When to book a survey in Castle Green
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
It’s worth booking a survey if you’ve seen:
- Waterproofing to test before it’s covered
- Leaks through a covered membrane
- Damage from equipment installers
- Gaps at membrane joints
If you let a flat or house near Barking Riverside station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- How long the report takes to arrive
- Will the report include photos?
- What happens after the report arrives
How electronic leak detection works in Castle Green
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. We survey liquid-applied waterproofing, roof terraces and balconies and commercial flat roofs, and people most often book us about patched roofs that still leak and new membranes needing a check before handover.
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 Castle Green shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What a survey costs
Several things affect the price of a survey:
- Extra roofs, like extensions, dormers or garages
- Whether thermal imaging or a drone is needed
- The roof’s overall size
- Commercial roofs and larger buildings
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before booking.

What else we do in Castle Green
The survey, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a London area like Castle Green, the main things to sort out are parking and access: 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 ground level, windows, the loft and, where it’s safe, the roof itself.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Show us where any leaks or stains appear
- Leave a clear route to the loft
- Agree roof access with the managing agent if it is shared
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or drop us an email with the address and the days you’d prefer.

Electronic leak detection in Castle Green: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. 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. Eastbury Manor House, about 1 mile west, is one of the historic houses in the wider area around Castle Green. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If your house is among the older ones in the streets near St John the Divine, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a shop, office or commercial unit, for example near Gallions Reach Shopping Park, flat roofs over shops and units are easy to forget until water comes through a ceiling.

FAQs for Castle Green
Is Castle Green in the area you cover?
Yes, Castle Green is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Can parking be tricky for a visit in Castle Green?
Parking in Castle Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
How long will testing take?
Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so the building owner or managing agent needs to agree access. We can only inspect what we’re given access to.
How do I book a survey in Castle Green?
Simply phone 07833 053749 or email us with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
For a price for your roof in Castle Green, ring 07833 053749 or drop us an email and tell us about the roof. The price is agreed before a date is set.

- The extent of water in the insulation

- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
- Single-ply roofs
- Liquid-applied waterproofing
- Green roofs
What you can safely check yourself
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
