How Long Does a Roof Repair Take?

The simplest jobs are quick. Replacing a few slipped or broken tiles, re-bedding a loose ridge tile, or clearing and refixing a gutter is often done in a single visit, as long as the roof is dry and the access is straightforward. A temporary make-safe, such as a cover over an opening, is quicker still.

Which repairs take longer?

Anything that involves cutting out and rebuilding takes longer. A valley, the V-shaped channel between two slopes, has to be stripped back, relined and re-covered. Lead flashings round a chimney have to be cut, formed and fitted to the structure. Replacing rotten battens, the timber rails that carry the tiles, means lifting a section of the roof before it can be put back.

No fixed number of hours suits every job, since a roof that looks like a ten-minute fix from the ground often turns out to be larger once the covering is lifted. Repairs on slate, clay or old lead can take longer again because the materials need to be sourced and matched. The survey tells you which kind of job yours is, and it is better to hear a realistic answer before work begins than a hopeful one.

Getting to the roof can take as long as the repair. A low roof within easy reach of a ladder poses few problems. A three-storey house with a chimney at the ridge may need scaffold, and scaffold has to be ordered, delivered and erected before roofing starts. If the frame stands on the pavement, the licence process adds waiting time of its own.

Does scaffold slow an urgent job down?

It can. Somerset Council wants at least 10 working days' notice before a licence is issued, and only emergency applications are dealt with on shorter notice. For that reason, roofers often make the opening safe from the best access available, then plan the permanent repair around the scaffold. Our answer on scaffolding for emergency repairs explains the options.

Give the roofer three facts at the first call: how high the house is, what is below the eaves and whether it fronts the road. They let a visit be planned and a sensible estimate of the job length be given. Parked cars, narrow lanes and tight gardens all have their effect, so mention them too, along with any access through a neighbour's land.

Roofing is done outdoors, and rain, strong wind and frost can stop work. Slate and tile cannot be laid safely on a wet, windy slope, and flat-roof membranes and mortar need dry conditions to bond. A job started in good weather can pause for a day or two when the forecast turns, and the roofer should tell you before that happens, not after.

Why can a repair run into a second visit?

Sometimes the view from the ground misses a fault. Taking off a slate may show rotten battens, torn underlay or damaged lead beneath, and fixing them takes longer than replacing the one tile. Sometimes the materials are not on the van. Matching a clay tile or a particular slate may mean ordering it in.

Inside the house, timbers and plaster can take a while to dry after the roof is sealed. Staining on a ceiling can reappear if it is repainted too early, so allow the building to dry first. Our answer on roof repairs in high winds says when work should wait, and the emergency roof repairs hub covers what to do in the meantime.

You should know what is happening on each visit. After the survey, you see photographs of your roof, and the repair is described: what the job involves, and how long it should take on a normal day. If part of the work depends on the weather or on materials being ordered, that is explained at the start and not after the van has left.

Will it be fixed on the first visit?

Often the leak can be stopped in one visit, even when the permanent repair needs another. Our page on fixing a leak on the first visit covers when that is realistic and when it is not.

Stopping the water comes first; the proper repair follows. The site stays tidy and safe, waste is taken away, and each day ends with a word on tomorrow's plan. That is the practical meaning of a timetable: no surprises, and a clear picture of the following step.

Send a photo of the fault along with the address. The survey then leads to one written price, and a timescale you can plan your week around.
