Electronic leak detection for homes and businesses in Crofton
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. The results come in a report with photos. We survey single-ply roofs, flat roof membranes and commercial flat roofs, and people most frequently book us about a flat roof leak that can’t be traced and breaches around outlets and penetrations.
Older buildings in small places like Crofton may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
After the visit, you get a photo-illustrated written report, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Practical tips
Most of what helps is simple and safe from ground level. Our suggestions:
- Consider ELD before paving or planting goes on
- Ask contractors to protect the membrane
- Have roof specifications to hand
- Keep a note of leaks after rain
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
Check contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.
How we price electronic leak detection
When we price a survey, we consider:
- The height of the building and how the roof can safely be seen
- The use of thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- Features like valleys, chimneys, dormers and parapets
For a price for your roof in Crofton, ring 07833 053749 or send us an email with the address and some details. The price is agreed before a date is set.
What to tell us when you contact us
We’ll typically ask about:
- What kind of property and roof it is
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.
How the survey changes by roof type
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Electronic leak detection around Crofton
Crofton lies within about 2 miles of the sea, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Some Hampshire villages still have thatched roofs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings such as Crofton School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you own a rental within reach of Fareham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a shop, office or commercial unit, for example near Fareham Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Crofton is about 1 mile east of Stubbington, in Hampshire. Whether the building in Crofton is a house, a flat or a commercial unit, we can survey the roof on a weekday or at the weekend. Crofton is one of the towns and villages in Hampshire where we work.

Your questions about electronic leak detection in Crofton
Does being near the coast affect roofs in Crofton?
Yes, coastal weather is harder on roofs: there is more wind, and more salt in the air. Exposed details like ridges, verges, flashings and metal fixings are the ones to watch.
How do I find out if my home in Crofton 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.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Will you go up on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
DIY checks: what’s safe
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, and those are details a survey looks at closely.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.

What happens on the day
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey usually takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Older roofs in small places like Crofton can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- 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.
Getting ready for the survey
- Let us know about parking before the day
- For a flat or shared roof, check access with the building owner or managing agent
- Tell us about any leaks, stains or damp patches you know of

Honest limits
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Water entering through details rather than the membrane
- Fixing the holes we find
- Some conductive membranes
