The short answer: if work involves height, lasts more than a few minutes, needs both hands, or involves carrying materials, a scaffold is usually the right call.
Ladders are for access, not for working from. Below, each type of work has an honest verdict rather than a blanket yes.
Send us a photo of the property and a line about the work. We will tell you honestly whether you need a scaffold and what it would cost.
Roofing and chimney work
Roof replacements
A full strip and re-cover always needs scaffolding. Tiles have to come off, waste has to come down and new material has to go up, all day, for weeks.
What suits it: a scaffold to every elevation being worked, top lift at gutter height with the guardrail above the roof line for edge protection, and a loading bay where materials will land. A temporary roof if the structure will be open.
Safety: nobody should work at the eaves without edge protection. See our roofer's guide for lift heights and loading.
Roof repairs
A handful of slipped tiles low on a garage roof may be reachable from a tower. A repair to a pitched roof on a house is scaffold work, and often faster because the roofer can move properly.
What suits it: a single elevation scaffold with a gutter lift, or a small tower for genuinely minor low level work.
Safety: repairs have a habit of growing once the roof is opened up. Scaffolding means that is not a problem.
Chimney repairs
Repointing, reflaunching, rebuilds and pot changes all need a stable platform at stack level with room to work around it and land materials.
What suits it: a scaffold to the elevation plus a chimney platform above roof level. Our roofing and chimney access scaffolds are built for exactly this.
Safety: chimney work involves heavy, unstable material at the highest point of the building. It is not ladder work.
Dormers
Forming or repairing a dormer means structural work at roof level with joinery, roofing, leadwork and glazing all needing access.
What suits it: a scaffold with a lift at dormer cill level and another for the roof, plus protection for the opening while it is formed.
Safety: open roof structures need weather protection and a clear edge treatment.
External finishes
Rendering
Render has to be applied in continuous passes to avoid joins. That means the whole elevation reachable at once, at a comfortable working height.
What suits it: full elevation scaffold with lifts at roughly 1.8m intervals so the renderer can work in bands. See painting and rendering access.
Safety: render is heavy and wet. Loaded platforms need the right duty rating.
External painting
Anything above ground floor windows benefits from scaffolding. It is quicker, the finish is better, and there is no repositioning a ladder every two metres.
What suits it: multiple lifts so the decorator can reach the full height, or a tower for a single ground floor elevation.
Safety: painting takes two hands and long periods in one position, which is precisely what ladders are worst at.
Repointing
Raking out and repointing brickwork is slow, repetitive work with tools and mortar in both hands, across the whole elevation.
What suits it: a full elevation scaffold with closely spaced lifts. Sheeting or netting if the property faces a pavement.
Safety: dust from grinders is a real hazard. A boarded platform allows extraction and containment to be set up properly.
Cladding
Cladding is a panel by panel installation with materials that need two people and careful alignment.
What suits it: scaffold with lifts set to the panel module, plus a loading bay for the boards or sheets.
Safety: large panels catch the wind. Erecting them from ladders is not an option.
Brickwork
New brickwork and repairs above the first metre or so need a platform that rises with the work, with room for bricks and mortar alongside.
What suits it: an independent scaffold with lifts raised as the courses go up, or a bricklayer's scaffold designed for the load.
Safety: materials stacked on a platform must not exceed its duty rating. Tell your scaffolder the loads.
Roofline, guttering and services
Guttering
Clearing a single gutter run on a bungalow can be done safely from a tower. Replacing gutters on a two storey house, or working on a long run, is scaffold work.
What suits it: a scaffold with a single lift just below gutter level to the elevations being worked.
Safety: the moment someone is leaning sideways off a ladder with a length of guttering, the job has gone wrong.
Fascias and soffits
Full replacement means removing old boards, checking rafter feet, fitting new boards and often gutters at the same time. It is continuous work along the whole roofline.
What suits it: a gutter level lift along each elevation, extended past the verges.
Safety: rotten timber is often found once boards come off, so having a platform makes the extra work simple.
Solar panel installation
Panels are heavy, awkward and expensive, and installers work on the roof slope for hours. Nearly every installer will require scaffolding before they book the job.
What suits it: a scaffold with edge protection above roof level and a loading point for panels. See solar panel access.
Safety: panels acting as sails in a gust is a genuine risk. Roof edge protection is not optional.
Structural work and openings
Loft conversions
Weeks of work involving roof alterations, dormers, windows, insulation and finishes, with materials going up and waste coming down throughout.
What suits it: a scaffold designed for the whole programme, with lifts for roof and dormer level and a loading bay. See loft conversion scaffolding.
Safety: plan the hire period generously. These programmes almost always move.
Extensions
Once an extension goes above ground floor level, the brickwork, roof structure, roofing and finishes all need access, often with the main house scaffold bridged over the new structure.
What suits it: phased scaffolding that follows the build sequence, with beamed bridging where needed. See scaffolding for extensions.
Safety: never support a scaffold off a new or partly built structure.
Window replacement
Ground floor windows are usually fitted from inside. First floor and above need external access to fit, seal and finish the outside of the frame safely.
What suits it: a scaffold with a lift at cill level for each floor being replaced. See window fitting access.
Safety: old frames come out in one piece and are heavy. A platform makes that controllable.
Maintenance and repairs
External maintenance
Small, brief, low level tasks may not need a scaffold. Anything at height, anything lasting more than a short period, and anything involving tools or materials does.
What suits it: a short duration scaffold, or a rolling programme where a property is maintained regularly. See property maintenance.
Safety: the temptation to do "just one quick job" off a ladder is where most falls happen.
When you can manage without
Scaffolding is not always the answer. A tower or a properly footed ladder can be reasonable for changing a single light, brief inspection work, a short gutter clear at single storey height, or accessing a low flat roof.
The test is simple: how high, how long, how much can you carry, and what happens if you lose balance. If any answer makes you pause, hire a scaffold.

FAQs
Is scaffolding a legal requirement?
The law does not name scaffolding specifically. It requires work at height to be properly planned and the most suitable equipment used. For most roof, render and roofline work, that is a scaffold.
Can I use a tower instead?
For short, low level tasks on firm level ground, sometimes yes. Towers give a small working area, cannot carry much material and have to be moved constantly, so they suit brief jobs rather than programmes of work.
Do I need scaffolding for a single storey bungalow?
For a re-roof or render, yes. Even at single storey height the work is continuous and materials need landing. For a quick gutter clear, a tower may be enough.
Who decides what scaffold I need?
In practice it is a three way conversation between you, your trade and us. Tell us what work is planned and we will design the access around it. See our hiring guide for the questions to ask.
