Electronic Leak Detection in Upper Ruxley
Find out what’s going on with the flat roof membrane before you spend money on it. Electronic leak detection in Upper Ruxley, with photographs and a clear written report.
- Damp inside with no sign on the roof
- Waterproofing to test before it’s covered
- Gaps at membrane joints
How the survey works
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof cannot be seen, the report says so. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. London terraces rarely offer a view of the whole roof from one spot, so in Upper Ruxley we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- 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.
How to prepare
- Make sure the loft hatch can be reached
- Mention any parking restrictions on your street
- If you are buying, let the agent know when we’re coming

About our electronic leak detection in Upper Ruxley
Green roofs, ballasted roofs and roofs under paving are harder to test. 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 is not possible, we’ll say so. We survey green roofs, flat roof membranes and single-ply roofs, and common reasons people get in touch are a flat roof leak that can’t be traced and waterproofing to test before it’s covered.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Upper Ruxley, the flat roof is often a shared part of the building.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put by urgency where it matters.

Your questions about electronic leak detection in Upper Ruxley
Is my home in Upper Ruxley listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Upper Ruxley?
Yes, Upper Ruxley is one of the places we work. The survey and report are the same in Upper Ruxley as anywhere else.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
How long does electronic leak detection take?
Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so the building owner or managing agent needs to agree access. We can only inspect what we are given access to.
What’s the best way to book?
To arrange a survey, phone 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps when budgeting.
Letting agents can arrange access with tenants, at a time agreed in advance. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
What affects the price in Upper Ruxley
A few things affect what a survey costs:
- Extra roofs, like extensions, dormers or garages
- How complicated the roof is, with its valleys, chimneys and parapets
- Any need for thermal images or a drone flight
- The size of the roof
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your roof before booking.

Useful tips for Upper Ruxley property owners
A survey works best with a little help from you, before and after. Some tips:
- Act on new leaks promptly
- Ask contractors to protect the membrane
- Stay off the flat roof unless needed
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Common roof problems in Upper Ruxley
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
Signs worth acting on include:
- Repairs that haven’t stopped the leak
- Holes around roof penetrations
- New membranes needing a check before handover
- Leaks showing away from the breach
Landlords with a home close to Swanley station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Flat roofs in Upper Ruxley
With Hall Place and Gardens about 2.7 miles north, Upper Ruxley sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. 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. If your home in Upper Ruxley is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you look after a building such as Hope Community School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
