About our electronic leak detection in Dalston
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you are worried about leaks through a flat roof with no obvious cause and damage from equipment installers, a survey will tell you what’s going on.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Dalston, the flat roof is frequently a shared part of the building.
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.

How it works
Where it is relevant and can be reached safely, the loft 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 more time on a big roof than a small one, with the construction of the roof playing a part too. Surveys in Dalston can be booked for any day of the week. 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.

Advice
Different roofs, different checks
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We will say if the test will not work.

What else we do in Dalston
Why act early in Dalston
Patching where you think the leak is often misses it. ELD shows the actual breach points. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there is time to plan.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

Common questions in Dalston
Do you cover commercial flat roofs around Dalston?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building.
How do I find out if my home in Dalston is listed?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover Dalston?
Yes. We cover Dalston and the rest of Greater London, as part of our work across London and the South East. To book, ring 07833 053749 or drop us an email.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
What a survey costs
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
- The type of building, from a house to a block or an office
- Any need for thermal images or a drone flight
For a price for your roof in Dalston, call 07833 053749 or email us and tell us about the roof. We’ll confirm the figure before booking.
Booking your survey
Some details help us recommend the right survey and price. When you contact us, it helps to mention:
- The kind of building and roof involved
- Where any leaks, stains or damp patches show inside
- Anything about access we should know
- Dates you’re working to, such as exchange
Most bookings start with a short call: ring 07833 053749 or use the contact form. You’ll have a price before anything is arranged.
What we are asked to look at in Dalston
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Look out for signs like these:
- Breaches around outlets and penetrations
- New roofs to check before paving or planting
- Leaks that return after repairs
- Leaks showing away from the breach
If you own one of the older houses in the streets near Holy Trinity Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before booking any roof surveyor

- How they plan to inspect the roof safely
- Whether any drone flown is registered with the CAA
- How soon the report will arrive
What electronic leak detection looks like in Dalston
The wider area around Dalston has a long history of building, with Sutton House about 0.9 miles east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. There are several hotels within about a mile and a half of Dalston, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you run a business near Hackney Walk, flat roofs over shops and units are easy to forget until water comes through a ceiling. Anyone responsible for a site like Holy Trinity Church of England Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
