Electronic leak detection in Hassocks
You get a report showing the location of each breach, with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a written report with photos. If you’re worried about repairs that haven’t stopped the leak and damp inside with no sign on the roof, a survey will tell you what’s going on, on roof terraces and balconies, single-ply roofs and green roofs alike.
Around a smaller place like Hassocks, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
Where we can’t see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t.

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Consider ELD before paving or planting goes on
- Use boards when working on the roof
- Don’t leave water getting in
- Do not let outlets block
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
The survey, step by step
We do not take risks to get a closer look. We inspect everything that’s safely in view, and anything we can’t see is noted in the report. The survey usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Parking around Hassocks is typically easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside, while taller roofs may need other vantage points or the drone where it applies.
- 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 the survey
- Tell us about parking before the day
- Show us where any leaks or stains appear
- Jot down any questions you want answered
Arrange a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or use the contact form.

What we’re asked to look at in Hassocks
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see often:
- Repairs that haven’t stopped the leak
- Leaks at pipes, outlets or fixings
- Damage from equipment installers
- Breaches hidden under paving or planting
The streets around a church such as St Francis of Assisi are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking.
What to check before booking
- How much experience they have with roofs like yours
- Whether the inside of the roof is included
- Their report turnaround times
- Will the report include photos?

Local flat roofs in Hassocks
If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building like Hassocks Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Hassocks station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Common questions in Hassocks
Will you come out to Hassocks?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route as you book.
Does a conservation area affect roof work in Hassocks?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Does the report include photographs?
Yes, plenty. Pictures sit next to the findings they show, so you can see what we mean.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How do you choose the testing method?
The roof decides the method. You’ll know which method we plan to use before we start.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
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, depending on the build-up.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will say if the test won’t work.
When you need someone else
It’s a careful look at the flat roof membrane, not the whole story. The main limits are:
- Repairing the breaches (that’s for your roofer)
- Parts of the roof covered by fixed equipment
- Water entering through details rather than the membrane
