Electronic leak detection in North Mundham: what you get
There are different ELD methods. Low-voltage methods normally 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 explain which we’ll use. If neither method suits your roof, we will tell you at the outset. We survey roof terraces and balconies, green roofs and flat roof membranes, and the problems we’re asked to look at most are punctures from foot traffic or tools and leaks through a covered membrane.
Somewhere as small as North Mundham, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them as you book.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

When to book a survey in North Mundham
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
Problems we come across frequently include:
- New membranes needing a check before handover
- Holes left by work on the roof
- Stains far from any visible defect
- Leaks under green or ballasted roofs
If you own a rental within reach of Chichester station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before you book any roof surveyor
- Whether the price includes VAT
- How they plan to inspect the roof safely
- Whether you can ask questions once you have the report
- How much experience they have with roofs like yours
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
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.
Electronic leak detection around North Mundham
North Mundham lies within about 3 miles of the sea, 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. Historic houses like Goodwood House, about 4 miles north, show how far back building in the area around North Mundham goes. 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 yours is one of the older homes in the streets near The Parish Church of St Stephen, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Anyone responsible for a site like North Mundham Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

- Water entering through details rather than the membrane

- Commercial flat roofs
- Single-ply roofs
- Green roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
What we do, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. The whole visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere like North Mundham needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Mention any parking restrictions on your street
- Leave a clear route to the loft
- For a flat or shared roof, check access with whoever owns or manages the building

What else we do in North Mundham
What happens if roof problems are left?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. In a place like North Mundham, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.
For a price for your roof in North Mundham, call 07833 053749 or send us an email with the address and a few details. The price is agreed before a date is set.

North Mundham questions
Do you cover smaller places like North Mundham?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does a conservation area affect roof work in North Mundham?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you as you book.
How do I arrange electronic leak detection in North Mundham?

What we look for on each type of roof
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
