Electronic leak detection for homes and businesses in Bessels Green
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We will discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. If you are worried about water coming in under a flat roof and damage from equipment installers, we can find out what’s behind it.
In a village or hamlet like Bessels Green, 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. We simply plan the journey and access 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.

Electronic leak detection in Bessels Green: local notes
Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 2.2 miles south-east lies Knole House, a reminder of how long the area around Bessels Green has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you live in an older home near Chapel of the Good Shepherd, flat-roofed rear additions and dormers added over the years are worth checking. Take a building like Riverhead Infants' School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Prices for electronic leak detection in Bessels Green
Not every roof costs the same to survey, for these reasons:
- The use of thermal imaging or a drone
- Whether it’s a home or a commercial building
- How complicated the roof is, with its valleys, chimneys and parapets
- Roof area
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
What we need to know
We’ll usually ask about:
- Photos of the roof, taken safely from ground level or a window
- The reason for the survey, such as buying, a leak or storm damage
- The property’s address and postcode
- The type of building and roof, such as pitched or flat
We survey roofs seven days a week. To arrange a day that suits you, phone 07833 053749 or email us.
Bessels Green: your questions answered
Do you cover Bessels Green?
We do. Every survey there gets the same written report with photos.
Is my home in Bessels Green listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report.
What do I do with the report?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
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. The report will say if you need an engineer.
How do I book a survey in Bessels Green?
Simply ring 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date.
Will you walk on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
What we are asked to look at in Bessels Green
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
Here are some of the things we see often:
- Gaps at membrane joints
- Waterproofing to test before it’s covered
- Water coming in under a flat roof
- Damage from equipment installers
If you let a flat or house near Sevenoaks station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before booking
- Are they insured for the work?
- Whether the loft is part of the inspection
- How soon the report will arrive
- Whether VAT is in the quoted price
What we look for on each type of roof
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. Testing depends on the roof.
What we do, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. Older roofs in small places like Bessels Green can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Tell us where we can park nearby
- Leave a clear route to the loft
- Find any records of previous roof work
Book a survey
A quick phone call is typically the easiest start: ring 07833 053749 or use the contact form. The price is agreed before a date is set.

What electronic leak detection does not cover
It’s useful to know what a survey will not do before you book:
- Build-ups without a suitable layer below
- The extent of water in the insulation
- Parts of the roof covered by fixed equipment
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you before you book. What our survey covers.
Roof types and parts we check
- Green roofs
- Flat roof membranes
- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
- Single-ply roofs
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
