Alfriston Electronic Leak Detection
Electronic leak detection in Alfriston and the rest of East Sussex. Surveys run on any day of the week.
- Breaches around outlets and penetrations
- Patched roofs that still leak
- Leaks under green or ballasted roofs
Tips that help
Most of what helps is simple and safe from ground level. Our suggestions:
- Limit access to the roof
- Avoid repeated repairs without finding the cause
- Don’t leave water getting in
- Test new membranes before covering them
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Electronic leak detection for homes and businesses in Alfriston
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. Common reasons to book are a flat roof leak that can’t be traced and stains far from any visible defect, across single-ply roofs, liquid-applied waterproofing and roof terraces and balconies.
Older buildings in small places like Alfriston may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later, such as when you want to compare after future work.

Checking the roof from the ground
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
What we do, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Alfriston can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- 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.
How to prepare
- Check the loft hatch can be reached
- For flats, make sure roof access has been agreed
- If it is not your property yet, arrange access through the agent

Flat and commercial roofs around Alfriston
The coast is about 4 miles or less from Alfriston, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For an older house near a landmark like Church of St. Andrew, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For site and facilities teams at buildings such as Alfriston School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Alfriston is about 3 miles north-east of Seaford, in East Sussex. Wherever you are in Alfriston, we can come and survey your property. Alfriston is one of the places in East Sussex we cover for electronic leak detection. For surveys nearby, see our Brighton page.
We cover every part of BN26 for electronic leak detection. We offer electronic leak detection to properties on High Street, Ropewalk and West Street and the roads around them. Close by, we survey roofs in Winton (1 mile north), Lullington (1 mile south-east), Dukes Green (1 mile south), Milton Street (1 mile north-east) and Alciston (2 miles north-west). Within a short drive, we also cover Eastbourne (6 miles east), Bexhill-on-Sea (14 miles east), Seaford (3 miles south-west), Lewes (8 miles north-west), Hailsham (6 miles north-east) and Uckfield (11 miles north).

What we’re asked to look at in Alfriston
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
A survey makes sense if you’ve noticed:
- Patched roofs that still leak
- Water coming in under a flat roof
- Gaps at membrane joints
- New roofs to check before paving or planting
If you let a flat or house near Berwick (Sussex) station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Choosing a roof surveyor
- What the survey won’t cover
- Their report turnaround times
- Whether the roof space is looked at, where there is one
- Whether any drone flown is registered with the CAA
What we look for on each type of roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but can still be punctured.
Your questions about electronic leak detection in Alfriston
Will you come out to Alfriston?
Yes, Alfriston is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is the coastal weather around Alfriston hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
How experienced are you?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys.
How much time does ELD need?
Testing usually takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting.
Will you photograph what you find?
Yes. The report includes photos of what we found, so you can see each point for yourself.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Let us know about it when you book and we will plan the survey around it.
