How electronic leak detection works in Waltham St Lawrence
There are different ELD methods. Low-voltage testing is usually done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. If you’re worried about stains far from any visible defect and repairs that haven’t stopped the leak, we can find out what’s behind it, whatever the roof.
In a small place like Waltham St Lawrence, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Flat roofs in Waltham St Lawrence
About 4.7 miles north lies Harleyford Manor, a reminder of how long the area around Waltham St Lawrence has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you own a rental within reach of Twyford station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. The streets around a church such as Church of St Lawrence are frequently among the oldest in a place, and if your home is one of 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. Anyone responsible for a site like Waltham St Lawrence Primary School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a length of time set by the roof’s area and construction, which we set out in the quote. Somewhere like Waltham St Lawrence needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.

Advice
Questions from Waltham St Lawrence
How do I find out if my home in Waltham St Lawrence 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.
Is Waltham St Lawrence within the area you cover?
We do. A small place gets exactly the same survey as a big one.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when booking.
Can you inspect my roof with a drone?
Yes, where it’s 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.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
Can you survey in bad weather?
A survey can typically go ahead in light rain, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather isn’t suitable.
Leave it or get it looked at?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. In a small place like Waltham St Lawrence, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your survey before you book.

Tips that help
You don’t need to be a roofer to help. Here’s what helps most:
- Let us know about the membrane and build-up if you know it
- Do not keep patching the same spot
- Act on new leaks promptly
- Use boards when working on the roof
If anything in the report is not clear, ask us. We will explain what was found and what it means.
Make sure contractors protect the waterproofing when they work up there. Have the roof looked at after other work.

Checking the roof from ground level
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Surveys for landlords and agents in Waltham St Lawrence
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Where a roof is shared: we need access agreed with whoever owns or manages the building. Let us know about it when you book and we will plan the visit with that in mind.
