What we look for on each type of roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Electronic leak detection for homes and businesses in Handcross
ELD can be carried out in more than one way. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We’ll say if your roof does not suit either method at the outset. If you’ve noticed failed seams and laps and new membranes needing a check before handover, a survey will tell you what’s going on, on commercial flat roofs, liquid-applied waterproofing and flat roof membranes alike.
In a small place like Handcross, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Roofs whose membrane or build-up is not suitable
- Water entering through details rather than the membrane
- Areas we cannot reach or that can’t be tested

What this survey covers
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
- Liquid-applied waterproofing
- Green roofs
- Single-ply roofs
Practical tips
A survey works best with a little help from you, before and after. Tips:
- Act on new leaks promptly
- Do not keep patching the same spot
- Limit access to the roof
- Check trades protect the waterproofing
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Handcross: your questions answered
Do you cover Handcross?
Yes, Handcross is one of the places we work. The survey and report are the same in Handcross as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Handcross?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
How long does electronic leak detection take?
Testing typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
What do I do with the report?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you look in the loft space?
If there is a loft and safe access to it, yes. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
Why act early in Handcross
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. In a place like Handcross, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

How it works
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Around Handcross, older homes can have small or awkward roof spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- Have any paperwork from past roof work to hand
- If you are buying, check with the agent that we can get in

Flat roofs in Handcross
About 1.9 miles south-east lies Tyes Place, a reminder of how long the area around Handcross has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your home is one of the older ones in the streets near All Saints, the joins between later flat roofs and the old walls are where problems usually start. If you own a rental within reach of Balcombe station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Handcross Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
