Time on site

How long does a conservatory roof replacement take?

Time on site depends on the roof, the frame and the weather, so the survey sets it. Here are the stages, the waits before work begins and what to expect.

The short answer

The length of the job depends on the shape of the conservatory, what the survey finds under the old roof and the weather, so no figure from a table would fit your roof. We agree the expected working time on the survey visit and print it in the quote. Some of the waiting happens before anyone arrives: a contract you sign at home comes with 14 days to cancel, and a scaffold licence, where one is needed, has its own notice time.

What sets the time on site

Floor area alone does not set the time, because the roof is only part of the work. Six things shift the programme:

the shape, since a roof with a hip or several bays has more cutting and more edges to finish
the type of roof going on, because a solid roof is built up in layers while glazing is fitted in sheets
the frame, if the survey finds a repair or a support has to go in before the roof
the box gutters and the lead beside the house, which are either renewed with the roof or left as they are
the weather, because the room is open to it for part of the job
the inside, where a new ceiling lining and its finishing take time after the roof is closed in

Any one of these can change the length of the job, which is why a number of days copied from a website tells you very little about your own conservatory. We would rather give you a reasoned estimate at the survey than a round figure that the roof then fails to match.

The stages, in the order they happen

A conservatory roof replacement follows the same sequence on every job, whatever its final length. The order protects the room, the house and the budget, and it also explains why the job cannot be rushed at one stage to save time at another.

The survey and the written quote, with the expected working time stated.
The paperwork: the planning check, building control and, where scaffolding stands on the pavement, the licence.
Stripping the old roof, with the opening covered against the weather whenever work stops.
Any frame repair or support the survey called for.
The new roof structure, then the gutters and the lead beside the house.
The covering, the insulation and the ceiling lining.
Sweeping up, then a last walk round with you before we leave.

Stages one and two take place before the first day on site, so they add to the elapsed time without adding to the work. The old roof is not stripped until the new materials are ready to go on, which keeps the room open to the weather for as short a spell as the job allows.

The waits before work starts

Some delays are built into the rules. Signing the contract at home after our survey starts a 14-day cancellation window, and we start inside it only if you ask us to in writing. An urgent repair that you phone us out to carries no such cancellation right, but a roof replacement is a planned job, so the window applies to it.

Where scaffolding would stand on the pavement, the highway authority licenses it, and we arrange the licence with our scaffolder. Kent County Council asks for all applications, including renewals, to be submitted 5 working days before the intended start date. Kent County Council's scaffolding permit covers 7 calendar days and is priced at £52 per week for 2026 to 2027. East Sussex Highways lists £127 for 28 days, and says an extension is applied for at least five working days before expiry. A conservatory at the back of a house may need no pavement scaffold at all.

The planning check and building control are raised before work begins. Replies from councils are theirs to give, so those questions are put at the survey and not left for the first morning of the job.

Living with the work

While the roof is off, the room cannot be used, and the doors to it are best kept closed. The conservatory has to be emptied before we begin. Plants, furniture, blinds and anything fragile come out the day before, because dust and offcuts fall into an open room, and a cleared room also lets us carry materials straight through.

Rain can change a programme, and it is the one factor no one can schedule around in advance. When it is heavy we do not open a roof we cannot close again, and you hear about the delay as soon as it is known, not when the light has gone. Our guide to conservatory roof replacement costs explains what moves the written price, and the answer on solid conservatory roofs and building regulations explains the approval stage in more detail, including which building control body signs the work off. The whole job is described on the conservatory roofs page. Once the roof is finished the site is swept, and you are shown what was done before we leave.
