About our electronic leak detection in Knowl Hill
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we’ll say so. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You’ll also know what to check next. Common reasons to book are stains far from any visible defect and repairs that haven’t stopped the leak, on commercial flat roofs, single-ply roofs and liquid-applied waterproofing.
In a village or hamlet like Knowl Hill, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: 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 when you book.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Roof by roof
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. ELD can help locate them on suitable roofs.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We’ll say if the test won’t work.
Flat roofs in Knowl Hill
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses like Harleyford Manor, about 3 miles north, show how far back building in the area around Knowl Hill goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Knowl Hill Church of England Primary Academy will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Wargrave station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark like Saint Peter, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

Knowl Hill: your questions answered
Will you come out to Knowl Hill?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Do you cover Knowl Hill?
Yes, Knowl Hill is one of the places we work. The survey and report are the same in Knowl Hill as anywhere else, and visits run on weekdays and weekends.
Will you photograph what you find?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
How quickly is the report sent?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
How much time does ELD need?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
What we cannot see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Repairing the breaches (that’s for your roofer)
- Sections we cannot safely access
- Water entering through details rather than the membrane

What we look at

- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
- Commercial flat roofs
- Green roofs
How the survey works
Once we’ve finished looking, we write up our findings in a report with photographs. On timing, most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Knowl Hill can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Getting ready for the survey
- Let us know about parking near the property
- Show us where any leaks or stains appear
- Make sure the loft hatch can be reached

We survey roofs on any day of the week. To arrange a day that suits you, call 07833 053749 or use the contact form.

Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. In a place like Knowl Hill, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.

Prices for electronic leak detection in Knowl Hill
Prices vary from roof to roof, and it comes down to:
- The shape of the roof and its details
- Whether thermal imaging or a drone is needed
- Extra roofs, like extensions, dormers or garages
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or send us an email when you’re ready.
DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
