How long does a roof inspection take?

For a standard semi-detached or terraced house with one or two pitched slopes, the time on site is normally measured in a fraction of a morning rather than a whole day. A roofer walks round the outside, checks the covering, the ridge and hips, the verges and the gutters, looks at chimneys and flashings, and photographs anything that needs a record.

If the loft can be entered, that adds a separate stage. The underside of the slopes, the felt, the timbers and the insulation are checked with a torch, which is quick on a tidy loft and slower where boxes block the way. Our page on whether you need to be home explains how access affects the visit.

None of this is rushed. A good inspection is a methodical walk-through, not a glance, but a typical house does not need hours of poking about on the tiles.

Several things stretch the time. Size is the obvious one: a detached house with a long roof and several valleys has simply more to look at than a two-up two-down. Complexity matters as much, because dormers, bay roofs, extensions and a mix of old and new coverings each need their own look.

Access is the next factor. A roof that sits behind a locked gate, over a neighbour's yard or above a three-storey elevation needs ladders, towers or a drone, and setting them up takes longer than the looking itself. Steep pitches and wet or mossy slates slow things down for safety reasons, and rightly so.

Condition adds time, too. If a roof has several faults, each one needs a photograph and a note. A flat roof with ponding or blistering, or a loft with damp timber, means more to record and more to explain. A roof in good order really is quicker.

Flat roofs are often faster to walk, because there is a single surface and you can see the whole of it. But the checking is fiddly: laps, upstands, outlets, edges and any standing water all need attention, and our guide to flat roof condition surveys shows how much there is to cover.

Commercial and industrial buildings are another category. A big unit with rooflights, gutters and several levels can be a half-day or more, and may need a second person for safe access.

Specialist methods change the clock again. A drone sweep can capture a large roof in a short flight, though the pictures then need sorting; our page on drone roof surveys covers what a flight can and cannot show. Thermal and moisture surveys depend on conditions as much as on roof size, so the timing is less predictable.

The time on the roof is only the first part. Afterwards the photographs are sorted and labelled, the findings are written up, and the work needed is worked out into a written quote. That takes real time, and a report put together properly is worth waiting for.

Pictures from your own roof reach you with a written quote. A fixed turnaround would be a guess, because it depends on how much was found and what has to be priced. If something is leaking or unsafe, we deal with that first and make the roof safe before the paperwork.

Our page on whether you need a roof survey sets out when the whole process is worth doing and when a quick look will do.

People sometimes assume that a fast visit is a sign of efficiency, and a slow one a sign of padding. Neither is automatic. A roofer who spends a few minutes in the garden with binoculars is not inspecting the roof in any real sense. One who spends a long time on a small roof may be dealing with something awkward, or may simply be dawdling.

A fair test is whether you get evidence. Photographs of specific features, a note of what was and was not reached, and a clear view of what is urgent all show that time was used well. A verbal verdict from the pavement, however quick, gives you nothing to check.

Equally, do not be alarmed if a thorough job runs longer than you expected. Old roofs, shared valleys and awkward chimneys are slow to survey properly, and cutting corners saves nobody money in the end.

For planning, assume that the roofer will be about the property for a short while, will need the gate and loft hatch open, and will not need you hovering in the garden. Keep pets indoors, move cars away from the wall where a ladder will go, and have a quick word about any leaks you know about.

On price, MyBuilder's roof inspection guide, updated August 2026, lists a standard inspection at £150 to £250 and drone work at £200 to £400. Treat those as national averages, since the quote for your roof comes only after the survey. Our page on free roof inspections looks at what you get when someone offers a visit without a fee, and how a survey compares with an ordinary building survey.
