Roofing in East London: repair, re-cover or replace

Roofing in East London means a lot of terraces and semis with shared roof lines, chimney stacks that sit on the party wall, and flat roofs on back additions and older extensions. A leak on one of those can start on your neighbour's side, at a tired lead flashing, or on a flat roof that was laid without a proper fall. We are BXC Developments, a building contractor based in Barking, and we find the cause before we quote for the cure.

Our London roofing photographs show the kind of work we mean: a new clay plain tile roof with a lead valley, clipped half-round ridge tiles running down towards the street, and a new felt flat roof finished neatly against the tiling and a roof window. Pitched roofs in clay, concrete or slate, and flat roofs in felt, GRP fibreglass or EPDM rubber, are all part of the job.

The rules. The Planning Portal says re-roofing will need Building Regulations approval in most situations, and that re-covering a roof should include improving its insulation. A change of covering, slate to tile for example, can also mean structural checks, because the weight on the rafters changes. In conservation areas it tightens further: Redbridge says its Article 4 directions can remove the right to replace roof coverings without permission. On the Becontree estate, the council's November 2025 report on its Design Code describes tiled pitched roofs and tall brick chimneys as part of the estate's character, so matching the original matters there.

The cost. As an outside benchmark, Less.co.uk's London cost page, updated 27 October 2026, puts a full re-roof on a terrace or semi at £7,000 to £14,500 and a typical roof repair at £180 to £820. MyJobQuote's London guide (9 September 2026) puts a new 40 square metre extension flat roof at £2,800 to £5,500. Neither says whether VAT is included, and neither is our price; ours comes in writing after a survey.

The access. On a terrace, scaffold often has to go up through a narrow side passage or over a front garden, and if it has to stand on the pavement the council's scaffold licence is part of our job. A shared chimney stack is a conversation with next door before anyone climbs. If you are converting the roof space, see our loft conversions in East London, because doing both under one scaffold costs less.

Roofing work we carry out across East London

Pitched re-roofs

Stripped to the rafters, timbers checked and replaced where they have gone, a breathable membrane and new battens, then re-covered in clay plain tile, concrete tile or slate to match the roof line. On a terrace, matching next door matters, both for how the street looks and, in a conservation area, for planning.

Repairs and leak tracing

Slipped or cracked tiles, ridge and hip tiles re-bedded or mechanically fixed, failed mortar fillets and flashings. We trace a leak back to where it actually starts, because a stain on a back bedroom ceiling can begin well uphill of it, at a valley, a chimney or on the neighbour's side of the roof.

Flat roofs

Back additions, dormers, extensions, garages and bays, in felt, GRP fibreglass or EPDM rubber, laid to a fall so water leaves the roof. Where the deck comes off, the insulation is upgraded as the Building Regulations expect, and the edge details, upstands and outlets are formed properly, because that is where flat roofs usually fail.

Lead work

Valleys, back gutters behind chimneys, step flashings, soakers, bay window roofs and the lead where a flat roof meets a pitched one. MyJobQuote's September 2026 London guide puts a 3 square metre lead bay roof at £725 to £1,000, which gives a sense of how much detail work costs once scaffold is up.

Chimney stacks

Repointing, re-flaunching the cement around the pots, new flashings, and capping disused flues with ventilation so they do not hold damp. On a terrace the stack is often shared with next door, so we talk to your neighbour before the scaffold goes up and tell you if the work touches the party wall.

Fascias, gutters and bigger jobs

Fascias, soffits and gutters replaced while the scaffold is already there, which costs far less than bringing it back later. Where you are having a loft conversion or an extension anyway, the roof work goes into the same programme under the same scaffold, and that is usually the cheapest way to buy it.

Roofing questions from East London homeowners

How much does a new roof cost in London?
As a benchmark, Less.co.uk's London page, updated 27 October 2026, puts a full re-roof at £7,000 to £14,500 for a terrace or semi and £11,500 to £23,500 for a detached house, with a typical repair at £180 to £820. It does not say whether VAT is included. The real figure depends on the covering, how much timber has gone, and the scaffold your street needs, so we survey and quote in writing.

Do I need building regulations approval for a new roof?
In most cases, yes. The Planning Portal says re-roofing will need Building Regulations approval in most situations, that re-covering a roof should include improving its insulation, and that a much heavier or lighter covering may need the structure checked or strengthened. Some small flat roof repairs do not need an application. We check with building control at quote stage, so the paperwork is in the price.

Do I need planning permission to re-roof my house?
Replacing a roof like for like normally does not need planning permission. In a conservation area with an Article 4 direction it can: Redbridge, for example, says its directions can remove the right to replace roof coverings without permission. A listed building needs listed building consent. If you live in a conservation area anywhere in Barking and Dagenham, Havering, Redbridge or Newham, we check the rules for your street before quoting.

My roof is joined to next door's. What happens when I re-roof?
On a terrace or semi, your roof meets your neighbour's at the party wall line, and the join has to be weathered properly so neither roof leaks into the other. We tell your neighbour before we start, protect their side, and finish the junction neatly. If the work touches a shared chimney stack or the party wall itself, we explain whether a Party Wall Act notice is needed.

How do I know if I need a repair or a whole new roof?
A few slipped tiles, one damp patch or a failed flashing are repairs. Widespread crumbling or sagging felt, battens rotting across a whole slope, tiles failing faster than they can be replaced, or a roof that sags between rafters point to a re-roof. We go up and look rather than quote from the pavement, and we photograph what we find so you can see it for yourself.

Felt, GRP or EPDM: which flat roof should I choose?
All three can work well when they are laid properly. Torch-on felt is the traditional choice and suits most budgets. GRP fibreglass gives a hard, seamless finish that suits dormers and roofs you will walk on for maintenance. EPDM rubber goes down in one sheet and copes well with movement. The fall, the edges and the outlets matter more than the material, and we price whichever suits your roof.

Can you fit a roof window into my existing roof?
Usually, yes. Under permitted development a rooflight can go into a house roof without planning permission as long as it does not stick out more than 150 millimetres from the roof slope and is no higher than the highest part of the roof. Side-facing windows must be obscure glazed. Conservation areas and Article 4 directions can change that, so we check your address first.

How do I check a roofer before I pay anything?
Ask for a written, itemised quote, a company name you can look up on Companies House, and a postal address. Be wary of a price given from the pavement, pressure to decide today, cash-only deals or a large deposit up front. BXC Developments Ltd has been on Companies House since July 2019, so you can check us the same way.
