Electronic leak detection in Sepham Heath
You get a report showing the location of each breach, with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report; that’s for your roofer to price. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. If you are worried about punctures from foot traffic or tools and new membranes needing a check before handover, we can find out what’s behind it, on liquid-applied waterproofing, green roofs and roof terraces and balconies alike.
Flat roofs on exposed homes in small places like Sepham Heath take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

What happens if roof problems are left?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Outbuildings and barns around Sepham Heath are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your roof before booking.

What we look for on each type of roof
Bituminous membranes
Bituminous roofs frequently have laps and old repairs where breaches occur. Testing depends on the roof.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Practical tips
A little preparation and a few simple habits help. Our tips:
- Tell us about the membrane and build-up if you know it
- Note where leaks show inside and when
- Ask contractors to protect the membrane
- Do not let outlets block
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.

Flat roofs in Sepham Heath
About 3.1 miles north-east lies Lullingstone Castle, a reminder of how long the area around Sepham Heath has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Older houses across Kent frequently 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.
Take a building like Halstead Community Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Knockholt station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to Otford Lane Mission Church: flat-roofed rear additions and dormers added over the years are worth checking.

Questions from Sepham Heath
How do I find out if my home in Sepham Heath is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover Sepham Heath?
Yes, Sepham Heath is within the area we cover. We survey roofs across London and South East England. You can ring 07833 053749 or email us with the address and some details.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Mention it when you contact us and we will plan the survey around it.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
How is ELD priced?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks, and call 07833 053749 or drop us an email for a quote.
How long will testing take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
What happens on the day
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Sepham Heath, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
