Haverstock Electronic Leak Detection
A careful look at the flat roof membrane at your property in Haverstock, and put it all in a report with photographs.
- Failed seams and laps
- Repairs that haven’t stopped the leak
- Breaches around outlets and penetrations
Electronic leak detection in Haverstock
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a report with photographs. Common reasons to book are leaks showing away from the breach and leaks under green or ballasted roofs, across green roofs, single-ply roofs and commercial flat roofs.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Haverstock, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What electronic leak detection doesn’t cover
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Carrying out the repair work
- Parts of the roof covered by fixed equipment
- Leaks from walls, copings or rooflights
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you before you book. What a survey covers and does not.
What we check
- Flat roof membranes
- Commercial flat roofs
- Single-ply roofs
- Green roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
Flat roofs in Haverstock
With Keats House about 0.8 miles north, Haverstock sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Within a mile and a half or so of Haverstock there are several hotels, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
Take an older house close to Church of St Mary the Virgin: the flat roofs on later extensions tend to wear out long before the main roof. Shop and office owners around O2 Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. If you run a hotel or guest house in or near Haverstock, a roof problem can mean rooms out of use.
Haverstock is about 1 mile south-east of Hampstead, in Greater London. From houses to flats and shops in Haverstock, the roof can be surveyed. Our area takes in places right across Greater London.

Why it’s worth a survey now in Haverstock
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.

What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. You are welcome to ask questions while we’re there. In Haverstock, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- Make sure pets are kept safely away
- Leave a clear route to the loft
- If the roof is shared, arrange access with whoever manages the building

Haverstock: your questions answered
Is my home in Haverstock 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.
Will parking be an issue for a roof survey in Haverstock?
Usually it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or drop us an email.
How many surveys have you done?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
How does ELD work?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That’s how we locate breaches you cannot see.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Share any details you have and we’ll confirm suitability.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
DIY checks: what’s safe
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
