Electronic leak detection for homes and businesses in Southgate
Not every flat roof suits electronic testing. Certain membranes conduct electricity, 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. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, flat roof membranes and commercial flat roofs, and the problems we are asked to look at most are leaks through a covered membrane and holes around roof penetrations.
Outbuildings, garden rooms and garages in places like Southgate often have flat roofs of their own. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Your questions about electronic leak detection in Southgate
My home in Southgate has a flat-roofed garage or porch. Is it worth having that looked at?
Often, yes, so mention it as you book. Flat-roofed garages and porches are common in new towns like Crawley, and older felt coverings may be near the end of their life.
Do you cover smaller places like Southgate?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
What will the report tell me?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or use the contact form.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
How do I book a survey in Southgate?
The quickest way is to ring 07833 053749 or drop us an email. Give us the address and a few details about the roof. Surveys run seven days a week.
Flat roofs in Southgate
About 5 miles south lies Tyes Place, a reminder of how long the area around Southgate has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Crawley, which Southgate is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all.
Shop and office owners around County Mall may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. Anyone responsible for a site like Southgate Primary will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Signs you need electronic leak detection in Southgate
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Most people get in touch when they’ve noticed one of these:
- Stains far from any visible defect
- Punctures from foot traffic or tools
- Failed seams and laps
- Holes around roof penetrations
If you own a rental within reach of Crawley station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Practical tips
Nothing here needs a ladder. Our suggestions:
- Do not let outlets block
- Get leaks traced quickly
- Keep a note of leaks after rain
- Don’t keep patching the same spot
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Surveys for landlords and agents in Southgate
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
What happens on the day
Safety comes first on every visit. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a smaller place like Southgate, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- 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.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Have any paperwork from past roof work to hand
- Point out any leaks or damp patches
- Clear the way to the loft hatch
