Hill End Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Hill End, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Punctures from foot traffic or tools
- Leaking laps in the waterproofing
- Stains far from any visible defect
The survey, step by step
We look at the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older roofs in small places like Hill End can have low, tight loft spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Leave a clear route to the loft
- Have any paperwork from past roof work to hand
- Jot down any questions you want answered
Booking a survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, call 07833 053749 or send us an email.
Advice
Electronic leak detection for homes and businesses in Hill End
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We will say if your roof does not suit either method before any testing starts. If you’re worried about leaks through a flat roof with no obvious cause and failed seams and laps, a survey will tell you what’s going on.
Some older homes in villages like Hill End are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what isn’t.

Practical tips
These tips come from what we see on roofs every week, before and after a survey:
- Check new waterproofing before handover
- Act on new leaks promptly
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Act on leaks quickly. Water under a membrane can spread.

Electronic leak detection in Hill End: local notes
About 4.1 miles south-east lies Ickenham Hall, a reminder of how long the area around Hill End has been built on. 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 any change of roofing material on a listed home needs checking with the council first. Some villages in Buckinghamshire still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Harefield Baptist Church, the joins between later flat roofs and the old walls are where problems usually start. Landlords with a home close to Rickmansworth station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Do you need electronic leak detection in Hill End?
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in long before anyone notices.
It is worth booking a survey if you’ve seen:
- Punctures from foot traffic or tools
- Leaks showing away from the breach
- Patched roofs that still leak
- New roofs to check before paving or planting
Anyone responsible for a site like Harefield Infant School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Is Hill End in the area you cover?
We do. The survey and report are the same in Hill End as anywhere else, and visits run on weekdays and weekends.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
