Roofers in Clapham

Roof repairs, re-roofing, valley gutters and leadwork on Clapham’s Georgian, Victorian and Edwardian houses.

We repair and renew roofs across Clapham and SW4. The older houses near the Old Town and the Common often have roofs hidden behind parapet walls, drained by lead-lined valley and parapet gutters that are a common source of leaks. The Victorian and Edwardian terraces further out mostly have slate main roofs with flat roofs over the back additions. We work on all of them.

WHAT WE DO

Roofing in Clapham

Leaks on a parapet roof are often traced to the hidden gutters behind the parapet or in the central valley, where old lead splits or debris blocks the outlet. Water then runs into the walls and the top-floor ceilings. We clear, repair or re-line these gutters and repoint the parapets.

On pitched roofs we replace slipped and broken slates and tiles, re-roof in natural slate or clay tile when the covering has failed, and renew flashings around chimneys and party walls. We also replace felt flat roofs over back additions and dormers with GRP or EPDM.

IN CLAPHAM

Roofs on listed and period Clapham houses

On a listed house, like-for-like roof repairs generally do not need consent, but re-roofing in a different material, or changes to parapets, chimneys or rooflines, need listed building consent. In Clapham’s conservation areas we re-cover in natural slate or clay tile to match the street rather than switching to a cheaper material.

Pavement scaffolding needs a licence from the highway authority. For most Clapham streets that is Lambeth, and on the far side of the Common it is Wandsworth. On the main roads that Transport for London manages, the licence comes from TfL. We apply for it as part of the job.

GOOD TO KNOW

Roofing questions from Clapham homeowners

Why does my top-floor ceiling get damp when it rains hard?

On older Clapham houses it is often a blocked or split gutter behind the parapet, or a failed valley gutter between the roof slopes. We inspect it and repair or re-line the gutter.

Do I need permission to re-roof a listed house?

Like-for-like repairs generally do not. Changing the roofing material, or altering chimneys or parapets, needs listed building consent. We check before quoting.

Should I use natural slate or man-made slate?

On period houses, and especially in conservation areas, we recommend natural slate. It lasts far longer and matches the neighbouring roofs.

Can you replace the flat roof on my back addition?

Yes. We strip the old felt, repair the deck and lay a GRP or EPDM roof with new edge trims and flashings.

Who arranges the scaffold licence?

We do. Depending on the road, it comes from Lambeth, Wandsworth or Transport for London.
