Seething Wells Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Seething Wells and the rest of Greater London. Surveys run seven days a week.
- Leaks through a flat roof with no obvious cause
- Leaks that return after repairs
- Damage from equipment installers
What we look for on each type of roof
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We’ll tell you if yours is not suitable.
How electronic leak detection works in Seething Wells
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. Common reasons to book are leaks showing away from the breach and leaks through a covered membrane, across liquid-applied waterproofing, single-ply roofs and green roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Seething Wells, 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.
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.

Seething Wells questions
Can parking be tricky for a visit in Seething Wells?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Can you look at the flat roof of a hotel or office near Seething Wells?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you’ll get a quote based on the building, and roof access is agreed with you ahead of the visit.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
How many surveys have you done?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or use the contact form.
Can you survey in bad weather?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather is not suitable.
Leave it or get it looked at?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. London’s older roofs often have bitumen felt underlay or none 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.
To find out what your survey will cost, phone 07833 053749 or email us and let us know about the roof. The price is agreed before a date is set.

What affects the cost of electronic leak detection
To price your survey, we check:
- How complicated the roof is, with its valleys, chimneys and parapets
- The size of the roof
- Commercial roofs and larger buildings
- How tall the building is and how easy the roof is to see
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the exact price before you book.
Helping us price your survey
Before you get in touch, it’s useful to have:
- Any stains, drips or damp patches you’ve seen indoors
- The type of building and roof, such as pitched or flat
- Whether there’s a loft hatch, a shared roof or tricky access
- Pictures from the garden or a window, if you have them
We survey roofs on weekdays, Saturdays and Sundays. To arrange a day that suits you, ring 07833 053749 or drop us an email.
Electronic leak detection in Seething Wells: local notes
Seething Wells has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. The wider area around Seething Wells has a long history of building, with Hampton Court Palace about 1.3 miles north-west. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you run a hotel or guest house in or near Seething Wells, a roof problem can mean rooms out of use. If you own a rental within reach of Surbiton station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For site and facilities teams at buildings such as Maple Infants' School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. In Seething Wells, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
- Leave side gates unlocked

Advice
Surveys for landlords and agents in Seething Wells
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or email us with the addresses.
Letting agents can arrange access with tenants. Surveys run on weekdays, Saturdays and Sundays, which can make access easier.
Checking the roof from ground level
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.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
