How a flat roof survey works in Stonebridge Park
Our Basic Survey, from £150, gives you a visual inspection with photographs and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. On a flat roof, moisture readings can help show whether water has got under the covering. Larger commercial roofs are quoted for their size. Typical surveys look at dips that suggest the deck is deflecting and water getting in at rooflights, across EPDM rubber, GRP fibreglass and mastic asphalt.
Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Stonebridge Park, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

Before and after the survey
There is plenty you can do without going near the roof. Here’s what helps most:
- Clear roof outlets and gutters each autumn
- Keep people off the roof unless they need to be there
- Treat rooflights and old sheeting as fragile
- File the paperwork for the roof and any repairs
If anything in the report isn’t clear, just ask us. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, so you can talk the findings through.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
How we price flat roof surveys
All our prices include VAT. The things that change the price are:
- Extra roofs, like extensions, dormers or garages
- Height and safe access
- Basic, Standard or Premium
- Commercial roofs and larger buildings
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.
Getting in touch
The more you tell us, the easier it is to price the survey. When you contact us, it helps to mention:

- Any stains, drips or damp patches you’ve seen indoors

FAQs for Stonebridge Park
Is parking a problem for a survey in Stonebridge Park?
Parking in Stonebridge Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Does a conservation area affect roof work in Stonebridge Park?
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.
Can you test old roof sheets for asbestos?
Asbestos testing isn’t part of our survey. Where a roof has materials that might contain asbestos, such as old cement sheeting, the report flags them and recommend a specialist asbestos surveyor.
How experienced are you?
More than 5,000 surveys over 20+ years, across London and South East England.
What happens after the survey?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Will you walk on the flat roof?
We inspect from wherever is safe: on the roof where it’s safe, and from windows, nearby vantage points and inside. Fragile rooflights and fragile sheets are never walked on.
How do I book a survey in Stonebridge Park?
It is easiest to ring 07833 053749 or drop us an email. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run on any day of the week.
Flat roofs in Stonebridge Park
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. There are several hotels within about a mile and a half of Stonebridge Park, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
If you live in an older home near St Michael the Archangel, the joins between later flat roofs and the old walls are where problems usually start. Hotels and guest houses near Stonebridge Park can’t easily close rooms for a leak, so it’s worth knowing the roof’s condition. Anyone responsible for a site like Our Lady of Lourdes RC Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

The survey, step by step
The aim of the visit is simple: to look at the flat roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. For a visit in Stonebridge Park, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from ground level, windows, the loft and, where it’s safe, the roof itself.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Where there’s safe access, we check the ceilings and spaces below for signs of water.
- You get a written report with photos and our recommendations.
Before the survey
- If it is not your property yet, arrange access through the agent
- Tell us about any leaks, stains or damp patches you know of
- Keep pets inside or away from the areas we’re looking at

Why it is worth a survey now in Stonebridge Park
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. Surveying the roof in good time means work can be planned and budgeted around the business. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.
