Electronic Leak Detection in Daw's End
Electronic leak detection in Daw's End from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and South East England.
- Damp inside with no sign on the roof
- Holes left by work on the roof
- Waterproofing to test before it’s covered
For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Let us know about it as you book and we will plan the survey around it.
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.
Electronic leak detection in Daw's End
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We’ll tell you if the roof cannot be tested. We survey flat roof membranes, liquid-applied waterproofing and single-ply roofs, and people most frequently book us about breaches around outlets and penetrations and leaks through a flat roof with no obvious cause.
In a small place like Daw's End, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

How it works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely, from the ground, from windows, in the roof space and by drone where it applies. Most surveys take a length of time set by the size of the roof and how it’s built, which we set out in the quote. Rural addresses near Daw's End can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Check we can get to the back of the property
- Clear the way to the loft hatch
- Find any records of previous roof work

What electronic leak detection doesn’t cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Sections we cannot safely access
- Moisture spread under the membrane
- Leaks from plumbing or windows

Daw's End: your questions answered
Do you cover Daw's End?
We do. The survey and report are the same in Daw's End as anywhere else, and visits run on weekdays and weekends.
Is my home in Daw's End listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s 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.
Do you climb onto every roof?
Only if it is safe. We look at everything that can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
How is ELD priced?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or use the contact form for a quote.
Do you need to get into the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps.
Is this a RICS 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.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.

Electronic leak detection in Daw's End: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. England has around 10,000 conservation areas and about 500,000 listed buildings. If your 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, so check with the council.
For site and facilities teams at buildings such as Anstey First School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. For an older house near a landmark such as Church of St George, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

Practical tips
Nothing here needs a ladder. Our suggestions:
- Check new waterproofing before handover
- Do not keep patching the same spot
- Note where leaks show inside and when
- Ask contractors to protect the membrane
Questions about the results are welcome. We’ll explain what was found and what it means.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
What a survey costs
The price reflects the time and kit the roof needs. That comes down to:
- Whether it’s a home or a commercial building
- How complicated the roof is, with its valleys, chimneys and parapets
- How big the roof is
- Extensions, dormers and garages with roofs of their own
