Flat roof survey in Potters Bar: what you get
Offices, shops, industrial units and blocks of flats often sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. The photographed record helps you plan and budget for work. Commercial roofs are quoted for their size and access, so please call 07833 053749 or drop us an email with the address and an idea of the roof’s size. If you’re worried about standing water left after rain and loose or cracked edge trims, we can find out what’s behind it.
In a town like Potters Bar, flat roofs are common on rear extensions, garages, porches and dormers. Older ones are often felt, which frequently lasts around 15–20 years, while newer ones may be EPDM rubber or GRP fibreglass. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is often the first sign a flat roof needs attention.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Flat roof surveys around Potters Bar
The wider area around Potters Bar has a long history of building, with Wyllyotts Manor about 0.4 miles west. 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. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark like St. Mary's Church, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Potters Bar station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a shop, office or commercial unit, for example near Spires Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Potters Bar: your questions answered
How should I get ready for a visit in Potters Bar?
Not much. Keep pets out of the way, leave side gates unlocked and have any old roof paperwork handy, and the visit in Potters Bar can get straight on.
How do I find out if my home in Potters Bar is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover flat roofs on blocks of flats?
Yes. Commercial and residential flat roofs are both covered. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
How do I arrange a flat roof survey in Potters Bar?
Just ring 07833 053749 or send us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
How much does a flat roof survey cost in Potters Bar?
Flat roof survey starts from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so the freeholder or managing agent needs to agree access. We can only inspect what we’re given access to.
What’s in the report?
You get our findings in writing, part by part, with photos. The most urgent items are made clear.

What else we do in Potters Bar
When you need someone else
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Whether old sheeting or boards contain asbestos
- A promise that the roof will not leak in future
- Structural calculations, which need a structural engineer
If you are not sure which survey you need, phone 07833 053749 or use the contact form and we’ll give you a straight answer before you book. What our survey covers.
What we look at
- Single-ply membranes
- EPDM rubber
- Mastic asphalt
- Upstands and outlets
- GRP fibreglass
- Felt flat roofs
Roof by roof
EPDM rubber
An EPDM rubber roof is usually one large sheet, bonded to the deck. We check the laps, the edges, the corners and any punctures.
Rooflights and upstands
We do not walk on rooflights or fragile sheeting, and we treat older rooflights as fragile. We view them from safe positions and photograph what we see.
The survey, step by step
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take between one and two hours on an ordinary house, though large, tall or awkward roofs take more time. A visit in Potters Bar runs most smoothly with the loft hatch clear, side gates open and a parking spot in mind. Someone needs to let us in, so let us know who that will be.
- 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.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear
- Agree roof access with the managing agent if it’s shared

What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
For landlords and managing agents
With a portfolio of properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or drop us an email.
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run seven days a week, which helps when tenants work during the week.
