Electronic leak detection for homes and businesses in Wych Cross
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we will say so. 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. You’ll also know what to check next. Typical surveys look at waterproofing to test before it’s covered and breaches around outlets and penetrations, across green roofs, roof terraces and balconies and commercial flat roofs.
Flat roofs on exposed homes in small places like Wych Cross take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
The report is written in plain words, so you do not need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

What affects the price in Wych Cross
To price your survey, we check:
- The height of the building and how the roof can safely be seen
- The roof’s overall size
- Extensions, dormers and garages with roofs of their own
- House, block, shop or office
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
What we need to know
A few details help us point you to the right survey and price. When you get in touch, it helps to mention:
- Any stains, drips or damp patches you’ve seen indoors
- What’s prompted the survey
- The address and postcode of the property
- Whether there is a loft hatch, a shared roof or tricky access
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 send them or to book, ring 07833 053749 or use the contact form.
Should I look at the roof myself first?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
What happens on the day
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photographs go into the written report. It usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Wych Cross often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Gather any invoices or paperwork from past roof work
- Check the loft hatch can be reached
- Buyers: confirm access with the estate agent or seller

Advice
Flat roofs in Wych Cross
The wider area around Wych Cross has a long history of building, with Standen about 3.2 miles north-west. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For site and facilities teams at buildings such as Greenfields School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of East Grinstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Note where leaks show inside and when
- Make sure trades protect the waterproofing
- Avoid repeated repairs without finding the cause
- Let us know about the membrane and build-up if you know it
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.

Why it’s worth a survey now in Wych Cross

Common questions in Wych Cross
Is Wych Cross within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
How do I find out if my home in Wych Cross is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
What happens after the survey?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How long does electronic leak detection take?
Testing usually takes as long as needed for the roof’s area and construction, which we set out in the quote.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Is my roof suitable for ELD?
ELD does not suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. We will tell you if yours is not suitable at the start.
