Electronic Leak Detection in Alfold
Electronic leak detection to pinpoint holes in flat roof membranes for Alfold, from an experienced roof surveyor. You get a clear written report with photographs.
- New membranes needing a check before handover
- Leaking laps in the waterproofing
- Leaks through a covered membrane
How it works
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can safely be seen, from the ground, from windows, in the loft space and by drone where applicable. Most surveys take as long as needed for the membrane area and the build-up, which we set out in the quote. Somewhere as small as Alfold, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Jot down any questions you want answered
- If you’re buying, let the agent know when we are coming
- Gather any invoices or paperwork from past roof work
Booking a survey
If you’re buying, it is useful to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or send us an email whenever suits you.

Electronic leak detection in Alfold: what you get
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs are not part of the report; that is for your roofer to price. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. Common reasons to book are damp inside with no sign on the roof and leaks that return after repairs, on roof terraces and balconies, commercial flat roofs and single-ply roofs.
Older buildings in small places like Alfold 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. Listed building consent is needed for changes that affect a listed building’s special interest.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Alfold questions
Is Alfold within the area you cover?
Yes. Alfold is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Do you cover Alfold?
Yes, Alfold is one of the places we work. Every survey there gets the same written report with photographs.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we’ll recommend one.
Does the weather affect the survey?
Light rain does not normally stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we’ll arrange another day with you.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
How quickly is the report sent?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
What we are asked to look at in Alfold
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
A survey makes sense if you’ve noticed:
- Repairs that haven’t stopped the leak
- Breaches hidden under paving or planting
- Gaps at membrane joints
- Holes around roof penetrations
Whatever the street in Alfold, a roof costs least to look after when faults are caught early.
Before you book any roof surveyor
- What experience they bring
- Whether the price includes VAT
- What’s outside the scope of the survey
- How they plan to inspect the roof safely
Practical tips
A little preparation and a few simple habits help. Some pointers:
- Share any drawings of the roof
- Get leaks traced quickly
- Do not let outlets block
- Keep foot traffic on flat roofs to a minimum
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
How we price electronic leak detection
Prices always include VAT. The things that change the price are:
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What we need to know
What helps most when you contact us:
- How the loft is reached, if there is one
- Any deadline, like an exchange date
- The property’s address and postcode
- Where water is showing inside, if it is
Photos help, if you have them. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To send them or to book, call 07833 053749 or email us.
Electronic leak detection around Alfold
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to Church of St Nicholas: the joins between later flat roofs and the old walls are where problems usually start.
