Electronic leak detection in Alderholt
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. If you’ve noticed leaks under green or ballasted roofs and leaks through a flat roof with no obvious cause, we can find out what’s behind it, on commercial flat roofs, liquid-applied waterproofing and roof terraces and balconies alike.
Outbuildings, garden rooms and garages in places like Alderholt often have flat roofs of their own. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when booking and we will plan the visit with that in mind.

Local flat roofs in Alderholt
Some Hampshire villages still have thatched roofs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 4.5 miles north-east lies Breamore House, a reminder of how long the area around Alderholt has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building such as St James' Church of England First School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

The survey, step by step
Every roof is different, but as a rough guide the survey takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. If you have questions on the day, just ask. Being in a smaller place like Alderholt does not change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- For flats, check roof access has been agreed
Getting a price
A quick phone call is usually the easiest start: ring 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.

What we look for on each type of roof
Bituminous membranes
Bitumen roofs can frequently be tested electronically though the layers below matter.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
FAQs for Alderholt
Will you come out to Alderholt?
Yes, Alderholt is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Alderholt is listed?
Historic England’s list shows listed buildings, and the local council can tell you about 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.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
What do I do with the report?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How does ELD work?
A sound membrane blocks the test current, but a hole lets it through. That is how we locate breaches you cannot see.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
Before and after the survey
From years of surveys, a few habits stand out as worth the effort:
- Act on new leaks promptly
- Limit access to the roof
- Do not keep patching the same spot
- Record dates and spots where water appears
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Do you need electronic leak detection in Alderholt?
Holes in a membrane frequently come from feet, tools or debris. Some are too small to see but water still finds them.
Problems we come across often include:
- Waterproofing to test before it’s covered
- Leaks through a flat roof with no obvious cause
- Breaches hidden under paving or planting
- Holes around roof penetrations
The streets around a church like Church of St James are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems usually start.
