Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Tell us about the membrane and build-up if you know it
- Check trades protect the waterproofing
- Record dates and spots where water appears
- Get leaks traced quickly
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
How electronic leak detection works in Down Street
Our ELD testing covers flat roofs in Down Street and the rest of London and the South East. Testing normally takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Every roof is quoted on its size and build-up. The results come in a written report with photos. Typical surveys look at water coming in under a flat roof and gaps at membrane joints, on green roofs, commercial flat roofs and single-ply roofs.
Somewhere as small as Down Street, 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 when booking.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

FAQs for Down Street
Is my home in Down Street listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out roof surveys in Down Street?
Yes. We survey roofs across London and South East England, and Down Street is part of that. Just ring 07833 053749 or drop us an email and let us know about the property.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof, and ring 07833 053749 or use the contact form for a quote.
Can you find leaks on a covered flat roof?
Sometimes. The layers on top and the build-up below decide it, and some may need lifting. We’ll discuss it before we quote.
What happens next?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We will explain why when we quote.
Will you photograph what you find?
Yes. The report includes photos of what we found.
Common roof problems in Down Street
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Things that often lead to a survey include:
- Punctures from foot traffic or tools
- Failed seams and laps
- Leaks at pipes, outlets or fixings
- Leaks that return after repairs
For an older house near a landmark such as The Parish Church of St Andrew and St Mary, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- Whether the price includes VAT
- Their track record with similar roofs
- Will the report include photos?
- Will they check the loft as well as the outside?
What we do, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen, from the ground, from windows, in the roof space and by drone where it applies. Most surveys take a length of time set by the roof’s area and construction, which we’ll explain when we quote. Rural addresses near Down Street can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Have any paperwork from past roof work to hand
- For a flat or shared roof, check access with the building owner or managing agent
- Check the loft hatch can be reached
Book a survey
If you are buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.
Advice
Different roofs, different checks
Bituminous membranes
ELD is frequently possible on bituminous membranes, depending on what’s below.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Local flat roofs in Down Street
Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs, and oast houses and timber-framed Wealden hall houses are part of East Sussex’s older buildings. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there.
Take a building like Fletching Church of England Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you let a flat or house near Uckfield station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Can I check my roof myself?
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
