Green Street: your questions answered
How do I find out if my home in Green Street 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.
Will you come out to Green Street?
We do. Villages and rural addresses get the same survey as a town house.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, phone 07833 053749 or email us.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Mention it when you contact us and we’ll explain what’s needed.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Can you survey in bad weather?
Light rain does not usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we’ll arrange another day with you.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
About our electronic leak detection in Green Street
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. We’ll say if your roof doesn’t suit either method at the outset. Common reasons to book are leaks under green or ballasted roofs and damage from equipment installers, on flat roof membranes, single-ply roofs and roof terraces and balconies.
Flat roofs on exposed homes in small places like Green Street take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
How the survey works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Green Street needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Preparing for the visit
- Dig out any old roof reports or invoices
- Buyers: confirm access with the estate agent or seller
- For a flat or shared roof, check access with whoever owns or manages the building

Electronic leak detection in Green Street: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Wyllyotts Manor about 3.7 miles north-east, Green Street sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
The streets around a church such as St Michael and All Angels Church are often among the oldest in a place, and if yours is one of the older homes nearby, 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 businesses in and around places like Spires Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For site and facilities teams at buildings such as Parkside Community Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

When you need someone else
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Leaks from walls, copings or rooflights
- Roofs whose membrane or build-up isn’t suitable
- Repairing the breaches (that’s for your roofer)
If in doubt, call 07833 053749 or email us and we’ll point you to the right survey before booking. What our survey covers.
What this survey covers
- Green roofs
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Why act early in Green Street
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. For older village homes like those around Green Street, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Different roofs, different checks

Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
