How electronic leak detection works in Andover Down
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. Typical surveys look at water coming in under a flat roof and new roofs to check before paving or planting, across flat roof membranes, liquid-applied waterproofing and commercial flat roofs.
Older buildings in small places like Andover Down may be 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, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. In a small place like Andover Down, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.

Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Areas we cannot reach or that cannot be tested
- Water entering through details rather than the membrane
- Roofs whose membrane or build-up isn’t suitable
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey. What a survey covers and doesn’t.
Roof types and parts we check
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Roof terraces and balconies
What happens on the day
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Andover Down, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First, you let us know about the roof build-up and where water is showing.
- 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.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Mention any parking restrictions on your street
- Jot down any questions you want answered
- Show us where any leaks or stains appear

Common questions in Andover Down
Is Andover Down in the area you cover?
Yes, Andover Down is one of the places we work. Every survey there gets the same written report with photos.
Is my home in Andover Down listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
How do you choose the testing method?
The roof decides the method. We’ll explain why when we quote.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Do you take photos of the roof?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we will agree the details when booking.
Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Flat and commercial roofs around Andover Down
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. Some Hampshire villages still have thatched roofs. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you own a rental within reach of Andover station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Pilgrims' Cross CofE Aided Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Useful tips for Andover Down property owners
These tips come from what we see on roofs every week:
- Limit access to the roof
- Record dates and spots where water appears
- Do not let outlets block
- Have roof specifications to hand
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
