Common questions in Bromley Common
How do I find out if my home in Bromley Common is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you cover Bromley Common?
Yes, Bromley Common is within the area we cover. We survey roofs across London and South East England. Just phone 07833 053749 or email us and let us know about the property.
How does ELD work?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Does the weather affect the survey?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Do you look in the loft space?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Is my roof suitable for ELD?
That depends on the roof’s membrane and layers. Share any details you have and we’ll check whether ELD will work.
Electronic leak detection in Bromley Common: what you get
We carry out electronic leak detection on flat roofs in Bromley Common and across London and the South East. Testing normally takes a length of time set by 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. You get a written report with photographs. We survey single-ply roofs, roof terraces and balconies and flat roof membranes, and the problems we’re asked to look at most are damage from equipment installers and leaks showing away from the breach.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Bromley Common, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a visit in Bromley Common, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from the ground, windows, the loft and, where it’s safe, the roof itself.
- 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.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- If you’re buying, check with the agent that we can get in
- Have any paperwork from past roof work to hand
- Jot down any questions you want answered
Booking a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you’re ready.

Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Suitability for ELD depends on the system.
Single-ply membranes
Some single-ply membranes suit electronic testing well, depending on the type and build-up.
Flat roofs in Bromley Common
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Bromley Common is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses like Bromley Palace, about 1.5 miles north-west, show how far back building in the area around Bromley Common goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Shop and office owners around The Mall may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. Anyone responsible for a site like Trinity Church of England Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What you can safely check yourself
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Surveys for landlords and agents in Bromley Common
Businesses and commercial landlords can book us too. Larger roofs take longer.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Signs you need electronic leak detection in Bromley Common
Holes in a membrane often come from feet, tools or debris. Some are too small to see but water still finds them.
Things that frequently lead to a survey include:
- Breaches hidden under paving or planting
- Leaks at pipes, outlets or fixings
- Patched roofs that still leak
- Damp inside with no sign on the roof
Take an older house close to Holy Trinity Church: the flat roofs on later extensions tend to wear out long before the main roof.
