Landlords and agents in Hatfield Heath book surveys as well as homeowners. A report with photographs gives you a clear record of the flat roof membrane, useful for planning maintenance.
Letting agents can arrange access with tenants, at a time agreed beforehand. Surveys run seven days a week, which helps when tenants work during the week.
About our electronic leak detection in Hatfield Heath
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD won’t work on your roof at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that can’t give results. Common reasons to book are new membranes needing a check before handover and leaks under green or ballasted roofs, on liquid-applied waterproofing, green roofs and flat roof membranes.
Some older homes in villages like Hatfield Heath are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
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.

Useful tips for Hatfield Heath property owners
Over many surveys, some simple habits stand out:
- Keep foot traffic on flat roofs to a minimum
- Use boards when working on the roof
- Avoid repeated repairs without finding the cause
- Do not leave water getting in
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.

What else we do in Hatfield Heath
What happens on the day
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Hatfield Heath needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Let us know where we can park nearby
- Agree roof access with the managing agent if it is shared
- Find any records of previous roof work
Booking a survey

Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Common questions in Hatfield Heath
Do you cover Hatfield Heath?
Yes. We cover the whole of London and South East England, and Hatfield Heath is part of that. Just ring 07833 053749 or drop us an email and tell us about the property.
Does a conservation area affect roof work in Hatfield Heath?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.

It is a careful look at the flat roof membrane, not the whole story. Its limits include:
- Areas we can’t reach or that can’t be tested
- Roofs whose membrane or build-up isn’t suitable
- The extent of water in the insulation

Electronic leak detection around Hatfield Heath
In Essex, older buildings are often clay-tiled, many with weatherboarding, and a good many post-war and modern estates besides. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With Barrington Hall about 2.3 miles north-east, Hatfield Heath sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
If you let a flat or house near Sawbridgeworth station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Hatfield Heath Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For an older house near a landmark such as Holy Trinity Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

DIY checks: what’s safe
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
