Electronic leak detection in Letchworth Garden City
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We will say if ELD will not work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It avoids arranging a test that can’t give results. If you are worried about leaks at pipes, outlets or fixings and new membranes needing a check before handover, we can find out what’s behind it, on green roofs, flat roof membranes and commercial flat roofs alike.
Around Letchworth Garden City, many garages, porches and extensions have flat roofs of their own. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed. Each kind of covering, from felt to rubber and GRP, is checked in its own way. Asbestos testing is not part of what we do, though a report may flag materials that could contain it.
The report records the flat roof membrane as we found it on the day. It’s useful right away, and a good reference for later, for example when you want to check whether anything has changed.

What electronic leak detection looks like in Letchworth Garden City
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Hinxworth Place about 4.6 miles north, Letchworth Garden City sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Letchworth Garden City station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. The streets around a church such as St Michael are often among the oldest in a place, and if your house is among the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Can I check my roof myself?

Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.

Questions from Letchworth Garden City
How do I find out if my home in Letchworth Garden City is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is there anything to prepare before you come to Letchworth Garden City?
Very little. Unlock side gates, keep pets in another room and dig out any invoices from past roof work, and the visit in Letchworth Garden City can get straight on.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
How experienced are you?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
How long will testing take?
Testing normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
