Flat roof survey in Arnos Grove
Each flat roof is looked at from the safest viewpoints we have: from the roof itself where that’s safe, from windows and nearby vantage points, and from inside where there’s access. We don’t walk on fragile rooflights or fragile roof sheeting. If part of the roof can’t be seen or reached safely, the report says so, so you know exactly what was covered. If you’ve noticed cracked or split membrane and failed upstands where the roof meets a wall, we can find out what’s behind it, whatever the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Arnos Grove shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Why it’s worth a survey now in Arnos Grove
Most flat roofs are out of sight, so they’re easy to forget. Many owners only find out a roof is worn out when water comes through. A survey every few years stops that from catching you out. In Arnos Grove, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.

Do you need a flat roof survey in Arnos Grove?
The surface of a flat roof heats up and cools down far more than the rooms below. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
Here are some of the things we see often:
- Cracked or split membrane
- Gaps at upstands and abutments
- Damaged trims at the roof edge
- Pools of water lying on the roof
If you run a business near The Mall Wood Green, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
What to check before booking
- What the survey won’t cover
- What follow-up you get after the report
- Whether the price includes VAT
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID

Local flat roofs in Arnos Grove
Bruce Castle, about 2.6 miles south-east, is one of the historic houses in the wider area around Arnos Grove. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. If your home in Arnos Grove is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
As a London address, Arnos Grove can be tricky for parking: let us know about parking bays, permits or a driveway as you book. If you let a flat or house near New Southgate station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Your questions about flat roof surveys in Arnos Grove
Do you carry out roof surveys in Arnos Grove?
Yes, Arnos Grove is within the area we cover. We work right across London and the South East. You can ring 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
Can parking be tricky for a visit in Arnos Grove?
It depends on the street. If Arnos Grove has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Which flat roof coverings do you cover?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with the freeholder or managing agent. Let us know about it when booking and we’ll plan the survey around it.
How long does the survey take?
Most surveys take roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. We’ll confirm the timing when you book.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Will this cover the whole house?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and it isn’t a structural engineer’s report.
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check from a window for ponding after heavy rain
- Treat rooflights and old sheeting as fragile
- File the paperwork for the roof and any repairs
- Keep outlets clear of leaves and moss
Questions about the findings are always welcome. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, so you can talk the findings through.
Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.
Different roofs, different checks
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We check the seals and the covering around each one.
Felt and built-up roofs
The edges and upstands of a felt roof are usually where trouble starts. Every upstand and edge is looked at, with photos of any that have lifted or cracked.
How the survey works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. London terraces rarely offer a view of the whole roof from one spot, so in Arnos Grove we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Before the survey
- Find any records of previous roof work
- Check the loft hatch can be reached
- Have any questions written down, so nothing gets missed
Book a survey
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we will ask about the building and what you need. You will have a price before anything is arranged.
