How electronic leak detection works in Eel Pie Island
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. If your roof isn’t suitable, we’ll tell you at the start. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey single-ply roofs, roof terraces and balconies and flat roof membranes, and the problems we are asked to look at most are leaks showing away from the breach and leaking laps in the waterproofing.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Eel Pie Island, the flat roof is often a shared part of the building.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

Flat roofs in Eel Pie Island
There are several hotels within about a mile and a half of Eel Pie Island. If you look after one, a leak through a flat roof can put a room out of use. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take an older house close to St Mary's Church: flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as St Mary's Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What we cannot see

- Repairing the breaches (that is for your roofer)
- Areas we cannot reach or that can’t be tested
- Leaks from walls, copings or rooflights

Signs you need electronic leak detection in Eel Pie Island
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Problems we come across often include:
- Damage from equipment installers
- Leaks through a flat roof with no obvious cause
- Repairs that haven’t stopped the leak
- Holes around roof penetrations
For hotels and guest houses around Eel Pie Island, a roof problem found early is far less disruptive than one found by a guest.
Choosing a roof surveyor
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- How soon the report will arrive
- What insurance they carry
- Whether any drone flown is registered with the CAA
Why it is worth a survey now in Eel Pie Island
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.

FAQs for Eel Pie Island
How do I find out if my home in Eel Pie Island is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you look at commercial flat roofs near Eel Pie Island, such as hotels?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Do I need to be at home?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you contact us and we will explain what’s needed.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
What do I do with the report?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years.
How we price electronic leak detection
To price your survey, we check:
- Building height and the viewpoints available
- The shape of the roof and its details
- The use of thermal imaging or a drone
- The type of building, from a house to a block or an office
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.
Booking your survey
Getting the details right at the start saves time. It’s useful to include:
- When you need the report by
- The style of property, from a terrace to a block
- Your postcode, so we can check access and travel
- The reason for the survey, such as buying, a leak or storm damage
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or drop us an email.
What happens on the day
We will ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a visit in Eel Pie Island, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it is safe, the roof itself.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Tell us about parking before the day
- Dig out any old roof reports or invoices
Arrange a survey
Most bookings start with a short call: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.
