About our electronic leak detection in Brasted
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. We survey commercial flat roofs, single-ply roofs and green roofs, and people most often book us about failed seams and laps and leaks under green or ballasted 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 Brasted, 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.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Questions from Brasted
Do you carry out roof surveys in Brasted?
We do. Every survey there gets the same written report with photos.
Does a conservation area affect roof work in Brasted?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is 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.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How do I arrange electronic leak detection in Brasted?
To arrange a survey, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How many surveys have you done?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.

What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- Height and safe access
- How big the roof is
- Whether thermal imaging or a drone is needed
- Extensions, dormers and garages with roofs of their own
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.
Helping us price your survey
A few details help us point you to the right survey and price. When you get in touch, it’s useful to mention:
- The property’s address and postcode
- When you need the report by
- Pictures of the roof from a safe spot, if you have them
- Any marks or damp showing indoors
To book a survey, ring 07833 053749 or send us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
For landlords and managing agents
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or send us an email with the addresses.
Letting agents often book on a landlord’s behalf. We agree a time with the tenant beforehand.
What we look for on each type of roof
Bituminous membranes
Bitumen roofs can often be tested electronically, depending on what’s below.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Electronic leak detection in Brasted: local notes
About 1.5 miles south-west lies Quebec House, a reminder of how long the area around Brasted has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Brasted is in London, so parking needs planning: tell us about permits, visitor bays or off-street space as you book. Landlords with a home close to Dunton Green station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Brasted is about 3 miles west of Sevenoaks, in Greater London. Whether the building in Brasted is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Our area takes in places right across Greater London, large and small. We also survey roofs in Crawley.

Common roof problems in Brasted
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
These are some of the problems a survey can pick up:
- Leaking laps in the waterproofing
- New membranes needing a check before handover
- A flat roof leak that can’t be traced
- Leaks showing away from the breach
Take a building like Combe Bank School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Questions to ask before booking
- What happens after the report arrives
- Whether the price includes VAT
- How soon the report will arrive
- Their insurance cover
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In a London area like Brasted, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Check we can get to the back of the property
- For flats, make sure roof access has been agreed
- Make a note of anything you’d like us to look at
How to book
Photos help, if you have them. Pictures from the ground or a window are fine. To get started, ring 07833 053749 or email us.

Why it is worth a survey now in Brasted
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
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.
