Electronic leak detection in Banstead
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. If you are worried about new membranes needing a check before handover and failed seams and laps, a survey will tell you what’s going on.
Around Banstead, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when you book. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
After the visit, you get a report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

The survey, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a survey in Banstead, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. Let us know about any garages, outbuildings or extensions you want included.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Jot down any questions you want answered
- For flats, make sure roof access has been agreed
- Gather any invoices or paperwork from past roof work
Arrange 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 ring 07833 053749 or drop us an email when you’re ready.

Your questions about electronic leak detection in Banstead
Is Banstead within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry out roof surveys in Banstead?
Yes. We cover the whole of London and South East England, and Banstead is part of that. Just ring 07833 053749 or use the contact form and let us know about the property.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Tell us what you know about the roof and we will confirm suitability.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
How quickly is the report sent?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.

How the survey changes by roof type
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers but it depends on the layers.
Inverted and paved roofs
We’ll tell you if your inverted or paved roof is not suitable.
Tips that help
These tips come from what we see on roofs every week:
- Do not leave water getting in
- Do not keep patching the same spot
- Limit access to the roof
- Use boards when working on the roof
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Flat roofs in Banstead
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Nonsuch Mansion about 2.7 miles north-west, Banstead sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Shop and office owners around The Ashley Centre may find that a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building like St Anne's Catholic Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Banstead station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Can I check my roof myself?
Look up at the roof after a storm, from ground level: 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.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
