What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. We test where the roof suits it.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
About our electronic leak detection in River
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you’ve noticed waterproofing to test before it’s covered and failed seams and laps, a survey will tell you what’s going on, on green roofs, single-ply roofs and roof terraces and balconies alike.
Somewhere as small as River, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included when booking.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

What affects the price in River
To price your survey, we check:
- The number of roofs, including extensions and garages
- How complicated the roof is, with its valleys, chimneys and parapets
- House, block, shop or office
- Any need for thermal images or a drone flight
To find out what your survey will cost, call 07833 053749 or use the contact form with the address and a few details. We’ll confirm the figure before booking.
Booking your survey
A few details help us suggest the right survey and price. When you contact us, tell us:
- Where the property is, with the postcode
- Where water is showing inside, if it is
- Dates you are working to, such as exchange
- The kind of building and roof involved
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.
What we do, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and make notes for the report. It normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like River can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- If it is not your property yet, arrange access through the agent
- Keep pets out of the way during the survey
- Have any questions written down, so nothing gets missed
How to book

Your questions about electronic leak detection in River
Is my home in River listed or in a conservation area?
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.
Do you carry out roof surveys in River?
Yes. We survey roofs across London and South East England, and River is part of that. You can phone 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
What electronic leak detection looks like in River
Petworth House, about 2.4 miles east, is one of the historic houses in the wider area around River. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. 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.
The streets around a church such as The Parish Church of St Peter are frequently among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
River is about 12 miles east of Petersfield, in West Sussex. River is one of many places we visit across West Sussex, for houses, flats and commercial buildings. Our West Sussex coverage includes River and the places around it. We also survey roofs in Guildford.
We survey roofs across the GU28 postcode area for electronic leak detection and the streets around it. Close by, we survey roofs in Upperton (1 mile east), Selham (2 miles south), Tillington (2 miles south-east), South Ambersham (2 miles south-west) and Hampers Green (2 miles east). Further out, we also cover Bognor Regis (14 miles south), Chichester (12 miles south-west), Littlehampton (14 miles south-east), Rustington (15 miles south-east), Storrington (11 miles south-east) and Billingshurst (9 miles east).

For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, ring 07833 053749 or email us with the addresses.

Why get it checked now?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Older cottages and farmhouses around River can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
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.
