For landlords and managing agents

About our electronic leak detection in Coates
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. 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. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. We are often asked to look into leaks showing away from the breach and holes left by work on the roof, on roof terraces and balconies, single-ply roofs and flat roof membranes.
Flat roofs on exposed homes in small places like Coates take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
After the visit, you get a written report with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Your questions about electronic leak detection in Coates
Will you come out to Coates?
Yes, Coates is covered. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Coates is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
How do I book a survey in Coates?
Just phone 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
How the survey works
The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Notes and photographs go into the written report. The visit typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Coates needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it’s safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Jot down any questions you want answered
- If you are buying, let the agent know when we are coming

Getting a price
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or use the contact form.

Electronic leak detection around Coates
Historic houses like Bignor Roman Villa, about 2.1 miles south, show how far back building in the area around Coates goes. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If your house is among the older ones in the streets near Church of St Agatha, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For site and facilities teams at buildings like Fittleworth CofE Village School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Test new membranes before covering them
- Let us know about the membrane and build-up if you know it
- Stay off the flat roof unless needed
- Keep outlets clear of debris
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
What we can’t see
It’s useful to know what a survey won’t do before booking:
- Moisture spread under the membrane
- Leaks from plumbing or windows
- Some conductive membranes

Do you need electronic leak detection in Coates?
Holes in a membrane often come from feet, tools or debris. Many are tiny but water still finds them.
It is worth booking a survey if you’ve seen:
- Breaches hidden under paving or planting
- Water coming in under a flat roof
- Waterproofing to test before it is covered
- Damp inside with no sign on the roof
If you own a rental within reach of Pulborough station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking any roof surveyor
- Is there a chance to talk the report through?
- When you will get the report

- Whether VAT is added on top
