Why get it checked now?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached so attention can go to the right place. Older cottages and farmhouses around Twitton can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.

How electronic leak detection works in Twitton
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. We survey green roofs, single-ply roofs and flat roof membranes, and the problems we’re asked to look at most are damp inside with no sign on the roof and leaks under green or ballasted roofs.
Some older homes in villages like Twitton are listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Twitton questions
Do you cover smaller places like Twitton?
We do. Villages and rural addresses get the same survey as a town house.
How do I find out if my home in Twitton is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How experienced are you?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
Is this a RICS survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.

What else we do in Twitton
What affects the cost of electronic leak detection
Prices always include VAT. The things that change the price are:
- How many separate roofs there are, like extensions, dormers and garages
- Building height and the viewpoints available
- Commercial roofs and larger buildings
- The use of thermal imaging or a drone
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
To price your survey accurately, we will ask about:
- Where water is showing inside, if it is
- When you need the report by
- Photos of the roof, taken safely from the ground or a window
- The property’s address and postcode
We confirm the price for the job before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or email us.
What we do, step by step
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself 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 Twitton, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Preparing for the visit
- Check we can get to the back of the property
- Agree roof access with the managing agent if it is shared
- Have any questions written down, so nothing gets missed

Landlords, agents and block managers in Twitton
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait.
When to book a survey in Twitton
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
It is worth booking a survey if you’ve seen:
- Punctures from foot traffic or tools
- Patched roofs that still leak
- Gaps at membrane joints
- Leaks under green or ballasted roofs
The streets around a church such as Twitton Mission Church are often among the oldest in a place, and if your house is among the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
What to check before booking
- Is there a chance to talk the report through?
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether the loft space is looked at, where there is one
- Will the report include photos?

Lullingstone Castle, about 3.3 miles north, is one of the historic houses in the wider area around Twitton. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.

Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Ask contractors to protect the membrane
- Record dates and spots where water appears
- Check new waterproofing before handover
- Do not let outlets block
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Act on leaks quickly. Water under a membrane can spread.
