How electronic leak detection works in Kensal Rise
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we’ll say so. It won’t show water getting in through brickwork or around frames. Our report keeps that distinction clear. You will also know what to check next. If you are worried about leaks through a covered membrane and gaps at membrane joints, a survey will tell you what’s going on, on green roofs, flat roof membranes and single-ply roofs alike.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Kensal Rise, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report works through the roof section by section, from the coverings down to the gutters. You’ll see the good as well as the bad.

Questions from Kensal Rise
Can parking be tricky for a visit in Kensal Rise?
Parking in Kensal Rise, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when booking.
Do you cover commercial flat roofs around Kensal Rise?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and they go into the written report.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
How do I book a survey in Kensal Rise?
Simply phone 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Will you check the loft?
If there’s a loft and safe access to it, yes. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
Should I look at the roof myself first?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Why get it checked now?
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. 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.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

What affects the cost of electronic leak detection
We confirm the price for your roof before you book. This is what makes a difference:
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- The size of the roof
- How many separate roofs there are, like extensions, dormers and garages
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before booking.

Here’s what helps us most when you get in touch:
- Why you want a survey: buying, a leak, a storm or new work
- Your postcode, so we can check access and travel
- The kind of building and roof involved
- When you need the report by

Electronic leak detection in Kensal Rise: local notes
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. Within a mile and a half or so of Kensal Rise there are several hotels, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
Winfield House, about 2.2 miles east, is one of the historic houses in the wider area around Kensal Rise. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan. If you look after a shop, office or commercial unit, for instance near Westfield London, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Kensal Rise is about 1 mile south-west of Kilburn, in Greater London. Kensal Rise gets the same service as everywhere else we work: a careful inspection, photos and a written report. Kensal Rise is one of the places in Greater London where we work. We also survey roofs in London.
Surveys in W10, NW10 and NW6 are booked the same way as anywhere else. You will find streets such as Hazel Road, Hiley Road and Kempe Road. If you are just outside Kensal Rise, we cover Kensal Green (1 mile west), Kilburn (1 mile north-east), Queen's Park (1 mile east), North Kensington (1 mile south) and Kensal Town (1 mile south-east). We also work in nearby towns such as London (6 miles south-east), City of Westminster (3 miles south-east), Marylebone (3 miles east), St Pancras (4 miles east), Shoreditch (6 miles east) and Walthamstow (9 miles north-east).
What’s near Kensal Rise

Open spaces near Kensal Rise include The Long Water and Campden Hill.
Do you need electronic leak detection in Kensal Rise?
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
A survey makes sense if you’ve noticed:
- New roofs to check before paving or planting
- Leaks showing away from the breach
- Repairs that haven’t stopped the leak
- Punctures from foot traffic or tools
For hotels and guest houses around Kensal Rise, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.
Choosing a roof surveyor
- Is there a chance to talk the report through?
- What the report includes, and whether it has photos
- Which viewpoints they use to see the roof
- Their drone registration, if they fly one
How it works
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In a London area like Kensal Rise, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- 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.
- You get a report with photos of each breach.
Before the survey
- Leave side gates unlocked
- Let us know about parking before the day
- Agree roof access with the managing agent if it’s shared
