Electronic leak detection in Willesden: what you get
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. We survey flat roof membranes, roof terraces and balconies and commercial flat roofs, and common reasons people get in touch are damage from equipment installers and a flat roof leak that can’t be traced.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Willesden shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

Electronic leak detection around Willesden
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Fenton House, about 2.5 miles east, show how far back building in the area around Willesden goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
For businesses in and around places such as Brent Cross Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after. Parking in Willesden, as in most of London, takes a little planning: tell us about permits, visitor bays or off-street space when booking. Anyone responsible for a site like St Andrew and St Francis CofE Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Roof by roof
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We look at this first.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Why act early in Willesden
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. London’s older roofs often have bitumen felt underlay or none 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.
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 you book.

Prices for electronic leak detection in Willesden
Not every roof costs the same to survey, for these reasons:
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- The size of the roof
- The use of thermal imaging or a drone
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. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
We will normally ask about:
- Where water is showing inside, if it is
- Dates you’re working to, such as exchange
- Access details, like a loft hatch or a shared roof
- The kind of building and roof involved
Most bookings start with a short call: phone 07833 053749 or send us an email. The price is agreed before a date is set.
Willesden questions
Is parking a problem for a survey in Willesden?
Typically it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Is my home in Willesden listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you work in Willesden?
Yes. We survey roofs across London and South East England, and that includes Willesden.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Practical tips
These tips come from what we see on roofs every week:
- Note where leaks show inside and when
- Have roof specifications to hand
- Limit access to the roof
- Do not let outlets block
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
What happens on the day
We do not take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof can’t be seen, the report says so. The survey normally takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Tell us about parking before the day
- Keep pets inside or away from the areas we’re looking at
- Clear the way to the loft hatch
