When to book a survey in Sutton Common
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Signs worth acting on include:
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
- Failed seams and laps
- Leaks through a covered membrane
For landlords with property near St Helier station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

- What’s outside the scope of the survey
- How soon the report will arrive
Electronic leak detection in Sutton Common: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. We are often asked to look into leaks showing away from the breach and leaks under green or ballasted roofs, across green roofs, roof terraces and balconies and flat roof membranes.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Sutton Common, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to.

Common questions in Sutton Common
Do you cover Sutton Common?
Yes, Sutton Common is one of the places we work. Every survey there gets the same written report with photographs.
Does a conservation area affect roof work in Sutton Common?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Just say which days work for you.
What do I do with the report?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
What is electronic leak detection?
A sound membrane blocks the test current, but a hole lets it through. That lets us find breaches that are too small to see.
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, photograph what we find and make notes for the report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. In a London area like Sutton Common, 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.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Agree roof access with the managing agent if it is shared
- If you are buying, let the agent know when we’re coming
- Make a note of anything you’d like us to look at
Book a survey
A quick phone call is usually the easiest start: call 07833 053749 or email us and we will ask a few questions about the roof. The price is agreed before a date is set.
Advice
Electronic leak detection around Sutton Common
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in 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. With Nonsuch Mansion about 2.1 miles south-west, Sutton Common sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
If you look after a building like Abbey Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Sutton Common is in London, so parking needs planning: let us know about parking bays, permits or a driveway as you book.

What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. We test where the roof suits it.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
