Flat roofs in West Preston
The coast is about 1 mile or less from West Preston, 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. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Historic houses such as Ecclesden Manor, about 1.6 miles north-east, show how far back building around West Preston goes. Older houses nearby often have flat roofs added much later, built to very different standards from the main roof. If you own one of the older houses in the streets near The Parish Church of St Mary, the joins between later flat roofs and the old walls are where problems typically start.
West Preston is about 4 miles west of Worthing, in West Sussex. Whether the building in West Preston is a house, a flat or a commercial unit, we can survey the roof on a weekday or at the weekend. Our West Sussex coverage includes West Preston and the places around it. For surveys nearby, see our Brighton page.

Electronic leak detection for homes and businesses in West Preston
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It is testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. If you’ve noticed gaps at membrane joints and leaks through a flat roof with no obvious cause, a survey will tell you what’s going on.
Around West Preston, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It is worth mentioning them when you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

West Preston questions
Does a conservation area affect roof work in West Preston?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Does being near the coast affect roofs in West Preston?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Can every flat roof be tested?
It depends on the membrane and the build-up. Let us know what you know about the roof and we will check whether ELD will work.
How long will testing take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We’ll explain why when we quote.
For landlords and managing agents
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or use the contact form.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the survey around it.

Useful tips for West Preston property owners
These tips come from what we see on roofs every week, before and after a survey:
- Don’t leave water getting in
- Keep a note of leaks after rain
- Limit access to the roof
- Share any drawings of the roof
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
Check contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
When you need someone else
Some things cannot be seen without opening up the roof, and that sets some limits:
- Water entering through details rather than the membrane
- Areas we cannot reach or that can’t be tested
- Fixing the holes we find
Not sure which survey suits your roof? You can ring 07833 053749 or email us and we’ll tell you. What a survey covers and does not.

- Commercial flat roofs
- Single-ply roofs
- Flat roof membranes
- Liquid-applied waterproofing
What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Being in a smaller place like West Preston doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Agree roof access with the managing agent if it’s shared
- Gather any invoices or paperwork from past roof work
- If you are buying, check with the agent that we can get in
Arrange a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email with the address and the days you’d prefer.

How the survey changes by roof type
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
ELD often works on single-ply membranes but it depends on the product and layers.
Do you need electronic leak detection in West Preston?
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Signs worth acting on include:
- Holes left by work on the roof
- Breaches hidden under paving or planting
- Gaps at membrane joints
- Stains far from any visible defect
Take a building like Georgian Gardens Community Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- What’s outside the scope of the survey
- Their drone registration, if they fly one
- What happens after the report arrives
- What insurance they carry
