Flat roof surveys in Kinsbourne Green: local notes
Historic houses such as Childwickbury Manor, about 4.1 miles south-east, show how far back building in the area around Kinsbourne Green goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you live in an older home near Saint Mary the Virgin, the joins between later flat roofs and the old walls are where problems normally start. If you own a rental within reach of Harpenden station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

How a flat roof survey works in Kinsbourne Green
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Bigger commercial roofs are priced on their size and access. We’re often asked to look into damaged trims at the roof edge and pools of water lying on the roof, on upstands and outlets, single-ply membranes and mastic asphalt.
Somewhere as small as Kinsbourne Green, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

When to book a survey in Kinsbourne Green
Many flat roof problems start at the details rather than the main surface. Upstands, edge trims, outlets and the kerbs around rooflights move and weather differently from the rest of the roof. Where they weren’t finished well, they tend to fail before anything else.
People normally book a survey after spotting something like this:
- Blisters and bubbles in the covering
- Loose or cracked edge trims
- Outlets choked with leaves and silt
- Failed upstands where the roof meets a wall
Shop and office owners around The Mall Luton may find that a flat roof over a business is out of sight and out of mind until it leaks.
Before you book anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Will they check the loft as well as the outside?
- How long they’ve been surveying roofs
- Is VAT included in the price?
What affects the cost of flat roof surveys
The price reflects the time and kit the roof needs. The main factors are:
- How many separate roofs there are, such as extensions, dormers and garages
- The type of building, from a house to a block or an office
- Height and safe access
- Features like valleys, chimneys, dormers and parapets
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
What to tell us when you contact us
Here’s what helps us most when you get in touch:
- When you need the report by
- Any marks or damp showing indoors
- How the loft is reached, if there is one
- The style of property, from a terrace to a block
Most bookings start with a short call: phone 07833 053749 or email us. You’ll have a price before anything is arranged.
What you can safely check yourself
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking.
What a flat roof survey doesn’t cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Fragile surfaces, which we do not walk on
- Hidden layers beneath the covering
- Asbestos testing, which needs a specialist asbestos surveyor
If in doubt, ring 07833 053749 or send us an email and we’ll suggest the right survey. The full list of what we check.
What we check
- GRP fibreglass
- EPDM rubber
- Single-ply membranes

Questions from Kinsbourne Green
Is Kinsbourne Green in the area you cover?
Yes. We work right across London and South East England, and Kinsbourne Green is part of that. Just call 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
Do you cover smaller places like Kinsbourne Green?
Yes, Kinsbourne Green is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when you book.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the building owner or managing agent. Mention it when you get in touch and we’ll plan the survey around it.
Can you tell me how long my flat roof will last?
We don’t give a fixed number of years, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
What’s the best way to book?
Just phone 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
How the survey changes by roof type
Felt and built-up roofs
Felt roofs frequently last around 15 to 20 years, depending on how they were laid and looked after. We record how yours is doing and where it’s weakest.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.

What else we do in Kinsbourne Green
What happens on the day
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes about 1–2 hours at most homes, though large, tall or awkward roofs take more time. You’re welcome to ask questions while we are there. In a hamlet or village like Kinsbourne Green, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Before we arrive
- Let us know about parking near the property
- Clear the way to the loft hatch
- Note where any stains or damp appear
Arrange a survey
Photos help, if you have them. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To get started, phone 07833 053749 or use the contact form.
