About our electronic leak detection in Hook
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. If you are worried about leaks showing away from the breach and leaks that return after repairs, a survey will tell you what’s going on, whatever the roof.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats 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 Hook shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Electronic leak detection around Hook
Fitznells Manor, about 2.6 miles south-east, is one of the historic houses in the wider area around Hook. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Take a building like St Paul's CofE Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of Chessington North station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

How it works
On the day, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can be seen safely, using the ground, windows, the loft and a drone where it applies. Most surveys take a time that depends on the roof’s area and construction, which we’ll explain when we quote. In Hook, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Mention any parking restrictions on your street
- Dig out any old roof reports or invoices
- Note where any stains or damp appear
Booking a survey
We confirm the price for your roof before booking, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.

How the survey changes by roof type
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes frequently appear.
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Surveys for landlords and agents in Hook
Landlords and letting agents in Hook book surveys as well as homeowners. The report gives you a dated record of the flat roof membrane, with photos, which helps you plan work between tenancies.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer.
Checking the roof from ground level
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.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
FAQs for Hook
Is parking a problem for a survey in Hook?
Parking in Hook, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Is Hook in the area you cover?
Yes. We work right across London and South East England, and Hook is part of that. You can ring 07833 053749 or email us with the address and a few details.
Does the weather affect the survey?
A survey can typically go ahead in light rain, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather isn’t suitable.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
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.
How soon will 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, such as an exchange date, let us know when booking.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
What a survey costs
Prices always include VAT. The things that change the price are:
- How big the roof is
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- The height of the building and how the roof can safely be seen
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
Getting in touch
The more you tell us, the easier it is to price the survey. When you get in touch, it’s useful to mention:
- The reason for the survey, such as buying, a leak or storm damage
- Dates you’re working to, such as exchange
- Photos of the roof, taken safely from the ground or a window
- The style of property, from a terrace to a block
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, call 07833 053749 or send us an email.
Common roof problems in Hook
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
Common reasons to book include:
- Holes left by work on the roof
- Patched roofs that still leak
- Failed seams and laps
- Stains far from any visible defect
If you own one of the older houses in the streets near St Paul's, flat-roofed rear additions and dormers added over the years are worth checking.
