Electronic Leak Detection in Andwell
Electronic leak detection to pinpoint holes in flat roof membranes in Andwell, carried out by an experienced roof surveyor. You get a clear written report with photographs.
- Leaks under green or ballasted roofs
- Stains far from any visible defect
- New roofs to check before paving or planting
What this survey cannot tell you
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Roofs whose membrane or build-up is not suitable
- Moisture spread under the membrane
- Leaks from walls, copings or rooflights
If you’re not sure which survey you need, call 07833 053749 or email us and we will give you a straight answer before booking. What our survey covers.

How electronic leak detection works in Andwell
There are different ELD methods. Low-voltage methods usually need a wet roof surface 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’ll explain our choice. If neither method suits your roof, we’ll tell you at the outset. We survey single-ply roofs, roof terraces and balconies and liquid-applied waterproofing, and the problems we’re asked to look at most are waterproofing to test before it’s covered and stains far from any visible defect.
Somewhere as small as Andwell, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

Surveys for landlords and agents in Andwell
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant in advance.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer.
How it works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Andwell can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Mention any parking restrictions on your street
- Check the loft hatch can be reached

Why it is worth a survey now in Andwell
Some breaches are too small to see. ELD picks up breaches a visual check might miss where the roof suits it. In a place like Andwell, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

FAQs for Andwell
Do you cover Andwell?
Yes. We survey roofs across London and South East England, and Andwell is part of that. You can ring 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
Is my home in Andwell listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Do you climb onto every roof?
Not unless it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
Do you use drones?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Checking the roof from ground level
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book, as it helps us focus the survey.
Practical tips
Nothing here needs a ladder. A few suggestions:
- Ask contractors to protect the membrane
- Act on new leaks promptly
- Keep a note of leaks after rain
- Have roof specifications to hand
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. It is easier to find holes before more layers are added.
What electronic leak detection looks like in Andwell
Thatch survives on some older buildings in Hampshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 4.2 miles north-west lies The Vyne, a reminder of how long the area around Andwell has been built on. 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.
Take an older house close to St Swithun's church: flat-roofed rear additions and dormers added over the years are worth checking. If you look after a shop, office or commercial unit, for example near Festival Place, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you let a flat or house near Hook station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
