How electronic leak detection works in Windmill Hill
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey green roofs, single-ply roofs and commercial flat roofs, and people most often book us about damp inside with no sign on the roof and failed seams and laps.
In smaller places like Windmill Hill, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. 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.
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, like when you want to compare after future work.

Windmill Hill questions
Is Windmill Hill within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
How do I find out if my home in Windmill Hill is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
What’s in the report?
You get our findings in writing, part by part, with photos. Points are put with the most urgent first where relevant.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Send us details of the roof, and phone 07833 053749 or use the contact form for a quote.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.
Which days do you carry out surveys?
Surveys run seven days a week. To arrange a date, call 07833 053749 or drop us an email.
Leave it or get it looked at?
Patching where you think the leak is frequently misses it. ELD shows the actual breach points. With lower homes, common in places like Windmill Hill, there is little between a roof defect and the ceiling, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.

Can I check my roof myself?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking and it will help the survey.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
When to book a survey in Windmill Hill
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Typical things we are asked to look at include:
- Holes around roof penetrations
- Leaks showing away from the breach
- Patched roofs that still leak
- Leaking laps in the waterproofing
Hotels and guest houses near Windmill Hill cannot easily close rooms for a leak.
Questions to ask before booking
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Will the report include photos?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Will they check the loft as well as the outside?
Prices for electronic leak detection in Windmill Hill
Several things affect the price of a survey:
- Features like valleys, chimneys, dormers and parapets
- House, block, shop or office
- Building height and the viewpoints available
- Extensions, dormers and garages with roofs of their own
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Booking your survey
What helps most when you contact us:
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
- Dates you’re working to, like exchange
- What made you get in touch
Getting a price is simple: just phone 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a smaller place like Windmill Hill, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Keep pets out of the way during the survey
- Leave side gates unlocked
- Tell us about parking before the day

Tips that help
From years of surveys, a few habits stand out:
- Do not let outlets block
- Use boards when working on the roof
- Have roof specifications to hand
- Consider ELD before paving or planting goes on
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
