Electronic leak detection in Colnbrook: what you get
We carry out electronic leak detection on flat roofs in Colnbrook and across London and South East England. Testing usually takes as long as needed for the membrane area and the build-up, which we set out in the quote. We quote electronic leak detection for each roof, as the method and time depend on the roof. The results come in a written report with photos. If you’re worried about new roofs to check before paving or planting and leaks under green or ballasted roofs, a survey will tell you what’s going on, on single-ply roofs, flat roof membranes and commercial flat roofs alike.
Some older homes in villages like Colnbrook are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. 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 is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, with the urgent items made clear.

Surveys for landlords and agents in Colnbrook
Letting agents can arrange access with tenants, at a time agreed in advance. Surveys run on weekdays and at weekends, which can make access easier.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait.
Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Ask contractors to protect the membrane
- Get leaks traced quickly
- Keep foot traffic on flat roofs to a minimum
- Don’t let outlets block
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
How the survey changes by roof type
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Do you need electronic leak detection in Colnbrook?
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
People usually book a survey when they’ve noticed something like this:
- Leaks showing away from the breach
- Leaking laps in the waterproofing
- Holes around roof penetrations
- Leaks that return after repairs
The streets around a church like Church of St Thomas are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Before you book any roof surveyor
- How much experience they have with roofs like yours
- Which parts of the roof they’ll actually see
- Whether the inside of the roof is included
- Whether they hold professional indemnity and public liability insurance
FAQs for Colnbrook
Do you cover smaller places like Colnbrook?
Yes, Colnbrook is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you cover Colnbrook?
Yes. We work right across London and the South East, and Colnbrook is part of that. You can phone 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Can you survey in bad weather?
Light rain does not normally stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather isn’t suitable.
Can you give me structural calculations?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, call 07833 053749 or send us an email.
Can you find leaks on a covered flat roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.

Flat and commercial roofs around Colnbrook
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around Colnbrook has a long history of building, with Frogmore House about 3 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.

What happens on the day
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Colnbrook, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- If it is not your property yet, arrange access through the agent
- Find any records of previous roof work
- Agree roof access with the managing agent if it is shared

Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
