Flat roofs in South Harefield
Some villages in Buckinghamshire still have thatched roofs. 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. The wider area around South Harefield has a long history of building, with Ickenham Hall about 2.7 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you look after a building such as Harefield Infant School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. Take an older house close to Church of St Mary the Virgin: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

Electronic leak detection in South Harefield: what you get
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. We’ll say if your roof does not suit either method at the outset. If you’ve noticed patched roofs that still leak and a flat roof leak that can’t be traced, we can find out what’s behind it.
In a village or hamlet like South Harefield, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

What we are asked to look at in South Harefield
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny, but still let water through.
Most people get in touch when they’ve noticed one of these:
- Water coming in under a flat roof
- Leaks showing away from the breach
- Leaks through a covered membrane
- Gaps at membrane joints
For landlords with property near Denham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
What to check before booking
- What happens after the report arrives
- What exactly goes into their report
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether VAT is in the quoted price
Different roofs, different checks
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Why get it checked now?
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. Older and listed buildings around South Harefield may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before you book.
What you get with us
- Photographs and a written report every time
- Weekday and weekend surveys
- Independent findings on the roof’s condition
- Insured for professional indemnity and public liability

What we do, step by step
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit usually takes as long as needed for the roof’s area and construction, which we set out in the quote. Somewhere as small as South Harefield, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- If it is not your property yet, arrange access through the agent
- Gather any invoices or paperwork from past roof work
- If the roof is shared, arrange access with whoever manages the building

FAQs for South Harefield
Does a conservation area affect roof work in South Harefield?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover South Harefield?
We do. The survey and report are the same in South Harefield as anywhere else.
How long does electronic leak detection take?
It typically takes a length of time set by the roof’s area and construction, which we’ll explain when we quote.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
How do I arrange electronic leak detection in South Harefield?
Simply phone 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
When you need someone else
A survey is a close look at the flat roof membrane, but it cannot do everything. The main limits are:
- How wet the insulation is
- Sections we cannot safely access
- Repairing the breaches (that’s for your roofer)
If you are not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer. What our survey covers.
Roofs we survey in South Harefield
- Green roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
- Single-ply roofs
Before and after the survey
There is plenty you can do without going near the roof. What helps most:
- Keep foot traffic on flat roofs to a minimum
- Record dates and spots where water appears
- Tell us about the membrane and build-up if you know it
- Do not leave water getting in
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
