Flat roof surveys for homes and businesses in Northfields
We inspect a flat roof from wherever it can safely be seen: from the roof itself where that’s safe, from windows and nearby vantage points, and from inside where there is access. We don’t walk on fragile rooflights or fragile roof sheeting. Where any area cannot be viewed safely, we say so in the report, so the limits of the survey are clear. If you are worried about loose or cracked edge trims and cracked or split membrane, we can find out what’s behind it, on upstands and outlets, felt flat roofs and mastic asphalt alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Northfields, the roof above may belong to the building rather than one flat.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Landlords, agents and block managers in Northfields
We survey roofs for landlords and agents as well as homeowners. The report gives you a dated record of the flat roof, with photos, useful for planning maintenance.

It’s a careful look at the flat roof, not the whole story. Its limits include:

- A fixed date for when the roof will need replacing
- The condition of the deck or insulation hidden under the covering

Flat roofs in Northfields
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Northfields has a long history of building, with Boston Manor about 0.5 miles south. 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, and any change of roofing material on a listed home needs checking with the council first.
As a London address, Northfields 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. A roof leak in a hotel or guest house around Northfields means lost rooms as well as repairs, so it pays to find faults before guests do. For site and facilities teams at buildings like Mount Carmel Catholic Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Northfields questions
Do you cover commercial flat roofs around Northfields?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Can parking be tricky for a visit in Northfields?
Sometimes, yes. If Northfields has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
How many surveys have you done?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How long does the survey take?
Most surveys take about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
What we do, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. A typical survey takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In Northfields, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- 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’s safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Tell us where we can park nearby
- For a flat or shared roof, check access with the building owner or managing agent
- Point out any leaks or damp patches
Getting a price
Our price is from £150, including VAT. The exact figure depends on the roof and the package, and you can phone 07833 053749 or use the contact form to find out.

Useful tips for Northfields property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Note the date and type of any roof work
- Note any new marks on ceilings beneath the roof
- Ask whoever fits equipment on the roof to make good the covering
- Book a survey every few years
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
Why it is worth a survey now in Northfields
Before replacing a flat roof, it is useful to know if you really need to. At times the trouble is a handful of failed details, and at times the whole covering is worn. Our report gives you the evidence to discuss with a roofer. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both with VAT included. You’ll know the exact price before booking.
Why book us in Northfields

What we look for on each type of roof
EPDM rubber
EPDM is a synthetic rubber membrane, frequently laid in a single sheet on smaller roofs. The survey looks at laps, edge trims, corners and signs of puncture.
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. The report shows where it’s cracking and how far it seems to extend.
