Electronic leak detection for homes and businesses in Dudswell
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. If you’ve noticed leaking laps in the waterproofing and patched roofs that still leak, a survey will tell you what’s going on.
Some older homes in villages like Dudswell are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
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, whichever applies.

What we’re asked to look at in Dudswell
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
A survey can pick up problems such as:
- Waterproofing to test before it is covered
- Leaking laps in the waterproofing
- Holes left by work on the roof
- Holes around roof penetrations
Anyone responsible for a site like St Mary's CofE Primary School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

The survey, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Somewhere as small as Dudswell, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof and where water is showing.
- 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.
- You get a report with photos of each breach.
Before the survey
- Unlock side gates and any roof access doors
- Mention any parking restrictions on your street
- Have any questions written down, so nothing gets missed
Booking a survey
Photos help, if you have them. Pictures from the ground or a window are fine. To get started, call 07833 053749 or drop us an email.
Advice
Dudswell: your questions answered
Is Dudswell within the area you cover?
Yes. Dudswell is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Just mention lanes, gates or anything else about the route when booking.
Is my home in Dudswell listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
How we price electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- The roof’s overall size
- Whether it is a home or a commercial building
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can safely be seen
For a price for your roof in Dudswell, ring 07833 053749 or use the contact form with the address and some details. The price is agreed before a date is set.
Getting in touch
To price your survey accurately, we’ll ask about:
- The address and postcode of the property
- What made you get in touch
- Any photos you have, taken from ground level or a window
- Anything about access we should know
Booking is simple: just phone 07833 053749 or drop us an email, let us know about the property and we will recommend the right survey. We confirm the price before anything is booked.
What you can safely check yourself
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
What you cannot do safely is get up close. Roofs are fragile and slippery. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. Testing helps find them.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Flat and commercial roofs around Dudswell
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses like Cholesbury Manor House, about 2.7 miles south-west, show how far back building in the area around Dudswell goes. 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 own a rental within reach of Tring station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark such as Church of Saint Mary, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
