Electronic Leak Detection in Perham Down
Electronic leak detection across Perham Down, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.
- A flat roof leak that can’t be traced
- Holes left by work on the roof
- Leaks that return after repairs
Electronic leak detection in Perham Down: what you get
Our ELD report shows where each breach was found, with photographs. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We survey flat roof membranes, liquid-applied waterproofing and roof terraces and balconies, and the problems we’re asked to look at most are stains far from any visible defect and patched roofs that still leak.
Somewhere as small as Perham Down, 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 in advance. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

When you need someone else
A survey is a close look at the flat roof membrane, but it cannot do everything. The main limits are:
- Leaks from plumbing or windows
- Build-ups without a suitable layer below
- The extent of water in the insulation
If in doubt, ring 07833 053749 or email us and we’ll suggest the right survey before you book. The full list of what we check.

Perham Down: your questions answered
Is Perham Down in the area you cover?
Yes. We work right across London and the South East, and Perham Down is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
Is Perham Down within the area you cover?
Yes, Perham Down is covered. Our area covers London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That is how we locate breaches you can’t see.
How do I book a survey in Perham Down?
It’s easiest to ring 07833 053749 or email us. Let us know the address and a little about the roof. We survey on any day of the week.
How long will testing take?
It normally takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting.
What if it rains on the day?
Light rain is normally fine; heavy rain and wind are different. High wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. Older and listed buildings around Perham Down may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Consider ELD before paving or planting goes on
- Use boards when working on the roof
- Avoid repeated repairs without finding the cause
- Get leaks traced quickly
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

What else we do in Perham Down
Do you need electronic leak detection in Perham Down?
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
A survey makes sense if you’ve noticed:
- Water coming in under a flat roof
- Repairs that haven’t stopped the leak
- Failed seams and laps
- Leaks through a covered membrane
Take a building like The Wellington Academy: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- Their drone registration, if they fly one
- Is there a chance to talk the report through?
- What insurance they carry
- How much experience they have with roofs like yours
What you can safely check yourself
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. Don’t go up yourself.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where applicable.
Electronic leak detection around Perham Down
Some Hampshire villages still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
The streets around a church like Church of St James are often among the oldest in a place, and if you own one of the older houses nearby, the joins between later flat roofs and the old walls are where problems normally start. Landlords with a home close to Grateley station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

The survey, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. It typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Around Perham Down, older homes can have small or awkward roof spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Getting ready for the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Keep pets out of the way during the survey
- Dig out any old roof reports or invoices
