Electronic Leak Detection in West Tisted
Electronic leak detection to pinpoint holes in flat roof membranes for West Tisted, from an experienced roof surveyor. You get a clear written report with photographs.
- Water coming in under a flat roof
- Stains far from any visible defect
- Holes around roof penetrations
DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Electronic leak detection in West Tisted
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Tell us about your roof to find out more. Typical surveys look at repairs that haven’t stopped the leak and leaks through a covered membrane, across liquid-applied waterproofing, green roofs and commercial flat roofs.
Some older homes in villages like West Tisted are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What we do, step by step
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It typically takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. For a village or hamlet like West Tisted, the journey is planned beforehand: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Check the loft hatch can be reached
- Make a note of anything you’d like us to look at
- Buyers: confirm access with the estate agent or seller
How to book
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you are ready.
Advice
Different roofs, different checks
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. We test where the roof suits it.
Flat roofs in West Tisted
Some Hampshire villages 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 on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Hinton Ampner House, about 3.6 miles west, show how far back building in the area around West Tisted goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
West Tisted is about 7 miles north-west of Petersfield, in Hampshire. Whether the building in West Tisted is a house, a flat or a commercial unit, the roof can be surveyed.

Common roof problems in West Tisted
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
Typical things we’re asked to look at include:
- Punctures from foot traffic or tools
- Leaks at pipes, outlets or fixings
- Gaps at membrane joints
- Breaches hidden under paving or planting
Take an older house close to Church of St Mary Magdalene: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Before booking any roof surveyor
- Which parts of the roof they’ll actually see
- Whether the loft is part of the inspection
- What happens after the report arrives
- Whether any drone flown is registered with the CAA
Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Get leaks traced quickly
- Keep a note of leaks after rain
- Make sure trades protect the waterproofing
- Let us know about the membrane and build-up if you know it
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
When you need someone else
It’s a careful look at the flat roof membrane, not the whole story. Its limits include:
- Moisture spread under the membrane
- Parts of the roof covered by fixed equipment
- Build-ups without a suitable layer below

Questions from West Tisted
Do you cover West Tisted?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is West Tisted within the area you cover?
Yes. West Tisted is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Does ELD include fixing the breach?
No, our part is finding the breaches. The report gives your roofer the locations.
