How electronic leak detection works in Clapham
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We’re frequently asked to look into a flat roof leak that can’t be traced and leaks under green or ballasted roofs, across single-ply roofs, green roofs and flat roof membranes.
Some older homes in villages like Clapham are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Flat and commercial roofs around Clapham
The coast is about 4 miles or less from Clapham, so there’s more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If yours is one of the older homes in the streets near The Parish Church of St Mary, the flat roofs on later extensions tend to wear out long before the main roof. Ecclesden Manor, about 1.5 miles south-west, is one of the historic houses in the wider area around Clapham. Older houses nearby often have flat roofs added much later, built to very different standards from the main roof. Landlords with a home close to Goring-By-Sea station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What happens if roof problems are left?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. Where a roof is exposed, as many are in small places like Clapham, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Clapham questions
Is my home in Clapham listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Clapham within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Do you use drones?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Different roofs, different checks
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We’ll say if the test will not work.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What else we do in Clapham
The survey, step by step
Every roof is different, but as a rough guide the survey takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. You are welcome to ask questions while we are there. In a small place like Clapham, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Before we arrive
- If you are buying, check with the agent that we can get in
- Keep pets in another room
- Dig out any old roof reports or invoices
Arrange a survey
