A conservatory can be one of the best investments you make in your home, extra living space, more natural light, and a room that connects you to the garden all year round. But the single biggest factor in whether your conservatory actually gets used (or ends up as a glorified storage room) comes down to one thing: the roof.
At Elmhurst Windows, we’re asked about conservatory roofs more than almost any other topic. So we’ve put together this guide to help you understand your options, the benefits of each, and what to consider before you commit.
Why the Roof Matters More Than You Think
Conservatories have a reputation problem. Too hot in summer, too cold in winter, noisy when it rains, these are the classic complaints. Almost all of them trace back to the roof.
A poorly insulated or outdated roof lets heat escape in winter and turns your conservatory into a greenhouse in summer. The good news is that modern roofing technology has completely changed what’s possible, meaning your conservatory can be a comfortable, usable room in every season.
Types of Conservatory Roofs
1. Glass Conservatory Roofs
Glass roofs remain the most popular choice, and for good reason. Today’s glazing units use advanced coatings and multi-layer glass to:
- Reflect heat away in summer
- Retain warmth in winter
- Filter harmful UV rays that fade furniture and flooring
- Reduce outside noise, including rain
Glass roofs also let in significantly more natural light than alternatives, which makes them a favourite for anyone wanting their conservatory to feel like a genuine extension of the home rather than an add-on.
2. Tiled Conservatory Roofs
A tiled (or “solid”) roof replaces glass panels with lightweight, insulated tiles that match your existing roofline. Benefits include:
- Excellent thermal performance, usable year-round
- A more seamless look with the rest of the house
- The option to add roof lights or lantern windows for extra brightness
- Often makes the room feel more like a “proper” extension for planning and mortgage valuation purposes
3. Polycarbonate Roofs
Common on older conservatories, polycarbonate roofing is budget-friendly but falls behind on insulation and noise reduction compared to modern glass or tiled options. If you have one of these, it’s usually the first thing worth upgrading.
Replacing an Old Conservatory Roof
You don’t need to replace your entire conservatory to fix a roof that isn’t performing. A conservatory roof replacement is one of the most cost-effective home improvements you can make, and typically involves:
- Removing the existing roof structure
- Fitting a new, insulated frame if needed
- Installing modern glass or tiled panels
- Sealing and finishing to current building standards
Many homeowners find their conservatory becomes usable for the first time in years — no longer too hot to sit in during summer or too cold to bother with in winter.
Key Benefits of Upgrading Your Conservatory Roof
- Year-round comfort – enjoy the space in every season, not just spring and autumn
- Lower energy bills – better insulation means less heat loss through the roof
- Increased home value – a functional, well-insulated conservatory adds genuine square footage
- Reduced noise – modern glazing dramatically cuts down rain and wind noise
- UV protection – keep furniture, flooring and fabrics from fading
Things to Consider Before You Choose
- Orientation: South-facing conservatories need extra solar control glazing to avoid overheating
- Planning permission: Most conservatory roof replacements fall under permitted development, but it’s worth checking, especially for tiled roofs that alter the roofline
- Budget: Glass roofs and tiled roofs vary in cost, get a tailored quote rather than relying on national averages
- Building regulations: Roof replacements on existing conservatories may need to meet current thermal efficiency standards

Frequently Asked Questions
How long does a conservatory roof replacement take? Most replacements are completed within a few days, depending on the size and complexity of the roof.
Can I replace just the roof without rebuilding the conservatory? Yes, in most cases, the existing frame and walls stay in place while only the roof structure is replaced.
Is a tiled roof better than a glass roof? Neither is universally “better”, it depends on how you want to use the space. Tiled roofs offer the best insulation and a house-like feel, while glass roofs maximise natural light.
