About our electronic leak detection in Turners Hill
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We will say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. Common reasons to book are damage from equipment installers and leaks at pipes, outlets or fixings, on single-ply roofs, commercial flat roofs and roof terraces and balconies.
Older buildings in small places like Turners Hill may be listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Electronic leak detection around Turners Hill
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. About 1.6 miles south-east lies Gravetye Manor, a reminder of how long the area around Turners Hill has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like Turners Hill CofE Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to Church of St Leonard: flat-roofed rear additions and dormers added over the years are worth checking.

Surveys for landlords and agents in Turners Hill
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, so they’re priced to suit.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
What we cannot see
We only report what can be seen safely on the day, so some things are outside what a survey can do:
- Leaks from walls, copings or rooflights
- Fixing the holes we find
- Areas we can’t reach or that cannot be tested
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we will tell you. What our survey covers.
What this survey covers
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Single-ply roofs
What we look for on each type of roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Green and ballasted roofs
Parts of the covering may have to come up. We explain what’s needed when we quote.
How the survey works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we’re there. Older rural homes like those around Turners Hill 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.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Getting ready for the survey
- If you are buying, let the agent know when we are coming
- Leave a clear route to the loft
- Point out any leaks or damp patches
Arrange a survey
To arrange a survey, call 07833 053749 or email us and tell us the address and what’s prompted the survey. You will know the price before anything is booked.

- Leaking laps in the waterproofing

Turners Hill: your questions answered
Is Turners Hill in the area you cover?
Yes. Our area covers London and South East England, and Turners Hill is part of that. You can phone 07833 053749 or email us with the address and some details.
How do I find out if my home in Turners Hill is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. What sits on the membrane affects the method so we check the roof first.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we will explain what’s needed.
What do I do with the report?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Tips that help
There’s plenty you can do without going near the roof. What helps most:
- Limit access to the roof
- Do not leave water getting in
- Note where leaks show inside and when
- Clear flat roof outlets regularly
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
