High Barnet: your questions answered
Can parking be tricky for a visit in High Barnet?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Is High Barnet in the area you cover?
Yes. We survey roofs across London and the South East, and High Barnet is part of that. Just phone 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Is it a structural engineer’s report?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we’ll agree the details when you book.
Should I worry about standing water on my flat roof?
Standing water a day or two after rain normally needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
How much does a flat roof survey cost in High Barnet?
Flat roof survey starts from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, including VAT.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Flat roof survey in High Barnet: what you get
Each flat roof is looked at from the safest viewpoints we have: from the roof itself where that is safe, from windows and nearby vantage points, and from inside where there’s access. Fragile rooflights and fragile sheets are never walked on. If part of the roof can’t be seen or reached safely, the report says so, so you know exactly what was covered. We survey single-ply membranes, mastic asphalt and GRP fibreglass, and people most often book us about water getting in at rooflights and edge trims that have lifted or split.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In High Barnet, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Should I look at the roof myself first?
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
How the survey works
The visit has one job: to see as much of the flat roof as can safely be seen and record it clearly. Notes and photographs go into the written report. It typically takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. Many London properties are flats or terraces with no 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 when you book.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can safely be seen.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a written report with photos and our recommendations.
How to prepare
- Find any records of previous roof work
- Jot down any questions you want answered
- Check the loft hatch can be reached

Why it is worth a survey now in High Barnet
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. Once you’ve exchanged, any work on the roof is down to you. A report gives you facts to put to the seller or agent. 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.
All our prices include VAT. Flat roof survey starts from £150, including VAT. We confirm the price for your survey before booking.
Why book us in High Barnet

Flat and commercial roofs around High Barnet
Wyllyotts Manor, about 2.9 miles north, is one of the historic houses in the wider area around High Barnet. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For site and facilities teams at buildings such as Foulds School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. As a London address, High Barnet can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised. If you own one of the older houses in the streets near Christ Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

How we price flat roof surveys
Prices vary from roof to roof, and it comes down to:
- The size of the roof
- Whether it’s a home or a commercial building
- If the survey needs thermal imaging or a drone
- Basic, Standard or Premium
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. The roof’s size, height and access matter as well.

- Pictures of the roof from a safe spot, if you have them

- The style of property, from a terrace to a block
To arrange a survey, phone 07833 053749 or drop us an email and let us know the address and what’s prompted the survey. You will know the price before anything is booked.
What this survey cannot tell you
Before you book, it is worth knowing what a survey will not do:

- Testing older roof sheets for asbestos
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
