Electronic leak detection in Higher Denham
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we’ll say so. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. We will point you to the likely next step. Common reasons to book are waterproofing to test before it’s covered and damp inside with no sign on the roof, across liquid-applied waterproofing, roof terraces and balconies and flat roof membranes.
In a small place like Higher Denham, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You’ll see the good as well as the bad.

Surveys for landlords and agents in Higher Denham
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or use the contact form.
When to book a survey in Higher Denham
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
It is worth booking a survey if you’ve seen:
- New roofs to check before paving or planting
- Leaking laps in the waterproofing
- Leaks through a covered membrane
- Leaks at pipes, outlets or fixings
For site and facilities teams at buildings such as Denham Green E-Act Primary Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
What to check before booking
- Whether the roof space is looked at, where there is one
- How long they’ve been surveying roofs
- Their report turnaround times
- Whether any drone flown is registered with the CAA
Honest limits
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Some conductive membranes
- Repairing the breaches (that’s for your roofer)
- Sections we cannot safely access
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we will tell you before you book. What our survey covers.
Roof types and parts we check
- Green roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
- Commercial flat roofs
- Single-ply roofs
Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Use boards when working on the roof
- Act on new leaks promptly
- Do not let outlets block
- Have roof specifications to hand
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Higher Denham: your questions answered
Do you carry out roof surveys in Higher Denham?
Yes, Higher Denham is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or email us and let us know about the property.
Is my home in Higher Denham listed or in a conservation area?
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.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
What’s the price of ELD?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or send us an email.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps.

Flat roofs in Higher Denham
Thatch survives on some older buildings in Buckinghamshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With Ickenham Hall about 3.6 miles east, Higher Denham sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church like St Mark's Hall are frequently among the oldest in a place, and if yours is one of the older homes nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you look after a shop, office or commercial unit, for instance near The Pavilions, a flat roof over a business is out of sight and out of mind until it leaks.

Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
How the survey works
Once we’ve finished looking, we write up our findings as a report with photographs. As for time on site, it usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Higher Denham, access is often 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.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Keep pets in another room
- Show us where any leaks or stains appear
- If you’re buying, let the agent know when we’re coming
