Electronic leak detection in Putney Vale, Greater London
Electronic leak detection to pinpoint holes in flat roof membranes in Putney Vale, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Breaches around outlets and penetrations
- New roofs to check before paving or planting
- Leaks through a flat roof with no obvious cause
Do you need electronic leak detection in Putney Vale?
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
We’re often asked to look at:
- Failed seams and laps
- Breaches around outlets and penetrations
- Leaks that return after repairs
- New membranes needing a check before handover
If you own a rental within reach of Raynes Park station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- Whether VAT is added on top
- Whether the roof space is looked at, where there is one
- Which limits apply to the survey
- What follow-up you get after the report
Electronic leak detection in Putney Vale
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that can’t give results. We survey liquid-applied waterproofing, green roofs and commercial flat roofs, and the problems we’re asked to look at most are gaps at membrane joints and new roofs to check before paving or planting.
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 Putney Vale, 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.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Why act early in Putney Vale
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. Any roof job in Putney Vale means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
The cost of a survey depends on the roof: its size, its height, how many sections it has 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.

Questions from Putney Vale
Is Putney Vale in the area you cover?
We do. The survey and report are the same in Putney Vale as anywhere else.
Will parking be an issue for a roof survey in Putney Vale?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How do I arrange electronic leak detection in Putney Vale?
Simply phone 07833 053749 or send us an email. We will ask a few questions, confirm the price and agree a date.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or use the contact form.
Flat roofs in Putney Vale
About 1.5 miles south-east lies Southside House, a reminder of how long the area around Putney Vale has been built on. On older houses around here, roofs frequently 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. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark such as St John the Baptist, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as Hall School Wimbledon, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. For a visit in Putney Vale, 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 is safe.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Gather any invoices or paperwork from past roof work
- For flats, check roof access has been agreed
- Check the loft hatch can be reached
Book a survey
Photos help, if you have them. Take them safely from the ground or a window. To get started, phone 07833 053749 or email us.

Tips from our surveys
You don’t need to be a roofer to help. What helps most:
- Clear flat roof outlets regularly
- Avoid repeated repairs without finding the cause
- Keep foot traffic on flat roofs to a minimum
- Make sure trades protect the waterproofing
Questions about the results are welcome. We can talk you through the findings.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
