Electronic leak detection in Hayes: what you get
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you’ve noticed leaking laps in the waterproofing and punctures from foot traffic or tools, we can find out what’s behind it.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Hayes, the flat roof is frequently a shared part of the building.
Nothing in the report is left vague: where something needs attention, it says so plainly.

The survey, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Hayes runs like any other.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Keep pets out of the way during the survey
- Tell us about parking before the day
- If the roof is shared, arrange access with whoever manages the building

DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Tell us about it when you book and we’ll plan the survey around it.
Letting agents and landlords in Hayes book surveys as well as homeowners. The report gives you a dated record of the flat roof membrane, with photographs, which helps you plan work between tenancies.
Flat roofs in Hayes
Historic houses such as Bromley Palace, about 2 miles north, show how far back building in the area around Hayes goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For a London address like Hayes, it is useful to know about controlled parking before the day. If you look after a shop, office or commercial unit, for example near The Mall, flat roofs over shops and units are easy to forget until water comes through a ceiling.

- Features like valleys, chimneys, dormers and parapets
- Commercial roofs and larger buildings
- The number of roofs, including extensions and garages

Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
