Sacombe Green Electronic Leak Detection
Electronic leak detection across Sacombe Green, with over 20 years’ experience behind it. Every survey ends with a written report and photos.
- Leaking laps in the waterproofing
- Holes left by work on the roof
- Leaks through a covered membrane
DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Electronic leak detection in Sacombe Green: what you get
There are different ELD methods. Low-voltage methods typically need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We’ll say if your roof doesn’t suit either method at the outset. If you’ve noticed stains far from any visible defect and leaks at pipes, outlets or fixings, a survey will tell you what’s going on, on green roofs, roof terraces and balconies and commercial flat roofs alike.
In a village or hamlet like Sacombe Green, flat roofs are typically 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. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
After the visit, you get a report with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Sacombe Green, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Make a note of anything you’d like us to look at
- If the roof is shared, arrange access with whoever manages the building
Getting a price
We confirm the price for the job before booking, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or drop us an email.
Advice
Common roof problems in Sacombe Green
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
We are frequently asked to look at:
- Holes left by work on the roof
- Leaks that return after repairs
- Leaks under green or ballasted roofs
- Waterproofing to test before it is covered
If you look after a building like Ralph Sadleir Middle School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- How they plan to inspect the roof safely
- Their drone registration, if they fly one
- Whether they hold professional indemnity and public liability insurance
- Their report turnaround times
Electronic leak detection around Sacombe Green
With Aston Bury about 4.4 miles west, Sacombe Green sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as 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. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you own a rental within reach of Watton-At-Stone station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For an older house near a landmark like Church of St Katherine, the joins between later flat roofs and the old walls are where problems normally start.

FAQs for Sacombe Green
Do you cover Sacombe Green?
Yes, Sacombe Green is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Will you come out to Sacombe Green?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where it applies.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
How long will testing take?
It usually takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Does ELD include fixing the breach?
No, our part is finding the breaches. The report gives your roofer the locations.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Prices for electronic leak detection in Sacombe Green
What a survey costs depends on the time and equipment it needs. The main factors are:
- How big the roof is
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
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 it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Use boards when working on the roof
- Act on new leaks promptly
- Note where leaks show inside and when
- Stay off the flat roof unless needed
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Make sure contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
