Buyer's Guide
Most conservatory roof replacements in Yorkshire land between £4,500 and £18,000 fitted. Where you sit in that range depends on the roof type, the size and shape of your conservatory, and how much of the existing structure can be reused. Here is how the numbers break down, in plain terms, so you know what a fair quote looks like before you ask for one.
| Roof option | Typical fitted cost |
|---|---|
| Solid (tiled) roof | £7,000 - £18,000 |
| Solid roof with roof windows | £8,500 - £20,000 |
| Replacement glass roof | £4,500 - £11,000 |
| Polycarbonate replacement | £2,500 - £5,500 |
| Flat roof conversion | £6,000 - £15,000 |
Ranges are indicative UK market guide prices for a typical 3m x 3.5m conservatory, including installation. Your own quote depends on survey findings. We give fixed written prices after a free site survey.
The cheapest roof is rarely the best value. Think about how you want to use the room, then pick the roof that makes that possible.
£7,000 - £18,000
A fully insulated, lightweight tiled roof that turns a conservatory into a year-round room. The warmest option and the most popular replacement we fit.
£8,500 - £20,000
The same insulated tiled roof with Velux or roof lantern glazing added, keeping natural light while cutting heat loss.
£4,500 - £11,000
Modern self-cleaning, solar-control glass fitted into a new or existing frame. The lightest-touch upgrade if you like the bright, garden-room feel.
£2,500 - £5,500
A like-for-like sheet replacement. The cheapest fix, but it does little for comfort in summer or winter.
£6,000 - £15,000
Converting a tired conservatory or lean-to into a warm flat roof with a plastered ceiling and optional rooflights.
Two conservatories of the same size can be thousands apart. These are the six things that move the number most.
A 3m x 3m lean-to is far simpler than a P-shaped or Victorian roof with multiple facets and valleys. Complexity adds labour and materials.
If the frames and dwarf wall are sound, they can often carry a new roof. If not, allow for new frames, a strengthened ringbeam or base repairs.
A plastered, skimmed and decorated ceiling with downlights costs more than an unfinished internal liner, but it is what makes the room feel like part of the house.
Solid roof replacements normally need building control sign-off and structural calculations. Budget for the local authority fee on top of the installation.
Roof windows, lanterns, solar-control glass and self-cleaning coatings all shift the price, and all change how the room feels day to day.
Restricted side access, scaffolding or working over a conservatory full of furniture can add a day or two of labour.
A conservatory that is too hot in July and too cold in January is a room you use for maybe four months of the year. Replacing the roof is almost always cheaper than building an extension of the same footprint, and it buys back the other eight months.
The insulation gain is the real return. An insulated solid roof dramatically reduces heat loss compared with old polycarbonate, which shows up on your heating bills and in how the room feels the moment you walk in.
Estate agents generally treat a properly converted, year-round room as usable living space in a way that a dated conservatory is not. If you plan to sell, that matters.
Plan for the roof itself, the internal finish (plastering, decoration, lighting) and the building control fee where one applies. Getting all three into your budget from the start avoids the classic surprise of a finished roof and an unfinished ceiling.
Most installers, ourselves included, work to a staged payment structure: a deposit at order, the balance of the product before delivery, and the installation fee on completion once you are happy with the work. Never pay the full amount upfront.
Ask any installer three things: is the quote fixed or an estimate, who handles building regulations, and what exactly the guarantee covers. Our work carries a 10 year guarantee, and we manage building control for you.
Free survey, fixed written quote, no pressure.
