Why it’s worth a survey now in High Leigh
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.

Electronic leak detection in High Leigh
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a report with photos of each breach found. Typical surveys look at repairs that haven’t stopped the leak and new roofs to check before paving or planting, on flat roof membranes, commercial flat roofs and roof terraces and balconies.
In a village or hamlet like High Leigh, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included as you book.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

What we look for on each type of roof
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We will tell you if yours is not suitable.
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Before and after the survey
You do not need to be a roofer to help. What helps most:
- Consider ELD before paving or planting goes on
- Don’t leave water getting in
- Do not let outlets block
- Check trades protect the waterproofing
If anything in the report is not clear, ask us. We can talk you through the findings.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Do you need electronic leak detection in High Leigh?
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
A survey makes sense if you’ve noticed:
- Failed seams and laps
- Holes left by work on the roof
- Damp inside with no sign on the roof
- New membranes needing a check before handover
If you look after a building such as Westfield Community Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

High Leigh questions
Do you cover smaller places like High Leigh?
Yes. High Leigh is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does a conservation area affect roof work in High Leigh?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
Will you check the loft?
Usually, if there’s one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Are you insured?
We hold professional indemnity and public liability insurance.
Flat and commercial roofs around High Leigh
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Before planning roof work on an older home, find out whether it is listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
For landlords with property near Broxbourne station, the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church such as Church of St Catherine & St Paul are often among the oldest in a place, and if yours is one of the older homes nearby, the flat roofs on later extensions tend to wear out long before the main roof.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How it works
There isn’t much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there.

Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
