How the survey changes by roof type
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Electronic leak detection in Crowmarsh Gifford: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. If testing is not possible, we will say so. We survey commercial flat roofs, flat roof membranes and green roofs, and common reasons people get in touch are stains far from any visible defect and leaks that return after repairs.
In a small place like Crowmarsh Gifford, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, typically 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 is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put in order of urgency where relevant.

What happens if roof problems are left?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye, on suitable membranes. In a small place like Crowmarsh Gifford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every price we give includes 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.

Questions from Crowmarsh Gifford
Does a conservation area affect roof work in Crowmarsh Gifford?
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 Crowmarsh Gifford?
Yes. We cover the whole of London and South East England, and Crowmarsh Gifford is part of that. Just ring 07833 053749 or email us and let us know about the property.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
Can you survey in bad weather?
Some surveys depend on the weather more than others. 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 aren’t right, we’ll talk to you about another date.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Tell us what you know about the roof and we will check whether ELD will work.
What this survey can’t tell you
In fairness, there are limits to any roof survey:
- Roofs whose membrane or build-up is not suitable
- Sections we can’t safely access
- Moisture spread under the membrane
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we will tell you before booking. What a survey covers and does not.
What we check
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Single-ply roofs
- Green roofs
How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Crowmarsh Gifford frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.
- 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.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- Check pets are kept safely away
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at

Electronic leak detection in Crowmarsh Gifford: local notes
The wider area around Crowmarsh Gifford has a long history of building, with Brightwell Manor about 2.7 miles west. 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. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Cholsey station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to Church of St Mary Magdalene: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
