The short answer
Usually not. A pitched roof can normally be inspected from ladders, from inside the loft, from the pavement with binoculars, with a pole camera, and from a drone. A scaffold or access tower is added only when the roof has to be walked or touched, for example a high parapet gutter, a tall chimney stack or a slope too steep to stand on safely.
The ways a roof is reached for inspection
There is no single method. A roof inspection is a set of looks from different positions, and each position shows something the others miss.
Standing back with binoculars or a long lens, a roofer can read the overall shape of the roof: the line of the ridge, the pattern of the courses, missing or slipped coverings, moss, and the condition of chimneys and gutters. From a ladder at the eaves, the detail comes into focus: the state of the fascia, the first few courses, the gutter joints and how water is leaving the roof. From inside the loft, the underside tells a different story. Daylight through the covering, damp stains on the timber, a soft rafter end or a wet patch on the insulation each point to something that cannot be seen from outside.
Then there are the remote tools. A drone is flown above the roof to record each slope. A pole camera, held up on a telescopic pole, can look along a valley or over a parapet. Our page on loft roof inspection covers what the underside of a roof can reveal.
Which of these a survey uses depends on the pitch, the height, the covering and what the customer needs the inspection for.
When ladders and the loft are enough
A great many roofs are inspected with nothing more than a ladder and a torch. A two-storey house with an ordinary pitched roof and a clear eaves is the typical case. A ladder footed on firm, level ground reaches the gutter line and gives a close view of the lowest courses. Binoculars cover the rest of the slope, and the loft gives the view from underneath.
That combination is often enough to answer the usual questions. Are slates or tiles slipped, cracked or missing? Has the lead around the chimney lifted? Is the ridge sound? Is there a damp patch below a particular spot? If the answer to those is clear from the ground, the ladder and the loft, there is no reason to put up a scaffold just to look.
It also matters how a pitched roof is treated: it is not walked on without need. Slate, clay and stone tiles can crack under a boot, and a cracked slate is a new leak. A roof ladder or a long-reach view is gentler on the covering than walking across it, and where the covering is delicate we prefer to look from beside it rather than on top of it.
When a scaffold or tower earns its cost
Some roofs cannot be judged from a ladder. A scaffold or a tower is worth erecting when the inspection needs hands on the roof, or when the position of the roof makes any other approach unsafe.
- Parapet and box gutters. A parapet gutter is the metal-lined channel tucked behind a low edge wall, while a box gutter sits between two slopes. Neither is visible from the road, and checking the laps, drips and outlets means walking the run.
- Tall or leaning chimney stacks. Pointing, flaunching (the mortar bed the chimney pots stand in) and flashings are close work.
- Steep or tall roofs. A mansard, with its steep lower pitch below a flatter upper one, or a roof several storeys up, may offer no safe ladder position.
- Roofs that will be worked on straight afterwards. If a repair or a re-roof follows the inspection, the scaffold may be needed anyway.
On a replacement, scaffolding adds about £1,125 according to the MyBuilder new roof cost guide (2026), so it makes sense to share it between inspection and works rather than pay for it twice.
Drones and pole cameras
Where a roof is awkward to get at, a drone or pole camera can take the place of a scaffold. A drone gives a clear record of an entire roof, including slopes that cannot be seen from any public position. It is a good fit for tall buildings, large flat roofs and roofs with a complicated plan. Our drone roof survey page explains what the images show and what they cannot.
The limits are worth knowing. A drone shows what is visible from above: it will not feel a spongy deck, lift a lap of lead or reach into a gutter outlet. A pole camera can look into narrow places, but it has a short reach and sees only the part it is pointed at. Neither shows the underside of the roof, so they are paired with a look from the loft.
Used together, ground views, a ladder, the loft and a camera tool leave only a short list of places that really need hands. Those places are what a scaffold is for.
What access means for cost and for your records
Access is one of the cost drivers in an inspection. MyBuilder's roof inspection cost guide (2026) gives typical UK ranges of £150 to £500, with a standard inspection at £150 to £250, a drone survey at £200 to £400 and a thermal survey at £300 to £500. Treat them as national guides rather than an Empire tariff; the figure that applies to your house is set in writing once we have surveyed it.
If you have a report in mind for an insurer, a buyer or a lender, say so before the visit. The type of access decides what can be shown in the photographs, and a gap in the pictures is hard to fill later. For that purpose the roof report for insurance page lists what a useful report contains.
It also helps to clear access beforehand: move cars from beneath the eaves, leave side gates open, and make the loft hatch reachable. A roof that can be reached easily is inspected more thoroughly, and it is quicker too. Our survey costs nothing, and if your roof does turn out to need a scaffold we say why before anything is booked. For the full range, see roof inspections.
