The short answer
Sometimes. An urgent roof repair needs scaffolding when the damaged spot cannot be reached safely from a ladder, for example high up a steep slope, beside a chimney or in a valley. Plenty of make-safe jobs, such as re-seating a slipped tile or sheeting a hole, can be done from ladders or a tower. If the scaffold would occupy part of the pavement or carriageway, permission from the highway authority comes first.
How we decide between a ladder, a tower and full scaffold for an urgent repair, and what the licence and cost involve.
When a ladder is enough and when it is not
The question we ask first is simple: can someone stand and work safely at the damaged spot? On a bungalow, or along the lower edge of a house roof, a ladder fitted with a stabiliser bar and footed by a second person may do. The same goes for a single slipped tile near the eaves, or a short run of torn underlay, which is the sheet beneath the tiles.
Higher up, the picture changes. A hole halfway up a tall slope, a failed chimney flashing, a broken valley or a badly displaced ridge all put a roofer far from any safe footing. A ladder with a hook that grips the ridge can help on a plain slope, yet it is a poor answer where tiles are already loose or wet. In those cases a tower or a lift of scaffold is the safer route, because it gives a flat platform, edge protection and room to carry materials.
A good roofer tells you which it is and why, after studying the roof from outside and from the loft hatch. If a ladder is enough, you should not be sold a scaffold you do not need.
Scaffold on the highway needs a licence
Section 169 of the Highways Act 1980 covers scaffolding on or over a public road or pavement, and the highway authority has to grant permission first. For most of our area that means West Sussex County Council or Surrey County Council, with East Sussex and Kent at the edges. Scaffolding set up entirely on your own land, for instance a front drive or rear lawn, needs no licence; the council cares about the pavement and the road.
Who files the paperwork varies. Kent's county council expects the scaffold firm to be the applicant, acting for the customer. West Sussex and Surrey do not say either way on the pages we checked, so the licence is something we work through jointly with the scaffolding firm, so put the question of who applies to every firm before agreeing.
Expect conditions. Surrey, for instance, asks for a layout drawing and proof of public liability cover, and charges £208 for each 28 day period. West Sussex lists £266 for one month of scaffolding. These are the councils' published fees, they are liable to change, and your authority's current page is the one to check. Parking bays outside the house may need suspending too, which is a separate request.
How quickly can emergency access be arranged?
The answer depends on the licence, not only on the scaffolders. West Sussex wants a minimum of 10 working days from application to erection, and Surrey asks applicants to apply at least 10 working days before the start date. Kent says 5 working days. A scaffold that must overhang a public pavement therefore cannot always go up the same week as the leak.
There are routes for genuine urgency. West Sussex offers a fast-track application for an extra £52, and asks you to email the licensing team before applying. Surrey invites a phone call when danger to the public makes the standard wait unacceptable.
Meanwhile the roof still has to be made safe. That is why we begin with what can be done from ladders, a tower or a cherry picker: a temporary cover, re-seated tiles, a patched hole. The permanent repair can then wait for proper access without the house taking in water in the gap. Our guide to what a roof make-safe involves sets out the steps in order.
What emergency scaffolding costs and who pays
Checkatrade's roof replacement guide, last updated in October 2026, puts scaffold for a whole new roof at £700 to £1,300, from putting it up to taking it down. That is a national yardstick, not a price for your home. The actual figure turns on the number of elevations, the height, whether the scaffold sits on a pavement and the licence fee that comes with it.
Scaffold is often the largest single item on a small repair, so it makes sense to look over the rest of the house while it is up. If the gutter, a fascia board or a chimney on the same side needs attention, getting it done in one visit usually costs less than erecting access twice. Tell us about everything you have noticed when you call.
After the survey you get a single total price on paper. Whatever quote you receive, find out if it covers scaffolding and VAT. If you plan to claim on your home insurance, tell the insurer before work starts and keep the receipts. Our answer on emergency roof tarpaulins covers the cover-up that often buys time, and the wider emergency roof repairs page shows how the work is organised.

Two scaffold questions
Can the scaffolders put it up without a licence?
Only if it stays on private land. A scaffold that sits on the pavement or the road, or that blocks it, requires the highway authority's consent, and putting one up without it can mean extra charges and a retrospective application. Ask the scaffolder to confirm in writing whether a licence is needed and who is applying.
Is a scaffold tower enough for a small urgent repair?
Often, yes. A tower gives a firm platform for a job at the eaves, a gutter bracket or a low flashing, and it is quicker to set up than a full lift. It is not suited to a hole high on a steep slope or work around a tall chimney, where a proper scaffold with edge protection is the safer choice.
