Brent Park questions
Is parking a problem for a survey in Brent Park?
It can be, so it’s useful to let us know about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
How do I find out if my home in Brent Park is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so the building owner or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
How do I book a survey in Brent Park?
To arrange a survey, call 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Are you structural engineers?
No. Visible signs like deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
How do you choose the testing method?
The roof decides the method. We’ll explain why when we quote.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, tell us as you book.
Electronic leak detection in Brent Park
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. Common reasons to book are leaking laps in the waterproofing and leaks at pipes, outlets or fixings, on liquid-applied waterproofing, commercial flat roofs and flat roof membranes.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Brent Park, the roof above may belong to the building rather than one flat.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Flat roofs in Brent Park
There are several hotels within about a mile and a half of Brent Park, 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. With Pitzhanger Manor about 3.5 miles south-west, Brent Park sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Stonebridge Park station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a shop, office or commercial unit, for example near London Designer Outlet, flat roofs over shops and units are easy to forget until water comes through a ceiling.

- Parts of the roof covered by fixed equipment

- Flat roof membranes
- Commercial flat roofs
What affects the price in Brent Park
Several things affect the price of a survey:
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- The size of the roof
- The shape of the roof and its details
To find out what your survey will cost, call 07833 053749 or send us an email with the address and a few details. The price is agreed before a date is set.
Booking your survey
You don’t need to know any roofing terms. Just let us know:
- What made you get in touch
- The address and postcode of the property
- Any marks or damp showing indoors
- Whether there’s a loft hatch, a shared roof or tricky access
We confirm the exact price before booking, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or email us.
DIY checks: what’s safe
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
How the survey changes by roof type
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
How the survey works
On the day, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey usually takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. In Brent Park, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is often 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 agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Keep pets out of the way during the survey
- Check the loft hatch can be reached
- Mention any parking restrictions on your street
Book a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or drop us an email.

Common roof problems in Brent Park
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey makes sense if you’ve noticed:
- A flat roof leak that can’t be traced
- Breaches hidden under paving or planting
- Waterproofing to test before it’s covered
- Damp inside with no sign on the roof
For site and facilities teams at buildings such as Mitchell Brook Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Before booking any roof surveyor
- Whether you can ask questions once you have the report
- What experience they bring
- Whether the price includes VAT
- How they’ll see the roof: from ground level, the loft, the roof or by drone
