Conservatory roofs

Conservatory roof replacement

Solid, glass or polycarbonate. Which one is right depends on your conservatory and what is actually wrong with it, so we look first and tell you straight.

What are you trying to change?

Recognising what you want to change is a useful starting point, but which roof suits it depends on the conservatory.

  • The roof is leaking or failing

    Water getting in, panels slipping, seals gone, or a roof that has simply reached the end of its life.

  • Too hot in summer, too cold in winter

    The room is only comfortable for part of the year, so it sits unused for the rest of it.

  • Rain noise

    Heavy rain on the existing roof makes the room hard to sit in or hear the television in.

  • Condensation or damp

    Streaming panels, damp patches or a musty smell that keeps coming back.

  • You want to keep the daylight

    The room is bright and you want it to stay that way, whatever else changes.

  • You want it to feel part of the house

    Less like a conservatory bolted on the back, more like an ordinary room you use all year.

Tell us what the issues are and how you want to use the room, and we’ll tell you what solution we recommend.

How the three compare

A rough orientation, not a specification. The existing structure is assessed before any of them is recommended.

What we look at before recommending a roof

Four things decide which option suits a conservatory. None of them is the roof on its own.

  • The existing structure

    The frames, base and existing glazing are checked before any option is recommended. If the glazing or framework would also benefit from upgrading, CSM can include that work at the same time as the roof replacement, rather than treating it as a separate job later.

  • How the room is used

    A room you want to sit in all year is a different brief from one used for storage or plants. What actually bothers you about it matters more than the label on the roof.

  • Daylight

    How much overhead light you want to keep is a genuine choice rather than a technical question.

  • The shape of the conservatory

    Lean-to, Victorian, Edwardian, gable, P-shaped and T-shaped are the familiar forms. Most can be considered for replacement where the structure is suitable, and you do not need to know which yours is.

These are the usual forms, seen from above. You do not need to know which one you have to get in touch — it is confirmed during the quote visit, and plenty of people have no idea whether theirs is Edwardian or Victorian.

How we work

From the first visit to the quotation.

  1. Step 1

    We look first

    We come out and assess the conservatory before quoting. The quotation follows the visit and discussion of the requirements and options.

  2. Step 2

    We explain the sensible options

    We tell you what your conservatory actually needs. If the cheaper roof solves it, we will say so.

  3. Step 3

    You get the quotation

    A no-obligation quotation for the scope that has been agreed.

We cover the North East — north into Northumberland as far as Alnwick, and south to Teesside.

Questions about conservatory roof replacement

Do I need to replace my entire conservatory if the roof is failing?

Usually not. If the existing frames and base are sound and suitable, the roof can often be replaced without rebuilding the whole conservatory. The existing structure needs to be assessed first.

What types of conservatory roof can be replaced?

CSM works with polycarbonate, glass and warm or solid conservatory roof replacement systems. Which replacement is suitable depends on the existing structure, how the room is used and what you want to change about it.

Which conservatory roof is right for my home?

There is not one roof that is right for every conservatory. The existing structure, how much natural light you want, how you use the room, the problems you want to solve and your budget all matter. That is why we look at the conservatory before recommending an option.

Can I keep my existing conservatory windows and frames?

Often, yes, provided the existing frames and structure are sound and suitable for the replacement roof. Their condition and suitability are checked before the roof specification is agreed.

Do I need planning permission to replace my conservatory roof?

Not always. Roof replacement on an existing conservatory can often be carried out without a planning application, but the position depends on the property and the work. Listed buildings, conservation areas, restricted permitted development rights or more substantial alterations can change what is required. Planning permission and Building Regulations are separate questions, so both need to be considered before work starts.

Will I need Building Regulations approval?

It depends on the roof and the work. The conservatory exemption may no longer apply where the work significantly reduces the amount of glazing to the roof, as a solid or insulated roof usually does. Whether an existing conservatory remains exempt is case-specific and is determined by Building Control.

How long does conservatory roof replacement take?

The programme depends on the roof type, size, shape, access and the condition of the existing conservatory. We confirm the expected programme after the conservatory has been assessed.
