About our electronic leak detection in Dragons Green
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We will tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. We survey green roofs, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are water coming in under a flat roof and leaks showing away from the breach.
Somewhere as small as Dragons Green, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Electronic leak detection in Dragons Green: local notes
In Sussex, older roofs are frequently handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. If your home is older, it is 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.
If you own a rental within reach of Billingshurst station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you live in an older home near The Church of St Mary the Virgin, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Anyone responsible for a site like Shipley CofE Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

FAQs for Dragons Green
How do I find out if my home in Dragons Green is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Dragons Green in the area you cover?
We do. Every survey there gets the same written report with photos.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
When does the report arrive?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Does the weather affect the survey?
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. We will rearrange with you if the weather isn’t right.
Which days do you carry out surveys?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or drop us an email.

Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
Prices for electronic leak detection in Dragons Green
Prices always include VAT. The things that change the price are:
- Roof area
- The shape of the roof and its details
- The use of thermal imaging or a drone
- How tall the building is and how easy the roof is to see
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Getting in touch
Getting the details right at the start saves time. It helps to include:
- Photos of the roof, taken safely from ground level or a window
- When you need the report by
- Where any leaks, stains or damp patches show inside
- The kind of building and roof involved
To arrange a survey, ring 07833 053749 or send us an email with the address and what you’d like to know about the roof. We’ll confirm the price before you book.
Before and after the survey
These tips come from what we see on roofs every week:
- Limit access to the roof
- Make sure trades protect the waterproofing
- Have roof specifications to hand
- Consider ELD before paving or planting goes on
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Landlord and commercial surveys in Dragons Green
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.

The survey, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. In a small place like Dragons Green, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Clear the way to the loft hatch
- Leave side gates unlocked
Booking 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 send us an email when you’re ready.
