Electronic leak detection in New Eltham: what you get
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help, 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 liquid-applied waterproofing, and people most often book us about leaks showing away from the breach and new roofs to check before paving or planting.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in New Eltham, the roof above may belong to the building rather than one flat.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, with the construction of the roof playing a part too. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in New Eltham runs like any other.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Have any questions written down, so nothing gets missed
- Keep pets out of the way during the survey
- Make sure the loft hatch can be reached

Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where applicable.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
What we can’t see
We only report what can safely be seen on the day, so there are some things a survey cannot cover:
- Sections we can’t safely access
- Leaks from walls, copings or rooflights
- Roofs whose membrane or build-up isn’t suitable

Useful tips for New Eltham property owners
Over many surveys, some simple habits stand out as worth the effort:
- Check new waterproofing before handover
- Use boards when working on the roof
- Stay off the flat roof unless needed
- Clear flat roof outlets regularly
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.

Common roof problems in New Eltham
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
People typically book a survey after spotting something like this:
- Leaks through a covered membrane
- Punctures from foot traffic or tools
- Water coming in under a flat roof
- New membranes needing a check before handover
Take a building like Wyborne Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

New Eltham: your questions answered
Does a conservation area affect roof work in New Eltham?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you carry out roof surveys in New Eltham?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
What happens after the survey?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Will you walk on the roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
