Chandler's Cross questions
Is Chandler's Cross within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
How do I find out if my home in Chandler's Cross is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
Does the weather affect the survey?
Light rain is usually fine; heavy rain and wind are different. Strong wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability.
Does a flat roof survey replace a RICS survey?
No. Our survey covers the flat roof only. It isn’t a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. Many buyers use it alongside a building survey.
Do you use drones?
Yes, where it applies and safe. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
Flat roof survey in Chandler's Cross
Many commercial buildings and blocks of flats have big flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photographs so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so please call 07833 053749 or email us with the address and an idea of the roof’s size. We’re often asked to look into a sagging deck under the covering and cracked or split membrane, across EPDM rubber, felt flat roofs and GRP fibreglass.
Older buildings in small places like Chandler's Cross may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Why get it checked now?
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. A survey can find worn areas and failing details before that point, while there’s still time to plan the work. Where a roof is exposed, as many are in small places like Chandler's Cross, driving rain gets into any weakness, and damp in older walls is slow to dry out.
All our prices include VAT. Flat roof survey starts from £150, including VAT. You will know the price for the job before you book.

Common roof problems in Chandler's Cross
Flat roofs take the full force of the weather on a surface that drains slowly. Over the years, coverings harden, crack and start to come away at the edges. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
These are some of the problems a survey can pick up:
- Upstands pulling away from walls
- Pools of water lying on the roof
- Leaks around rooflights
- Splits, cracks and crazing
For site and facilities teams at buildings such as York House School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Before booking anyone
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What insurance they carry
- Whether the loft space is looked at, where there is one
- Whether VAT is added on top
What a flat roof survey looks like in Chandler's Cross
Chenies Manor House, about 3.2 miles west, is one of the historic houses in the wider area around Chandler's Cross. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Kings Langley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you run a business near Charter Place, a flat roof over a business is out of sight and out of mind until it leaks.

What affects the price in Chandler's Cross

- The size of the roof
- How complicated the roof is, with its valleys, chimneys and parapets
- The use of thermal imaging or a drone
- Whether you choose the Basic, Standard or Premium Survey
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Flat roof survey starts from £150, including VAT.
Booking your survey
To price your survey accurately, we will ask about:
- Where the property is, with the postcode
- Any deadline, such as an exchange date
- Where water is showing inside, if it is
- The type of building and roof, such as pitched or flat
Booking is simple: just call 07833 053749 or drop us an email and give us some details about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
What happens on the day
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit usually takes roughly 1–2 hours for a house, while a commercial roof takes nearer three to four hours. Rural addresses near Chandler's Cross can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
Getting ready for the survey
- For flats, check roof access has been agreed
- Find any records of previous roof work
- Move anything stored under the loft hatch
How to book
