Useful tips for Chilworth property owners
Here are a few things we’d tell any owner, before and after a survey:
- Check trades protect the waterproofing
- Find the breach before more patching
- Consider ELD before paving or planting goes on
- Act on new leaks promptly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
Electronic leak detection in Chilworth
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. It is testing only and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. We are often asked to look into leaks under green or ballasted roofs and damage from equipment installers, across liquid-applied waterproofing, green roofs and flat roof membranes.
Flat roofs on exposed homes in small places like Chilworth take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets. You will see the good as well as the bad.

What we’re asked to look at in Chilworth
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
Here are some of the things we see frequently:
- Gaps at membrane joints
- Stains far from any visible defect
- A flat roof leak that cannot be traced
- Patched roofs that still leak
The streets around a church such as Church of St Thomas are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.

Your questions about electronic leak detection in Chilworth
Do you cover Chilworth?
Yes. We survey roofs across London and South East England, and Chilworth is part of that. You can ring 07833 053749 or send us an email with the address and some details.
How do I find out if my home in Chilworth is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Tell us what you know about the roof and we’ll check whether ELD will work.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather is not right.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
The survey, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Chilworth can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Let us know about parking near the property
- For a flat or shared roof, check access with the building owner or managing agent
- Leave side gates unlocked
