Electronic leak detection for homes and businesses in Waddon
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof cannot be tested. We survey flat roof membranes, liquid-applied waterproofing and single-ply roofs, and the problems we’re asked to look at most are leaking laps in the waterproofing and leaks under green or ballasted roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Waddon shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what is not.

Questions from Waddon
Is my home in Waddon listed or in a conservation area?
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.
Can you look at the flat roof of a hotel or office near Waddon?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you will get a quote based on the building.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
How long does electronic leak detection take?
It normally takes a time that depends on the membrane area and the build-up, which we set out in the quote.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Does the report include photos?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What we do, step by step
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Surveys in Waddon can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- 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.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Leave a clear route to the loft
- Tell us about any leaks, stains or damp patches you know of
- Let us know about parking before the day
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.

Surveys for landlords and agents in Waddon
Letting agents often book on a landlord’s behalf. We agree a time with the tenant beforehand.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays, Saturdays and Sundays, which can make access easier.
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in, using safe viewpoints and a drone where it applies.
What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Any need for thermal images or a drone flight
- The shape of the roof and its details
- The number of roofs, including extensions and garages
- House, block, shop or office
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
Helping us price your survey
What helps most when you contact us:
- What kind of property and roof it is
- How the loft is reached, if there is one
- Photos of the roof, taken safely from the ground or a window
- Where the property is, with the postcode
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we will ask about the building and what you need. You will have a price before anything is arranged.
Roof by roof
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.

Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for your roof before you book.

What electronic leak detection looks like in Waddon
Waddon has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. With Addington Palace about 3.1 miles east, Waddon sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If you run a hotel or guest house in or near Waddon, a roof problem can mean rooms out of use. If you look after a shop, office or commercial unit, for example near St George's Walk, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building such as Aerodrome Primary Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
