Your questions about electronic leak detection in Marehill
Do you cover smaller places like Marehill?
Yes, Marehill is covered. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Do you cover Marehill?
Yes. We survey roofs across London and the South East, and Marehill is part of that. You can call 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Does the report include photographs?
Yes. Photos are part of every report.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
How much time does ELD need?
It normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
About our electronic leak detection in Marehill
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. If you’ve noticed breaches hidden under paving or planting and leaks that return after repairs, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Marehill may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Electronic leak detection in Marehill: local notes
About 1.4 miles west lies Old Place Manor, a reminder of how long the area around Marehill has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to Wiggonholt Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you own a rental within reach of Pulborough station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like St Mary's Church of England Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

What happens on the day
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Marehill 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.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey

Advice
What a survey costs
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- How many separate roofs there are, like extensions, dormers and garages
- The shape of the roof and its details
- The type of building, from a house to a block or an office
- How tall the building is and how easy the roof is to see
To find out what your survey will cost, phone 07833 053749 or drop us an email and tell us about the roof. The price is agreed before a date is set.
What we need to know
We will normally ask about:
- Dates you’re working to, such as exchange
- Any marks or damp showing indoors
- The kind of building and roof involved
- Why you want a survey: buying, a leak, a storm or new work
Most bookings start with a short call: ring 07833 053749 or drop us an email. You’ll have a price before anything is arranged.
Different roofs, different checks
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. Testing depends on the roof.
Green and ballasted roofs
ELD is easier on a new roof before it is covered.
What we cannot see
Without opening up the roof, some things stay hidden, and that sets some limits:
- Roofs whose membrane or build-up isn’t suitable
- How wet the insulation is
- Fixing the holes we find
If in doubt, phone 07833 053749 or drop us an email and we’ll suggest the right survey. What a survey covers and does not.
Roof types and parts we check
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
DIY checks: what’s safe
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
