Electronic leak detection for homes and businesses in Marsworth
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a photo-illustrated written report. Common reasons to book are failed seams and laps and punctures from foot traffic or tools, across single-ply roofs, commercial flat roofs and roof terraces and balconies.
In a village or hamlet like Marsworth, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

What a survey costs
Several things affect the price of a survey:
- Chimneys, valleys, parapets and other details
- How many separate roofs there are, like extensions, dormers and garages
- House, block, shop or office
- Building height and the viewpoints available
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Getting in touch
To price your survey accurately, we’ll ask about:
- Where water is showing inside, if it is
- The reason for the survey, like buying, a leak or storm damage
- Photos of the roof, taken safely from the ground or a window
- What kind of property and roof it is
To arrange a survey, ring 07833 053749 or email us with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.

Common questions in Marsworth
Does a conservation area affect roof work in Marsworth?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Marsworth within the area you cover?
Yes, Marsworth is covered. We survey roofs across London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Can you survey at the weekend?
We carry out surveys on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or email us.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Electronic leak detection around Marsworth
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Cholesbury Manor House, about 4.6 miles south, is one of the historic houses in the wider area around Marsworth. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
For landlords with property near Tring station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If your home is one of the older ones in the streets near Church of All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What this survey cannot tell you

- Leaks from walls, copings or rooflights
- Build-ups without a suitable layer below
- Fixing the holes we find
If in doubt, phone 07833 053749 or drop us an email and we’ll point you to the right survey before you book. What our survey covers.
Roofs we survey in Marsworth
- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
Common roof problems in Marsworth
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
Problems we come across frequently include:
- Leaks through a flat roof with no obvious cause
- Breaches around outlets and penetrations
- Patched roofs that still leak
- Leaks showing away from the breach
If you look after a building such as Marsworth Church of England Infant School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book anyone
- Whether VAT is in the quoted price
- Will the report include photos?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether they hold professional indemnity and public liability insurance
How it works
Once we have finished looking, we write up our findings as a written report with photos, emailed to you. As for time on site, it normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Marsworth can have low, tight loft spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Keep pets out of the way during the survey
- Note where any stains or damp appear
- Mention any parking restrictions on your street
Getting a price
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or send us an email whenever suits you.
Related advice
How the survey changes by roof type
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will tell you if yours is not suitable.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Tips that help
A survey works best with a little help from you, before and after. Tips:
- Stay off the flat roof unless needed
- Have roof specifications to hand
- Get leaks traced quickly
- Keep outlets clear of debris
If anything in the report isn’t clear, ask us. We can talk you through the findings.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
