Do you need scaffolding to repair a stone roof?

With a plain tile roof, people ask first whether a ladder will reach. On stone, the more useful question is where a person can stand without harming the roof. Horsham slabs are thick, rough and uneven, and each one sits on its neighbours at a slight tilt. Put weight on the wrong corner and a slab can crack or shift, and a one-slab fix becomes a bigger bill.

The slopes are often steep and the courses graded, with larger slabs low down and smaller ones near the ridge. That makes a stone roof harder to walk than a plain tile roof, and the weight of the covering means it cannot take a crowd of people and materials on it. Our guide to stone roof weight explains why the frame matters so much.

So the working rule is simple. Build the access first, then do the repair from it. Standing on the stone itself is for the brief inspection that decides whether access is needed, and little else.

A scaffold built along the eaves gives a level platform at the foot of the roof, with edge protection so nobody falls. From there, a roofer can lift slabs by hand, pass new stone up and carry waste down without stepping on the covering. Heavy material is the other half of it: slabs, battens and lead need getting to the roof and off it, and scaffold with a hoist or a stepped platform does that safely.

It also protects the house. Gutters, fascias and walls are not knocked by ladders leant against them, and a roof being worked on over several days stays covered and watertight at the end of each one. For jobs near a chimney, a swept valley or a lead abutment, the scaffold lets the roofer reach the whole detail from one place.

Our answer on roof repair without scaffolding explains the limited cases on other roofs where it can be done. A stone roof makes those cases fewer.

Not every job calls for a full scaffold. A single cracked slab low on a side that is easy to reach may be dealt with from a tower or a properly set ladder. Studying the slopes from the lane, a window or the loft hatch needs nothing built at all.

The line between the two is drawn by the height, the slope, the condition of the roof and the work being done. A job where the roofer has to lift and relay slabs for any distance, work at a valley or chimney, or leave the roof open overnight, is a scaffold job. Better that the survey tells you so than a crew arriving to find the job cannot be done safely.

If you are weighing a tower against a full scaffold, ask what the plan is for the slabs that come off, and where they will be stored. It is an easy question, and the answer shows whether the roofer has thought the job through. Our stone roof survey answer explains how the first visit works.

Checkatrade's scaffolding guide puts a monthly hire at roughly £875 for a two-storey semi, with a terrace around £800, a detached house around £1,200 and a detached bungalow around £1,000, and about £660 a week for a chimney. These are typical UK figures from that guide, which says its table was last updated in October 2026. Your own price depends on the shape of the building and how long the scaffold stays up.

Section 169 of the Highways Act 1980 makes a licence compulsory where scaffolding gets in the way of the road or pavement. Round Horsham the licence comes from West Sussex County Council: ten working days between applying and putting poles up, and £266 for a month. Our guide to the scaffold licence in West Sussex covers the process.

Poles standing only on your own land are a separate case from poles on the pavement. Whoever quotes, ask if the price carries scaffolding and VAT, since a total that leaves them out will rise later.

Here is the order of the survey: slopes from outside, timbers from inside the loft, then photographs of every fault, so the way in is chosen with the evidence in hand. Where scaffold is needed, you hear it with the reason. The written quote then follows, with one total for the whole job, so there is no separate bill to chase.

The plan also takes in the neighbours and the garden. A scaffold needs a footing, a clear route for material and a way of keeping the property secure while it is up. These are settled before a date is fixed, so the day the scaffold goes up is no surprise to you or next door.

For the work that follows, our Horsham stone roofing page sets out the repairs and relays we carry out, and our repair or relay answer explains how we decide between them.
