How electronic leak detection works in Forestdale
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that can’t give results. If you’ve noticed waterproofing to test before it’s covered and punctures from foot traffic or tools, a survey will tell you what’s going on.
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 Forestdale, the flat roof is often a shared part of the building.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t.

Landlord and commercial surveys in Forestdale
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.

Local flat roofs in Forestdale
The wider area around Forestdale has a long history of building, with Addington Palace about 0.9 miles north. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you live in an older home near St Francis, the flat roofs on later extensions tend to wear out long before the main roof. As a London address, Forestdale can be tricky for parking: a visitor permit or a nearby bay makes the day easier. If you own a rental within reach of Sanderstead station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

How the survey works
Once we have finished looking, we write up our findings as a photo-illustrated written report, emailed to you. On timing, it usually takes a length of time set by the membrane area and the build-up, which we set out in the quote. Surveys in Forestdale can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Keep pets in another room
- Point out any leaks or damp patches
- Let us know about parking before the day

Advice
What affects the price in Forestdale
When we price a survey, we consider:
- Any need for thermal images or a drone flight
- House, block, shop or office
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.
Getting in touch
Before you get in touch, it helps to have:
- Whether there is a loft hatch, a shared roof or tricky access
- Why you want a survey: buying, a leak, a storm or new work
- Your timetable, like an exchange date
- Where any leaks, stains or damp patches show inside
Getting a price is simple: just call 07833 053749 or drop us an email and give us some details about the property and we will recommend the right survey. The price is agreed up front.
What electronic leak detection does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Fixing the holes we find
- Leaks from plumbing or windows
- How wet the insulation is

Questions from Forestdale
Is parking a problem for a survey in Forestdale?
Parking in Forestdale, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Does a conservation area affect roof work in Forestdale?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Will you go up on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
Can you inspect my roof with a drone?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Will you check the loft?
Where it is relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
Different roofs, different checks
Bituminous membranes
ELD is often possible on bituminous membranes though the layers below matter.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Checking the roof from ground level
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.
