Why Replace Your Conservatory Roof?
Most conservatories were built with polycarbonate or early double-glazed roofs. Over time these cause the same problems:
- The room is too hot in summer and too cold in winter to use comfortably.
- Condensation, green algae or staining builds up on the panels.
- Seals, gaskets and flashing fail, and the roof leaks.
- Rain on the roof is very loud.
- Panels turn brittle, yellow or cracked with age.
If your conservatory feels like an outdoor room rather than part of the house, replacing the roof is often the biggest improvement you can make, without rebuilding the whole structure.
Conservatory Roof Replacement Options
The right roof depends on how you use the room, the strength of your existing frame, and your budget. Delete any option below that you don’t fit.
| Roof type | Best for | What to know |
|---|---|---|
| Solid tiled roof | A room you want to use all year, like a living room or dining room | Looks like the rest of the house. Usually needs Building Regulations approval (see below). |
| Lightweight insulated roof | Upgrading an old frame without adding much weight | Insulated panel systems fitted onto a suitable existing frame. |
| Replacement glass roof | Keeping a bright, open feel | Modern glass can include solar control and self-cleaning coatings. |
| Replacement polycarbonate | A short-term or lower-cost fix | Cheaper, but doesn’t match the warmth or quietness of a solid roof. |
| Glass roof with solid sections or skylights | A balance of light and insulation | Part solid, part glazed. |
We’ll tell you honestly which option suits your conservatory. Some conservatories can take a heavier tiled roof, and others need a lightweight system or a frame upgrade first.
Solid Roof or Glass Roof: Which Is Better?
Choose a solid tiled roof if you want a room that feels like part of the house all year, with better insulation, less noise in the rain and a more consistent temperature.
Choose a glass roof if you want the open, bright feel, and you’re happy to manage some temperature swings. Modern solar control glass reduces summer heat, but it won’t insulate as well as a solid roof.
Many customers choose a solid roof with roof windows or skylights so the room still feels light. We can talk through the balance on the survey.
Signs Your Conservatory Roof Needs Replacing
You probably need a new roof, not just a repair, if:
- Several panels are cracked, discoloured or loose.
- The roof leaks in more than one place, or the same leak returns.
- The roof is sagging or the frame is flexing.
- The room can’t be used in summer or winter.
- Moss, algae or condensation keeps returning between panes.
If you only have a single leak, a repair may be enough. See our roof leak repair service in London. If you’re unsure what’s causing it, our guide to the signs of a leaking roof explains what to look for.
Our Conservatory Roof Replacement Process
- Survey: We check the roof, the frame, the base and the walls, and discuss how you use the room.
- Options and advice: We explain which roof types suit your conservatory, and whether the frame needs work.
- Written quote: You get the price, materials, scope and timeframe in writing before work begins.
- Building control: If your chosen roof needs Building Regulations approval, [we arrange it / we guide you through it].
- Removal and fitting: We remove the old roof and fit the new one, protecting the interior, e.g. “Most replacements take 1 to 7 days
- Finishing and checks: We fit flashings and guttering connections, inspect the finished roof and leave the site tidy.
Do You Need Planning Permission or Building Regulations?
This depends on the roof you choose. The rules below are general, so always check with your local authority.
Planning permission: Replacing a conservatory roof is often permitted development, but conditions apply. Properties in conservation areas, and listed buildings, often have extra restrictions. The Planning Portal explains when a roof change may need consent.
Building Regulations: Conservatories are often exempt from Building Regulations if they’re mostly glazed and separated from the house. Fitting a solid roof usually changes that, so a replacement solid roof normally needs approval. The new roof must be structurally safe, properly insulated and ventilated, and your existing conservatory structure must be able to support the extra weight.
We’ll tell you which rules apply to your project. We work with your local building control team.
If your home is in a conservation area (for example Hampstead, Belsize Park, Kensington or Chelsea), see Historic England’s guidance and speak to your local planning authority before work begins.
Can We Keep Your Existing Conservatory Frame?
Often, yes. A well-built frame in good condition can take a new roof. We check:
- The frame’s strength and condition, including any rot, corrosion or movement.
- The base, dwarf walls and foundations, especially if a heavier roof is planned.
- Whether the frame needs strengthening, or whether it’s better replaced.
If a new roof wouldn’t be safe on your frame, we’ll say so, and explain the alternatives.
What Affects the Cost of Conservatory Roof Replacement?
The price depends on the roof type, the size and shape of the conservatory (a Victorian or P-shape costs more than a simple lean-to), the condition of the frame, access for materials and scaffolding, and whether Building Regulations approval is needed.
We don’t quote by phone for this. We survey first, then give you a written, itemised price. That way you know what’s included before any work begins.
Ask us to quote at the same time for any related work, such as guttering, fascias and soffits, so scaffolding and access aren’t paid for twice.

Conservatory Roof Replacement FAQs
How much does conservatory roof replacement cost?
It depends on the roof type, the conservatory’s size and shape, the condition of the frame and access. We survey first and give you a written quote before any work begins.
Do I need planning permission to replace a conservatory roof?
Often not, as it’s frequently permitted development, but conditions apply. Conservation areas and listed buildings may have extra rules, so check with your local planning authority.
Do I need Building Regulations approval for a solid conservatory roof?
Usually yes. A solid roof removes the exemption most conservatories have, so the new roof must meet structural and energy efficiency standards. We’ll explain what’s needed for your project.
Can I fit a new roof to my existing conservatory frame?
Often yes, if the frame is strong and in good condition. We check the frame, base and walls first, and tell you if anything needs strengthening.
How long does conservatory roof replacement take?
Most replacements take 1 to 7 days, depending on size and roof type. We give a realistic timeframe with your quote.
Is a solid roof better than a glass roof?
It depends on how you use the room. A solid roof usually insulates better and is quieter in the rain. A glass roof keeps the room brighter. We’ll talk through both on the survey.
Will a new roof make my conservatory more comfortable?
Usually, yes. A better-insulated roof helps keep heat in during winter, and options like solar control glass can reduce summer overheating. The result depends on the roof type and the existing glazing and frame.
Can a leaking conservatory roof be repaired instead of replaced?
Sometimes. A single failed seal or flashing can often be repaired. If the panels are cracked or the roof leaks in several places, replacement usually makes more sense. See our roof leak repair service.
