Roofers insurance in London
The classic London roof is not a simple pitch. Behind the parapet of a Victorian or Edwardian terrace there are usually two slopes falling inward to a central valley gutter, draining through a single outlet, hidden from the street and from the owner. When that gutter blocks or its lining fails, the water does not run off the building — it ponds and goes inside. A roofer in London spends a great deal of time inside that detail.
Everything else follows from density. The next building is a few feet away or physically attached; the pavement below is public and busy; scaffolding and skips need a licence from the borough before they touch the highway; and the flat roof you are stripping is the ceiling of somebody’s occupied flat. Add mansard conversions, rear extensions, conservation areas across most of the inner boroughs, and emissions and parking rules that shape what vehicle you can bring and where it can stand.
The exposure that produces claims is proximity. Falling material has somewhere to land, hot work has something to catch, and an open roof has occupied rooms directly under it. Apex is a Bristol-based commercial broker and we arrange cover that reflects how the trade actually works, placed by a named broker who will present your risk properly to insurers who understand it.
Key covers for roofers
- Public liability — the core cover — injury to a passer-by from falling material, damage to a neighbouring property inches away, and water damage to the flat beneath an opened roof.
- Employers’ liability — legally required once you employ anyone, including labour-only sub-contractors, which is how most roofing gangs are made up.
- Tools and plant — theft from site, van or yard — a persistent problem where vehicles are parked on street and material is stored at ground level.
- Contract works — your work in progress against fire, storm, water and vandalism before hand-over, which is what stands between you and a bad night with an open roof.
- Hot works — torch-on felt, hot-air welding and lead burning subject to permit and fire-watch conditions — the highest-consequence condition in a terrace where the neighbour’s timber is on the other side of a party wall.
- Professional indemnity or a financial loss extension — where you survey, specify or advise, particularly on valley gutters and flat-roof build-ups where the argument is usually about design.
- Personal accident — optional cover if injury stops you working.
Valley gutters, party walls and the public highway
The valley behind the parapet. The inward-sloping twin-pitch roof with a central gutter is the standard covering on huge numbers of London terraces, and it is the source of a disproportionate share of the water-ingress work in the city. The gutter is invisible from the ground, drains through one outlet, fills with debris, and when it overflows the water goes into the building rather than off it. Repairs and relining are frequently done above occupied rooms with limited access, and disagreements about whether a lining has failed or been overwhelmed are common.
Density and party walls. Terraced and semi-detached stock means the building you are working on is physically joined to the one next door. Hot works, cutting, fixings and scaffold loads all reach the neighbour, and a neighbour who is not your client is exactly the sort of third-party claimant a liability policy exists for.
Public highway everywhere. Almost any scaffold, hoarding or skip touches the footway or the road, which requires a licence from the relevant borough and brings pedestrian management duties with it. Failing to license properly does not void a policy by itself, but it materially weakens any defence when someone is injured passing your work.
Mansards, extensions and flat roofs over homes. Loft conversions and rear extensions have put a great deal of flat and low-pitch roofing directly above occupied rooms. Stripping one means exposing somebody’s ceiling to the weather for as long as the work takes, and temporary protection is the whole of the risk control.
Conservation areas and vehicle rules. Much of inner London sits within conservation areas that constrain materials and detailing, and emissions and parking regimes shape which vehicle can get to a job and where it can stand. Both add cost and both are worth pricing rather than absorbing.
Compliance considerations for roofers
Working at Height Regulations 2005 — the regulation that sits behind almost every roofing job, and the first thing an underwriter asks about.
Hot-works permit and fire-watch conditions from insurers wherever torch-on, bitumen boilers, hot-air welding or lead burning are used.
Fragile-surface duties: rooflights, fibre-cement sheets and old glazing are a leading cause of fatal falls in roofing, and cover terms usually reflect how you manage them.
CDM 2015 duties on larger contracts — on many domestic re-roofs you are the only contractor, which puts more of the duty on you than people expect.
Competent-person scheme evidence (NFRC, CompetentRoofer and similar) where you hold it, and Building Regulations notification for a re-roof that changes more than a limited proportion of the covering.
Scaffolding: a design or a compliant standard configuration, handover documentation, and a licence from the highway authority wherever it stands on a pavement or road.
What can go wrong
Material falls from a roof or scaffold onto a busy pavement and injures a passer-by — public liability responds, subject to the wording.
Torch-on work at a parapet or party wall ignites timber in the neighbouring property — hot-works permit and fire-watch conditions bite.
Rain enters through an opened flat roof and damages the occupied flat directly beneath.
A relined valley gutter overflows again in heavy rain and the client says the design, not the debris, was at fault — professional indemnity territory.
Scaffold erected without the borough’s licence is the subject of enforcement, and an injury claim becomes much harder to defend.
An operative falls while working at a parapet edge — employers’ liability responds, with RIDDOR reporting and regulator involvement likely.
Frequently asked questions
Why do valley gutters cause so many claims?
Because the failure is hidden and the water goes indoors. A central valley behind a parapet drains through a single outlet; block it or let the lining fail and the roof holds water instead of shedding it. Disputes then turn on whether the lining was inadequate or the gutter was never cleared, which is a specification and advice argument as much as a workmanship one.
Do I need a licence for scaffolding and skips?
For anything standing on the public highway, yes — that is a borough permission, and each borough runs its own process. It is a legal requirement rather than an insurance condition, but an unlicensed scaffold makes a public liability claim considerably harder to defend if someone is hurt.
How is hot work treated in a terrace?
Strictly, and rightly. Torch-on and lead burning at a party wall or parapet put heat next to a neighbour’s timber. Expect a hot-works permit and a fire-watch period as a policy condition, and expect insurers to ask whether you have moved to cold-applied systems for the highest-risk details.
What limit do London clients ask for?
It varies by client and by contract, and managing agents, boroughs and commercial clients often specify a minimum before letting you on site. Check the requirement at tender rather than after you have won the work — limits are subject to underwriter assessment and take time to arrange.
Am I covered for damage to the flat below an open roof?
Damage to third-party property arising from your work is what public liability is for, subject to the terms, and your own work in progress is what contract works covers. Both matter on a strip-and-recover above occupied rooms, and the temporary protection you use is what underwriters will ask about.
Do I need employers’ liability for labour-only sub-contractors?
Yes — it is legally required if you employ anyone, and labour-only sub-contractors working under your direction count.
