Electronic leak detection for homes and businesses in Longmoor
There are different ELD methods. Low-voltage methods typically need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we will use. We’ll say if your roof does not suit either method at the outset. If you’ve noticed holes around roof penetrations and stains far from any visible defect, a survey will tell you what’s going on, on flat roof membranes, single-ply roofs and liquid-applied waterproofing alike.
Some older homes in villages like Longmoor are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

What else we do in Longmoor
What happens on the day
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and anything we can’t see is noted in the report. The survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Longmoor frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- If you’re buying, check with the agent that we can get in
- Point out any leaks or damp patches
- Keep pets out of the way during the survey

Advice
Signs you need electronic leak detection in Longmoor
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Most people get in touch when they’ve noticed one of these:
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
- Breaches hidden under paving or planting
- Leaks showing away from the breach
If you own a rental within reach of Liss station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- Their track record with similar roofs
- Whether you can ask questions once you have the report
- Their report turnaround times
- What the report includes, and whether it has photographs
Flat and commercial roofs around Longmoor
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. 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. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Take a building like Greatham Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Prices for electronic leak detection in Longmoor
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Extra roofs, like extensions, dormers or garages
- The use of thermal imaging or a drone
- The size of the roof
- The type of building, from a house to a block or an office
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Getting in touch
To price your survey accurately, we will ask about:
- What made you get in touch
- Whether there is a loft hatch, a shared roof or tricky access
- Any deadline, like an exchange date
- Any stains, drips or damp patches you’ve seen indoors
We survey roofs on any day of the week. To arrange a day that suits you, ring 07833 053749 or drop us an email.
Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Act on new leaks promptly
- Find the breach before more patching
- Keep outlets clear of debris
- Stay off the flat roof unless needed
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Act on leaks quickly. Water under a membrane can spread.
Longmoor: your questions answered
Do you cover smaller places like Longmoor?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
How do I find out if my home in Longmoor is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
Does ELD work under paving or planting?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we’ll check whether ELD will work.
