Woolmer Hill Electronic Leak Detection
We carry out electronic leak detection in Woolmer Hill and the rest of Surrey. Surveys run on any day of the week.
- Leaks through a flat roof with no obvious cause
- Waterproofing to test before it’s covered
- Leaks at pipes, outlets or fixings
How electronic leak detection works in Woolmer Hill
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. We survey flat roof membranes, single-ply roofs and roof terraces and balconies, and the problems we’re asked to look at most are leaks under green or ballasted roofs and new roofs to check before paving or planting.
Some older homes in villages like Woolmer Hill are listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, with the urgent items made clear.

FAQs for Woolmer Hill
Do you carry out roof surveys in Woolmer Hill?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is Woolmer Hill within the area you cover?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first, with the building owner or managing agent. Mention it when you contact us and we’ll plan the survey around it.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep a note of leaks after rain
- Avoid repeated repairs without finding the cause
- Have roof specifications to hand
- Check new waterproofing before handover
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
What we do, step by step
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes more time on a big roof than a small one, with the construction of the roof playing a part too. Around Woolmer Hill, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start by finding out what the roof is made of and where it leaks.
- 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.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Have any questions written down, so nothing gets missed
- Buyers: confirm access with the estate agent or seller
- For flats, make sure roof access has been agreed
Booking a survey
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you’re ready.
Related advice
Signs you need electronic leak detection in Woolmer Hill
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
It’s worth booking a survey if you’ve seen:
- Damp inside with no sign on the roof
- Water coming in under a flat roof
- Damage from equipment installers
- Failed seams and laps
If you let a flat or house near Haslemere station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Will the report include photos?
- What follow-up you get after the report

How the survey changes by roof type
EPDM rubber roofs
EPDM rubber roofs frequently last 30–50 years, but punctures and seam failures still happen.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Should I look at the roof myself first?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Local flat roofs in Woolmer Hill
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
Anyone responsible for a site like Camelsdale Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If your house is among the older ones in the streets near St Paul, the flat roofs on later extensions tend to wear out long before the main roof.
