What we look for on each type of roof
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
About our electronic leak detection in Crawley
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. 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. The results come in a report with photos. If you are worried about breaches hidden under paving or planting and holes left by work on the roof, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Crawley, 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. If there are outbuildings or garages with flat roofs, mention them when you book.
After the visit, you get a written report with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Checking the roof from the ground
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
What electronic leak detection looks like in Crawley
Thatch survives on some older buildings in Hampshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Before planning roof work on an older home, find out whether it is listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you own a rental within reach of Winchester station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If your house is among the older ones in the streets near Church of St Mary, the flat roofs on later extensions tend to wear out long before the main roof.
Crawley is about 5 miles north-west of Winchester, in Hampshire. Whether the building in Crawley is a house, a flat or a commercial unit, we can survey the roof. Across Hampshire, we cover Crawley and the places around it. Our Southampton page covers surveys nearby.

Questions from Crawley
Do you cover Crawley?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will you come out to Crawley?
Yes, Crawley is on our map. Villages and rural addresses get the same survey as a town house.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Do you look in the loft space?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
Is this a RICS survey?
No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
The survey, step by step
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Cottages and farmhouses around Crawley often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- Note where any stains or damp appear
- Check pets are kept safely away
- If you’re buying, let the agent know when we are coming
Booking a survey
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or send us an email.
Advice
Landlord and commercial surveys in Crawley
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on any day of the week, which can make access easier.
What electronic leak detection doesn’t cover
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Areas we cannot reach or that can’t be tested
- Repairing the breaches (that is for your roofer)
- The extent of water in the insulation
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer before booking. What a survey covers and does not.
Roof types and parts we check
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Roof terraces and balconies
- Single-ply roofs
Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. Outbuildings and barns around Crawley are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
