Sandwich Electronic Leak Detection
Electronic leak detection in Sandwich, with over 20 years’ experience behind it. You get a clear report with photographs.
- Damage from equipment installers
- Holes around roof penetrations
- Failed seams and laps
How it works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. With a bit of garden around a house, as there frequently is around Sandwich, the roof can be viewed from several angles. Mention any side of the property we cannot get to. Inside, the loft is looked at where it can be reached safely.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- If it is not your property yet, arrange access through the agent
- Point out any leaks or damp patches
- Agree roof access with the managing agent if it’s shared

About our electronic leak detection in Sandwich
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. We survey liquid-applied waterproofing, single-ply roofs and green roofs, and common reasons people get in touch are waterproofing to test before it’s covered and breaches around outlets and penetrations.
Flat roofs in smaller places like Sandwich can be more exposed, especially where nothing shelters them, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away. A flat roof that still holds water days after rain is also worth a closer look.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put in order of urgency where relevant.

FAQs for Sandwich
Does being near the coast affect roofs in Sandwich?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
Is my home in Sandwich listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
How do you choose the testing method?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we’ll agree the details when booking.

What else we do in Sandwich
Flat roofs in Sandwich
Sandwich lies within about 3 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If yours is one of the older homes in the streets near Sandwich United Reformed Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For hotels and guest houses around Sandwich, a roof problem found early is far less disruptive than one found by a guest.

- Leaks through a flat roof with no obvious cause

- Holes around roof penetrations
- Damp inside with no sign on the roof

Before you book any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Whether VAT is in the quoted price
- How soon the report will arrive
- Is there a chance to talk the report through?
For landlords and managing agents
Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you contact us and we’ll plan the visit with that in mind.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
What we look for on each type of roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers, depending on the build-up.
What affects the cost of electronic leak detection
Several things affect the price of a survey:
- The roof’s overall size
- Any need for thermal images or a drone flight
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
For a price for your roof in Sandwich, call 07833 053749 or email us and tell us about the roof. The price is agreed before a date is set.
Booking your survey
If you can, have these to hand when you get in touch:
- Pictures from the garden or a window, if you have them
- Your postcode, so we can check access and travel
- What’s prompted the survey
- Anything about access we should know
We confirm the price for your survey 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. For a price for your roof, call 07833 053749 or drop us an email.
What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
