Electronic Leak Detection in Birchgrove
Wondering about the flat roof membrane at a property in Birchgrove? We carry out electronic leak detection in Birchgrove and across West Sussex, with plain-English findings.
- New membranes needing a check before handover
- Water coming in under a flat roof
- Holes around roof penetrations
Useful tips for Birchgrove property owners
Over many surveys, some simple habits stand out:
- Clear flat roof outlets regularly
- Keep a note of leaks after rain
- Ask contractors to protect the membrane
- Test new membranes before covering them
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Electronic leak detection for homes and businesses in Birchgrove
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an 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 can repair them. You get a report with photos of each breach found. If you are worried about breaches hidden under paving or planting and damage from equipment installers, we can find out what’s behind it, whatever the roof.
Somewhere as small as Birchgrove, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What happens on the day
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where applicable. Most surveys take a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Older roofs in small places like Birchgrove can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before the survey
- Unlock side gates and any roof access doors
- If you are buying, let the agent know when we’re coming
- Jot down any questions you want answered

FAQs for Birchgrove
How do I find out if my home in Birchgrove is listed?
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.
Do you cover smaller places like Birchgrove?
Yes, Birchgrove is covered. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What if it rains on the day?
Light rain is usually fine; heavy rain and wind are different. In strong wind or heavy rain, a drone can’t fly and access may not be safe, and we’d agree another day.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
Will you check the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
Landlord and commercial surveys in Birchgrove
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
Flat roofs in Birchgrove
Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Priest House, about 2.9 miles north-west, show how far back building in the area around Birchgrove goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
For an older house near a landmark such as Chelwood Gate Church, the joins between later flat roofs and the old walls are where problems usually start.

Prices for electronic leak detection in Birchgrove
Prices always include VAT. What changes the price is:
- Features like valleys, chimneys, dormers and parapets
- The roof’s overall size
- Whether thermal imaging or a drone is needed
- How many separate roofs there are, like extensions, dormers and garages
What a survey costs comes down to the roof itself: 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.
Helping us price your survey
There’s no need for technical words. Just let us know:
- The kind of building and roof involved
- The address and postcode of the property
- The reason for the survey, such as buying, a leak or storm damage
- Where any leaks, stains or damp patches show inside
Photos help, if you have them. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or send us an email.
Checking the roof from ground level
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Roof by roof
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
