About our electronic leak detection in Grays
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you’ve noticed leaks under green or ballasted roofs and punctures from foot traffic or tools, a survey will tell you what’s going on, whatever the roof.
In a town like Grays, a good many shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile. A survey, or electronic testing where the membrane suits it, shows what’s going on. If someone else manages the building, let us know so roof access can be arranged.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Tips that help
These tips come from what we see on roofs every week:
- Act on new leaks promptly
- Note where leaks show inside and when
- Use boards when working on the roof
- Find the breach before more patching
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
How the survey works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. A typical visit in Grays begins with the street side of the roof and then moves round the building. Rear gardens and side paths frequently give the best view of extensions and back slopes. Then, if it can be reached safely, we look in the loft.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Agree roof access with the managing agent if it’s shared
- Keep pets in another room
- Clear the way to the loft hatch

Advice
Questions from Grays
Does being near the coast affect roofs in Grays?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
How do I find out if my home in Grays is listed?
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.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
How do I arrange electronic leak detection in Grays?
Just ring 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Do you need electronic leak detection in Grays?
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Here are some of the things we see often:
- Waterproofing to test before it’s covered
- Holes around roof penetrations
- Water coming in under a flat roof
- Damp inside with no sign on the roof
Take an older house close to St John the Evangelist: the joins between later flat roofs and the old walls are where problems normally start.
What to check before booking
- How long they’ve been surveying roofs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What exactly goes into their report
- What happens after the report arrives
What electronic leak detection looks like in Grays
The coast is about 4 miles or less from Grays, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to Grays station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings such as Quarry Hill Academy, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

How the survey changes by roof type
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
What affects the price in Grays
Prices vary from roof to roof, and it comes down to:
- The type of building, from a house to a block or an office
- How many separate roofs there are, such as extensions, dormers and garages
- How complicated the roof is, with its valleys, chimneys and parapets
- The size of the roof
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 roof before booking.
What we need to know
What helps most when you contact us:
- What’s prompted the survey
- Your postcode, so we can check access and travel

Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Around Grays, gutters that overflow soak the wall below. A slipped tile or worn flashing does the same higher up. Neither gets better on its own.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
