Signs you need electronic leak detection in Northfleet
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in for months before it shows.
People normally book a survey after spotting one of these:
- Water coming in under a flat roof
- Punctures from foot traffic or tools
- Leaks under green or ballasted roofs
- New membranes needing a check before handover
Shop and office owners around Bluewater may find that a flat roof over a business is out of sight and out of mind until it leaks.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- Whether you can ask questions once you have the report
- What they will not be able to tell you
- Whether the loft is part of the inspection
About our electronic leak detection in Northfleet
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. If you are worried about a flat roof leak that can’t be traced and holes left by work on the roof, a survey will tell you what’s going on.
In a town like Northfleet, flat roofs are common on rear extensions, garages, porches and dormers. Many are felt, and newer ones may be EPDM rubber or GRP. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Water that sits for days after rain is often the first sign a flat roof needs attention.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Flat and commercial roofs around Northfleet
Northfleet is within about 3 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. There are several hotels within about a mile and a half of Northfleet, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Landlords with a home close to Gravesend station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. Historic houses such as Cobham College, about 3.7 miles south-east, show how far back building around Northfleet goes. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect as long as needed for the roof’s area and construction, which we set out in the quote. For a home in Northfleet, the main things we need are a way into the loft, a route to the back garden and somewhere to park. Someone needs to let us in, so let us know who that will be.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Preparing for the visit
- Have any paperwork from past roof work to hand
- Point out any leaks or damp patches
- Make sure pets are kept safely away

Advice
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep outlets clear of debris
- Ask contractors to protect the membrane
- Consider ELD before paving or planting goes on
- Get leaks traced quickly
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
FAQs for Northfleet
Is the coastal weather around Northfleet hard on roofs?
It can do. Within about 3 miles of the sea, as Northfleet is, metal fixings wear faster and gales find any loose ridge or slate.
Do you cover commercial flat roofs around Northfleet?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Can you inspect my roof with a drone?
Yes, where it’s applicable. 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.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or send us an email.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and anything out of sight is recorded in the report.
What happens if roof problems are left?
Patching where you think the leak is frequently misses it. Testing shows where the membrane is actually breached. Around Northfleet, gutters that overflow soak the wall below. At roof level, a loose tile or tired flashing does the same. Neither gets better on its own.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
