Flat roof survey in Stroud Green, Greater London
A careful look at the flat roof at your property in Stroud Green, and put it all in a photo-illustrated written report.
- Cracked or split membrane
- A sagging deck under the covering
- Blocked or damaged outlets
About our flat roof survey in Stroud Green
A flat roof leak often travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. Whoever carries out the work then has a clear starting point. We survey mastic asphalt, single-ply membranes and upstands and outlets, and common reasons people get in touch are damaged trims at the roof edge and blocked or damaged outlets.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Stroud Green, the flat roof is often a shared part of the building.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What a flat roof survey does not cover
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Whether old sheeting or boards contain asbestos
- A fixed date for when the roof will need replacing
- A structural engineer’s assessment of the deck

Local flat roofs in Stroud Green
Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Witanhurst about 1.9 miles west, Stroud Green sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Harringay station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For a London address like Stroud Green, it helps to know about controlled parking before the day.

Do you need a flat roof survey in Stroud Green?
Water that does not drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Problems we come across often include:
- Splits, cracks and crazing
- Raised blisters across the surface
- Dips that suggest the deck is deflecting
- Outlets that hold water back
Anyone responsible for a site like St Aidan's Voluntary Controlled Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- Which viewpoints they use to see the roof
- Which limits apply to the survey
- Whether you get a written report with photos
- Their report turnaround times
Tips that help
Getting the most from a flat roof survey starts before we arrive and carries on afterwards. Some tips:
- Watch the ceilings below the flat roof for stains
- Note the date and type of any roof work
- Keep outlets clear of leaves and moss
- Keep people off the roof unless they need to be there
Many people send the report to two or three roofers for quotes. With each roofer working from the same list, comparing quotes is simpler. It is your choice who carries out the work and when.
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.
FAQs for Stroud Green
How do I find out if my home in Stroud Green is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 carry out roof surveys in Stroud Green?
Yes, Stroud Green is one of the places we work. Every survey there gets the same written report with photographs.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
How many surveys have you done?
Over 20 years and more than 5,000 surveys.
Will this cover the whole house?
No. It is a survey of the flat roof. It is not a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. Many buyers use it alongside a building survey.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
How long is the visit?
It typically takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You will then get the report by email.

How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours for most houses, and about three to four hours for a commercial roof. In a London area like Stroud Green, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from ground level, windows, the loft and, where it is safe, the roof itself.
- You let us know about the roof, its covering if you know it, and any leaks.
- We check the roof from wherever it can be seen safely.
- 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.
- The findings are written up with photographs and recommendations and emailed to you.
Before the survey
- Move anything stored under the loft hatch
- Have any questions written down, so nothing gets missed
- Have keys ready for side gates, garages or roof access doors
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us.

Roof by roof
Single-ply membranes
Single-ply relies on its welded laps staying sound. We look at seams, corners and the joints around outlets and upstands.
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.
What affects the cost of flat roof surveys
What a survey costs depends on the time and equipment it needs. That comes down to:
- Height and safe access
- Extra roofs, like extensions, dormers or garages
- The size of the roof
- Features like valleys, chimneys, dormers and parapets
