Electronic leak detection in Southfields, Greater London

- Damp inside with no sign on the roof
How we price electronic leak detection
A few things affect what a survey costs:
- If the survey needs thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- Whether it’s a home or a commercial building
- How big the roof is
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 safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
To price your survey accurately, we will ask about:
- Any stains, drips or damp patches you’ve seen indoors
- Your timetable, like an exchange date
- What kind of property and roof it is
- Your postcode, so we can check access and travel
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or email us.
Electronic leak detection in Southfields
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof can’t be tested. Common reasons to book are leaks showing away from the breach and breaches hidden under paving or planting, on commercial flat roofs, single-ply roofs and green roofs.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Southfields, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
The report is written in plain words, so you do not need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What else we do in Southfields
Electronic leak detection in Southfields: local notes
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses like Fulham Palace, about 1.9 miles north-west, show how far back building in the area around Southfields goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If your home is one of the older ones in the streets near St John the Divine, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Parking in Southfields, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised. If you look after a building such as Floreat Wandsworth Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
Southfields is about 2 miles north-east of Wimbledon, in Greater London.

Different roofs, different checks
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. ELD can help locate them on suitable roofs.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
What you can safely check yourself
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
When you need someone else
No survey can tell you everything, and it is better to know them up front. Bear these in mind:
- Some conductive membranes
- Fixing the holes we find
- Areas we cannot reach or that can’t be tested
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we’ll tell you before booking. What a survey covers and does not.
What this survey covers
- Roof terraces and balconies
- Green roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Tell us about it as you book and we will plan the survey around it.
Questions from Southfields
Do you carry out roof surveys in Southfields?
Yes. We cover the whole of London and South East England, and Southfields is part of that. You can call 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Southfields?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
What’s in the report?
It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
How much time does ELD need?
It normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Does the report include photographs?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
How do I arrange electronic leak detection in Southfields?
The quickest way is to ring 07833 053749 or use the contact form. Let us know the address and a little about the roof. Surveys run on any day of the week.
Will you go up on the roof?
Only where it is safe to do so. We inspect what can safely be seen: from ground level, from windows, from inside the loft space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
How it works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. In Southfields, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Gather any invoices or paperwork from past roof work
- Agree roof access with the managing agent if it is shared
- If you’re buying, let the agent know when we’re coming
Getting a price
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or send us an email.
