How electronic leak detection works in St George in the East
We carry out electronic leak detection on flat roofs in St George in the East and across London and South East England. A visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and people most frequently book us about patched roofs that still leak and breaches around outlets and penetrations.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in St George in the East, the roof above may belong to the building rather than one flat.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Note where leaks show inside and when
- Check new waterproofing before handover
- Clear flat roof outlets regularly
- Keep foot traffic on flat roofs to a minimum
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.

Flat and commercial roofs around St George in the East
Historic houses like Mansion House, about 1.2 miles west, show how far back building in the area around St George in the East goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in St George in the East is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For businesses in and around places such as Surrey Quays Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you look after a building such as St Paul's Whitechapel Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to St Peter's: the flat roofs on later extensions tend to wear out long before the main roof.

What you can safely check yourself
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.

- The extent of water in the insulation
- Build-ups without a suitable layer below
