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

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

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

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

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

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

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.
They suit different conservatories and different budgets. None of them is automatically the right answer.

Premium
An insulated solid roof replaces the existing one, so the room reads as part of the house rather than a glazed box. The biggest change, and the biggest job.

Mid-range
A replacement glazed roof, for people who want to keep the light overhead and the open feel, with modern glazing units.

Lower cost
Replacement polycarbonate sheeting. The lower-cost route of the three shown here for a roof that has failed, leaked or discoloured.

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

Four things decide which option suits a conservatory. None of them is the roof on its own.
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.
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.
How much overhead light you want to keep is a genuine choice rather than a technical question.
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.

Not sureFrom the first visit to the quotation.

Step 1
We come out and assess the conservatory before quoting. The quotation follows the visit and discussion of the requirements and options.

Step 2
We tell you what your conservatory actually needs. If the cheaper roof solves it, we will say so.

Step 3
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.
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.
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.
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.
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.
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.
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.
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.
A few quick questions so we arrive knowing what we are looking at. There are no wrong answers, and "not sure" is a real answer - we will work it out during the quote visit.
