Common roof problems in Green Street
Joints and laps in a membrane can fail over time. A gap that is hard to see can let water in for months before it shows.
People normally book a survey after spotting something like this:
- Leaks through a flat roof with no obvious cause
- Punctures from foot traffic or tools
- Leaks through a covered membrane
- Failed seams and laps
If you live in an older home near Church of St Mary the Virgin, the joins between later flat roofs and the old walls are where problems usually start.
Choosing a roof surveyor

Electronic leak detection in Green Street: what you get
ELD can be carried out in more than one way. Low-voltage testing is typically done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. We will say if your roof does not suit either method at the outset. We survey commercial flat roofs, flat roof membranes and green roofs, and people most often book us about leaks under green or ballasted roofs and new roofs to check before paving or planting.
In a small place like Green Street, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, 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.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Local flat roofs in Green Street
Older buildings in Essex frequently have clay tiles and weatherboarding, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Ingatestone Hall, about 1.9 miles south-east, show how far back building in the area around Green Street goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings like Ingatestone Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Ingatestone station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Roof by roof
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Leave it or get it looked at?
A visual inspection can miss tiny holes. Electronic testing can find breaches you cannot see by eye, on suitable membranes. Where a roof is exposed, as many are in small places like Green Street, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

FAQs for Green Street
Is Green Street within the area you cover?
Yes, we do. We work right across London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Is my home in Green 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 is 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.
Does ELD work under paving or planting?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so the freeholder or managing agent needs to agree access. We can only inspect what we’re given access to.
Prices for electronic leak detection in Green Street
To price your survey, we check:
- How big the roof is
- The use of thermal imaging or a drone
- Commercial roofs and larger buildings
- The height of the building and how the roof can safely be seen
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Helping us price your survey
You don’t need to know any roofing terms. Just let us know:
- Where the property is, with the postcode
- Whether there’s a loft hatch, a shared roof or tricky access
- When you need the report by
- Photos of the roof, taken safely from ground level or a window
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or drop us an email.

How the survey works
Once we’ve finished looking, we write up our findings in a report with photographs, emailed to you. On timing, it usually takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting.

- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
