs combine elements of solid and glass roofing, offering a balanced approach for homeowners who want insulation without sacrificing natural light.

  • Features: Glass panels embedded in solid roofs, or vice versa, for versatile use
  • Advantages: Good insulation, partial light transmission, custom design
  • Popularity: Increasingly favored for its versatility and stylish appearance

With options for custom skylights or glass panels, hybrid roofs are a modern choice for those looking to create a unique conservatory environment.

How much does conservatory roof insulation cost?

Conservatory roof insulation typically costs anywhere from £2,000 to £10,000. Costs will vary greatly depending on the type of insulation being installed, the materials used, the size of the conservatory roof, and your choice of installer.


For example, when retrofitting a conservatory with a solid roof, the type of finish you choose for the roof will affect the price. Felt roofing is typically the cheapest option, while roof shingles are the most expensive.


When installing internal conservatory roof insulation, the choice of finish will also affect the cost. A uPVC finish will be cheaper than a wooden one, for instance.

Lifespan of Conservatory Roofs

The lifespan of your conservatory roof depends heavily on the materials used.

On average:

  • Glass roofs last 15-20 years, though they may need repairs due to leaks.
  • Polycarbonate roofs typically last around 10-15 years before showing signs of wear.
  • Solid tiled roofs are the most durable, lasting 50+ years with proper maintenance.

Signs that your conservatory roof may need replacing include leaks, condensation, excessive noise during rain, and fluctuating temperatures.
