Your questions about electronic leak detection in Denham
Do you carry out roof surveys in Denham?
Yes, Denham is one of the places we work. The survey and report are the same in Denham as anywhere else.
Is Denham within the area you cover?
Yes. Denham is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Tell us what you know about the roof and we will confirm suitability.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Which method do you use?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Electronic leak detection in Denham: what you get
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We’ll point you to the likely next step. We are frequently asked to look into patched roofs that still leak and breaches around outlets and penetrations, on single-ply roofs, roof terraces and balconies and green roofs.
In a village or hamlet like Denham, flat roofs are typically on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

What you can safely check yourself
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
What happens on the day
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. Older rural homes like those around Denham can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Check the loft hatch can be reached
- Mention any parking restrictions on your street
- Point out any leaks or damp patches

Electronic leak detection around Denham
Historic houses such as Ickenham Hall, about 2.5 miles east, show how far back building in the area around Denham goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Some villages in Buckinghamshire still have thatched roofs. 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.
If your home is one of the older ones in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building such as Denham Village School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you own a rental within reach of Denham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Practical tips
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Make sure trades protect the waterproofing
- Consider ELD before paving or planting goes on
- Note where leaks show inside and when
- Do not leave water getting in
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.
Landlord and commercial surveys in Denham

Landlords, agents and building managers in Denham and across Buckinghamshire can book any of our surveys. To discuss a property or a block, ring 07833 053749 or send us an email.
Why get it checked now?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Where a roof is exposed, as many are in small places like Denham, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
