How electronic leak detection works in Ockham
Our ELD testing covers flat roofs in Ockham and the rest of London and South East England. A visit typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you’ve noticed a flat roof leak that can’t be traced and leaking laps in the waterproofing, a survey will tell you what’s going on.
Older buildings in small places like Ockham may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to.

Ockham questions
Do you cover Ockham?
Yes, Ockham is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How do I find out if my home in Ockham is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
What do I do with the report?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
Will you walk on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Will you repair the leak?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
Do you need to get into the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
How it works
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. For a village or hamlet like Ockham, the journey is planned beforehand: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Leave side gates unlocked
- Have any questions written down, so nothing gets missed
- If you’re buying, check with the agent that we can get in
Booking a survey
We survey roofs on weekdays, Saturdays and Sundays. To find a date that works for you, call 07833 053749 or email us.
Advice
Electronic leak detection around Ockham
The wider area around Ockham has a long history of building, with Byfleet Manor about 2.3 miles north. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark such as All Saints' Church, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings like Ripley Court School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Common roof problems in Ockham
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
A survey makes sense if you’ve noticed:
- Repairs that haven’t stopped the leak
- Holes left by work on the roof
- Gaps at membrane joints
- Waterproofing to test before it is covered
For landlords with property near Horsley station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
What to check before booking
- How much experience they have with roofs like yours
- What’s outside the scope of the survey
- What exactly goes into their report
- Their drone registration, if they fly one
What we look for on each type of roof
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.

Tips that help
You do not need to be a roofer to help. What helps most:
- Get leaks traced quickly
- Ask contractors to protect the membrane
- Test new membranes before covering them
- Clear flat roof outlets regularly
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
What a survey costs
Prices vary from roof to roof, for these reasons:
- The type of building, from a house to a block or an office
- Roof area
- Height and safe access
- Any need for thermal images or a drone flight
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.
