Clapham has Georgian houses around Old Town and the Common, then the Victorian terraces that fill everything between, and the mansion blocks along the Common's edges. A conservation area for much of it, and slate and lead almost throughout.

Clapham’s roofs
Clapham Old Town and the terraces around the Common are Georgian and early Victorian, many listed, roofed in slate behind parapets that conceal flat lead roofs and gutters. They need like for like repair with matched slate and properly formed lead, from a roofer who knows the hidden gutter is usually where the trouble lies.
Towards Clapham North and Stockwell, the streets are earlier Victorian terraces, many with London roofs: two slopes falling inwards to a central valley gutter behind a front parapet. They are hard to see and easy to neglect, and when the valley blocks, the top floor gets wet.
Around Abbeville Road and down to Clapham South, the terraces are later Victorian and Edwardian, roofed in Welsh slate with gables, bays, shared stacks and rear wings. Most streets now have rear dormers from loft conversions.
Along the Common and the main roads stand Victorian and Edwardian mansion flats with slate mansards, dormers, parapets and internal gutters. Their freeholders and managing agents need surveys and prices they can put to leaseholders, as much as they need the repairs themselves.
Behind most Clapham terraces there is a back addition with a low roof, and often a flat roofed kitchen extension beyond it. Leaks at the junction with the main wall, and failed felt on the flat roofs, are among the most common calls we get here.
Our yard is fifteen miles away; Clapham is on the London line, 0203 507 1501. Lambeth covers most of it, Wandsworth the western edge. With so much of Clapham listed or in conservation areas, the status of a house is checked before any change is suggested.
Along Clapham High Street and the parades off it, Victorian shops have flats above and flat roofed rear extensions behind. The front roofs hide behind parapets, the back ones are reached over other buildings, and a leak on the top floor flat can start in either. These are as much access jobs as roofing jobs.
Towards Brixton Hill, Clapham Park mixes large Victorian villas, many converted, with inter war and post war estates, parts of which have been rebuilt in recent years. The villas have big slate roofs and lead; the estates have flat roofs and long runs of gutter. It is one of the most varied corners of SW4.
What we are called to in Clapham
What we do in Clapham

Clapham has some of the oldest and most hidden roofs we work on. We follow a leak to the gutter, flat or flashing that has actually failed, and put that right in matching materials.

Box gutters, lead flats, central valleys and flashings. Clapham's roofs depend on lead, which we shape on site in the right code, laid to fall with proper joints.

Almost every Clapham roof is Welsh slate, much of it original. Sound slate is kept, broken slates are replaced with reclaimed ones that match, and whole slopes are relaid on new battens only when the fixings have gone.

Roof repairs in Clapham
Clapham's period roofs fail in particular places. These six are the ones we see most.

Likely cause
Behind a Georgian or Victorian parapet there is usually a box gutter or a central valley. When it blocks or its lead splits, water comes straight into the top floor. We clear it, reline it in lead and check the outlet.
Usually the job is
Leadwork in Clapham
Likely cause
With a London roof both slopes drain inwards to a gutter running front to back down the middle of the house. If it splits, or silt stops it draining, the stain appears in the middle of the top floor ceiling. The valley is relined in new lead and the outlet at the back is cleared.

Roof Leak Repairs in Clapham
Likely cause
Open pots on a stack that is no longer used let rain, leaves and nesting birds straight down the flue, and the breast below ends up damp. We fit cowls or cap the pots so the flue still breathes, and check the flaunching while we are up there.
Usually the job is
Chimney Repairs in Clapham
Likely cause
Nearly always the back addition: either its roof covering has worn out or the lead along the main wall has come away. We fix whichever has failed, and point the new lead into a cleaned out joint.

Roof Repairs in Clapham
Likely cause
Kitchen extensions here often carry felt that has been patched more than once and now holds water. The patches come off, the old felt is stripped, any soft decking is renewed and a GRP or felt roof goes on with a proper fall.
Usually the job is
Flat Roofing in Clapham
Likely cause
Clapham's original slates are mostly still good; it is the nails, well over a century old, that give way. Odd slates are held with tingles. When slipping is general, the slope is stripped, the battens renewed and the slate relaid.

Slate Roofing in ClaphamHow it works
Call the London line on 0203 507 1501 or send a picture. For a flat in a mansion block, pass on the managing agent's details so access can be agreed early.
Inspection happens on the roof, including the box gutters and central valleys you cannot see from the street, with photographs of each defect.
You get a written price, line by line. Listed and conservation area work is described as like for like so it can be checked.
The work is carried out under a council scaffold licence in matching materials, with pictures before and after.

Clapham questions
Something else about a Clapham roof? Phone 0203 507 1501.
Yes. Like for like repair in matched reclaimed slate and new lead, which is what the conservation officer wants and what these roofs need.
Yes, and Clapham Common, Old Town, Abbeville Village, Stockwell and down to Balham.
Yes. Before exchange we can get up on the roof, photograph each slope and detail, and give you a written view of what it will need and when.
Two slopes falling inwards to a gutter running down the middle, hidden behind a front parapet. It is common on the earlier terraces round Clapham North, and that central gutter is what needs looking after.
Yes. Freeholders and managing agents get a survey with photographs and a written price they can circulate to leaseholders.
On terraced streets the scaffold stands on the pavement with a licence from Lambeth, or Wandsworth on the western side, and parking is planned around it. We apply ahead of the start.
Yes. Rear gutters on Clapham terraces are often old and fixed to tired fascia boards. We replace the boards where needed and fit new guttering that falls to the downpipe.
Yes. We work with the owner or the managing agent, plan access over the back of the building, and repair or renew the flat roof with a proper fall to its outlet.
Yes, for owners, landlords and managing agents. Flat roofs, outlets and long gutter runs on the estate blocks are surveyed, photographed and priced in writing.
