The short answer
Not always. A low or gently pitched roof can often be treated from a ladder or a tower, but a tall or steep one may need full scaffolding for the work to be done safely. Where scaffold obstructs the public highway, a Highways Act 1980 licence comes first.
Ladders, towers and platforms
The right access is the lightest that makes the work safe. A porch, an extension or a single-storey roof can often be reached by a ladder to the eaves, plus a roof ladder to spread weight and give secure footing. A tower, a wheeled frame carrying a platform, can reach a two-storey eaves line where the ground is level and clear.
For roofs where the treatment can be applied from below, a long-reach lance or pole from the ground does away with the need for anyone to climb. It suits straightforward slopes where the spray can be controlled. A mobile access platform, the sort with a boom, is another option where there is room for it to stand and the ground can take its weight.
The choice depends on the height of the eaves, the pitch, the width of the slope, the ground beneath and how close the neighbours are. We decide it at the survey, and we explain why we picked it. If a cheaper option would be unsafe, we say what the safe one is and why it matters.
Access is set up before anyone treats a tile. Ladders are footed or tied, boards go down on the slope, and everything is checked before the weight goes on.
When full scaffolding is the answer
Full scaffolding comes into play on tall houses, on steep or complicated roofs with dormers and valleys, and where the treatment is only part of a larger job that also needs repairs. It gives a stable platform along the whole eaves, edge protection and a safe route up. It also lets the gutters be cleared, the fascias checked and tiles replaced while the structure is in place.
The extra cost is real, and it shows in the total. If the roof also needs a repair, such as new ridge mortar or replacing slipped tiles, sharing one scaffold across both jobs is far better than paying for access twice. We look for that at the survey, so the plan can cover the clean and the repair together if you wish.
Where scaffolding is used, it is part of the written total, not something added afterwards. Ask any firm whether access is included, as it changes the comparison between quotes.
Our answer on what a roof cleaner charges explains how access and other factors move the price.
The highway licence
Section 169 of the Highways Act 1980 puts a licence requirement on scaffolding that obstructs a highway, and the pavement or road in front of a house is one. Hampshire County Council and West Berkshire Council both say private land and private roads need none.
For Andover the licensing body is Hampshire County Council. Hampshire County Council wants the scaffolding company to apply for its customer, with ten clear working days in hand. Hampshire County Council's fee is £211.90 on application for the first 2 weeks, then £72 for each further 2 weeks.
Across the Wiltshire border, the company supplying the scaffolding applies to Wiltshire Council on its MiPermit portal. Wiltshire Council charges £143.80 or £164.70, depending on the notice given, and a licence lasts 28 days. In West Berkshire the scaffolding provider applies to West Berkshire Council, which charges £125 plus £71 per week.
Those fees use different units and should not be compared directly. Where the house sits under any other authority, the scaffolder and our team arrange the licence together before the date is fixed.
Safety and what to do before the visit
Falls are the principal danger in roof work, so access is a safety matter first and a cost matter second. Please do not offer your own ladder or climb up to save a few hours. A roof ladder looks simple, but it has to be hooked over the ridge correctly and used with the edge in mind.
Before the visit, clear cars and bins from the walls and tell us about gates, overhead cables and boundaries. If the scaffold will take up the pavement, the licence conditions cover signs, lighting and a safe walkway for pedestrians, and the scaffolder handles them.
The licence notice period can affect the start date, so it helps to arrange the survey early if you want the work done at a particular time. Short-notice requests sometimes cost more or are not possible, and a wet or windy week can also push a booking back.
We keep things tidy: access is taken down when the work finishes, waste is cleared and the site is left as we found it. The roof cleaning and moss removal page covers the treatments themselves, and after the survey the written price you get is one total, access included.
