About our electronic leak detection in Westmill
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a written report with photos of each breach found. We are frequently asked to look into breaches hidden under paving or planting and leaks that return after repairs, on flat roof membranes, roof terraces and balconies and liquid-applied waterproofing.
Around Westmill, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when booking. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Where we can’t see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Electronic leak detection around Westmill
If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For landlords with property near Hitchin station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to St Mark's: the joins between later flat roofs and the old walls are where problems normally start. Anyone responsible for a site like Oughton Primary and Nursery School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Questions from Westmill
Do you cover smaller places like Westmill?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route as you book.
Do you cover Westmill?
We do. The survey and report are the same in Westmill as anywhere else.
Can you survey a shared roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We can only inspect what we are given access to.
How do I book a survey in Westmill?
Just ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.
How much time does ELD need?
It normally takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Is this an asbestos survey?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
For landlords and managing agents
With a portfolio of properties, surveys can be booked for more than one address. To discuss a number of properties, call 07833 053749 or email us.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
What we look for on each type of roof
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
How it works
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. The survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. A visit to Westmill is planned like any other: the time, the access and where to park are agreed beforehand. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- For flats, make sure roof access has been agreed
- If it is not your property yet, arrange access through the agent

Useful tips for Westmill property owners
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Don’t keep patching the same spot
- Tell us about the membrane and build-up if you know it
- Record dates and spots where water appears
- Limit access to the roof
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
What happens if roof problems are left?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached so attention can go to the right place. In an older home around Westmill, water from a roof defect can get into timber and plaster, which is far harder to put right than the roof fault itself.
To find out what your survey will cost, ring 07833 053749 or use the contact form with the address and a few details. The price is agreed before a date is set.
