Electronic Leak Detection in Sandridge
Electronic leak detection in Sandridge and the rest of Hertfordshire. We survey on weekdays and at weekends.
- Waterproofing to test before it is covered
- Leaks at pipes, outlets or fixings
- Water coming in under a flat roof
How electronic leak detection works in Sandridge
You get a report showing the location of each breach, with photographs. Your roofer can then repair those points rather than guessing. We do not estimate repair costs, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. If you are worried about leaking laps in the waterproofing and leaks through a covered membrane, we can find out what’s behind it.
Somewhere as small as Sandridge, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when you book.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Local flat roofs in Sandridge
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Childwickbury Manor, about 2 miles west, is one of the historic houses in the wider area around Sandridge. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you live in an older home near St Leonard's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you run a business near The Maltings, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Why get it checked now?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. For an older or listed building in a place like Sandridge, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.

What happens on the day
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. In a small place like Sandridge, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You tell us about the roof and where water is showing.
- 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.
- A report with photographs shows where each breach is.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Make sure we can get to the back of the property
- Gather any invoices or paperwork from past roof work
Arrange a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or drop us an email whenever suits you.

Common questions in Sandridge
Is Sandridge within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Do you carry out roof surveys in Sandridge?
Yes. Our area covers London and South East England, and Sandridge is part of that. Just call 07833 053749 or send us an email and tell us about the property, and we’ll talk through which survey suits.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know as you book.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or drop us an email.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.

When to book a survey in Sandridge
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in which makes it hard to find by looking.
Signs worth acting on include:
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Patched roofs that still leak
Anyone responsible for a site like Sandridge School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Questions to ask before booking
- Their report turnaround times
- How long they’ve been surveying roofs
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether the price includes VAT
Different roofs, different checks
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible, depending on the build-up.
What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Prices for electronic leak detection in Sandridge
A few things affect what a survey costs:
- Height and safe access
- How many separate roofs there are, such as extensions, dormers and garages
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Getting in touch
You don’t need to know any roofing terms. It’s enough to tell us:
- When you need the report by
- What kind of property and roof it is
- The property’s address and postcode
- The reason for the survey, such as buying, a leak or storm damage
A quick phone call is normally the easiest start: phone 07833 053749 or email us and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
