Electronic leak detection in Grahame Park, Greater London
Need electronic leak detection in Grahame Park? We can help, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Waterproofing to test before it’s covered
- Repairs that haven’t stopped the leak
- Stains far from any visible defect
Why get it checked now?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
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 the job before booking.
What you get with us
- More than 20 years surveying roofs
- A written report with photos

Electronic leak detection in Grahame Park: what you get
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. Common reasons to book are patched roofs that still leak and failed seams and laps, on roof terraces and balconies, commercial flat roofs and single-ply roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats 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 Grahame Park, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. In Grahame Park, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Preparing for the visit

Local flat roofs in Grahame Park
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Grahame Park has a long history of building, with Heath Hall about 3.5 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
The streets around a church such as St Augustine Grahame Park are often among the oldest in a place, and if your home is one of the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. For businesses in and around places such as Broadwalk Centre, a flat roof over a business is out of sight and out of mind until it leaks. Grahame Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway when you book, as a space near the door can’t be promised.

Grahame Park: your questions answered
Do you carry out roof surveys in Grahame Park?
Yes, Grahame Park is within the area we cover. We survey roofs across London and South East England. You can ring 07833 053749 or drop us an email with the address and a few details.
Is parking a problem for a survey in Grahame Park?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
How do you choose the testing method?
The roof decides the method. You’ll know which method we plan to use before we start.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.

What we look for on each type of roof
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
