Landlord and commercial surveys in Broad Green
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when booking and we will plan the survey around it.
We survey roofs for letting agents and landlords as well as householders. The report gives you a dated record of the flat roof membrane, with photos, which helps you plan work between tenancies.
About our electronic leak detection in Broad Green
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. We’ll tell you if the roof can’t be tested. We survey liquid-applied waterproofing, single-ply roofs and roof terraces and balconies, and common reasons people get in touch are holes left by work on the roof and stains far from any visible defect.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Broad Green, 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.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Useful tips for Broad Green property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Act on new leaks promptly
- Do not keep patching the same spot
- Note where leaks show inside and when
- Use boards when working on the roof
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Broad Green questions
Is my home in Broad Green listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you carry out roof surveys in Broad Green?
Yes, Broad Green is one of the places we work. The survey and report are the same in Broad Green as anywhere else.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How much time does ELD need?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Share any details you have and we’ll confirm suitability.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where applicable.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Honest limits
In fairness, there are limits to any roof survey:
- The extent of water in the insulation
- Leaks from plumbing or windows
- Some conductive membranes
If in doubt, ring 07833 053749 or email us and we will suggest the right survey before booking. What our survey covers.
What we look at
- Flat roof membranes
- Green roofs
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
- Liquid-applied waterproofing
Should I look at the roof myself first?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Electronic leak detection around Broad Green
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 3.2 miles north lies Kingswood House, a reminder of how long the area around Broad Green has been built on. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
If you live in an older home near Church of St Saviour, the joins between later flat roofs and the old walls are where problems typically start. Take a building like Elmwood Infant School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Shop and office owners around Centrale Croydon may find that a flat roof over a business is out of sight and out of mind until it leaks.

How the survey changes by roof type
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
How it works
Once we have finished looking, we write up our findings in a report with photos. On timing, most surveys take 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 Broad Green, 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. We then look at what can be seen safely 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.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- 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.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Clear the way to the loft hatch
- Tell us where we can park nearby
