Scaffolding and Roof Access: What It Costs and Why It Matters

Work at height regulations require a safe working platform for anything beyond short duration, low risk tasks. Replacing a slipped tile from a properly footed ladder can be legitimate. Stripping a roof, rebuilding a chimney or repointing a ridge cannot.

There is a quality argument as well as a safety one. A roofer standing on a stable platform with materials to hand works accurately. A roofer stretching from a ladder rushes and reaches, and the details suffer, which is exactly where roofs leak.

If a contractor offers to do a substantial job without access equipment because it saves you money, that is a signal about how the rest of the work will be done.

A straightforward domestic scaffold to one elevation on a two storey house typically costs £700 to £1,200. Wrapping two or three elevations, or reaching a three storey property, generally pushes it to £1,200 to £2,500.

That price normally includes erection, a hire period and dismantling. Standard hire is often four to eight weeks, and overruns are charged weekly, which is one reason a contractor who turns up and works continuously saves you money.

Chimney work often needs a scaffold that goes above the ridge with a working platform around the stack, which costs more than an eaves-level scaffold to the same house.

If any part of the scaffold stands on a public footpath or road, the local authority requires a licence. That costs money and takes time to arrange, typically one to two weeks, so it needs building into the programme.

On terraces with rear lanes, access for the scaffold wagon has to be checked in advance. A lane blocked by parked cars on the morning of the erection costs a wasted day.

If the scaffold needs to stand on a neighbour's land or oversail their property, you need their agreement in advance. Most neighbours are reasonable if asked properly and unreasonable if surprised.

A mobile tower is appropriate for gutter clearance, fascia inspection, a single roof window from inside, or small localised repairs at eaves level. It is much cheaper and quicker to set up.

A cherry picker or MEWP suits work on a commercial building or where a scaffold cannot be erected, and it is hired by the day. It is often the sensible answer for a single inspection or a small high level repair.

Roof ladders and safety systems have a place for short duration work on a pitched slope, used by trained operatives with fall protection. They are not a substitute for a platform on any job lasting more than an hour or two.

Access is the strongest reason to bundle roof work. If the scaffold is going up for a re-roof, get the chimney repointed, the roofline replaced, the gutters renewed and any rooflight fitted while it is there.

Doing those jobs separately over three years could mean paying for access three times, which can add well over a thousand pounds for no benefit whatsoever.

When we survey we deliberately look for everything that would benefit from the same scaffold, list it, and price it separately so you can decide. There is no obligation to take it all, but you should at least know what it would cost while the opportunity is there.

Scaffolding is a security consideration. Keep upstairs windows locked, move ladders and garden tools out of sight, and tell your insurer if it will be up for an extended period, as some policies ask you to.

Expect some disruption to the garden and driveway. A good scaffold crew protects surfaces and sets base plates on boards, and a good roofing firm cleans up daily rather than at the end.

Arrange the dismantle promptly once the work is signed off. Standing scaffold costs money and there is no reason to keep it beyond the final walk round.
