Electronic leak detection for homes and businesses in Warlingham
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It saves a wasted visit. If you are worried about gaps at membrane joints and leaks that return after repairs, we can find out what’s behind it, on commercial flat roofs, green roofs and roof terraces and balconies alike.
In smaller places like Warlingham, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it. Ponding, splits and lifting edges are the signs to look for from a window.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later, such as when you want to compare after future work.

What we do, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a smaller place like Warlingham, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Agree roof access with the managing agent if it’s shared
- Make sure pets are kept safely away
- Leave a clear route to the loft
Arrange a survey
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email, and we will ask about the building and what you need. The price is agreed before a date is set.

Electronic leak detection around Warlingham
About 3.5 miles north lies Addington Palace, a reminder of how long the area around Warlingham has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you let a flat or house near Upper Warlingham station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Warlingham Village Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
With a portfolio of properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or send us an email.
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
What affects the price in Warlingham
All our prices include VAT. The things that change the price are:
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
- The type of building, from a house to a block or an office
- The height of the building and how the roof can be seen safely
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
The more you tell us, the easier it is to price the survey. When you contact us, tell us:

- What kind of property and roof it is

Do you need electronic leak detection in Warlingham?
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
We’re often asked to look at:
- Leaks under green or ballasted roofs
- A flat roof leak that cannot be traced
- Waterproofing to test before it’s covered
- Gaps at membrane joints
The streets around a church such as Church of All Saints 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 often show the first signs of wear.
Questions to ask before booking
- Their track record with similar roofs

Only when it is safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
