Prices for electronic leak detection in Three Mills
Not every roof costs the same to survey, for these reasons:
- How many separate roofs there are, such as extensions, dormers and garages
- Commercial roofs and larger buildings
- Height and safe access
- Whether thermal imaging or a drone is needed
For a price for your roof in Three Mills, phone 07833 053749 or drop us an email and let us know about the roof. We will confirm the figure before booking.
Booking your survey
You don’t need to know any roofing terms. Just tell us:
- Pictures from the garden or a window, if you have them
- Access details, such as a loft hatch or a shared roof
- Where the property is, with the postcode
- What’s prompted the survey
Every survey is priced before it is booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, phone 07833 053749 or email us.
How electronic leak detection works in Three Mills
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points instead of hunting for the leak. We don’t estimate repair costs; that is for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and the problems we are asked to look at most are water coming in under a flat roof and failed seams and laps.
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. In Three Mills, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

Common questions in Three Mills
Is my home in Three Mills listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s 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.
Can you look at the flat roof of a hotel or office near Three Mills?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when you book.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Do you cover Three Mills?
Yes. We survey roofs in Three Mills and the rest of Greater London, as part of our work across London and the South East. For a price, phone 07833 053749 or send us an email.
What happens after the survey?
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.
Do you look in the roof space?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
Flat roofs in Three Mills
The wider area around Three Mills has a long history of building, with Sutton House about 2.4 miles north-west. 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 a listed home or one in a conservation area may need consent for changes of material. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church like St Mary's Church are often among the oldest in a place, and if your house is among the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For hotels and guest houses around Three Mills, a roof problem found early is far less disruptive than one found by a guest.

Different roofs, different checks
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Green and ballasted roofs
ELD is easier on a new roof before it’s covered.
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Don’t keep patching the same spot
- Stay off the flat roof unless needed
- Act on new leaks promptly
- Check new waterproofing before handover
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
How it works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes longer on a large roof than a small one, with the construction of the roof playing a part too. In Three Mills, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Let us know about parking near the property
- Point out any leaks or damp patches
- Buyers: confirm access with the estate agent or seller

Related advice
When to book a survey in Three Mills
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
A survey can pick up problems such as:
- Stains far from any visible defect
- Water coming in under a flat roof
- Leaks through a covered membrane
- Holes left by work on the roof
For site and facilities teams at buildings like East London Science School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book anyone
- Will they check the loft as well as the outside?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Will the report include photos?
- Are they insured for the work?
