Local flat roofs in Wembley
Within a mile and a half or so of Wembley there are several hotels, and hotels, like offices and blocks of flats, frequently have flat roofs. If you look after one, a leak through a flat roof can put a room out of use. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in 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. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For businesses in and around places such as London Designer Outlet, a flat roof over a business is out of sight and out of mind until it leaks. Anyone responsible for a site like Wembley Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Wembley
We carry out electronic leak detection on flat roofs in Wembley and across London and South East England. A visit usually takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a photo-illustrated written report. We are often asked to look into leaks through a flat roof with no obvious cause and failed seams and laps, across flat roof membranes, green roofs and commercial flat roofs.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Wembley, the flat roof is often a shared part of the building.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what is not.

Your questions about electronic leak detection in Wembley
Is parking a problem for a survey in Wembley?
Sometimes, yes. If Wembley has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in Wembley is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you as you book.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
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 are a CAA-registered drone operator.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We check the parts we’re given access to, and the report makes that clear.
Do you climb onto every roof?
Only when it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and anything out of sight is recorded in the report.
What we do, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take 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. In a London area like Wembley, 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. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it’s safe.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before the survey
- Dig out any old roof reports or invoices
- Tell us where we can park nearby
- Keep pets in another room
Book a survey
Booking is simple: just call 07833 053749 or drop us an email and give us some details about the property and we’ll recommend the right survey. The price is agreed up front.
Advice
Signs you need electronic leak detection in Wembley
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
We’re frequently asked to look at:
- Leaks through a covered membrane
- Breaches around outlets and penetrations
- Water coming in under a flat roof
- Failed seams and laps
If you let a flat or house near North Wembley station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book anyone

- What they will not be able to tell you
- Will the report include photos?

Leave it or get it looked at?
Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Practical tips
You don’t need to be a roofer to help. What helps most:
- Stay off the flat roof unless needed
- Share any drawings of the roof
- Keep outlets clear of debris
- Note where leaks show inside and when
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
Any of our surveys can be booked by landlords, agents and building managers in Wembley. For a price for a let property or a block, call 07833 053749 or email us.
What a survey costs
All our prices include VAT. The things that change the price are:
- If the survey needs thermal imaging or a drone
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- Whether it is a home or a commercial building
Every price we give includes 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.
What we need to know
These details help when you get in touch:
- Where any leaks, stains or damp patches show inside
- Why you want a survey: buying, a leak, a storm or new work
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
To arrange a survey, call 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
