Electronic Leak Detection in Blackmoor

- Leaks under green or ballasted roofs
- Punctures from foot traffic or tools
Electronic leak detection in Blackmoor: what you get
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a written report with photos of each breach found. If you are worried about gaps at membrane joints and holes around roof penetrations, a survey will tell you what’s going on.
Some older homes in villages like Blackmoor are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Every survey ends with a written report, with photos, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Roof by roof
Single-ply membranes
ELD often works on single-ply membranes but it depends on the product and layers.
Green and ballasted roofs
ELD is easier on a new roof before it’s covered.
What else we do in Blackmoor
What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Blackmoor, 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. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- 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.
Before the survey
- Check pets are kept safely away
- Let us know where we can park nearby
- Leave a clear route to the loft
Book a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or email us.

What affects the cost of electronic leak detection
We confirm the exact price before booking. This is what makes a difference:
- Extensions, dormers and garages with roofs of their own
- The use of thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- Chimneys, valleys, parapets and other details
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
What to tell us when you get in touch
You do not need to know any roofing terms. It’s enough to let us know:
- The property’s address and postcode
- Any deadline, such as an exchange date
- Why you want a survey: buying, a leak, a storm or new work
- Anything about access we should know
To book a survey, phone 07833 053749 or send us an email and let us know the address and what’s prompted the survey. You’ll know the price before anything is booked.
What electronic leak detection looks like in Blackmoor
Before planning roof work on an older home, find out whether it is listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. 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. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Liss station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like St Matthew's Church of England Aided Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Blackmoor is about 5 miles south-east of Alton, in Hampshire. Blackmoor gets the same service as everywhere else we work: a careful inspection, photos and a written report. Blackmoor is one of the places in Hampshire where we work for electronic leak detection. There is also a page for Guildford.
We work across GU33 for electronic leak detection and the streets around it. Streets in the area include Blackmoor Road and Sotherington Lane, all of which we cover. Other places close to Blackmoor include Woolmer (1 mile south-east), Greatham (1 mile south), Longmoor (2 miles south-east), Passfield (2 miles east) and Weavers Down (3 miles south-east). We also work in nearby towns like Basingstoke (15 miles north-west), Farnborough (15 miles north), Fleet (13 miles north), Horndean (14 miles south-west), Aldershot (12 miles north-east) and Alton (5 miles north-west).
Local landmarks in Blackmoor
We work in homes and buildings around Mill Chase Academy, among other places. The closest station to Blackmoor is Liss station, about 3.5 miles south of the centre. Well-known places in the area include The Romany Museum (2.3 miles west) and Chase Community Hospital (1.4 miles north-east). Green spaces nearby include Selborne Hill and Deadwater Valley.
For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we will plan the survey around it.
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Common questions in Blackmoor
Is Blackmoor in the area you cover?
Yes, Blackmoor is within the area we cover. We work right across London and the South East. Just phone 07833 053749 or send us an email and tell us about the property.
Is Blackmoor within the area you cover?
Yes. Blackmoor is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed as you book.
Will you repair the leak?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
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.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Just say which days work for you.
When to book a survey in Blackmoor
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
These are some of the problems a survey can pick up:
- Leaks at pipes, outlets or fixings
- Damage from equipment installers
- Leaks under green or ballasted roofs
- Leaking laps in the waterproofing
If you live in an older home near St Matthew's Church, the flat roofs on later extensions tend to wear out long before the main roof.
Before you book anyone
- What happens after the report arrives
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- What the survey will not cover
- How soon the report will arrive
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
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.
