How electronic leak detection works in Crowhurst
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. If you are worried about leaks at pipes, outlets or fixings and failed seams and laps, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Crowhurst may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
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.

Surveys for landlords and agents in Crowhurst
Letting agents can arrange access with tenants. Surveys run seven days a week, which helps when tenants work during the week.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Get leaks traced quickly
- Consider ELD before paving or planting goes on
- Limit access to the roof
- Ask contractors to protect the membrane
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
Do you need electronic leak detection in Crowhurst?
Holes in a membrane frequently come from feet, tools or debris. Some are too small to see, but still let water through.
A survey can pick up problems such as:
- Damp inside with no sign on the roof
- Leaks through a flat roof with no obvious cause
- Waterproofing to test before it’s covered
- Leaks at pipes, outlets or fixings
For an older house near a landmark such as Church of St George, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before booking
- What follow-up you get after the report
- Whether the price includes VAT
- What they won’t be able to tell you
- How they’ll see the roof: from ground level, the loft, the roof or by drone
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.

What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- The height of the building and how the roof can be seen safely
- The type of building, from a house to a block or an office
- How big the roof is
- Extra roofs, like extensions, dormers or garages
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
What to tell us when you contact us
The more you let us know, the easier it is to price the survey. When you contact us, tell us:
- When you need the report by
- Any photos you have, taken from the ground or a window
- Why you want a survey: buying, a leak, a storm or new work
- The style of property, from a terrace to a block
Booking is simple: just phone 07833 053749 or use the contact form, tell us about the property and we will suggest the right survey. The price is agreed up front.
How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. Around Crowhurst, older homes can have small or awkward roof spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- Keep pets inside or away from the areas we are looking at
- Mention any parking restrictions on your street
- Dig out any old roof reports or invoices

Advice
Questions from Crowhurst
Does a conservation area affect roof work in Crowhurst?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Crowhurst?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we’ll say so at the start.
What happens next?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you find leaks on a covered flat roof?
On some roofs, yes. What sits on the membrane affects the method so we check the roof first.
Flat and commercial roofs around Crowhurst
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses like Chartwell, about 4.7 miles north-east, show how far back building in the area around Crowhurst goes. 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.
If you let a flat or house near Godstone station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
