Why it is worth a survey now in Derringstone
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Older cottages and farmhouses around Derringstone can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

About our electronic leak detection in Derringstone
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Let us know about your roof to find out more. If you’ve noticed new membranes needing a check before handover and damage from equipment installers, a survey will tell you what’s going on, on single-ply roofs, commercial flat roofs and liquid-applied waterproofing alike.
Older buildings in small places like Derringstone may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Where we cannot see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. Cottages and farmhouses around Derringstone often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Find any records of previous roof work
- Note where any stains or damp appear
- Buyers: confirm access with the estate agent or seller

Advice
What electronic leak detection looks like in Derringstone
About 4.2 miles north-east lies Goodnestone Park, a reminder of how long the area around Derringstone has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For landlords with property near Snowdown station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Anyone responsible for a site like Barham Church of England Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. The streets around a church such as Church of St John the Baptist are frequently among the oldest in a place, and if yours is one of the older homes nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Rented homes, blocks and businesses
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Before and after the survey
From years of surveys, a few habits stand out as worth the effort:
- Tell us about the membrane and build-up if you know it
- Keep a note of leaks after rain
- Don’t leave water getting in
- Do not keep patching the same spot
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.

Your questions about electronic leak detection in Derringstone
Do you cover Derringstone?
Yes, Derringstone is one of the places we work. Every survey there gets the same written report with photographs.
Is my home in Derringstone listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, call 07833 053749 or drop us an email.
What insurance do you have?
We hold professional indemnity and public liability insurance.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Will you walk on the roof?
Not unless it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
Honest limits
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Leaks from walls, copings or rooflights
- Carrying out the repair work
- Some conductive membranes
