Electronic leak detection in Smallfield
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. If neither method suits your roof, we’ll tell you before any testing starts. We survey single-ply roofs, commercial flat roofs and liquid-applied waterproofing, and the problems we are asked to look at most are leaks through a covered membrane and leaks through a flat roof with no obvious cause.
Around a smaller place like Smallfield, flat roofs typically cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs. Ponding, splits and lifting edges are the signs to look for from a window.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

The survey, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. A visit to a smaller place like Smallfield is no different on the day: we look from ground level, from windows, from the loft and from the roof where it’s safe. It helps to show us anything you’ve already noticed.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Before we arrive
- Check the loft hatch can be reached
- Dig out any old roof reports or invoices
- Point out any leaks or damp patches

What a survey costs
To price your survey, we look at:
- Commercial roofs and larger buildings
- Features like valleys, chimneys, dormers and parapets
- The number of roofs, including extensions and garages
- The use of thermal imaging or a drone
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.
What to tell us when you get in touch
If you can, have these to hand when you contact us:
- Dates you’re working to, like exchange
- The reason for the survey, like buying, a leak or storm damage
- What kind of property and roof it is

Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or send us an email.
What we look for on each type of roof
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.

What else we do in Smallfield
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Tradespeople may need to travel further to a smaller place like Smallfield, so it is useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Honest limits
A survey is a careful look at the flat roof membrane, but it cannot do everything. Its limits include:
- Repairing the breaches (that’s for your roofer)
- Parts of the roof covered by fixed equipment
- Water entering through details rather than the membrane
If you’re not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer. What our survey covers.
Roof types and parts we check
- Roof terraces and balconies
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Green roofs
- Flat roof membranes
Signs you need electronic leak detection in Smallfield
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems such as:
- Leaks under green or ballasted roofs
- A flat roof leak that can’t be traced
- Holes left by work on the roof
- Stains far from any visible defect
If you let a flat or house near Horley station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before you book
- What they will not be able to tell you
- When you will get the report
- Which parts of the roof they’ll actually see
- Will they check the loft as well as the outside?
Smallfield questions
Is there anything to prepare before you come to Smallfield?
It’s useful to clear access to the loft, and to let us know about leaks, damp patches or recent work. Let us know about parking and access in Smallfield too.
Do you cover Smallfield?
Yes, Smallfield is within the area we cover. We survey roofs across London and South East England. You can ring 07833 053749 or use the contact form with the address and a few details.
Will you photograph what you find?
Yes. Photographs are part of every report, so you can see each point for yourself.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Does someone need to be in?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Is my roof suitable for ELD?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. We’ll tell you if yours isn’t suitable before testing.
