How electronic leak detection works in Peaks Hill
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. We are often asked to look into waterproofing to test before it’s covered and leaks at pipes, outlets or fixings, on single-ply roofs, flat roof membranes and commercial flat roofs.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Peaks Hill, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Your questions about electronic leak detection in Peaks Hill
Do you cover Peaks Hill?
Yes, Peaks Hill is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or drop us an email with the address and some details.
Does a conservation area affect roof work in Peaks Hill?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. We will talk about access when you book.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and phone 07833 053749 or email us for a quote.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method so we check the roof first.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.

Signs you need electronic leak detection in Peaks Hill
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
We’re often asked to look at:
- Damp inside with no sign on the roof
- Damage from equipment installers
- Water coming in under a flat roof
- Breaches around outlets and penetrations
Take a building like Coloma Convent Girls' School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- Whether you can ask questions once you have the report
- How long they’ve been surveying roofs
- Whether the roof space is looked at, where there is one
- What insurance they carry
Tips from our surveys
Here are a few things we’d tell any owner:
- Keep outlets clear of debris
- Have roof specifications to hand
- Do not keep patching the same spot
- Get leaks traced quickly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Checking the roof from ground level
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.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- How many separate roofs there are, such as extensions, dormers and garages
- Whether thermal imaging or a drone is needed
- The type of building, from a house to a block or an office
- Height and safe access
To find out what your survey will cost, ring 07833 053749 or email us with the address and some details. The price is agreed before a date is set.
Getting in touch
Getting the details right at the start saves time. It’s useful to include:
- Your postcode, so we can check access and travel
- The style of property, from a terrace to a block
- When you need the report by
- What made you get in touch
To arrange a survey, call 07833 053749 or use the contact form with the address and what you’d like to know about the roof. We’ll confirm the price before booking.
What happens on the day
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. In Peaks Hill, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- 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.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Mention any parking restrictions on your street
- Let us know about any leaks, stains or damp patches you know of
- Jot down any questions you want answered
