About our electronic leak detection in Purley on Thames
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof cannot be tested. If you’re worried about leaks through a flat roof with no obvious cause and holes left by work on the roof, we can find out what’s behind it, on single-ply roofs, green roofs and flat roof membranes alike.
Flat roofs in smaller places like Purley on Thames 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. Standing water that lingers for days after rain is another sign worth watching for.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
- Limit access to the roof
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
Flat roofs in Purley on Thames
Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Mapledurham House about 0.6 miles north-east, Purley on Thames sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Take a building like Purley CofE Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you let a flat or house near Tilehurst station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What happens on the day
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely. The survey usually takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. With a bit of garden around a house, as there frequently is around Purley on Thames, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is looked at where it can be reached safely.

Related advice
Signs you need electronic leak detection in Purley on Thames
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.
We’re frequently asked to look at:
- Waterproofing to test before it’s covered
- Holes around roof penetrations
- Leaks showing away from the breach
- Gaps at membrane joints
If you run a business near Broad Street Mall, a flat roof over a business is out of sight and out of mind until it leaks.
Before booking any roof surveyor
- Their insurance cover
- What exactly goes into their report
- Is VAT included in the price?
- How they’ll see the roof: from ground level, the loft, the roof or by drone
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
When you need someone else
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Areas we cannot reach or that can’t be tested
- Roofs whose membrane or build-up is not suitable
- Fixing the holes we find

Purley on Thames: your questions answered
How do I find out if my home in Purley on Thames is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover smaller places like Purley on Thames?
Yes, Purley on Thames is covered. Our area covers London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Is it a structural engineer’s report?
No. Visible signs such as 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.
Does the report include photos?
Yes, plenty. Each finding is shown in a picture where possible, so you can see what we mean.
Do you climb onto every roof?
Only if it is safe. We inspect what can safely be seen: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we can’t see is noted in the report.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
Will you check the loft?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch.
