Electronic leak detection in Great Gaddesden: what you get
We carry out electronic leak detection on flat roofs in Great Gaddesden and across London and South East England. Testing typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a report with photographs. If you’ve noticed holes around roof penetrations and new membranes needing a check before handover, we can find out what’s behind it, whatever the roof.
Somewhere as small as Great Gaddesden, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when booking.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Leave it or get it looked at?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
What you get with us
- 5,000+ roofs surveyed
- An independent view of the roof
- Covered by professional indemnity and public liability insurance
- Plain-English reports with photos
What happens on the day
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Older roofs in small places like Great Gaddesden can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Move anything stored under the loft hatch
- Check we can get to the back of the property
- Tell us where we can park nearby

Questions from Great Gaddesden
Will you come out to Great Gaddesden?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Is Great Gaddesden in the area you cover?
Yes, Great Gaddesden is one of the places we work. The survey and report are the same in Great Gaddesden as anywhere else.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Does this replace a RICS home survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Do you look in the roof space?
If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.

Tips that help
These tips come from what we see on roofs every week:
- Share any drawings of the roof
- Do not keep patching the same spot
- Keep outlets clear of debris
- Ask contractors to protect the membrane
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
Do not leave a flat roof leak running. Water under a membrane can spread.
Rented homes, blocks and businesses
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or use the contact form with the addresses.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant, which helps with budgets and planning.
Electronic leak detection in Great Gaddesden: local notes
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask.
For site and facilities teams at buildings such as Great Gaddesden Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. Take an older house close to Church of St John the Baptist: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
