Can a roof be inspected without scaffolding?

A lot can be judged without leaving the pavement or the garden. Slipped tiles, gaps at the ridge, a sagging roofline, dark streaks below a flashing and a broken gutter all show from a distance. Binoculars or a long camera lens bring a ridge or a chimney close enough to read, and nothing needs to be built to do it.

This first look also decides what comes next. On a bungalow, a ground view plus a ladder at the eaves may be all you need. On a tall house, it tells us whether a closer look is worth arranging. None of it costs you a scaffold, and it often shows whether a more involved check is needed at all. Plenty of owners are surprised how much a patient walk round the outside reveals, and a few minutes with a notepad and a phone camera gives a roofer a useful head start before the visit even begins.

A ladder set safely against the eaves lets a roofer view the lower courses, the gutter and the fascia at arm's length. A camera on an extending pole can look over a ridge or onto a flat roof edge without anyone climbing higher. Both leave the roof undisturbed, so no tile is cracked by a boot, and neither takes long to set up or pack away once the look is done.

The loft supplies the evidence from underneath. Daylight through the covering, damp timber, stained insulation and rot at the eaves are all visible from the hatch, and none requires access to the roof. Our guide on checking a roof from the loft shows what to look for. Between them, these methods cover most of a pitched roof.

For roofs that a ladder cannot reach safely, a drone is the usual answer. It flies above the roof and records every slope, so no one has to climb. How this compares with a ladder, and where each falls short, is set out in drone or ladder: which is better.

A mobile access tower is a lighter alternative to full scaffold. It gives a stable working platform at one spot, such as beside a chimney stack, and it can be wheeled to the next. For a short check at a single point it is often enough. The principle is that a survey needs a way to see, not a permanent structure wrapped round the house, with the hire cost and the disruption to your drive and your neighbours that come with it, and the simplest way to see is usually the right one.

Scaffold becomes necessary when the roof needs work done at height, such as replacing a section of lead or re-fixing a ridge on a tall house. Then it is a safety structure for the repair, not for the inspection. A roofer should explain the difference, and tell you when a quote includes it.

Should the scaffold sit on the footway or carriageway, the highway authority has to grant a licence under section 169 of the Highways Act 1980. West Sussex County Council wants a minimum of 10 working days from application to erection. For a two-storey semi-detached home, Checkatrade's October 2026 scaffolding table gives around £875 a month. Whichever firm you choose, ask whether the price shown includes VAT and scaffolding.

Before you agree to scaffold of any kind, ask what it is for. If the answer is only so that someone can look at the roof, ask what else could do the job. Ask who applies for the licence if one is needed, and how long that takes, because the notice period can hold up a start.

Ask, too, whether the total price you are given already includes the scaffold and how long it will stand. A reasonable roofer answers all of this in a sentence or two. If the answers are vague, the firm may be adding a structure to the job that the roof does not need.

Where it is safe, a roofer may walk the roof or lay a roof ladder over the slope to reach a flat section or a stack. That is the best way to test a ridge or press on a flashing. It is not always safe. Fibre cement sheets and rooflights can be fragile, and the Health and Safety Executive warns that people fall through them. Wet slates and moss also make a slope hazardous.

In those cases we use the other methods and do not step onto the roof. You still get photographs and a clear answer. See our roof inspections and surveys page, or how long a roof inspection takes, to plan the visit.
