What we do, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes a length of time set by the roof’s area and construction, which we set out in the quote. In Moorhouse Bank, visits are available on weekdays and at weekends. 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.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- Make sure the loft hatch can be reached
- Have any paperwork from past roof work to hand
- Tell us where we can park nearby

Advice
Electronic leak detection in Moorhouse Bank
We carry out electronic leak detection on flat roofs in Moorhouse Bank and across London and the South East. Testing usually takes a time that depends on the size of the roof and how it’s built, and we’ll give you a guide when quoting. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a photo-illustrated written report. We’re often asked to look into new roofs to check before paving or planting and holes left by work on the roof, across single-ply roofs, liquid-applied waterproofing and roof terraces and balconies.
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 Moorhouse Bank, the flat roof is frequently a shared part of the building.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Common questions in Moorhouse Bank
Do you carry out roof surveys in Moorhouse Bank?
Yes, Moorhouse Bank is one of the places we work. The survey and report are the same in Moorhouse Bank as anywhere else, and visits run on weekdays and weekends.
Is my home in Moorhouse Bank listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Does the weather affect the survey?
Light rain does not usually stop a survey, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather isn’t suitable.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on any day of the week. To find a day that suits you, phone 07833 053749 or drop us an email.
Common roof problems in Moorhouse Bank
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in long before anyone notices.
Things that often lead to a survey include:
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
- Leaks through a flat roof with no obvious cause
- Gaps at membrane joints
As a London address, Moorhouse Bank can be tricky for parking: a visitor permit or a nearby bay makes the day easier.
Choosing a roof surveyor
- Which parts of the roof they’ll actually see
- How long the report takes to arrive
- What’s outside the scope of the survey
- Is VAT included in the price?
Different roofs, different checks
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
How we price electronic leak detection
Not every roof costs the same to survey, for these reasons:
- The use of thermal imaging or a drone

- Roof area
- Features like valleys, chimneys, dormers and parapets

Surveys for landlords and agents in Moorhouse Bank
Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant beforehand.
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we will plan the visit with that in mind.
Flat and commercial roofs around Moorhouse Bank
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in 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. About 1.3 miles east lies Quebec House, a reminder of how long the area around Moorhouse Bank has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to St Andrew's: flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building like Oxted School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
