About our electronic leak detection in Calvert
There are different ELD methods. Low-voltage methods normally need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We’ll say if your roof doesn’t suit either method before any testing starts. We’re frequently asked to look into damage from equipment installers and repairs that haven’t stopped the leak, on green roofs, roof terraces and balconies and liquid-applied waterproofing.
In a village or hamlet like Calvert, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

What affects the price in Calvert
What a survey costs depends on the time and equipment it needs. The main factors are:
- Any need for thermal images or a drone flight
- Chimneys, valleys, parapets and other details
- The type of building, from a house to a block or an office
- The roof’s overall size
To find out what your survey will cost, ring 07833 053749 or send us an email with the address and some details. We’ll confirm the figure before booking.
Booking your survey
Some details help us point you to the right survey and price. When you contact us, it’s useful to mention:
- What’s prompted the survey
- Pictures from the garden or a window, if you have them
- Where any leaks, stains or damp patches show inside
- Anything about access we should know
We confirm the price for your roof before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or send us an email.
Can I check my roof myself?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
What we cannot see
It is useful to know what a survey won’t do before booking:
- Water entering through details rather than the membrane
- Parts of the roof covered by fixed equipment
- Some conductive membranes
If you’re not sure which survey you need, ring 07833 053749 or drop us an email and we’ll give you a straight answer. What our survey covers.
Roofs we survey in Calvert
- Commercial flat roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
- Green roofs
What we do, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take a time that depends on the roof’s area and construction, which we’ll explain when we quote. Around Calvert, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Leave a clear route to the loft
- Have any questions written down, so nothing gets missed

Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or email us.
Advice
What we look for on each type of roof
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Check new waterproofing before handover
- Don’t let outlets block
- Keep a note of leaks after rain
- Tell us about the membrane and build-up if you know it
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.

Flat and commercial roofs around Calvert
A number of Buckinghamshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Claydon House, about 2.1 miles east, is one of the historic houses in the wider area around Calvert. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church like Church of St Michael are frequently among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Your questions about electronic leak detection in Calvert
Will you come out to Calvert?
Yes, Calvert is covered. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.
How do I find out if my home in Calvert 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.
What do I do with the report?
You’ll receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, and 98% of customers are satisfied.
