Christmas Common Electronic Leak Detection
Wondering about the flat roof membrane at a property in Christmas Common? You can book electronic leak detection in Christmas Common and across Oxfordshire.
- Leaks showing away from the breach
- A flat roof leak that cannot be traced
- Holes left by work on the roof
What we look for on each type of roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Electronic leak detection in Christmas Common
There are different ELD methods. Low-voltage methods typically need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. If neither method suits your roof, we will tell you before any testing starts. If you’re worried about waterproofing to test before it’s covered and repairs that haven’t stopped the leak, a survey will tell you what’s going on, whatever the roof.
In a small place like Christmas Common, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend.

What happens on the day
After the inspection, everything we found is written up in a report with photos, sent to you by email. On timing, most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Christmas Common can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear
Getting a price
Booking is simple: just phone 07833 053749 or email us, let us know about the property and we’ll explain which survey suits. The price is agreed up front.

What affects the cost of electronic leak detection
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- House, block, shop or office
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- Whether thermal imaging or a drone is needed
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
Here’s what helps us most when you contact us:
- When you need the report by
- Photos of the roof, taken safely from ground level or a window
- What’s prompted the survey
- How the loft is reached, if there is one
A quick phone call is normally the easiest start: phone 07833 053749 or email us and we will ask a few questions about the roof. The price is agreed before a date is set.
Honest limits
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- Leaks from plumbing or windows
- Fixing the holes we find
- The extent of water in the insulation
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey before you book. What our survey covers.

Common roof problems in Christmas Common
Holes in a membrane often come from feet, tools or debris. Some are too small to see but water still finds them.
People typically book a survey after spotting one of these:
- Patched roofs that still leak
- A flat roof leak that can’t be traced
- Leaks under green or ballasted roofs
- Waterproofing to test before it’s covered
If you live in an older home near Church of the Nativity, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- Is VAT included in the price?
- Will they check the loft as well as the outside?
- Which viewpoints they use to see the roof
- Their drone registration, if they fly one
Christmas Common questions
Will you come out to Christmas Common?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you cover Christmas Common?
Yes. We work right across London and the South East, and Christmas Common is part of that. Just ring 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Can every flat roof be tested?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof will not work, we’ll say so before testing.
Which method do you use?
We choose the method that suits the roof. We’ll explain why when we quote.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the building owner or managing agent. We can only inspect what we are given access to.
How many surveys have you done?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
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. The report will say if you need an engineer.
Flat and commercial roofs around Christmas Common
Historic houses such as Stonor Park, about 2.9 miles south-east, show how far back building in the area around Christmas Common goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take a building like Icknield Community College: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
