How long does a roof repair take?

A repair that stays in one place is quick work. Putting back a slipped tile, re-bedding a loose ridge section or clearing a blocked valley can be done in a single visit once someone is up there with the right materials. The job is short because nothing else has to be taken apart: the roofer finds the fault, fixes it and checks the neighbouring tiles for the same problem.

Small does not mean casual. A tile that has slipped because its nail has failed often has neighbours hanging on the same tired nails, and a careful repair looks along the whole course before it finishes. If the nails are tired across a full slope, the visit stops being a quick fix and becomes a different conversation, which our answer on nail sickness explains. The survey photographs tell you which kind of fault you have before anyone is booked in, so you can plan around it.

Anything that involves cutting and dressing metal takes more time. A flashing is a lead strip that weatherproofs the junction where a slope runs into brickwork. Replacing one means lifting the tiles beside it, taking out the old lead, cutting new sheet to fit, dressing it into the joint and putting the tiles back. A valley, the trough where two roof slopes meet, is similar: the tiles on both sides come up before the lining can be renewed.

Work like this is measured in days rather than hours, particularly on a chimney that needs access on all four sides, where each face has its own flashing to cut and dress. The length of the job grows with the number of joints, not the size of the house. Our lead roofing page describes what each stage involves, so you can see why a neat flashing is not something to hurry through.

When a ladder will not give safe access, scaffold has to be erected first, and that adds time at the front of the job. If it occupies any of the pavement, the highway authority must issue a scaffold licence first. West Sussex rules call for at least 10 working days between application and erection. Over the border, Hampshire sets ten clear working days, with the scaffold contractor applying for the customer.

That notice period can be longer than the repair itself. It is the main reason a roof that needs scaffold cannot always be mended in the week you first ring. A leak is a different case. An active leak jumps the queue, and the first visit aims to stop water coming in, often with a temporary cover, while the lasting repair is planned. Our page on repairs without scaffolding covers the jobs that can be reached another way.

Wind and rain hold up roof work more than people expect. Tiles and slates are not laid in a gale, and an open roof is not left exposed overnight, so a wet forecast moves the date. Flat roof coverings can be more sensitive still, because a membrane needs a dry surface to stick to. When the weather is the problem, the sensible course is to wait for a better day rather than patch over damp.

Materials matter too. A roof of old clay tiles or Horsham stone slabs, the heavy riven stone found on some older Sussex houses, may need matching pieces to be found, and that can take longer than the repair. Lead, plain tiles and standard fittings are easier to source. At the survey we tell you if the job depends on a special order, and the cost is stated in writing as one figure. Short winter days leave fewer working hours, which is part of why dates slip between November and February.

Ask for it in writing, next to the price. A useful estimate says how many days the work is expected to take on the roof, whether scaffold is needed and who arranges any licence, and what the plan is when rain interrupts the work. A roofer who will only say it depends is often dodging the question. A good one explains what it depends on, and gives you a likely range.

The survey is where that detail comes from. Pictures of your roof record how far the fault runs, and the quote that follows describes the work and gives a single total. If you want to see what drives the figure, our answer on what a roof repair costs sits alongside this one. Our roof repairs hub describes the full range of jobs, and booking the survey is the first step. It is also the point at which any tricky access, such as a steep rear slope or a roof behind a conservatory, shows up before it can surprise anyone.
