Electronic leak detection in Benson
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We survey single-ply roofs, flat roof membranes and roof terraces and balconies, and the problems we’re asked to look at most are repairs that haven’t stopped the leak and breaches hidden under paving or planting.
Around Benson, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It’s worth mentioning them as you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Being in a smaller place like Benson does not change how the visit works: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- 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.
Before the survey
- Have any questions written down, so nothing gets missed
- Let us know about parking before the day
- Keep pets out of the way during the survey

Questions from Benson
Do you cover Benson?
Yes, Benson is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or drop us an email with the address and some details.
Is my home in Benson listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put in order of urgency where relevant.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
Is it a structural engineer’s report?
No. We point out what can be seen, like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or drop us an email.
How much time does ELD need?
It usually takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting.
What electronic leak detection doesn’t cover
Some things cannot be seen without opening up the roof, so a survey has limits:
- Fixing the holes we find
- Roofs whose membrane or build-up isn’t suitable
- Moisture spread under the membrane
If you’re not sure which survey you need, call 07833 053749 or send us an email and we’ll give you a straight answer. What a survey covers and does not.
What this survey covers
- Flat roof membranes
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
Common roof problems in Benson
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
Common reasons to book include:
- Punctures from foot traffic or tools
- Leaks through a covered membrane
- Leaks that return after repairs
- Waterproofing to test before it’s covered
The streets around a church such as Church of St Helen are frequently among the oldest in a place, and if your home is one of the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof.
Choosing a roof surveyor
- Will they check the loft as well as the outside?
- Which parts of the roof they’ll actually see
- Whether VAT is added on top
- What experience they bring
Electronic leak detection around Benson
Brightwell Manor, about 2.7 miles west, is one of the historic houses in the wider area around Benson. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you own a rental within reach of Cholsey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as Benson Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Why get it checked now?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Tradespeople may need to travel further to a smaller place like Benson, so it’s useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Read how roof surveys are priced and what we found on two real jobs.
How we price electronic leak detection
We confirm the exact price before booking. These are the things that affect it:
- The shape of the roof and its details
- The roof’s overall size
- Any need for thermal images or a drone flight
- How tall the building is and how easy the roof is to see
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Helping us price your survey
A little information up front helps. Please include:
- Where water is showing inside, if it is
- Where the property is, with the postcode
- What kind of property and roof it is
- Access details, such as a loft hatch or a shared roof
We survey roofs on any day of the week. To find a date that works for you, ring 07833 053749 or use the contact form.
Before and after the survey
From years of surveys, a few habits stand out:
- Keep a note of leaks after rain
- Share any drawings of the roof
- Make sure trades protect the waterproofing
- Get leaks traced quickly
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
