Monkhams Electronic Leak Detection
We take a careful look at the flat roof membrane at your property in Monkhams, and put it all in a written report with photographs.
- Leaks at pipes, outlets or fixings
- Leaks through a flat roof with no obvious cause
- Leaks showing away from the breach
Electronic leak detection in Monkhams: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We talk this through before we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. We will tell you if the roof can’t be tested. If you’ve noticed leaking laps in the waterproofing and leaks through a flat roof with no obvious cause, a survey will tell you what’s going on, whatever the roof.
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 Monkhams, 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 right away, and a good reference for later.

What electronic leak detection does not cover
It helps to know what a survey won’t do before booking:
- Water entering through details rather than the membrane
- Carrying out the repair work
- Areas we can’t reach or that can’t be tested
If you are not sure which survey you need, ring 07833 053749 or use the contact form and we’ll give you a straight answer before you book. The full list of what we check.

Monkhams: your questions answered
Do you cover Monkhams?
Yes. Our area covers London and South East England, and Monkhams is part of that. You can call 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Does a conservation area affect roof work in Monkhams?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof won’t work, we will say so before testing.
How much time does ELD need?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
What if it rains on the day?
It can, depending on the survey. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.

What affects the price in Monkhams
Prices vary from roof to roof, and it comes down to:
- The use of thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- House, block, shop or office
- Extra roofs, like extensions, dormers or garages
For a price for your roof in Monkhams, call 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.
Getting in touch
These details help when you contact us:
- Why you want a survey: buying, a leak, a storm or new work
- Any deadline, like an exchange date
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
Photos help, if you have them. Pictures from ground level or a window are fine. To send them or to book, ring 07833 053749 or use the contact form.
Landlords, agents and block managers in Monkhams
Letting agents can arrange access with tenants. Surveys run seven days a week, which can make access easier.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer.
Common roof problems in Monkhams
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Problems we come across often include:
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
- Leaks through a covered membrane
If you own one of the older houses in the streets near All Saints' Church, the joins between later flat roofs and the old walls are where problems usually start.
Questions to ask before booking
- How much experience they have with roofs like yours
- Whether VAT is in the quoted price
- Are they insured for the work?
- Whether any drone flown is registered with the CAA
Why act early in Monkhams
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. In Monkhams, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
The cost of a survey depends on the roof: 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.
Why book us in Monkhams
- A photo-illustrated written report
- 20+ years’ experience
- Weekday and weekend surveys
- Drones and thermal imaging where applicable

Flat and commercial roofs around Monkhams
The wider area around Monkhams has a long history of building, with Valentines Mansion about 3.6 miles south-east. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Highams Park station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Wells Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

How it works
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit typically takes a time that depends on the roof’s area and construction, which we set out in the quote. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Monkhams runs like any other.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Before we arrive
- Move anything stored under the loft hatch
- If you’re buying, let the agent know when we’re coming
- Check pets are kept safely away
