Dean Electronic Leak Detection
Electronic leak detection in Dean from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us.
- Gaps at membrane joints
- Water coming in under a flat roof
- Holes left by work on the roof
What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Electronic leak detection in Dean: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. If you’ve noticed new membranes needing a check before handover and breaches hidden under paving or planting, a survey will tell you what’s going on.
Older buildings in small places like Dean may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. 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.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Commercial roofs and larger buildings
- Chimneys, valleys, parapets and other details
- The roof’s overall size
- Any need for thermal images or a drone flight
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
What we need to know
We’ll typically ask about:
- Pictures from the garden or a window, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
- The kind of building and roof involved
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 use the contact form whenever suits you.
Electronic leak detection around Dean
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Landlords with a home close to Botley station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like Bishops Waltham Infant School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Questions from Dean
How do I find out if my home in Dean is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Will you come out to Dean?
We do. A small place gets exactly the same survey as a big one.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. We look at the parts we’re given access to.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
What is electronic leak detection?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.

What else we do in Dean
Do you need electronic leak detection in Dean?
Holes in a membrane often come from feet, tools or debris. Many are tiny but water still finds them.
Most people get in touch when they’ve noticed one of these:
- Holes around roof penetrations
- A flat roof leak that can’t be traced
- Holes left by work on the roof
- Leaks showing away from the breach
If your house is among the older ones in the streets near Church of St Peter, the joins between later flat roofs and the old walls are where problems usually start.
Before booking anyone
- When you’ll get the report
- Whether any drone flown is registered with the CAA
- Whether VAT is in the quoted price
- Whether the roof space is looked at, where there is one
How the survey changes by roof type
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Landlords, agents and block managers in Dean
Letting agents can arrange access with tenants. Surveys run seven days a week, which helps when tenants work during the week.
We survey roofs for letting agents and landlords as well as householders. A report with photos gives you a clear record of the flat roof membrane, useful for planning maintenance.
The survey, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Dean 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 agree the area to be tested.
- 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.
Before we arrive
- Jot down any questions you want answered
- Keep pets out of the way during the survey
- Leave side gates unlocked
