Electronic leak detection in North Heath, West Sussex
Electronic leak detection to pinpoint holes in flat roof membranes around North Heath, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Gaps at membrane joints
- New membranes needing a check before handover
- Leaks at pipes, outlets or fixings
The survey, step by step
Time on site depends on the size and shape of the roof, but 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. Somewhere as small as North Heath, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- 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.
How to prepare
- Leave a clear route to the loft
- Check pets are kept safely away
- Show us where any leaks or stains appear
Booking a survey
Photos help, if you have them. Take them safely from the ground or a window, and please do not climb up for a closer look. To get started, ring 07833 053749 or drop us an email.

How electronic leak detection works in North Heath
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. Typical surveys look at leaking laps in the waterproofing and new roofs to check before paving or planting, on liquid-applied waterproofing, commercial flat roofs and roof terraces and balconies.
In a village or hamlet like North Heath, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: 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 when booking.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

What we look for on each type of roof
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
What affects the price in North Heath
Prices always include VAT. What changes the price is:
- Commercial roofs and larger buildings
- The size of the roof
- Features like valleys, chimneys, dormers and parapets
- The height of the building and how the roof can safely be seen
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What to let us know when you contact us
Here’s what helps us most when you get in touch:
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
- The kind of building and roof involved
- Photos of the roof, taken safely from the ground or a window
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you are ready.
FAQs for North Heath
Do you cover North Heath?
We do. The survey and report are the same in North Heath as anywhere else.
Do you cover smaller places like North Heath?
Yes, North Heath is covered. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Do I have to be there for the survey?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.
Is my roof suitable for ELD?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We will tell you if yours is not suitable before testing.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so whoever owns or manages the building needs to agree access. We can only inspect what we’re given access to.

Electronic leak detection around North Heath
Many older homes in Sussex have handmade clay tiles and tile-hung 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. Historic houses such as Old Place Manor, about 2.1 miles south-west, show how far back building in the area around North Heath goes. 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.
If you let a flat or house near Pulborough station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Why get it checked now?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Older cottages and farmhouses around North Heath can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.

Checking the roof from the ground
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that is for your roofer)
- How wet the insulation is
