Flat roof survey in Bentley Heath, Greater London
We carry out flat roof surveys in Bentley Heath and the rest of Greater London. We survey on weekdays and at weekends.
- Leaks around rooflights
- Standing water left after rain
- Splits and cracks in the covering
How a flat roof survey works in Bentley Heath
Our Basic Survey, from £150, gives you a visual inspection with photographs and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. On a flat roof, moisture readings can help show whether water has got under the covering. Bigger commercial roofs are priced on their size and access. We survey single-ply membranes, mastic asphalt and upstands and outlets, and people most often book us about raised blisters across the surface and upstands pulling away from walls.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Bentley Heath, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Should I look at the roof myself first?
Look up at the roof after a storm, from ground level: 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.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we look at the roof.
What a survey costs
Our packages start from £150, inc. VAT. What you pay for your roof depends on:
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- The shape of the roof and its details
- Basic, Standard or Premium
Price depends partly on 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.
What to let us know when you contact us
Here’s what helps us most when you contact us:
- The reason for the survey, like buying, a leak or storm damage
- What kind of property and roof it is
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from the ground or a window
Unsure which package suits your roof? The easiest way is to phone 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.
Roof by roof
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. Any we find are noted and photographed.
GRP fibreglass
A well-laid GRP roof often lasts up to about 30 years. Hairline cracks over board joints are an early warning we look out for.

The survey, step by step
Every roof is different, but as a rough guide the survey takes between one and two hours on an ordinary house, and more on a big or complicated roof. You’re welcome to ask questions while we’re there. Surveys in Bentley Heath can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- 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.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
How to prepare
- Have any questions written down, so nothing gets missed
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
How to book
Photos help, if you have them. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or email us.

Flat roofs in Bentley Heath
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in 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 a good many flat ones, over rear extensions, dormers, garages and shops. About 0.9 miles north lies Wyllyotts Manor, a reminder of how long the area around Bentley Heath has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
For an older house near a landmark such as Church of King Charles and the Martyr, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Potters Bar station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Bentley Heath is about 1 mile south-west of Potters Bar, in Greater London. In Bentley Heath, as across Greater London, every roof gets the same careful survey. Our area takes in places right across Greater London, large and small. London is in our area too.

Bentley Heath: your questions answered
Can parking be tricky for a visit in Bentley Heath?
Typically it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Is Bentley Heath in the area you cover?
We do. The survey and report are the same in Bentley Heath as anywhere else.
How much is a survey?
Our price is from £150, including VAT. We confirm the exact price before you book, and it depends on the roof’s size, access and the package you choose. To get a price, phone 07833 053749 or drop us an email.
Do you look for flat roof leaks?
We check the whole roof, since water can travel before it shows inside. Splits, open laps, upstands, outlets and rooflights are all checked. Where nothing visible explains the leak, the report says what to try next.
How soon will I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Will you walk on the flat roof?
It depends on what’s safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
What types of flat roof do you survey?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. We record what the covering is and how it’s holding up.
Why get it checked now?
If you are buying, find out about the flat roof before you exchange. Once you’ve exchanged, any work on the roof is down to you. Our report gives you specific points to raise with the seller or agent. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
All our prices include VAT. Flat roof survey starts from £150, including VAT. You will know the price for your roof before booking.

What we are asked to look at in Bentley Heath
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
Problems we come across frequently include:
- Ponding water that does not drain away
- Failed upstands where the roof meets a wall
- Loose or cracked edge trims
- Blocked or damaged outlets
For businesses in and around places like Spires Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Choosing a roof surveyor
