Electronic leak detection in Chadwell St Mary
Our ELD testing covers flat roofs in Chadwell St Mary and the rest of London and the South East. A visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. Typical surveys look at leaks that return after repairs and new membranes needing a check before handover, on roof terraces and balconies, flat roof membranes and green roofs.
Around Chadwell St Mary, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when booking. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Where we cannot see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

Tips that help
You don’t need to be a roofer to help. What helps most:
- Don’t leave water getting in
- Check new waterproofing before handover
- Check trades protect the waterproofing
- Keep a note of leaks after rain
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Check contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. Around Chadwell St Mary, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. Dealing with the cause is simple; drying out a wall is not.

Your questions about electronic leak detection in Chadwell St Mary
How do I find out if my home in Chadwell St Mary 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.
Do roofs near the sea, like those around Chadwell St Mary, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details like ridges, verges, flashings and metal fixings are the ones to watch, and Chadwell St Mary is within about 3 miles of the coast.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Do you work in Chadwell St Mary?
Yes. We cover Chadwell St Mary and the rest of Thurrock, as part of our work across London and South East England. To book, call 07833 053749 or use the contact form.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Share any details you have and we’ll confirm suitability.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.
Different roofs, different checks
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Prices for electronic leak detection in Chadwell St Mary

Flat and commercial roofs around Chadwell St Mary
The coast is about 3 miles or less from Chadwell St Mary, and places near the sea get more salt in the air and more wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there.
If you look after a shop, office or commercial unit, for instance near Ealing Broadway Centre, a flat roof over a business is out of sight and out of mind until it leaks. If you own a rental within reach of East Tilbury station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building like Herringham Primary Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
