Electronic Leak Detection in Henwood
Know where you stand with the flat roof membrane before you decide what to do next. Electronic leak detection in Henwood.
- Leaks showing away from the breach
- Failed seams and laps
- Patched roofs that still leak
Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Find the breach before more patching
- Do not leave water getting in
- Note where leaks show inside and when
- Stay off the flat roof unless needed
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Don’t leave a flat roof leak running. Water under a membrane can spread.
About our electronic leak detection in Henwood
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you are worried about gaps at membrane joints and leaks under green or ballasted roofs, a survey will tell you what’s going on.
Some older homes in villages like Henwood are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Surveys for landlords and agents in Henwood
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant in advance.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
When to book a survey in Henwood
Holes in a membrane often come from feet, tools or debris. Some are too small to see, but still let water through.
Things that often lead to a survey include:
- Breaches around outlets and penetrations
- Water coming in under a flat roof
- Gaps at membrane joints
- New roofs to check before paving or planting
If you look after a shop, office or commercial unit, for example near Westgate Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Before booking anyone
- Is VAT included in the price?
- Whether the inside of the roof is included
- What the report includes, and whether it has photos
- Are they insured for the work?
What we do, step by step
We do not take risks to get a closer look. We inspect what can be seen safely, and if part of the roof cannot be seen, the report says so. The survey normally takes a length of time set by the membrane area and the build-up, which we set out in the quote. Rural addresses near Henwood can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Jot down any questions you want answered
- Note where any stains or damp appear
- Dig out any old roof reports or invoices
Book a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, phone 07833 053749 or drop us an email.

FAQs for Henwood
Is my home in Henwood listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Do you cover Henwood?
Yes, Henwood is within the area we cover. Our area covers London and South East England. You can phone 07833 053749 or use the contact form with the address and some details, and we will talk through which survey suits.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or send us an email for a quote.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Let us know about it when you book and we will plan the survey around it.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access as you book.
What electronic leak detection looks like in Henwood
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Henwood has a long history of building, with Appleton Manor about 1.7 miles west. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you own one of the older houses in the streets near Church of St Peter, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Anyone responsible for a site like Wootton St Peter's Church of England Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
