The honest answer to what a conservatory roof costs is that it depends on what goes on top and what lies underneath. Two conservatories of the same footprint can be priced far apart because one has a sound frame and easy access while the other needs strengthening and scaffolding. The only way to a true figure is a survey, but you can understand the shape of the price beforehand. This guide sets out the one typical UK range we can source for a solid tiled roof, then walks through the factors that move a quote up or down, so that you can read the quotes you receive and compare them fairly. Treat these as national figures reported by a cost guide, useful as a guide to scale and no more. Your fixed quote follows the survey, and it is the only number that applies to your roof.

The typical UK range for a solid tiled roof

One UK cost calculator puts a solid tiled conservatory roof at roughly £6,100 to £15,000, or £650 to £1,200 per m². Treat that as a typical UK range reported by a third-party guide and not as a Beacon price list. The spread is wide because the variables are wide: a small lean-to with a simple pitch sits at the lower end, while a large P-shaped or Victorian conservatory with hips, a finial and a complicated wall junction sits much higher. A figure per square metre also hides items that do not scale with area, such as scaffolding, building control and the work to the frame.

We have not found a sourced typical range for glass or polycarbonate replacement that we are willing to quote, so we do not give one. Those roofs vary with glazing specification and the framing they are fixed to, and a made-up number would mislead you. What we can say is that a lighter sheet or glazed system has fewer stages and needs no insulation layer, tiles or plastered ceiling, which is why it usually costs less than a solid roof. Your quote will show the figure for your chosen system.

What pushes the price up or down

Quotes differ for reasons that can be traced. Going through them in turn gives you a checklist for comparing any two quotes.

The system you choose

A solid tiled system involves rafters or a prefabricated frame, insulation, a breathable membrane, battens, lightweight tiles, trims, lead flashings, a plasterboard ceiling and decoration-ready finish. A glass or polycarbonate system replaces a covering on an existing structure. More components, more labour days and more trades means a higher cost, and that is simply what a solid roof is. If you are still choosing, the comparison on glass, polycarbonate or solid conservatory roofs shows what each gives you.

Size and shape

Area sets the base cost, but shape adds to it. A simple lean-to is one slope. A Victorian or Edwardian conservatory with a faceted front has hips, valleys, a ridge and a finial, and every hip and valley is a detail to be formed and flashed by hand. A gable-front or P-shaped plan adds junctions where one roof meets another. Each junction is an additional place for a leak if it is done poorly, so it takes time to do well.

The condition of the frame

If the existing frame and base walls can take the new roof, the work goes ahead. If the frame needs strengthening, or timber has rotted, or a perimeter beam must be added, that is extra work. Our guide to the frame and foundation checks for a solid roof describes what we look at. We flag any frame work during the survey, and we do not discover it halfway through the job without telling you.

Access and scaffolding

A conservatory in the middle of a back garden with side access is simple. A conservatory under a first-floor window, hemmed in by a boundary fence, or reached only through the house, needs more time and equipment. Scaffolding is a real line in many roofing quotes, so ask whether it is included and how long it is hired for.

Insulation and the finished ceiling

The thickness and type of insulation, the ceiling finish and any extra items such as spotlights or roof windows change the price. Our page on insulating a conservatory roof compares panels with replacement and shows how the choice affects what you pay.

Building control and other fees

A solid roof replacing a translucent one needs a Building Regulations application, because the structure must take the extra load. Building control fees are a real cost, and so is any structural calculation they ask for. Some roof systems are assured or registered, which can speed approval, but they do not remove the need for it. We handle the Building Regulations side where the work is notifiable, and your quote states whether fees are included or passed on at cost. A listed building or a conservation area may add a planning step, which is the subject of our guide on planning permission for a conservatory roof.

Reading a quote properly

When two quotes for the same conservatory differ by thousands, the gap usually lies in what each includes. A quote worth comparing states, in writing:

  • The exact system and make, with a description of the tiles or glazing.
  • Whether the frame is assessed and what is allowed if it needs work.
  • Scaffolding or access equipment, and the hire period.
  • Insulation type and the internal ceiling finish.
  • Building control fees and who applies.
  • Lead flashings at the house wall and new gutter work.
  • Removal of old materials and clearing the site.
  • The guarantee, in writing, and what it covers.

A very low price often leaves out exactly the items on that list that cost the most, so that they appear later as extras. A fixed written quote is meant to stop that. Ours names what is included and what is not, and the figure does not change unless you ask us to change the scope.

Repair versus replace: the cheapest roof is the one you do not need

Not every tired conservatory needs a new roof. A leak at a failed seal, a slipped panel or a blocked gutter is a repair, and a repair costs a fraction of replacement. We tell you when a roof has years left in it. Our guide on leaking conservatory roofs explains the common causes, and the answer on whether a conservatory roof can be repaired rather than replaced sets out how we decide. Where the cause is a poor wall junction, a new flashing can end the leak without touching the roof.

Where replacement is the better call, the cost is spread across a long working life. A solid roof can also change how the room is used through the year, which is the thought behind our guide on turning a conservatory into a year-round room. If you are thinking about selling, the page on conservatory roofs and selling your house looks at whether the spend comes back.

Running costs and the value of the room

Purchase price is only part of the picture. A conservatory with a translucent roof can be too hot in summer and too cold in winter, and many owners stop using it for half the year. A solid insulated roof changes that, because the temperature stays steadier, and heating becomes more feasible. We do not promise a saving on energy bills, because the result depends on the glazing, the walls, the floor and how you heat the room. What we can say is that a room you use all year gives more for the money than one you avoid in January and July, and that is the real comparison to make when you weigh the price.

What the roof price does not include

A roofing quote covers the roof. It does not normally cover redecorating the room, new flooring, blinds, furniture, heating or electrical changes beyond what the roof needs, so keep those in a separate budget. The same goes for the cost of any work that the survey shows is needed outside the roof, such as cracked base walls or failed door seals. We list these as separate items so you can see them, and we do not fold them into a headline figure to make it look larger or smaller.

Two practical questions are worth asking every firm. First, who is on site and who is accountable if something goes wrong? Second, what is the guarantee, who stands behind it and is it in writing? A price comparison that ignores those answers compares only half of what you are buying.

How to get a price you can rely on

Start with a free survey. We go up and look at the roof, check the frame and the wall junction, and photograph what we find, so you see your own conservatory rather than a generic example. After that you receive a fixed written quote for the system you choose, with the extras separated out so you can say yes or no to each. If the survey shows a repair will do, we say so. The work carries a 10-year workmanship guarantee in writing, and we clear the site and take the old materials away.

Related questions

Why is a solid conservatory roof priced so much higher than a polycarbonate one?

A polycarbonate roof is a covering fixed to an existing structure. A solid roof is a new structure: rafters or a prefabricated frame, insulation, membrane, battens, tiles, lead flashings and a plastered ceiling, plus a Building Regulations application. More materials, more labour days and more trades all add up. The solid roof also changes how the room performs through the year, which is what many owners are paying for.

Is scaffolding included in a conservatory roof quote?

It should be stated either way. On a low conservatory with open side access, a tower or podium may do, while a conservatory under a first-floor window usually needs full scaffolding. The hire period matters too, because delays for weather can extend it. Ask each firm to name access equipment and hire time separately, so you compare the same thing in every quote.

Can the price of a conservatory roof change after I accept the quote?

A fixed quote should not change unless the scope does. The usual reason for a change is hidden damage found at strip-out, such as rot in a wall plate, and in that case we stop, show you photographs and agree the extra in writing before carrying on. Nothing is added without your say. If you choose a different system or add roof windows after accepting, the quote is revised for that change only.
