Which Conservatory Roof is Right for You? A Practical Guide for Hampshire Homeowners

If your conservatory roof is past its best, you have more options today than ever before. Glass, polycarbonate, tiled and solid roofs all serve different needs, and choosing the wrong one can leave you with a room that is still too hot in summer or too cold in winter. This guide honestly breaks down the differences, so you can go into any conversation with a fitter knowing exactly what you want.

The problem with the roof you already have

Most conservatories built before 2010 have a polycarbonate or basic glass roof. Both were designed to let light in, not to keep heat in. The result is familiar to most conservatory owners: a room you abandon in January because the heating bill is too high, and avoid in July because it is unbearable.

The good news is that the roof is the problem, not the room. Replace it with the right product and the same space can become one of the most comfortable rooms in the house.

Your three main options

Glass conservatory roofs

A glass roof maximises natural light and keeps the open, airy feel that many people love about a conservatory. Modern solar control glass performs significantly better than older versions, reducing glare and heat build-up compared with polycarbonate. If natural light is your priority and you already have good blinds or curtains, a glass roof can work well.

The trade-off is thermal performance. Even high-specification glass cannot match a solid or tiled roof for insulation, so heating costs in winter tend to remain higher. Glass roofs also amplify rainfall noise, which some people find pleasant, and others find distracting.

Best for: homeowners who want to preserve the light-filled, traditional conservatory feel and are not using the space as a primary living room.

Tiled conservatory roofs

A tiled roof is the closest thing to a proper house extension roof. It sits on a lightweight aluminium frame rather than the existing timber, and is finished with slate-effect or standard roof tiles that can be matched to your property. The thermal performance is dramatically better than glass or polycarbonate, and rain noise is eliminated.

Most tiled roof installations include one or two Velux-style roof lights to bring in natural light, so the room does not feel dark. The result is a space that behaves more like a proper room and less like a greenhouse.

If you want to understand the full installation process and what a professionally fitted tiled roof looks like in practice, our page on tiled conservatory roofs covers this in detail.

Best for: homeowners who want excellent insulation, a low-maintenance finish, and a conservatory that integrates visually with the main house.

Solid conservatory roofs

A solid conservatory roof combines the thermal performance of a tiled roof with the option to include glass panels and a plastered interior ceiling. The result is a room that is genuinely warm in winter, cool in summer, and finished to the same standard as the rest of your home inside.

The Guardian Warm Roof is the solid roof system we fit at Guardian Installations. It uses a lightweight aluminium structural frame, exterior-grade boarding, a breathable waterproof membrane and a premium tile finish – all installed directly onto your existing conservatory structure without a full rebuild. Internal ceiling options include a smooth plastered finish or a vaulted ceiling with inset downlights, depending on what suits your property.

Because the room performs like any other room in the house once the Guardian Warm Roof is fitted, many of our customers also take the opportunity to add new windows or bifold doors at the same time, opening the conservatory up to the garden in summer.

You can read more about how the system works and what the installation involves on our dedicated solid conservatory roofs page.

Best for: homeowners who want to turn their conservatory into a year-round room that is indistinguishable from the rest of the house in terms of comfort and finish.

How to choose between them

The honest answer is that it depends on how you use — or want to use — the room.

If the conservatory is primarily a place for plants and occasional summer use, a glass or polycarbonate roof may be perfectly adequate, and a replacement in the same material will be a lower-cost fix.

If you want to use the room throughout the year — as a dining room, home office, playroom, or second sitting room — a solid or tiled roof is the only option that delivers the thermal performance to make that realistic. The Guardian Warm Roof is particularly well suited to this because the interior finish matches the rest of the house, rather than feeling like an afterthought.

For most homeowners in Hampshire who contact us, the answer is a solid roof. The upfront cost is higher than a polycarbonate replacement, but the room becomes genuinely usable for twelve months of the year rather than four or five.

What about planning permission?

In most cases, a like-for-like conservatory roof replacement does not require planning permission, provided the conservatory’s footprint and height do not change. Replacing a glass or polycarbonate roof with a solid tiled roof on an existing structure typically falls within permitted development rights.

There are exceptions — if your property is in a conservation area, a listed building, or has had permitted development rights removed, you should check with your local planning authority before proceeding. Extensions built from scratch that include a new solid roof may require LABC building control sign-off. Guardian Installations handles LABC compliance for all applicable projects as standard.

If you are unsure whether your project needs permission, get in touch and we can advise based on your specific property.

What does a conservatory roof replacement cost?

Costs vary depending on the size of your conservatory, the roof type you choose, and whether any additional work is involved such as new windows, doors or internal finishing. We do not publish fixed prices because every project is different, and a quote based on your actual conservatory will always be more accurate than an online price guide.

What we can tell you is that a solid or tiled roof replacement represents a significant uplift in your home’s usable value. A conservatory that adds genuine living space is worth more than one that sits empty for eight months of the year.
