Questions from Avisford
Do roofs near the sea, like those around Avisford, take more of a battering?
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 Avisford within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
What’s the best way to book?
To book, phone 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Does ELD include fixing the breach?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How is ELD priced?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just phone 07833 053749 or email us for a quote.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us when booking.
Electronic leak detection in Avisford
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. You get a written report with photos of each breach found. If you are worried about punctures from foot traffic or tools and patched roofs that still leak, a survey will tell you what’s going on, on green roofs, single-ply roofs and flat roof membranes alike.
Older buildings in small places like Avisford may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Electronic leak detection in Avisford: local notes
The coast is about 4 miles or less from Avisford, where sea air brings more salt and stronger wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like Walberton and Binsted CofE Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If yours is one of the older homes in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking.
Avisford is about 4 miles north-west of Littlehampton, in West Sussex. Avisford gets the same service as everywhere else we work: a close look at what can be seen safely, photographs and a clear written report. Avisford is one of the places in West Sussex where we work. There is also a page for Portsmouth.

When to book a survey in Avisford
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
We are often asked to look at:
- Leaks at pipes, outlets or fixings
- Leaks that return after repairs
- New roofs to check before paving or planting
- Holes left by work on the roof
For landlords with property near Barnham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking anyone
- Whether the loft space is looked at, where there is one
- Is there a chance to talk the report through?
- Whether the price includes VAT
- What the report includes, and whether it has photographs
How the survey works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Rural addresses near Avisford can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Let us know about parking before the day
- Keep pets in another room
- If the roof is shared, arrange access with whoever manages the building

Letting agents often book on a landlord’s behalf. We agree a time with the tenant beforehand.
Different roofs, different checks
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
How we price electronic leak detection
Prices vary from roof to roof, and it comes down to:
- Extra roofs, like extensions, dormers or garages
- How big the roof is
- The type of building, from a house to a block or an office
- Features like valleys, chimneys, dormers and parapets
For a price for your roof in Avisford, phone 07833 053749 or send us an email and let us know about the roof. We’ll confirm the figure before booking.
What we need to know
A little information up front helps. It is useful to include:
- Your timetable, like an exchange date
- Where water is showing inside, if it is
- Whether there is a loft hatch, a shared roof or tricky access
- What kind of property and roof it is
A quick phone call is usually the easiest start: call 07833 053749 or send us an email. The price is agreed before a date is set.
DIY checks: what’s safe
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
