If the build-up rules out ELD, we will say so.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
About our electronic leak detection in Tooting
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. We are frequently asked to look into waterproofing to test before it’s covered and leaks that return after repairs, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Tooting, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.

Signs you need electronic leak detection in Tooting
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Look out for signs like these:
- Punctures from foot traffic or tools
- Waterproofing to test before it is covered
- Breaches around outlets and penetrations
- Patched roofs that still leak
Tooting is in London, so parking needs planning: let us know about parking bays, permits or a driveway when booking, as a space near the door can’t be promised.
What to check before booking
- What the survey will not cover
- Whether VAT is in the quoted price
- What the report includes, and whether it has photos
- Are they insured for the work?
Surveys for landlords and agents in Tooting
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
Questions from Tooting
Can parking be tricky for a visit in Tooting?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Is my home in Tooting listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
How long will testing take?
Testing normally takes a length of time set by the roof’s area and construction, which we’ll explain when we quote.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
How fast do I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, tell us when you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What affects the price in Tooting
A few things affect what a survey costs:
- Chimneys, valleys, parapets and other details
- Whether thermal imaging or a drone is needed
- How tall the building is and how easy the roof is to see
- The size of the roof
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
What helps most when you contact us:
- The property’s address and postcode
- Dates you are working to, such as exchange
- Pictures from the garden or a window, if you have them
- What made you get in touch
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or use the contact form.
How the survey works
After the inspection, everything we found is written up as a written report with photographs, sent to you by email. On timing, it normally takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. For a visit in Tooting, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it’s safe.
- You tell us about the roof and where water is showing.
- 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 photographs shows where each breach is.
Getting ready for the survey
- Leave a clear route to the loft
- Let us know about parking before the day
- Find any records of previous roof work
Booking a survey
Getting a price is simple: just ring 07833 053749 or drop us an email, let us know about the property and we’ll suggest the right survey. The price is agreed up front.

Flat roofs in Tooting
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Southside House, about 3 miles west, is one of the historic houses in the wider area around Tooting. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
For businesses in and around places such as Southside Wandsworth, outlets and upstands on commercial flat roofs are the places to check before trouble starts. The streets around a church such as St Augustine are frequently among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems typically start.
