Electronic leak detection in Sand Hill
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. We survey single-ply roofs, commercial flat roofs and green roofs, and people most frequently book us about gaps at membrane joints and stains far from any visible defect.
Older buildings in small places like Sand Hill may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What we cannot see
We only report what can be seen safely on the day, so some things are outside what a survey can do:
- The extent of water in the insulation
- Repairing the breaches (that is for your roofer)
- Build-ups without a suitable layer below
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey before booking. What a survey covers and doesn’t.
What we look at
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
- Green roofs

Tips that help
Nothing here needs a ladder. A few suggestions:
- Act on new leaks promptly
- Keep a note of leaks after rain
- Check new waterproofing before handover
- Find the breach before more patching
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Do you need electronic leak detection in Sand Hill?
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Typical things we are asked to look at include:
- Breaches hidden under paving or planting
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Stains far from any visible defect
For any home in Sand Hill, it’s the small, early fault that is cheapest to put right.

- Will the report include photos?
- Whether the roof space is looked at, where there is one
The survey, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a hamlet or village like Sand Hill, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Let us know about parking before the day
- Jot down any questions you want answered
- Move anything stored under the loft hatch
Getting a price
We confirm the price for your survey before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or drop us an email.

Different roofs, different checks
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That’s where a survey comes in.
Common questions in Sand Hill
Do you cover smaller places like Sand Hill?
We do. A small place gets exactly the same survey as a big one.
How do I find out if my home in Sand Hill is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing typically 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. Tell us which days suit you as you book.
Do you survey roofs on blocks of flats?
Yes, if the building owner or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Local flat roofs in Sand Hill
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. 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.
If you live in an older home near Parish Church of St Andrew, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
