Wandsworth is the Victorian terrace at scale: the streets around the common, Southfields, the grid down towards the river. Slate roofs, shared chimneys, back additions and butterfly roofs, and a century of weather on all of it.

Wandsworth’s roofs
Beside Wandsworth Common, the parallel roads known as the Toast Rack are lined with large Edwardian and late Victorian houses, many under slate with clay ridges, deep bays and big stacks. Their roofs are generous, with dormers, gables and back additions, and the lead in their valleys and flashings is now well past its first century.
The Southfields Grid is a close pattern of Edwardian terraces built in the 1900s, roof after roof alike: slate or clay at the front, a back addition behind, a stack on each party wall. Because they are alike, the faults are too, and most of them are at the back, where the rear wing joins the house.
Around the old town centre, earlier Victorian terraces sit behind front parapets, some with a valley gutter running between two slopes, and the high street has flats over shops. That hidden gutter is easy to overlook until a blockage sends water through the top floor ceiling.
Along the Thames and the mouth of the Wandle, old industrial buildings have been turned into flats and new blocks have gone up, with flat roofs, membranes, roof terraces and parapets. Work there is planned with managing agents, and most problems are at outlets, upstands and joints rather than in the open roof.
Across the borough, terraces carry two storey rear wings with low roofs, some of them butterfly roofs that drain to a channel down the middle. That channel and the lead where the wing meets the house are the two places a Wandsworth terrace most often lets in water.
We are fourteen miles away and cover Wandsworth from the London line, 0203 507 1501. The council licenses scaffold on the pavement, and parking suspensions are often needed as well. Large parts of the borough are conservation areas, and repairs there match what is already on the roof.
Up West Hill and towards Putney, large Victorian houses, many now flats, sit on bigger plots with big roofs: several stacks, valleys, dormers and lead flats. Converted houses mean shared roofs and several owners to agree the work, and the roofs are big enough that a proper survey is the first step.
Facing Wandsworth Common, the shops and restaurants along Bellevue Road sit in Victorian parades with flats above and small extensions behind. Their front roofs are hidden by parapets and their rear roofs are crowded together, so a drip into an upstairs flat can begin a few metres from where it shows. Access through the back is usually the first thing to plan.
What we are called to in Wandsworth
What we do in Wandsworth

On most Wandsworth terraces the fault is one detail: a cracked slate, a split valley, a lifted flashing. That is what we find and fix, with photographs to prove it.

Butterfly valleys, rear wing flashings, bay tops and parapet gutters. New lead is bossed on the roof to the right weight, in short pieces that can move with the seasons.

SW18 is mostly Welsh slate. Single slates are replaced with matching reclaimed ones; a slope with failed fixings throughout is stripped, re-battened and relaid.

Roof repairs in Wandsworth
Six faults that account for most of our Wandsworth call outs. Find the one that matches yours.

Likely cause
On a terrace that usually points to the rear wing. Either the flashing along the house wall has let go, or the channel in the middle of a butterfly roof has split. New lead sorts both.
Usually the job is
Leadwork in Wandsworth
Likely cause
Earlier terraces in Wandsworth Town hide a valley gutter behind the front parapet. Moss and grit build up, water stands, and it gets through any weak joint. We clean it out and put in a new lead lining.
Usually the job is
Roof Leak Repairs in Wandsworth
Likely cause
High winds lift slates whose nails have rusted, and once one goes, those around it follow. We make the roof weathertight, refix or replace the slates, and photograph everything, which helps with an insurance claim.
Usually the job is
Storm Damage Repairs in Wandsworth
Likely cause
Wandsworth chimneys usually straddle the party wall, so the leak can show next door as easily as in your house. Worn joints, a cracked cap or loose lead are the usual causes. One written price lets the two owners share the cost.
Usually the job is
Chimney Repairs in Wandsworth
Likely cause
Felt dormer tops from the loft conversion boom are now cracking, and the side lead often pulls back from the slates. We put a GRP top on and renew the side lead so the dormer stays dry.
Usually the job is
Flat Roofing in Wandsworth
Likely cause
On larger flat roofs, water that will not drain is usually a blocked outlet or a sagging deck. Left, it gets in at the upstands. We clear the outlets, check the falls and repair or renew the covering.

Flat Roofing in WandsworthHow it works
Ring 0203 507 1501, or send a picture from the pavement or garden, and if you live in a flat, let us know who manages the block.
We look from the roof and the loft, rear wings and parapet gutters included, and take photographs of every fault.
The price comes in writing, item by item, with any pavement licence or parking suspension written into it.
Work is done tidily on a close street, with photo updates, and the area is cleared before the scaffold is struck.
