EPDM rubber roofs frequently last 30–50 years, but punctures and seam failures still happen.
Electronic leak detection for homes and businesses in Brentford End
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you at the start. 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’ve noticed leaks through a covered membrane and repairs that haven’t stopped the leak, a survey will tell you what’s going on, whatever the roof.
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 Brentford End, 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.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.

Electronic leak detection in Brentford End: local notes
Syon House, about 0.5 miles south-east, is one of the historic houses in the wider area around Brentford End. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For businesses in and around places such as Treaty Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. For hotels and guest houses around Brentford End, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Clear flat roof outlets regularly
- Avoid repeated repairs without finding the cause
- Let us know about the membrane and build-up if you know it
- Get leaks traced quickly
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.

What else we do in Brentford End
Your questions about electronic leak detection in Brentford End
Will parking be an issue for a roof survey in Brentford End?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Does a conservation area affect roof work in Brentford End?
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.
Can you survey in bad weather?
It can, depending on the survey. Drones can’t fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.
How do I book a survey in Brentford End?
The quickest way is to phone 07833 053749 or use the contact form. Give us the address and some details about the roof, and we’ll take it from there. We survey seven days a week.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you work in Brentford End?
Yes. We carry out electronic leak detection in Brentford End, and the service is the same as everywhere else we work.
What we do, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Brentford End runs like any other.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
How to prepare
- Show us where any leaks or stains appear
- Mention any parking restrictions on your street
- Leave a clear route to the loft
