About our electronic leak detection in Pimlico
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. If you are worried about leaking laps in the waterproofing and water coming in under a flat roof, we can find out what’s behind it.
Somewhere as small as Pimlico, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Common questions in Pimlico
How do I find out if my home in Pimlico is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is Pimlico within the area you cover?
Yes, we do. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you survey in bad weather?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Can you find leaks on a covered flat roof?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We’ll discuss it before we quote.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
What’s the best way to book?
Just call 07833 053749 or use the contact form. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Before and after the survey
Most of what helps is simple and safe from ground level. A few suggestions:
- Make sure trades protect the waterproofing
- Test new membranes before covering them
- Do not leave water getting in
- Let us know about the membrane and build-up if you know it
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.

What else we do in Pimlico
Flat roofs in Pimlico
Historic houses like High Elms Manor, about 2.2 miles south-east, show how far back building in the area around Pimlico goes. 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. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Landlords with a home close to Kings Langley station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. For businesses in and around places such as Village Arcade St Albans, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take an older house close to Church of the Ascension: the flat roofs on later extensions tend to wear out long before the main roof.
Pimlico is about 2 miles south-east of Hemel Hempstead, in Hertfordshire. Wherever you are in Pimlico, we can come and survey your property. Across Hertfordshire, we cover Pimlico and the places around it. There’s also a page for London.

The nearest railway station is Kings Langley station, roughly 1.9 miles south-west of the centre.

Rented homes, blocks and businesses
We survey roofs for landlords and agents as well as homeowners. A photo-illustrated written report gives you a clear record of the flat roof membrane.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, and they’re priced for the size.
How it works
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. In a hamlet or village like Pimlico, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- If you’re buying, check with the agent that we can get in
- Gather any invoices or paperwork from past roof work
- Agree roof access with the managing agent if it is shared
Getting a price
Getting a price is simple: just phone 07833 053749 or send us an email and give us some details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
Advice
How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- How many separate roofs there are, such as extensions, dormers and garages
- How big the roof is
- Whether thermal imaging or a drone is needed
- How complicated the roof is, with its valleys, chimneys and parapets
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Helping us price your survey
Getting the details right at the start saves time. It’s useful to include:
- Your timetable, such as an exchange date
- What made you get in touch
- Pictures of the roof from a safe spot, if you have them
- Where the property is, with the postcode
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or send us an email.
Why get it checked now?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Outbuildings and barns around Pimlico are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.
