About our electronic leak detection in Ottershaw
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs aren’t part of the report; that is 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. We survey green roofs, single-ply roofs and roof terraces and balconies, and common reasons people get in touch are breaches around outlets and penetrations and new roofs to check before paving or planting.
Flat roofs in smaller places like Ottershaw can be more exposed, especially where nothing shelters them, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

What we look for on each type of roof
EPDM rubber roofs
Some EPDM membranes conduct electricity, which can rule out some methods. We will say if the test won’t work.
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
What else we do in Ottershaw
Can I check my roof myself?
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Your questions about electronic leak detection in Ottershaw
Will you come out to Ottershaw?
Yes, Ottershaw is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Ottershaw?
Yes, Ottershaw is within the area we cover. We survey roofs across London and South East England. You can call 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Is this a RICS survey?
No. We check the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put with the most urgent first where relevant.

Local flat roofs in Ottershaw
About 0.8 miles north lies Botleys Mansion, a reminder of how long the area around Ottershaw 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. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Ottershaw Christchurch Church of England Junior School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to Christ Church: the joins between later flat roofs and the old walls are where problems typically start.

Common reasons to book include:
- Punctures from foot traffic or tools
- Patched roofs that still leak
- Leaks through a flat roof with no obvious cause
- Leaks through a covered membrane
Landlords with a home close to Chertsey station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking anyone
- What happens after the report arrives
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What the survey won’t cover
- What exactly goes into their report
The survey, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take as long as needed for the membrane area and the build-up, which we’ll explain when we quote. In a smaller place like Ottershaw, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside, while taller roofs may need other vantage points or the drone where it applies.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Make sure the loft hatch can be reached
- Tell us about any leaks, stains or damp patches you know of
Arrange a survey
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or send us an email.
