Questions from Bow
How do I find out if my home in Bow is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can you look at the flat roof of a hotel or office near Bow?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. For a bigger roof, you will get a quote based on the building.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
How long does electronic leak detection take?
It typically takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you when you book.
Electronic leak detection in Bow: what you get
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a photo-illustrated written report. If you’ve noticed leaks at pipes, outlets or fixings and leaks through a flat roof with no obvious cause, we can find out what’s behind it, on liquid-applied waterproofing, commercial flat roofs and flat roof membranes alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Bow shapes how it is checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What happens on the day
Once we have finished looking, we write up our findings in a report with photos, sent to you by email. As for time on site, most surveys take a length of time set by the roof’s area and construction, which we set out in the quote. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- If the roof is shared, arrange access with whoever manages the building
- Keep pets out of the way during the survey
- Let us know about any leaks, stains or damp patches you know of

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

Useful tips for Bow property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Let us know about the membrane and build-up if you know it
- Do not let outlets block
- Consider ELD before paving or planting goes on
- Ask contractors to protect the membrane
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Act on leaks quickly. Water under a membrane can spread.
Rented homes, blocks and businesses
Where a roof is shared: we need access agreed with whoever owns or manages the building. Tell us about it when booking and we’ll plan the visit with that in mind.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
Local flat roofs in Bow
There are several hotels within about a mile and a half of Bow, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Historic houses like Sutton House, about 1.6 miles north-west, show how far back building in the area around Bow goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
For hotels and guest houses around Bow, a roof problem found early is far less disruptive than one found by a guest. If you let a flat or house near Hackney Wick station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you run a business near Westfield Stratford City, a flat roof over a business is out of sight and out of mind until it leaks.
