Source: Checkatrade, figures shown on 29 October 2026 for conservatory roof conversions, Maidstone. Identical figures appear for at least one town outside Kent, so treat them as a guide to the wider region, not a Maidstone-only price.
A figure like this mixes small lean-tos and large P-shapes, simple glazing swaps and full tiled conversions. It is useful for checking whether a budget is in the right area. It cannot tell you what your own roof will cost.
Why roof quotes differ
- Shape and size: a lean-to is simpler than a Victorian roof with several facets or a P-shape with a valley.
- The option chosen: a tiled roof with a plastered ceiling involves more materials and trades than new glass.
- Frames and base: repairs or strengthening found at survey stage add to the total.
- Roof windows and glazed sections: each one adds parts and labour.
- Inside finishes: plastering, decorating, downlights and sockets are sometimes priced separately.
- Guttering and drainage: new gutters, fascias and downpipes, especially where a neighbour is close.
- Approvals: Building Regulations fees, and any planning steps in a conservation area or Article 4 place.
- Access and waste: getting materials to the back garden and taking the old roof away.
Roof chooser
Which roof suits your conservatory?
Five quick questions about the room. The chooser suggests which options to look at first and which checks to raise. It shows no prices, and it is a starting point rather than advice about your house.
Look at
Checks to raise
A general guide only. A firm that has seen your conservatory can advise on what it will take.
Setting a sensible budget
Decide first what the room is for, because that decides the option, and the option drives most of the cost. Then allow for the extras that apply to you: a roof window, a new ceiling light, a gutter that has to be rerouted, or a frame repair the survey turns up.
Be cautious about a price far below the rest. Savings on a roof tend to come from the parts you will never see again once the ceiling is plastered: the beam, the insulation, the membrane and the sealing. A slightly simpler roof built properly beats an ambitious one built cheaply.
Comparing quotes fairly
Give each firm the same facts: the shape, which way it faces, the current roof material, what bothers you and what you would like instead. When quotes arrive, check they include the same roof system, the same ceiling and electrics, the same guttering and the same waste removal, and say who handles Building Regulations. Only then compare totals. The Maidstone guide sets out seven questions worth asking.
Our request form covers those same details, so it doubles as a checklist.
Cost questions
Why does my quote differ so much from the average?
Averages blend very different jobs. Shape, size, the option chosen and anything found at survey can put a quote well above or below it.
Is new glass always cheaper than a tiled roof?
Usually, but not always. A large or complicated glass roof with a new frame can approach the cost of a simpler tiled one. Ask for both if you are unsure.
Do firms charge to survey?
Practice differs. Ask when you first make contact.
