About our electronic leak detection in Penton Hook
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we will say so. Common reasons to book are holes around roof penetrations and water coming in under a flat roof, on roof terraces and balconies, liquid-applied waterproofing and single-ply roofs.
In a small place like Penton Hook, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
The report records the flat roof membrane as we found it on the day. It’s useful straight away, and a good reference for later, such as when you want to compare after future work.

What affects the cost of electronic leak detection
All our prices include VAT. The things that change the price are:
- How tall the building is and how easy the roof is to see
- Whether thermal imaging or a drone is needed
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the price for your roof before booking.
Getting in touch
If you can, have these to hand when you get in touch:
- The type of building and roof, such as pitched or flat
- The reason for the survey, like buying, a leak or storm damage
- Your postcode, so we can check access and travel
- Pictures from the garden or a window, if you have them
We confirm the price for your roof before you book, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or email us.
Flat roofs in Penton Hook
Within a mile and a half or so of Penton Hook there are several hotels. If you look after one, a leak through a flat roof can put a room out of use. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
For landlords with property near Chertsey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you run a hotel or guest house in or near Penton Hook, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition.

Penton Hook questions
Do you cover smaller places like Penton Hook?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Penton Hook is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
What do I do with the report?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
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 so we can pinpoint it.
Do you climb onto every roof?
Only when it is safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
Does the report include photographs?
Yes. Photographs are part of every report.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
When to book a survey in Penton Hook
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Typical things we are asked to look at include:
- New roofs to check before paving or planting
- Breaches around outlets and penetrations
- Damage from equipment installers
- A flat roof leak that can’t be traced
Take an older house close to Church of All Saints: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before you book any roof surveyor
- Will they check the loft as well as the outside?
- How long the report takes to arrive
- What they will not be able to tell you
- Do they have a CAA Flyer ID and Operator ID for drone work?
How the survey works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. You’re welcome to ask questions while we’re there. Rural addresses near Penton Hook can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- 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.
- You receive the results to pass to your roofer.
Preparing for the visit
- Find any records of previous roof work
- Agree roof access with the managing agent if it is shared
- Note where any stains or damp appear

Advice
Roof by roof
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We look at this first.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.
