Henhurst Electronic Leak Detection

Electronic leak detection in Henhurst: what you get
You get a report showing the location of each breach, with photographs. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a written report with photos. We survey commercial flat roofs, liquid-applied waterproofing and flat roof membranes, and people most often book us about damage from equipment installers and leaks through a covered membrane.
In a village or hamlet like Henhurst, flat roofs are normally 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 booking.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Useful tips for Henhurst property owners
A survey works best with a little help from you, before and after. Some tips:
- Test new membranes before covering them
- Record dates and spots where water appears
- Clear flat roof outlets regularly
- Don’t keep patching the same spot
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Questions from Henhurst
Do you cover smaller places like Henhurst?
Yes, Henhurst is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is my home in Henhurst listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
How fast do I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us when booking.
Does the weather affect the survey?
Light rain is typically fine; heavy rain and wind are different. In strong wind or a downpour, a drone cannot fly and access may not be safe, so we’d move the date with you.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Will you check the loft?
Usually, if there is one and it can be reached safely. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
Will I get photos?
Yes. The report includes photographs of what we found.

What happens on the day
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Henhurst, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Keep pets inside or away from the areas we’re looking at
- Agree roof access with the managing agent if it’s shared
Getting a price
Booking is simple: just call 07833 053749 or drop us an email and give us some details about the property and we’ll explain which survey suits. The price is agreed up front.

Electronic leak detection in Henhurst: local notes
Henhurst is within about 4 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. With Cobham College about 1 mile south-east, Henhurst sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Sole Street station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Singlewell Primary School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

DIY checks: what’s safe
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
What happens if roof problems are left?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Do you need electronic leak detection in Henhurst?
Water travels under flat roof membranes. The stain inside can be far from the hole, so tracing it by eye is difficult.
A survey can pick up problems such as:
- Breaches hidden under paving or planting
- Stains far from any visible defect
- Leaks at pipes, outlets or fixings
- Water coming in under a flat roof
If your home is one of the older ones in the streets near Church of St Margaret, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

How the survey changes by roof type
Bituminous membranes
Older felt roofs often have seams and patches that can leak. Testing depends on the roof.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible, depending on the build-up.
