How electronic leak detection works in Broom Hill
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. 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. If testing isn’t possible, we will say so. If you’ve noticed leaks under green or ballasted roofs and damage from equipment installers, we can find out what’s behind it.
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 Broom Hill, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Can I check my roof myself?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Do you need electronic leak detection in Broom Hill?
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in which makes it hard to find by looking.
Things that frequently lead to a survey include:
- Breaches around outlets and penetrations
- Leaks showing away from the breach
- Breaches hidden under paving or planting
- Water coming in under a flat roof
For businesses in and around places such as The Mall, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Before you book anyone
- What the survey will not cover
- Whether any drone flown is registered with the CAA
- When you will get the report
- Whether the price includes VAT
What a survey costs
Prices always include VAT. The things that change the price are:
- House, block, shop or office
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Getting in touch
Here’s what helps us most when you get in touch:
- Any stains, drips or damp patches you’ve seen indoors
- Your timetable, like an exchange date
- The kind of building and roof involved
- Access details, such as a loft hatch or a shared roof
To arrange a survey, phone 07833 053749 or send us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
What electronic leak detection looks like in Broom Hill
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.7 miles north-west lies Bromley Palace, a reminder of how long the area around Broom Hill has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Broom Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway when you book. Take an older house close to Church of All Saints: flat-roofed rear additions and dormers added over the years are worth checking.
Broom Hill is about 1 mile south-west of Orpington, in Greater London. Broom Hill is one of many places we visit across Greater London, for houses, flats and commercial buildings. Our Greater London coverage includes Broom Hill and the places around it. London is in our area too.
Electronic leak detection in BR6 and BR5 work the same way as everywhere else we cover. We cover properties on New Road, Irene Road and Sandy Lane and the roads around them.

Around Broom Hill

Open spaces near Broom Hill include Summer Hill and The Warren.
How it works
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Surveys in Broom Hill can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Buyers: confirm access with the estate agent or seller
- For a flat or shared roof, check access with the freeholder or managing agent
- Note where any stains or damp appear

FAQs for Broom Hill
Is parking a problem for a survey in Broom Hill?
It depends on the street. If Broom Hill has controlled parking where you are, a visitor permit is the easiest answer.
How do I find out if my home in Broom Hill is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
What if it rains on the day?
Light rain does not typically stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions aren’t right we will arrange another day with you.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
Which method do you use?
We choose the method that suits the roof. You will know which method we plan to use before we start.
How much time does ELD need?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
What this survey can’t tell you
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- The extent of water in the insulation
- Water entering through details rather than the membrane
- Repairing the breaches (that is for your roofer)
If in doubt, call 07833 053749 or drop us an email and we will point you to the right survey. What our survey covers.
