Signs you need electronic leak detection in Chorleywood West
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Common reasons to book include:
- New membranes needing a check before handover
- Leaks under green or ballasted roofs
- Gaps at membrane joints
- Holes left by work on the roof
Take a building like Arnett Hills Junior Mixed and Infant School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Chorleywood West: what you get
There are different ELD methods. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. We will say if your roof does not suit either method at the outset. If you’ve noticed damp inside with no sign on the roof and leaks under green or ballasted roofs, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Chorleywood West may be listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. You will see the good as well as the bad.

Chorleywood West questions

How do I find out if my home in Chorleywood West is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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.

How long have you been surveying roofs?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Will I get photos?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
Electronic leak detection around Chorleywood West
Historic houses like Chenies Manor House, about 2.8 miles north-west, show how far back building in the area around Chorleywood West goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
The streets around a church like Church of St Peter are frequently among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you run a business near Charter Place, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
How it works
Every roof is different; as a rough guide, the survey takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. If you have questions on the day, just ask. In a hamlet or village like Chorleywood West, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Getting ready for the survey
- Tell us where we can park nearby
- Make sure we can get to the back of the property
- Have any questions written down, so nothing gets missed

Prices for electronic leak detection in Chorleywood West
Several things affect the price of a survey:
- Chimneys, valleys, parapets and other details
- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
Getting in touch
To price your survey accurately, we’ll ask about:
- How the loft is reached, if there is one
- The property’s address and postcode
- Photos of the roof, taken safely from ground level or a window
- Any marks or damp showing indoors
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or use the contact form.
