About our electronic leak detection in Yiewsley
Our ELD report shows where each breach was found, with photographs. Your roofer can then repair those points rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. Results come in a written report with photos. If you are worried about failed seams and laps and leaks showing away from the breach, we can find out what’s behind it, whatever the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Yiewsley, the flat roof is often a shared part of the building.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to.

Electronic leak detection in Yiewsley: local notes
With Northolt Manor about 1.4 miles north-east, Yiewsley sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Yiewsley is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Shop and office owners around The Chimes may find that a flat roof over a business is out of sight and out of mind until it leaks. Controlled parking zones are common in London, so mention any permit rules for Yiewsley, along with any off-street space. Take an older house close to St Joseph the Worker & Dovetail Centre: the flat roofs on later extensions tend to wear out long before the main roof.

Surveys for landlords and agents in Yiewsley
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters.
What happens if roof problems are left?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. In Yiewsley, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

What a survey costs
A few things affect what a survey costs:
- How tall the building is and how easy the roof is to see
- Roof area
- Any need for thermal images or a drone flight
- The shape of the roof and its details
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Helping us price your survey
When you call or email, these details help:
- Pictures from the garden or a window, if you have them
- Whether there is a loft hatch, a shared roof or tricky access
- Dates you’re working to, such as exchange
- Your postcode, so we can check access and travel
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To send them or to book, phone 07833 053749 or drop us an email.
Your questions about electronic leak detection in Yiewsley
Is parking a problem for a survey in Yiewsley?
Sometimes, yes. If Yiewsley has controlled parking where you are, a visitor permit is the easiest answer.
Do you carry out roof surveys in Yiewsley?
We do. Every survey there gets the same written report with photographs.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we will confirm suitability.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability.
What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a London area like Yiewsley, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before the survey
- Mention any parking restrictions on your street
- Point out any leaks or damp patches
- If you are buying, check with the agent that we can get in
