FAQs for Paddington Green
Does a conservation area affect roof work in Paddington Green?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is parking a problem for a survey in Paddington Green?
Normally it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
When does the report arrive?
Report times are set by the package. 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, let us know when you book.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where applicable, and the report records anything we couldn’t see.

Electronic leak detection for homes and businesses in Paddington Green
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 can repair them. You get a report with photos of each breach found. We survey roof terraces and balconies, liquid-applied waterproofing and single-ply roofs, and people most often book us about breaches around outlets and penetrations and leaks through a flat roof with no obvious cause.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Paddington Green, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
- Avoid repeated repairs without finding the cause
- Note where leaks show inside and when
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Don’t leave a flat roof leak running. Water under a membrane can spread.
For landlords and managing agents
Landlords and letting agents in Paddington Green book surveys as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane, which helps you plan work between tenancies.
Letting agents can arrange access with tenants. We survey on weekdays and at weekends, which helps when tenants work during the week.
Why get it checked now?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.

How we price electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- Chimneys, valleys, parapets and other details
- Whether thermal imaging or a drone is needed
- How big the roof is
- Extensions, dormers and garages with roofs of their own
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to let us know when you get in touch
There’s no need for technical words. Just let us know:
- The reason for the survey, such as buying, a leak or storm damage
- Your timetable, such as an exchange date
- Whether there is a loft hatch, a shared roof or tricky access
- Pictures of the roof from a safe spot, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or use the contact form with the address and the days you’d prefer.
What we can’t see
To be straight with you, there are limits to any roof survey:
- Repairing the breaches (that is for your roofer)
- The extent of water in the insulation
- Areas we can’t reach or that cannot be tested
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before you book. What a survey covers and does not.

What electronic leak detection looks like in Paddington Green
Paddington Green has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you let a flat or house near London Paddington station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Historic houses like Winfield House, about 0.9 miles north-east, show how far back building around Paddington Green goes. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once. Shop and office owners around Harrods may find that a flat roof over a business is out of sight and out of mind until it leaks.

How the survey works
After the inspection, everything we found is written up in a report with photos, sent to you by email. On timing, most surveys take a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In Paddington Green, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit 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 near the property
- Leave side gates unlocked
- Dig out any old roof reports or invoices
