Electronic leak detection in Harpsden: local notes
Greys Court, about 2.8 miles north-west, is one of the historic houses in the wider area around Harpsden. 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, and any change of roofing material on a listed home needs checking with the council first. Within a mile and a half or so of Harpsden there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If your house is among the older ones in the streets near Church of St Margaret, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you look after a building such as Trinity Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Harpsden
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. We’ll point you to the likely next step. If you’ve noticed damage from equipment installers and new roofs to check before paving or planting, a survey will tell you what’s going on, whatever the roof.
Older buildings in small places like Harpsden 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. Finding out what state the roof is in gives you the facts to plan with. 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 plan your next steps.

Harpsden questions
Is Harpsden within the area you cover?
Yes, Harpsden is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you look at commercial flat roofs near Harpsden, such as hotels?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Which method do you use?
The roof decides the method. We will explain why when we quote.
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. Each one is emailed.
How much does electronic leak detection cost?
We quote for each roof individually. Tell us about the roof and where it leaks, and ring 07833 053749 or use the contact form for a quote.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Do you need to get into the loft?
If there is a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
The survey, step by step
After the inspection, everything we found is written up as a written report with photos, emailed to you. On timing, most surveys take as long as needed for the roof’s area and construction, which we set out in the quote. Somewhere as small as Harpsden, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Mention any parking restrictions on your street
- Agree roof access with the managing agent if it’s shared
- Show us where any leaks or stains appear
Getting a price
Most bookings start with a short call: ring 07833 053749 or drop us an email. You’ll have a price before anything is arranged.

Leave it or get it looked at?
Some breaches are too small to see. ELD picks up breaches a visual check might miss where the roof suits it. In a place like Harpsden, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.

What a survey costs
We confirm the price for your roof before booking. This is what makes a difference:
- Height and safe access
- The roof’s overall size
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.
Booking your survey
Here’s what helps us most when you contact us:
- Where the property is, with the postcode
- The type of building and roof, such as pitched or flat
- Your timetable, such as an exchange date
- How the loft is reached, if there is one
Booking is simple: just phone 07833 053749 or use the contact form, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.
What we are asked to look at in Harpsden
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Look out for signs like these:
- Patched roofs that still leak
- Leaks through a covered membrane
- Holes around roof penetrations
- New membranes needing a check before handover
Landlords with a home close to Henley-On-Thames station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- Their drone registration, if they fly one
- What happens after the report arrives
- What the report includes, and whether it has photographs
- Are they insured for the work?
Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Test new membranes before covering them
- Use boards when working on the roof
- Do not keep patching the same spot
- Keep a note of leaks after rain
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
