Electronic leak detection for homes and businesses in Waterhales
ELD can be carried out in more than one way. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. If neither method suits your roof, we’ll tell you at the outset. We survey liquid-applied waterproofing, single-ply roofs and green roofs, and people most often book us about leaks at pipes, outlets or fixings and leaking laps in the waterproofing.
In a village or hamlet like Waterhales, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when booking.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Local flat roofs in Waterhales
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, alongside a good many post-war and newer estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Hare Hall, about 3.6 miles south, is one of the historic houses in the wider area around Waterhales. If you own one of the older houses, expect a mix of original materials and later repairs on the roof.
If you let a flat or house near Harold Wood station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Drapers' Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

When you need someone else
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- Leaks from walls, copings or rooflights
- Some conductive membranes
- How wet the insulation is
If in doubt, ring 07833 053749 or use the contact form and we’ll recommend the right survey before booking. What our survey covers.
Roof types and parts we check
- Single-ply roofs
- Liquid-applied waterproofing
- Green roofs
- Flat roof membranes
- Roof terraces and balconies
- Commercial flat roofs
Tips that help
Nothing here needs a ladder. A few suggestions:
- Check new waterproofing before handover
- Act on new leaks promptly
- Keep a note of leaks after rain
- Find the breach before more patching
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What we look for on each type of roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. We test where the roof suits it.
Why act early in Waterhales
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
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 survey before booking.

How it works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. Around Waterhales, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Keep pets inside or away from the areas we are looking at
- Leave a clear route to the loft
Booking a survey
Most bookings start with a short call: call 07833 053749 or send us an email, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.

Common roof problems in Waterhales
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Here are some of the things we see often:
- Leaks that return after repairs
- Breaches around outlets and penetrations
- Leaks showing away from the breach
- Water coming in under a flat roof
For an older house near a landmark such as Church of St Thomas, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
What to check before booking
- What they will not be able to tell you
- Whether VAT is added on top
- Whether any drone flown is registered with the CAA
- Their report turnaround times
Waterhales questions
Do you cover Waterhales?
Yes. Our area covers London and South East England, and Waterhales is part of that. You can phone 07833 053749 or drop us an email with the address and some details.
Will you come out to Waterhales?
Yes, Waterhales is on our map. Villages and rural addresses get the same survey as a town house.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What’s the best way to book?
To book, call 07833 053749 or drop us an email and tell us the address and what you’d like to know. We’ll confirm the price and find a day that suits.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
