Choosing the right conservatory roof type is one of the most important decisions you’ll make when building or upgrading a conservatory. It can shape everything from how much light the space gets to how warm your conservatory feels in winter and how well it connects with the rest of your home.
If you're in the process of gathering conservatory ideas, it's well worth understanding how each conservatory roof type performs in terms of insulation, appearance and practicality before you commit.
Conservatory Roof Types
In this guide, we explore the most popular conservatory roof types available today, from classic glazed options to solid tiled structures and hybrid designs. Calling on the experts, we’ll help you weigh up the pros and cons of each style, so you can choose a roof that suits your space and how you intend on using it.
Glazed Conservatory Roofs

The pros
Bright and open feel.
Advanced glass options improve efficiency.
Ideal for garden views and sky-gazing.
The cons
Can lead to heat gain/loss without the right type of glazing.
Requires more upkeep than solid alternatives.
Glass/glazed conservatory roofs remain the most popular choice for conservatory roofs, and it's easy to see why. “A glass conservatory roof maximises the natural light, creating a much brighter and airy space that feels connected to the outdoors,” says Karen Bell, sales director at David Salisbury. “Modern glazing technology improves insulation and reduces glare, making glass a more energy-efficient option than in the past.”
Sharon Wright, sales director at DHW Joinery, recommends using thermal and energy-efficient glass, such as Planitherm. “Thermally efficient glass roofs reduce sunlight and heat gain, keeping you cool in summer and warm in winter,” she explains. “You can even upgrade to self-cleaning glass that breaks down dirt and grime – ideal for lower maintenance.”
But while glazed roofs are extremely popular, they’re not always the most practical choice. As Mervyn Montgomery, managing director of Hampton Conservatories, explains: “Not every location and situation lends itself to an entirely glazed roof, despite this being one of the most distinguishing features of a conservatory. Even with modern technologies and methods to reduce excessive sunlight and inconvenient glare, some homeowners opt for a solid roof design instead.”
Tiled or ‘solid’ roofs have become increasingly popular, especially for homeowners keen to improve insulation and make their conservatory feel like an extension of the main living area,
“A solid roof helps to maintain a stable indoor temperature year-round,” explains Lisa Morton of Vale Garden Houses. “They also provide increased privacy and reduce glare – perfect for home offices or sun-facing locations.”
According to Sharon Wright, “a tiled roof is the most durable and lowest maintenance option, offering lower U-values and improved energy efficiency than standard glass roofs. However, they usually cost more and don’t deliver as much sunlight.”
Hybrid Conservatory Roofs

The Pros
Blends light and thermal control.
Versatile for different conservatory styles.
Great for both new builds and conservatory roof replacements.
The cons
Complex designs may add to installation time and costs.
May require careful planning.
If you want to flood your space with plenty of light but you don’t want to impact your conservatory’s thermal efficiency, a hybrid conservatory roof offers the best of both worlds.
“These designs deliver the energy-efficiency and durability of solid roofs with some of the natural illumination of a glass roof,” explains Sharon Wright from DHW Joinery. “This makes them particularly appealing for modern conservatories that serve as multifunctional living spaces, where comfort is key but you still want to enjoy a light-filled atmosphere.”
Though less common in new builds, polycarbonate roofs are still a familiar sight in older conservatories. Their main appeal lies in being lightweight, and relatively inexpensive and easy to install, which made them a popular choice in the past. However, their performance often falls short when it comes to insulation and noise reduction.
“These types of conservatory roofs can suffer from heat gain in summer and heat loss in winter,” explains Karen Bell from David Salisbury. “They’re generally being phased out in favour of better insulated options.” As a result, many homeowners with ageing polycarbonate roofs are now opting for a conservatory roof replacement to improve energy efficiency and create a more comfortable space.
While they might suit short-term or budget-conscious projects, polycarbonate roofs are rarely recommended for modern conservatories, especially if you're looking to design a conservatory that adds value to your home.
If you’re looking for something more architectural than your average glazed roof, a flat solid roof with a statement roof lantern could be just the thing. This style of roof is perfect for anyone wanting their conservatory to blur the lines between traditional add-on and full-on extension. The crisp, clean lines of a flat roof lend themselves beautifully to modern homes, while a lantern overhead draws in light and drama.
Mervyn Montgomery from Hampton Conservatories, points out that this type of structure is also a smart solve for more complicated layouts. “It can be a challenge to attach a fully octagonal conservatory to a host property,” he explains. “So this is often resolved by providing a link passageway either pitched and glazed or with a flat solid roof with glazed sides.”
FAQs
How much does a conservatory roof cost?
Prices can vary widely depending on the size of your conservatory and the type of roof you’re installing. At the lower end of the scale, a polycarbonate or basic glass conservatory roof might cost between £2,500 and £5,000. For something more substantial like a tiled or hybrid roof, you could be looking at £6,000 to £15,000 or more.
Getting a few quotes from trusted installers is always a good idea, and be sure to factor in things like lighting, ventilation, and any structural work if you are repairing an existing conservatory roof or replacing an older one.
Can I replace an old conservatory roof with a different type?
Yes, and it's one of the easiest ways to improve the comfort, insulation and style of your conservatory. Swapping out a dated polycarbonate roof for a glass, tiled or hybrid version can make a dramatic difference to your space. The most important thing to check is whether your existing conservatory structure can support the weight of a new, heavier roof. Tiled roofs especially need proper reinforcement. Most reputable companies will carry out a structural survey as part of the process.
Which roof is best for energy efficiency?
If keeping your conservatory warm in winter and cool in summer is the goal, solid tiled roofs are your best option. They offer superior insulation and help reduce heat loss and solar gain. That said, high-spec glazed roofs can still perform well, especially if you choose thermally efficient glazing like low-e or solar control glass – both of which allow you to enjoy all the benefits of natural light without sacrificing any of the comfort.
Avoid polycarbonate if energy efficiency is a priority for you. These types of roof may be lightweight but they are not known for their thermal performance.
Do I need planning permission to change my conservatory roof?
In most cases, no – replacing your conservatory roof like-for-like or upgrading to a different material doesn’t usually require planning permission. But there are a few exceptions. If your home is listed, in a conservation area, or the roof design will significantly alter the exterior appearance or height, it’s worth checking with your local planning authority.
You should also consider Conservatory Building Regulations, especially if you’re installing a solid roof. This kind of upgrade might count as turning your conservatory into a permanent extension, so it needs to meet certain insulation and structural standards. A good installer will guide you through what’s required. Read our guide to when a conservatory becomes an extension for more details on this.
