Why get it checked now?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Tradespeople may need to travel further to a smaller place like Otford, so it helps to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.

Electronic leak detection for homes and businesses in Otford
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. If you’ve noticed punctures from foot traffic or tools and gaps at membrane joints, a survey will tell you what’s going on, on flat roof membranes, roof terraces and balconies and liquid-applied waterproofing alike.
Around a smaller place like Otford, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it. Ponding, splits and lifting edges are the signs to look for from a window.
Where we cannot see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Electronic leak detection around Otford
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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3.2 miles south lies Knole House, a reminder of how long the area around Otford has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Otford Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you live in an older home near Church of St Bartholomew, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you let a flat or house near Otford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What happens on the day
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. Most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. For a survey in Otford, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- 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 we arrive
- Clear the way to the loft hatch
- Let us know where we can park nearby
- Check we can get to the back of the property
Getting a price
Every survey is priced before it’s booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.
Advice
Questions from Otford
Do you cover Otford?
Yes, Otford is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is Otford within the area you cover?
Yes, Otford is on our map. Villages and rural addresses get the same survey as a town house.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. For a quote, phone 07833 053749 or drop us an email.
Are you structural engineers?
No. We note visible signs like sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Honest limits
It is a careful look at the flat roof membrane, not the whole story. The main limits are:
- How wet the insulation is
- Water entering through details rather than the membrane
- Roofs whose membrane or build-up is not suitable

Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Note where leaks show inside and when
- Keep outlets clear of debris
- Get leaks traced quickly
- Find the breach before more patching
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.
Landlords, agents and block managers in Otford
We survey roofs for landlords and agents as well as homeowners. The report gives you a dated record of the flat roof membrane, with photographs.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, and they’re priced for the size.
Checking the roof from ground level
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
