Electronic leak detection for homes and businesses in Knockholt Pound
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. We’ll tell you if the roof can’t be tested. If you’ve noticed new roofs to check before paving or planting and holes around roof penetrations, a survey will tell you what’s going on, on roof terraces and balconies, green roofs and flat roof membranes alike.
In a village or hamlet like Knockholt Pound, flat roofs are usually on extensions, garages, outbuildings or barn conversions. 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. If there are outbuildings or garages with flat roofs, mention them when booking.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Knockholt Pound can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive
- Point out any leaks or damp patches
- If you’re buying, check with the agent that we can get in
- Let us know about parking before the day

Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
What electronic leak detection looks like in Knockholt Pound
Down House, about 3.2 miles west, is one of the historic houses in the wider area around Knockholt Pound. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church such as St Katharine's Church are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you let a flat or house near Knockholt station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Halstead Community Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What else we do in Knockholt Pound
What a survey costs
Prices always include VAT. The things that change the price are:
- Features like valleys, chimneys, dormers and parapets
- If the survey needs thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- How many separate roofs there are, like extensions, dormers and garages
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
When you call or email, these details help:
- What made you get in touch
- Any photos you have, taken from the ground or a window
- Whether there is a loft hatch, a shared roof or tricky access
- Any deadline, like an exchange date
Booking is simple: just phone 07833 053749 or email us and give us some details about the property and we will recommend the right survey. The price is agreed up front.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where applicable.
