Different roofs, different checks
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Electronic leak detection in Frieth
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. We’ll say if ELD won’t work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. If you are worried about new membranes needing a check before handover and damp inside with no sign on the roof, a survey will tell you what’s going on.
In a small place like Frieth, 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, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
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.

Useful tips for Frieth property owners
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Find the breach before more patching
- Limit access to the roof
- Have roof specifications to hand
- Clear flat roof outlets regularly
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Act on leaks quickly. Water under a membrane can spread.
How it works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. It typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Frieth, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Have any paperwork from past roof work to hand
- Mention any parking restrictions on your street
- Leave a clear route to the loft
Booking a survey
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or send us an email.

What you can safely check yourself
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.
Your questions about electronic leak detection in Frieth
How do I find out if my home in Frieth is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is Frieth within the area you cover?
Yes, Frieth is on our map. A small place gets exactly the same survey as a big one.
Will you go up on the roof?
Only if it’s safe. We look at everything that can be seen safely: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. Anything we can’t see is noted in the report.
Do you take photos of the roof?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Is the repair part of the test?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
Do you need electronic leak detection in Frieth?
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in long before anyone notices.
Common reasons to book include:
- Repairs that haven’t stopped the leak
- Stains far from any visible defect
- Leaks under green or ballasted roofs
- New roofs to check before paving or planting
Anyone responsible for a site like Frieth Church of England Combined School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Questions to ask before booking
- Is VAT included in the price?
- How much experience they have with roofs like yours
- Whether they hold professional indemnity and public liability insurance
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What we cannot see
A survey is a close look at the flat roof membrane, but it cannot do everything. The main limits are:
- Some conductive membranes
- Repairing the breaches (that’s for your roofer)
- Water entering through details rather than the membrane

Flat roofs in Frieth
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Frieth has a long history of building, with West Wycombe Park House about 3.2 miles north-east. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
The streets around a church such as Church of St John the Evangelist are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Marlow station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
